Ammonia is used in several areas of water and wastewater treatment, such as pH control, in solution form to regenerate weak anion exchange resins, in conjunction with chlorine to produce potable water, and as an oxygen scavenger in boiler water treatment.
On an industrial scale is usually accomplished by the treatment of acidic solutions by the manual or automated addition of a basic (alkaline) compound.
Ammonia is used to increase pH in Pharmaceutical, Ore Flotation & Food Industries.
Ammonia is commonly used as a neutralizing agent for acid discharges associated with coal mining. The continuous treatment method is used where vapor is injected at the entrance channel to the pond where it is evenly dispersed into the pond.
Water Chlorination is a waste-water treatment process that uses continuous chlorine treatment to achieve high standards of bacteriological quality and improvement in other water treatment processes.
