Cooling Tower Blowdown Water Treatment

With water scarcity in many areas the reuse of cooling tower blowdown water was introduced.

Cooling tower blowdown water treatment. Many systems operate at two to four cycles of concentration while six cycles or more may be possible. Cooling tower blowdown cooling towers are widely used in industrial processes to eject heat. These maximize the overall recovery and minimize the volume for disposal. Any water source has various levels of dissolved and suspended solids.

Increasing cycles from three to six reduces cooling tower make up water by 20 and cooling tower blowdown by 50. Wet bulb temperature is measured by the thermometer which is wrapped in a cloth called soak. This process dilutes the system water mineral concentrations that steadily increase due to water evaporation. Offering unique benefits to our partners.

Cooling tower calculations terminologies. Cooling tower water treatment is an important part of many industrial processes. Ide s end to end integrated cooling tower blowdown water treatment solutions include high recovery reverse osmosis solutions that reduce reject volumes and complete thermal zld solutions. The specific configuration of your system will depend on several things including.

Wet bulb temperature of a. Aquatech s cooling tower blowdown recovery process can return nearly all of the blowdown volume for use as service or demineralized water. What type of cooling tower you have open circulating once through or closed loop. These concentrated cooling water blowdown streams are extremely rich in silica are characterized by higher hardness levels and include other organic loads.

As cooling tower water is cycled and evaporated it can become high in total dissolved solids tds. Avoiding biological contamination and maintaining proper water quality optimises cooling water s operational efficiency. Work with your cooling tower water treatment specialist to maximize the cycles of concentration. Range or delta t.

The make up water cooling tower blowdown water treatment presents several challenges due to the high salt concentrations and chemicals added in the cooling tower. Because the evaporative loss is water containing little to no solids the water remaining in the cooling tower becomes concentrated. Cooling tower blowdown ctbd treatment. The core of most microbiological treatment programs is feed of an oxidizing biocide to kill organisms before they can settle on condenser tube walls cooling tower fill and other locations.

A cooling tower water treatment system is an arrangement of technologies that remove damaging impurities from your cooling tower feed water circulation water and or blowdown.
