Water treatment

The challenges of water treatment vary widely, depending primarily on the quality of the water to be treated.

Given plentiful freshwater and groundwater resources and minimum contamination, basic infrastructure generally offers a perfectly adequate and cost-effective water treatment solution. Screening and simple sand filtration removes water-borne impurities, while disinfection combats unhealthy pathogens.

Additional impurities in water sources demand additional remedies. For example, if agricultural pollutants are identified in a water source, activated carbon absorption may be required to remove dissolved organic compounds, sometimes in combination with ozone treatment. Alternatively, if nitrates are present in a water source, ion exchange, distillation or reverse osmosis treatment can effectively reduce concentration levels to World Health Organizations (WHO) standards. Other mineral and organic contaminants may call for further filtration, pH adjustment or chemical additives.
