Drinking water treatment - Water and Wastewater - Drinking Water
Drinking water can be produced from any natural sources like groundwater, lakes and rivers (surface waters) or seawater. Drinking water standards are set by the World Health organisation or by the European Union. Drinking water must be free of suspended solids, microorganisms and toxic chemicals. Mineral concentration recommendation vary from country to country but most of the minerals have a maximum concentration recommended to ensure safe, equilibrated and pleasant water to drink.
For municipal drinking water, a special focus is carried on the corrosivity and scaling potential of the water to maintain distribution piping in good shape. Typical pH 8, TAC 8 and TH 8 are applied, when possible.
For bottled water, taste can vary upon calcium, magnesium, sulfate and iron content.
