Food & beverage industry urged to adopt water best practice
The document, Process water and wastewater treatment in the food industry , points to the vast volumes of water used in food and beverage production and urges companies to do more to offset risk.
The food and beverage industry uses vast volumes of water, and treatment of process water and wastewater is essential to every production plant.
These are complex and costly processes, with every site required to meet specific local health & safety and environmental discharge regulations.
“There are significant reputational and financial consequences of putting people, products or the environment at risk through poorly managed systems and processes,” said Dale Kavanagh, industrials and business development manager, from Watson-Marlow Fluid Technology Group (WMFTG). “Yet there are practical steps companies can take to tighten their procedures and make their processes more efficient.”
Process water - used for food washing and preparation, pasteurisation, cleaning of equipment, steaming and sterilisation, or as an additive or stabiliser - accounts for the largest water use in the food sector, around 31%.
At the other end of the production line, wastewater must undergo high levels of treatment prior to discharge or reuse.
Across the world legally binding environmental regulations, such as the European Water Framework Directive, the US Clean Water Act and the Australian National Water Initiative are in place to protect rivers, lakes, estuaries, coastal waters and groundwater from pollution.
They stipulate treated effluent must meet high quality standards before being released into the environment. Food and beverage companies in breach of water quality requirements risk prosecutions and large fines and even having their discharge permits revoked.
“Water and wastewater treatment are critical to safety and efficiency in food and beverage processing plants and must be maintained to a high standard,” added Kavanagh. “Selecting equipment that is reliable, effective and easy to operate and maintain is especially important in a hazard-critical area like chemical dosing, where the risk of human error has to be minimised.”
