Water recycling in the brewing industry Water recycling in the brewing industry

Effluent should be recycled back into brewery operations with less reticence than is currently the case, according to South African wastewater specialists Talbot & Talbot. Throughout many parts of the world there are areas or entire regions where water is scarce and water quality highly suspect. In these situations beer quality is often compromised and production schedule disrupted. The use of properly treated effluent presents the brewer with a safer option and greater security of supply.
