Cooling tower make-up water
Water is widely used as a medium for cooling, due to its good heat transfer capacity.
Depending on water source and its properties, treatment might be required. Depending on the type and material of the cooling towers, several parameters shall carefully monitor to prevent corrosion, fouling and scaling. While recirculating water and due to evaporation losses, the amount of dissolved minerals increases in the cooling tower.
Figure 1 - typical cooling tower scheme
Cooling towers manufacturers typically provide limiting and recommended parameters, like conductivity, total dissolved solids, pH. Therefore, water treatment is always required in the make-up water of a cooling tower.
Water treatment of make up water will depend on the source of water and CT manufacturer requirements: suspended solids removal, dissolved solids removal, softening, pH adjustment, dosing of biocides for bacterial control, dosing of anticorrosion agents.
Common water sources are well water, surface water, reused waste water and sea water.
As water shortage has been increasing and stricter regulations for blowdown waste water have been imposed by environmental policies, high efficiency technologies have been continuously developed to meet current industry needs.
Lenntech develops innovative solutions with the combination of a wide range of technologies for cooling tower make-up water treatment according to the source of water and Cooling tower needs: ultra-filtration, activated carbon, multimedia filtration, reverse osmosis, closed circuit reverse osmosis, ion exchange softening, electro-dialysis reversal, chemical conditioning.
Dissolved solids removal in the make-up water can increase the cycles in the cooling tower, reduce water consumption up to 50% and consequently reduce the cooling tower blow down (waste water), as well as reduce the chemical consumption for water conditioning.
Lowering the chemical consumption in the make-up water will contribute for a less polluted blow down waste water. The cooling tower blowdown water treatment (new page, create a link) can help to optimize the cooling tower consumption, our solutions are suitable for reducing cooling tower operational costs and water footprint.
Benefits of make-up water treatment include:
- more stable water quality,
- lower fouling and corrosion,
- reduction of chemicals used,
- Process optimization.
