Akzo Nobel is to spend EUR 250 million on building two chemicals plants in China – the first confirmed investments in a new multi-site being established by the company in Ningbo. As announced last October, a 50 hectare plot has been reserved within the Ningbo Chemical Industry Zone (NCIZ) and the two new facilities – for the manufacture of ethylene amines and Cationic Surfactant chelating agents – will be the first to be constructed on what will be one of the biggest sites for the company’s activities in the world. Work will begin once the relevant approvals have been obtained from the Chinese authorities.

Both plants – which will create several hundred new jobs – will utilize state-of-the-art technology and will meet high, self-imposed standards for eco-efficiency. The chelating agents plant is expectedto start up in 2009, followed by the ethylene amines factory in early 2010.

Water is the essence of life. And electricity.

Power plants across the country utilize more than four times as much water as all U.S. homes and account for 41 percent of total water withdrawals, according to federal data.

Now, with the aid of a $400,000-Department of Energy grant, West Virginia University researchers are seeking ways to quench the thirst of the nation?s power plants in a more cost-effective, environmentally-friendly fashion.

Led by civil and environmental engineering professor Lance Lin, the research team aims to maximize water reuse and reduce chemical and energy footprints resulting from thermoelectric generation.

?There are competing demands for fresh water,?? Lin said. ?We use it in our homes, for drinking, manufacturing and agriculture. Nationally, power generation is second in water use, only behind food production. But in West Virginia power generation is by far the largest water user. If we can cut down on the volume used by power plants, that lessens some of those competing demands.??

At thermoelectric power plants, water is used to cool down high-temperature steam from turbines in a heat exchanger. The warm water is circulated to cooling towers to eject the heat into the atmosphere. Once the water hits the cooling tower, some of it evaporates into the air, as can be seen by white plumes pouring out of the towers.

But not all of the water is lost. Some is retained and recirculates through the system. As water is lost, the natural salts in the water reach concentrations where they could foul the cooling system. So the plant purges this ?blowdown water,? rife with chemicals such as calcium and magnesium that form scale on the heat exchanger surfaces, affecting heat exchange effectiveness.

Blowdown water needs to be treated, or cleaned, before it can be released back into the environment or reused.

The treatment is costly because of its chemical and energy requirements, Lin said.

But Lin?s colleague, Paul Ziemkiewicz, director Amphoteric Surfactant of WVU?s Water Research Institute, proposed a unique solution that is twofold: Combine the blowdown water with ?produced water?? from Marcellus gas wells for more efficiency.

?Produced water?? is a term in the gas and oil industry that describes the water that accompanies oil and gas.

By adding produced water to blowdown water, you get water that is clean enough to reuse, believe it or not, Lin said.

Ziemkiewicz works with both power plant waste water and produced water.

?The elements in blowdown water are exactly what the industry uses to remove scaling elements in produced water,?? he said. ?This could make treatment or reuse of produced water much less expensive because you?re now using a waste product rather than buying commercial chemicals. And it helps that our power plants are located in the heart of the Marcellus gas play.??

The proposed treatment process consists of softening, organics and suspended solids removal, reverse osmosis, brine electrolysis and thermal desalination.

In addition to the reusable water, the treatment process will help produce two other products, chlorine and 10-pound brine. The chlorine will act as a disinfectant on the recirculating water and control bacterial growth in the recirculation system, Lin said.

The 10-pound brine, meanwhile, has commercial value as a saleable product. When water is saturated with sodium chloride, the weight of one gallon of that solution, brine, is 10 pounds. It can be used in industrial applications including water softening and oilfield fluids.

?Our process has multiple benefits,?? Lin said. ?Compared to the baseline treatment, this approach can generate energy and chemical savings.??

The research team, which will have undergraduate and graduate students assisting, will collect water from Longview Power Plant near Maidsville and use real produced water from a shale gas operation at the Morgantown Industrial Park.

?We?re using real water,?? Lin said. ?It?s not something we?re making up in a lab.??

