Facility Survey to determine Water treatment program

Companies using cooling towers to remove heat for cooling large buildings and from industrial process, should know that there are several issues that can surface during the cooling tower water treatment process that we see on a regular basis. Because these issues occur often, it’s important to have an appropriate water treatment program in place to protect the HVAC equipment and you time and resources down the line.

Keep in mind that these issues will vary depending on whether your cooling tower is an open recirculating system, once-through, or closed recirculating. 

At Express Cooling Towers Services, we will use our expertise to solve your HVAC water treatment needs, during our site survey we will determine important factors that will shape the degree of the water treatment program. Below are some of the steps that will be conducted during the survey to determine which chemical treatment program is right for you.

Since cooling towers remove heat by the process of evaporation, it’s no surprise that they, in turn, can use lots of water to make up the difference. Depending on the quality of makeup water being added to the cooling tower and the operation efficiency of the unit, large amounts of solids can remain after evaporation occurs, causing an increase need to "blow down" or remove solid waste and dissolved solids buildup from the circulation water before it has a chance to scale or corrode equipment.

When blowdown occurs, circulation water and treatment chemicals are also lost along with the solid waste, so it’s important to monitor this closely. If your cooling tower requires too much blowdown, it could be an indication that the water treatment system isn’t running as efficiently as it could be or feeding the cooling tower  an effective cooling tower water treatment system will provide the right quality of water to your cooling tower, the correct circulation chemistry , allowing it to run efficiently, avoiding problematic deposition, and maintaining a manageable amount of blowdown. This, in turn, helps conserve the amount of any makeup water or chemicals needed and results in a higher-solid waste.

CYCLES OF CONCENTRATION:

We test the make up water to determine the cycles of concentration allowed to decrease the amount of water the cooling tower uses and to reduce operating costs,as the quality of the source water, chemistry of the makeup water, and type of cooling tower being used will dictate what treatments are necessary to achieve the best cycle of concentration for your facility.  

• Improved feed water filtration
• Higher-quality side-stream filtration
• Increased cycle of concentration
• Maintaining better makeup water chemistry by removing scale forming and corrosion causing impurities
• Change or closely manage the cooling tower feed chemistry program
• Better cooling tower control by Minimizing blowdown monitoring conductivity
• pH/alkalinity control to minimize scale formation
• decreasing feed hardness, iron, and silica
• manage microbial growth

MONITORING EQUIPMENT:

We will determine water treatment monitoring, control and dosing equipment to better support the water treatment program at the site.

• Walchem, Pulsafeeder, Advantage Control
• Chemical feed pumps
• Flow meters, Flow switch
• Water meter, Pulse Water meter
• Water treatment Bypass System
• Coupon Rack/Steel and copper coupons
• Chemical spill containment

WATER TREATMENT CHEMICALS:

Depending the make up water chemistry we will determine the types of inhibitors microbiocides will best suited to treat the water.

• High performance phosphonate based corrosion and scale inhibitor for cooling water systems
• Controls the corrosion of steel, copper and brass
• Contains an effective dispersant
• Environmentally friendly, biodegradable
• Low toxicity
• Excellent water hardness corrosion control
• Stable to chlorine and bromine at the levels normally found in cooling water systems
• Controls the formation of scale
• Compatible with most cooling water treatment products 
• High performance corrosion inhibitor
• Suitable for closed chilled water and low pressure heating systems
• Excellent protection for steel, copper and other non-ferrous metals
• Ideal treatment for closed chilled water and low pressure heating systems
