Increased population and insufficient investment in infrastructure over the past several decades have left almost one-third of the world's people without access to clean water. With regard to the improvement of our drinking water, Bronkhorst products can play an important role in such areas as:

Precise dosage of chemical additives for optimal concentration at lowest health risk
Up to 30% reduction in additive consumption
Reduction in chemical concentration of additives in sewage water

Examples of applications

Preventing lead or copper precipitation
Iron and lime removal in drinking water
Effluent treatment of wastewater
Chlorination of drinking water
Dosing additives

Typical application in Water Treatment

Dosing additives to prevent lead or copper precipitation

Public water systems commonly add phosphates to the drinking water as a corrosion inhibitor to prevent the leaching of lead and copper from pipes and fixtures. Inorganic phosphates (e.g. phosphoric acid, zinc phosphate, and sodium phosphate) are added to the water to create orthophosphate, which forms a protective coating of insoluble mineral scale on the inside of service lines and household plumbing. The coating serves as a liner that keeps corrosion elements in water from dissolving some of the metal in the drinking water. As a result, lead and copper levels in the water will remain low and within the norms to protect the public health.
