Carbon Regeneration

Definitions: Once Activated, carbon becomes saturated and turns into spent carbon having lost its absorption characteristics and can’t be used in filtration system and in order to bring it back to its original form and make it reactivated...

CO2 Dosing System

Desalinated water is poor in terms of minerals, making it corrosive and unpalatable. A certain degree of remineralization is necessary in order to overcome these problems. A commonly used remineralization process is to pass desalinated wate...

Coagulation for Water Treatment

 The primary purpose of the coagulation for water treatment, or the flocculation process, is the removal of turbidity from the water. Turbidity is a cloudy appearance of water caused by small particles suspended therein. Water with little ...

Cold Lime Softening

COLD LIME SOFTENING Cold lime softening, also known as Clark’s process, is used to reduce raw water hardness, alkalinity, silica, and other constituents. This helps prepare water for direct use as cooling tower makeup or as a first-st...

Cooling Tower Packages

A cooling tower is a heat rejection device, which extracts waste heat to the atmosphere through the cooling of a water stream to a lower temperature. The type of heat rejection in a cooling tower is termed “evaporative” in that it allow...