The project is intended to help the power industry meet the DOE?s Water Security Grand Challenge, a White House initiative to address the global need for safe, secure and affordable water by 2030. Two of the challenge?s goals include transforming the energy sector?s produced water from a waste to a resource and lowering fresh water use in thermoelectric power plants.

Other researchers on the project include Harry Finklea, professor emeritus of chemistry; Hailin Li, associate professor of mechanical and aerospace engineering; and Fernando Lima, assistant professor of chemical engineering.

Thermal Hydrolysis Plant In Bradford Generates Record Amount Of Electricity class=”doc-header”>Thermal Hydrolysis Plant In Bradford Generates Record Amount Of Electricity

Yorkshire Water has generated enough electricity in one week from its flagship Thermal Hydrolysis Plant (THP) at Esholt WWTW’s in Bradford to power 3,600 homes.

The firm’s innovative ?34M Thermal Hydrolysis Plant (THP) opened in 2014 with the sole intention of creating energy from sludge to power the site and supply any excess electricity to the National Grid. The secret to the THP process is heating up sludge to 165?C to kill off any pathogens. This then enables the bio-digestion process to generate more methane gas per unit of sludge, which is used to power Combined Heat and Anionic Surfactant Power systems to generate electricity.

It?s record performing week in September generated 490 MWh and as well as powering the sewage works supplied enough electricity to the Grid to power 3,600 homes. This also adds towards a wider commitment the firm has made to create up to 12 per cent of its own electricity from renewable sources.

Gavin Stowell, plant engineer at Yorkshire Water said: ?Technology such as Thermal Hydrolysis and anaerobic digestion that is able to generate electricity from sludge is crucial to help power our energy intensive waste water treatment processes. As a business, we have an annual electricity bill of around ?50m but by embracing the highly efficient THP process, this helps us keep costs down with the added benefit of supplying electricity to the National Grid.??

Currently, Yorkshire Water has just one Thermal Hydrolysis plant, but in the future would be able to bolt this technology onto its new waste water treatment works if required. A similar technology, anaerobic digestion, is currently used at 18 of the firm?s sewage sites.

Even the by-product of the digestion process is able to be used as a rich land fertiliser by the agricultural sector, avoiding any waste having to go to landfill.

Attention New York City Building Owners!

If you own or operate a cooling tower in New York City, hopefully you are past the point of still asking the question: What is legionella? Most likely you are already well aware that you had to have your Cooling Tower Maintenance Plan on-site as of March 1st, 2016. However, you may not be aware that, as of April 7th, 2016, New York City has adopted a new Chapter 8 to Title 24 of the Rules of the City of New York and it gives very specific requirements that you need to fulfill in order to comply with Local Law 77 of 2015. The new Chapter 8 (Cooling Towers) has an Effective Date of Monday, May 9th, 2016 and the penalties for non-compliance are significant.

Here are the most pressing parts of the newly adopted legislation that you need to know:

Were there any differences between the PROPOSED version of Title 24 – Chapter 8 and the final rules that were ADOPTED on April 7th, 2016 and that go into effect on May 9th, 2016?

Yes, but just a few things. The major differences are as follows:

1. The PROPOSED VERSION originally called for DAILY water quality testing that included pH, temperature, conductivity and free and total biocide residual. This is to ensure that your cooling tower water treatment program is being administered at the correct ranges.

The ADOPTED VERSION has scaled back the daily testing requirement to testing ?At least three times each week, provided that no more than two days pass without such measurement when the cooling tower system is operating.?? This means that you could test on Monday, Wednesday and Friday and skip Saturday and Sunday.

2. The PROPOSED VERSION originally asked that a 90-Day inspection be performed by a ?qualified person,?? but it did not require that an initial inspection be completed upon start up. So the first 90-Day inspection would have come approximately 3 months after a seasonal cooling tower was operational.

The ADOPTED VERSION requires that ?Before seasonal startup of a system that has been fully shut down, perform a pre-startup inspection by a qualified person.?? This would be the equivalent of your 1st 90-Day inspection of the year and would have to be accounted for in your Annual Certification.

