The fresh water requirement for a cooling tower in a typical coal-based power plant is approximately 80% of the total consumption of water. These concentrated cooling water blowdown streams are extremely rich in silica, are characterized by higher hardness levels and include other organic loads. Aquatech has vast experience in recycle/reuse solutions for cooling tower blowdown and cooling tower water treatment.
Water from cooling towers attracts and absorbs airborne contaminants on a continuous basis. Typically, 85% of suspended solids in cooling water and hot water loops are smaller than 5 microns.
Scientific studies have shown that these small particles (5 microns and less) are the adherent contaminants fouling cooling tower water, chilled water and heat exchangers, thereby reducing your cooling system efficiency.

ISO 9001:2008 certified and turnkey experienced, WesTech stands ready to meet deadlines and assure minimal downtime with focused service.
Boilers and cooling towers share two major water related problems: deposits and corrosion. As steam is generated by a boiler or water evaporating from a cooling tower, dissolved minerals are left behind, increasing the concentration of these minerals. Additional minerals are introduced via the water added to makeup the water lost to steam/evaporation. Eventually, the minerals reach a level (or cycle) of concentration that will cause either loss of efficiency due to scale or damage from corrosion. This level can...
Those in the power generation industry know how critical a reliable, steady stream of high purity water is. For power generation, water is used in high pressure boilers, turbines and cooling towers. Water treatment for power generation is a vital process that requires a dependable technology. High purity water ensures proper operation of steam generation system and reduces blowdown frequency and use of boiler chemicals. High purity water is also able to better protect against erosion and damage to equipment.

Monitoring Biomass in (Cooling Tower) Waters through ATP monitoring
The TOXcontrol can be used for ATP monitoring. Currently our company is doing research for further developments for this application on the TOXcontrol.
Monitoring the microbial population of cooling towers is necessary in order to maintain the proper operation of the system. Conventional methods for monitoring microbial populations work by culturing microorganisms, a time-consuming procedure that requires days or even weeks of incubation before...
Chlorine dioxide is used as a biocide in many industrial water treatment applications including cooling towers, process water and mill water. Its selective oxidative properties usually results in lower dosages of ClO2 while also achieving improved microbial performance.
Cold Lime Softening: Hard water is water that has high mineral content. The name comes from the hard scale that forms when this water is boiled. It is not harmful to human health, but in the industrial setting it causes costly breakdowns in boilers, cooling towers, and other water handling equipment. The divalent cations Mg and Ca are the most frequently found minerals causing hard water. These ions enter water supplies by leaching from minerals in underground aquifers.
Controlling and preventing the growth of microorganisms in a cooling tower is extremely important and required to keep the system running at optimal levels. The presence of microorganisms will cause the system to breakdown and decreases the efficiency of the heat transfer. Typically oxidizing biocides such as chlorine and bromine have been used to treat cooling water. Unfortunately these chemicals are highly reactive with other chemicals and microbiological species found in the water. Chlorine dioxide however is...
More than 85% of contaminated suspended solids in water from cooling towers and in hot water loops, are smaller than 5 microns. These micron contaminates circulate through heat exchangers, chillers, and compressors, significantly reducing the system’s cooling ability.Even tiny scale fouling and particle formation reduces the heat transfer rate and increases the water pressure drop through the heat exchanger, condenser and pipes, resulting in an increase in energy costs.
A college operates four chillers with a cooling capacity of 1,600 tons. The cooling water system includes four individual cooling towers with a total water volume of 14,000 gallons. Scale and deposits became a serious issue under chemical treatment, and local effluent discharge regulations were requiring the water treatment system to be environmentally friendly.

MIOX’s patented Mixed Oxidant Solution (MOS) or Hypochlorite (HYPO)chemistries for cooling tower and cooling loop water disinfection improves safety, lowers general corrosion rates, increases performance, and saves money. The unique qualities of MOS lowers corrosion rates by 80% in copper and 50% in steel, resulting in a reduction of downtime, maintenance, and expense. Additionally, MIOX generators improve workplace safety by eliminating the handling and storage of hazardous chemicals while maintaining...
“Efficiently lowers algae, biofilm formation, bacterial counts and chemical consumption.” When temperatures are high, for example in cooling towers, a matrix of different microorganisms such as bacteria, fungi, EPS and algae can grow very rapidly. The disadvantages of biofilm formation in cooling towers can be enormous. Therefore water used in cooling towers needs frequent treatment and chemical shocks to keep levels of micro-organisms to a minimum.
Summary of areas where an Acme scraper strainer can be installed in industrial marketplace and automatic strainer application. The market niche for ACME scraper-strainers and application for strainers is for screen openings larger than .003 inches or 75 microns and goes up to a high end of 6 inch or 150mm particles. At the finer straining end of the ACME line, there is an overlap with the upper end of backwash-type strainers of various designs. As particle sizes grow larger, backwash units fail to compete because...
