Water Treatment Firms

When selecting a water treatment firm to work with, customers often wonder which base criteria will make the most difference. All things considered, many have found that selecting a member firm from the Association of Water Technologies is a great place to start (www.awt.org). Next, from within the AWT, look further to firms who have employees on staff that have achieved the important CWT distinction. The Certified Water Technologist (CWT) has undergone the industry’s most rigorous technical proficiency accreditation, and possesses the wisdom, business ethics and experience to support program development and coverage in your area. You will be assured of high quality and professional representation.

Saving Money on your Facilities Water Bill

Many Pubic Water/Wastewater Providers offer “sewer abatement programs”. These programs are typically for irrigation, humidification, and cooling tower systems. The reason these programs are offered is because these systems create little or no waste stream. “Why pay a sewer charge when you are not putting anything into the sewer”. In the case of irrigation systems and humidification boilers, you will be required to install one dedicated water meter for each system. You will be charged for the water but will receive no sewer charge. In the case of cooling towers, you will be required to install two water meters. One meter will be for the makeup water to the tower and the second will be on the bleed/drain line. In this case, you will only be charged a sewer charge for the amount of water that you bleed from the cooling tower to control the dissolved solids. If this program is available from your supplier, you will see a significant reduction in your overall water/sewer bill. If you are not already taking advantage of this type of abatement program, it’s worth taking a few minutes to call your municipal provider to see if a program is available.

Propylene Glycol

Propylene glycol is being specified on a more frequent basis to support freeze protection and heat transfer in the HVAC universe. There are many brands and what seems like a plethora of options available. Therefore, there is much confusion in the market as some glycols may even be offered on a simple commodity basis. Smart consumers will recognize the subtle differences. Suppliers of glycol can be differentiated by considering several key factors. First, flexibility in the formulation needs to be the primary consideration. Depending upon project scope, the glycol being added must match in concentration, color, and most importantly inhibitor pack. For most formulators, managing these variables with one formula on range is extremely difficult to accomplish, and hence they will tend to market their “brand” as the best. Here the inhibitor pack is essential, as it must be suitable for the unique operating conditions of a given system, and be selected to match and protect system metallurgy. Quality suppliers of glycol will offer capable laboratory support, specialized delivery approaches, and field installation services. While simple “glycol” may seem like a commodity item, it is not. Doing a little research on supplier options in your geography can save time, effort and big dollars down the road.

Green Buildings – Green Industries

Much information has been put forth concerning the need for green, sustainable technologies to protect our planet and our indoor/outdoor environments. Unfortunately, when it comes to a conversation about chemical water treatment for HVAC and Industrial systems, some have suggested that since ‘chemicals’ are employed, the industry cannot possibly be Green. This sentiment cannot be further from the truth. In fact, the Water Treatment industry is at the very foundation of Green. Building managers, Plant Engineers and Facility Managers will be first to confirm that water treatment is the primary driver to energy efficiency, water conservation, and capital preservation in each of their operations. For it is the consistent application of a professionally-designed treatment program that allows energy and water resources to be used efficiently in our buildings and factories. Without a carefully applied program, electric and fuel meters spin faster, water is wasted unnecessarily, and systems fail sooner. In fact, a well-directed chemical water treatment program will even ensure that the people (human resources) who work in the building and those dedicated to the operation itself, are not only kept safe, but can do their jobs efficiently, with the least amount of energy consumed. Get a good program from a reputable supplier. When in doubt ask for a CWT (Certified Water Technologist) working for a member firm of the Association of Water Technologies.

Why do you need to test for Legionella?

Water Hygiene is the responsibility of Building Owners, Property Managers and Maintenance Departments to reduce the risk of Legionella in any water system with the potential for human contact. The recently ratified ASHRAE 188 standard establishes the minimum requirements for a buildings risk management plan. These practices have already made their way in to legislation and guidelines. New York became the first State to pass laws requiring that building owners and healthcare facilities develop a Water Management Plan. The CDC has issued a tool kit based on the ASHRAE standard to help facilities determine the best course of action to keep building occupants safe. And the CMS has issued a requirement that all hospitals take action to reduce the risk of Legionella in Healthcare Facility Water Systems. Regular testing for the Legionella Bacteria in water systems is a component of a successful Water Management Plan to verify the effectiveness of a Facilities control measures and demonstrates a pro-active approach to reducing the risk of Legionella contamination.