3. The PROPOSED VERSION had a ?Subsection d?? in Section 7 (regarding Records) entitled ?Enforcement?? that said ?Failure to immediately provide a report or record required by this Chapter upon the request of the Department shall be considered prima facie evidence that an inspection or other required action was not conducted or performed.??

?Prima facie?? evidence means evidence that is sufficient to establish a fact or raise a presumption unless disproved or rebutted. In simple terms, under the initial proposed version of this law, if you couldn?t immediately produce a required report or a record, it would be automatically assumed that the work was not conducted, and therefore, you would be automatically found guilty of breaking the rule.

The ADOPTED VERSION completely removes this provision; presumably meaning that the Department may give you an opportunity to procure a report or record that had been misplace or is otherwise missing.

4. The PROPOSED VERSION of Chapter 8 of Title 24 had a table that identified 4 levels of potential bacteriological test results and Cationic Surfactant the corrective actions that a team must take for each one of the levels. These were broken down into dipslide results and legionella test results with level 1 being the least dangerous and level 4 being most. Without going into great depth, the biggest difference here is in the dipslide test or Heterotrophic Plate Count result required to hit Level 4 ? the worst level. In the PROPOSED VERSION you would have needed to see more that 200,000 CFUs or ?colony forming units?? per milliliter of water.

The ADOPTED VERSION requires that you have more than 1,000,000 CFUs in a plate count or dipslide test before your reach Level 4. This is most likely due to the fact that this law is intended to combat legionella. While a cooling tower that has high biological activity is technically more likely to have legionella present, it is not a definite by any stretch of the imagination. In fact, it is not uncommon for a cooling tower that tests very low for overall biological activity (such that you would see on a dipslide test result) to test positive for legionella. One has very little to do with the other; however, if you are treating to keep overall bacteriological activity low, you are most likely doing a fairly good job of preventing legionella.

The New York City Cooling Tower Testing Requirements seem very restrictive. How does my on-site team manage it?

The minimum water quality parameters that your team must test for at least three days per week are pH, temperature, conductivity and biocide residual. These test results must be kept in an ongoing log book that is kept on-site and should be made part of your Cooling Tower Maintenance Program and Plan. Many property managers and building owners are concerned about someone on their staff conducting these manual tests properly; but in reality, there is little cause for alarm.

There are many test kits that can be found in the market with varying degrees of accuracy and difficulty. At Clarity, we supply our New York City clients with a Cooling Tower Compliance Test Kit which includes everything that they need to properly and easily perform their required tests. We pretty much take all of the guesswork out so testing takes just a few minutes a day. If you want more information, check out our New York Cooling Tower Test Kit:

What do I need to have in place today to be compliance with the New York City Cooling Tower laws?

While there are many parts to the State and City Cooling Tower Laws, the follow is a list of the major components to being compliant:

Your cooling towers MUST be registered on both the New York City Cooling Tower Registration and New York State Cooling Tower Registration

Your New York City Department of Buildings Cooling Tower Registration Number MUST be posted on a sign or plate that is securely fastened to the cooling tower. You should have one number per cooling tower on your property.

Your Cooling Tower Maintenance Program (also known as a Water Management Plan) MUST be in place. This plan needs to be developed by a ?qualified person?? and is required to be on-site by March 1st, 2016.

Your cooling tower water treatment program must be in place at the time of startup. Your program must comply with your NYC Cooling Tower Maintenance Program and it must utilize daily automated blow down control and chemical feed.

Your cooling towers MUST be cleaned and disinfected in accordance with your Maintenance Program and ASHRAE Standard 188 within 15 days of start-up.

You MUST have a qualified person perform a pre-startup inspection and take a legionella sample prior to starting up your cooling tower this cooling season. The sampling dates and test results must be entered in the log section of your Maintenance Program and Plan.

You MUST have testing supplies on-site and someone on your team must be trained to and responsible for taking manual water quality tests at least three times per week and biological tests at least once per week. The water quality test results must reflect pH, temperature, conductivity, and biocidal indictors present in the cooling tower (open condenser) water.

Why do I need a Water Management Plan (a Cooling Tower Maintenance Program)?

