Water Treatment

Old Bridge Chemical’s copper and zinc are used frequently in water treatment for drinking water, industrial water supply, personal pond care and for swimming pools. Copper is widely used for this purpose due to its natural long-term antimicrobial potency and algae control.  Zinc is primarily used in water treatment for corrosion control of water carrying pipes.

Our copper and zinc products are NSF approved.  Our copper sulfate is EPA and PMRA certified for use as a pesticide.  Our copper sulfate is also certified for use in organic pest control.
