Traditionally, water recovery principles have been pretty restrictive. Once the rule was that any water that hit the floor in a processing facility would no longer be suitable for any further use. Regulators in certain parts of the country are starting to change their tune, however. With reservoirs out West still at critically low levels in many areas, water reuse is an important tool for stretching this valuable resource.
Water recovery technology exists to produce reusable water within processing facilities. Dairy plants, in particular, produce a lot of water that may be suitable for reuse with the proper equipment on-hand. Evaporator condensate and RO permeate are two such sources that can potentially be reused. Potential uses for recovered water include cooling tower makeup, cleaning/sanitation, boiler makeup, process water and production water.
- Purifying process wastewater to create a clean water source that meets the requirements of the reuse application
- Handling the concentrated solids stream that results from the purification process to enable:
- safe discharge/disposal, or best case,
- creating a product of added value to the customer.