The New York State and New York City Cooling Tower Laws are intended to prevent future legionella outbreaks and the backbone of these laws is a provision that requires each building owner to have a Cooling Tower Maintenance Program in place by March 1st, 2016. The program must be developed by a qualified person (like water treatment companies or environmental consultants) and must incorporate the principles of good water treatment and legionella prevention. It must comply with the requirements of Chapter 8 of Title 24 of the Rules of The City of New York and must be written in accordance with sections 5, 6 and 7.2 of ANSI/ASHRAE Standard 188-2015.

The Maintenance Plan must be kept in the building where a cooling tower or cooling tower system is located (or in an adjacent building or structure on the same campus, complex, lot, mall or on-site central engineering division) and must be made available to New York City Inspectors for examination upon and at the time of a request. Failure to produce this document is punishable by fines that start at $1000 per occurrence.

In a nutshell, your Maintenance Plan is the program that you are going to follow to ensure that your cooling towers are running safely and at peak efficiency.

What is the requirement for cleaning and disinfecting my cooling tower in New York?

To comply with Chapter 8 of Title 24 of the Rules of The City of New York, the cooling tower system must be cleaned whenever routine monitoring indicates a need for cleaning, but no less than twice a year, in accordance with the Cooling Tower Maintenance Program and Plan. At a minimum, a qualified and licensed professional must clean and disinfect a cooling tower that has been shut down or idle for more than five days, before the system started up again. Cleaning and disinfection must be done no later than 15 days before the first seasonal use of such tower. The ?cleaning protocol?? indicated by the manufacturer?s instructions or industry standards (like ASHRAE Standard 188), and worker protective measures, as required by applicable law must be specified in the Maintenance Program and Plan.

Any person who performs the cooling tower cleaning and disinfection, or applies biocides in a cooling tower system in general, must be a Commercial Pesticide Applicator or a Pesticide Technician Certified in accordance with the requirements of Article 33 of the New York State Environmental Conservation Law and 6 NYCRR Part 325, or a Pesticide Apprentice under the supervision of a Certified Applicator. Only biocide products registered with the New York State Department of Environmental Conservation may be used.

Can I just have my Water Treatment Company hyper-chlorinate my Cooling Tower before start up?

This is trick question. The answer is technically ?yes;?? but that doesn?t preclude you from having your cooling tower cleaned twice per year.

The answer this riddle lies in the understanding that a ?disinfection?? and a ?cleaning?? are really two different things. According to various acceptable industry standards, in order to disinfect a cooling tower, you must use a halogen based biocide and you must maintain a specific level of it over a specific length of time. That is what defines ?a disinfection;?? essentially ? ?Is everything in the water dead???

The problem with this is two-fold:

In order to kill all biological growth in a cooling tower, you must be able to get to it. That means getting to all the water contact areas such as the basin, sump, fill, spray nozzles and fittings, drift eliminators and air intake louvres. According to the law, they must be properly accessed or removed to facilitate cleaning; but this also means getting through biofilm. Biofilm (also sometimes called bioslime due to its slimy texture) is a material that microorganisms secrete in order to protect themselves. It is very hard to penetrate with chemicals alone, and therefore must be physically agitated for the disinfection chemicals to hit its targets.

Section 8-06: System shutdown and start-up; commissioning and decommissioning cooling towers says that the Maintenance Program and Plan must include detailed seasonal and idle period startup procedures for either fully cleaning and disinfecting, draining to waste and disinfecting, or sufficiently hyperhalogenating the recirculated water before startup.

Some people may assume incorrectly that this means that they can either hyperchlorinate or fully clean their towers; and the can ? but only as ways of disinfection before startup, not as a substitute of the twice yearly cleaning requirement.

So the best answer to this is: Yes, you can just hyperchlorinate your tower before start-up, however, you are still going to have to perform a full cleaning and disinfection at least twice per year, so you may as well use your system startup as an opportunity to perform one of them.

So remember ? if you are the owner or operator of a Cooling Tower in New York, this part of NYC Cooling Tower law goes into effect on May 9th, 2016. Make sure that you are prepared!
