Water recycling in the food and beverage industry
Water reuse in the food and beverage industry
| The food and beverages processing industry requires a huge amount of water. One of the main problems is the amount of wastewater continuously produced in the food plants. The water is used as an ingredient, a cleaning agent, for boiling and cooling purposes, for transportation and conditioning of raw materials. |
Spent process water in the food industry (salt content as el. conductivity <3000μS/cm and COD<700mgO2/l) can be desalinated and organics can be removed so as to fulfill the requirements for water reuse. Food industry standards specify that, spent process water intended for reuse (even for cleaning purposes) must be at least of drinking quality.
Regulations for other applications, such as boiler make-up water or warm cleaning water, are even more stringent.
