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.

Ceramic membranes: High filtration area packing densities improve membrane performance Ceramic membranes: High filtration area packing densities improve membrane performance

New tubular ceramic membranes have been developed that provide a high packing density of the filtration area. These new ceramic membrane filter elements have been proven in case studies in oily wastewater treatment applications. Steffen Heidenreich and Winfried Michell of Pall Filtersystems GmbH describe the findings.

Wastewater: Treating wash water from paint removal

The shipping industry is required to treat wastewater to comply with increasingly strict environmental legislation. A solution was needed which could quickly and efficiently treat and dispose of the washing water used in paint removal. A filter station was developed with a compact filter system which combines filtration and briquetting in one device.

Reverse osmosis: Salt extraction from deep well aquifers Reverse osmosis: Salt extraction from deep well aquifers

Salt water intrusion in the local wells meant a wastewater treatment plant in the Village of Tequesta, Florida, US, required a desalination system. After soliciting bids from a variety of engineering firms, local officials chose two RO systems which subsequently required no cleaning in the eight years since installation.
