Ammonia removal from wastewater

Drainage of untreated wastewater on surface water like rivers, lakes, oceans, and seas causes a big pollution problem. Many pollutants are acutely harmful to aquatic life and human health (e.g., heavy metals, pesticides, PCBs, dyes, N. compounds, etc…). Drainage of industrial effluent on drinking water sources poses a threat to human health especially if contains accumulated pollutants in human body and soil. Populations are exposed toheavy metals primarily through waterconsumption, but few heavy metals can bio-accumulate in thehuman body (e.g., in lipids and the gastrointestinal system) andmay induce cancer and other risks. To date, a few thousandpublications have reported various aspects of heavy metals indrinking water, including the types and quantities of metals,their sources and factors affecting their concentrations atexposure points, human exposure, potential risks, and theirremoval from drinking water. Many developing countries arefaced with the challenge of reducing human exposure to heavymetals, mainly due to their limited economic capacities to useadvanced technologies for heavy metal removal Hence, we must urgently pursue the necessary treatments, particularly for ammonia and its compounds, to protect the aquatic environment.There are several methods to treat ammonia in polluted water, each with its own advantages and applications. Here are some commonly used methods like: Air Stripping, Ion Exchange, and chemical treatment.
