COOLING WATER TREATMENT

We understand that the water treatment of cooling towers is an integral part of process operations in many industries, with the possibility of productivity and product quality being adversely affected by scale, corrosion, fouling and microbiological contamination.

These water treatment problems can be very costly when they cause the loss of heat transfer in the cooling tower, equipment failure, and health and safety concerns. VASU-NORTHMAN uses a unique engineering approach, looking at your cooling tower and water treatment systems from mechanical, operational and chemical angles. We can provide best-in-class cooling tower water treatment solutions tailored to your cooling tower systems.

BOILER WATER TREATMENT

Northman starts water treatment with boiler water treatment, and more than 15 years ago, we began treating boilers for industry. And that long-term commitment to developing the most innovative boiler water treatment technologies in the industry continues today. It is a result of our desire to improve your competitive advantage and decrease your total operating costs.

A single day of lost steam production can cost you much more than the cost for one or two years of our boiler water treatment programs. While our program costs may not significantly impact your bottom line, we understand that our results do, and we are passionate about helping you produce reliable, safe, and cost-effective steam. Successful boiler operation requires a total system approach to:

• Prepare feed water before it goes to the boiler
• Protect and keep the internal boiler surfaces clean
• Maximize condensate return

We can perform detailed system audits and diagnostics in association with our principals who are leaders in water and steam to prescribe the best chemical, steam distribution and service programs to maximize your boiler system performance and efficiency through an effective boiler water treatment program. Through utilizing our innovative programs, we can help you achieve water and energy savings, asset preservation, and increased plant reliability and safety.

POLYELECTROLYTE – WASTE WATER TREATMENT

VASU-NORTHMAN understands that effective primary waste water treatment is critical to your plant operations, whether you are discharging directly to a municipal wastewater treatment system or treating prior to your own biological wastewater treatment system. Optimizing the performance of treatment chemicals and equipment can dramatically minimize overall costs and maximize your return on investment, and we can provide creative solutions to help meet your most stringent water quality requirements.

Solids dewatering is the second-highest cost area in a wastewater treatment plant, second only to electrical utility costs. Effectively optimizing the performance of dewatering equipment and chemicals can dramatically minimize the total cost of operation and maximize your return on investment. In addition, as processors endeavour to meet stringent regulatory requirements, solids handling and disposal continues to be one of the most important areas requiring creative, sustainable-technology solutions.

We also understand that effective secondary wastewater treatment is critical to your plant operations. We can provide you with creative treatment chemicals and equipment solutions, helping you meet your most stringent water quality requirements and maximize your return on investment. Our programs typically focus on the following and can help you with:

• Improving overall plant economics
• Increasing operator capabilities and effectiveness

AHU / AC COIL CLEANING

Answering questions about how to clean A/C evaporator coils usually begins with why to clean them in the first place. The evaporator coil in your air conditioner is ground zero of the cooling process that keeps your work place comfortable throughout these long Louisiana summers. Cooling a house is all a matter of moving indoor heat energy outside. Installed inside the indoor air handler, the evaporator coil circulates refrigerant that absorbs heat from household air circulating through the ducts and conveys it to the condenser coil outside where it’s dispersed into the air.

Taking out the heat
The heat extraction process that takes place at the evaporator coil relies on a precise amount of refrigerant vapour flowing through the coil and clean coil surfaces to facilitate the efficient absorption of heat energy into the refrigerant. As these surfaces become coated with dust or the small air passages that allow air to pass through the coil are obstructed, the effectiveness of the heat transfer process begins to decline proportionately. The direct impact is on your ELECTRICITY BILLS.

It’s the humidity, too
Your work place cooling equipment is called an air conditioner instead of an air cooler because removing humidity from indoor air is an equally vital function of the evaporator coil. Moisture in the air holds heat and makes living spaces harder to cool. Conditioned air at low humidity levels cools more effectively and feels more comfortable. A dirty coil also underperforms as a humidity extractor, leaving rooms clammy and making cooling less effective.

To do it yourself
Coil cleaning chemical – VANIKLIN-WB is user friendly innovative approach for cleaning AHU / AC coils. By using any spray pump, you can clean coils which will not only increase cooling but also ensure control on your electricity bills.

RO ANTI SCALANTS

SPECTRAGUARD chemical "scale inhibitors," prevent mineral deposits from building on your membrane, causing fouling. Our VASU-PWT product line helps resolve these problems-and in almost every instance, at a lower cost than it would be to use ion exchange to remove hardness.

RO MEMBRANE CLEANING
When a membrane does need cleaning, our VASU-PWT chemical product line removes most foulants and restores performance in all types of membrane systems. We can provide you cleaning chemicals specifically formulated to remove mineral scale, insoluble scale, organic fouling or microbial residue.
