Process water recycling systems are designed to recycle water that is used in industrial processes. These systems typically involve the treatment of the used water to remove contaminants, followed by the reuse of the treated water in the industrial process. The main goal of process water recycling systems is to improve the quality of water utilized in the process, through high-recirculation rates, while reducing the amount of fresh water that is required, which can help to conserve water resources and reduce the costs associated with obtaining and treating fresh water.
Effective process water recycling systems play an important role in water conservation and resource management and represent the future of manufacturing. In most cases today, in an effort to reduce water consumption, the overflow rate of rinse tanks is reduced to the bare minimum resulting in variability in the quality of water in the rinse tank depending on factors such as production rate, chemical carryover, and tank volume. This variability directly impacts process quality and process control and can lead to surface staining, chemical cross-contamination, and other issues. Conversely, when recycling water, flow rates can be increased and matched to the requirements of the specific application resulting in high-quality, consistently pure rinse water.
The specific treatment methods used in a process water recycling system will depend on the type and concentration of contaminants present in the water. Common treatment techniques include filtration, absorption, ion exchange, and membrane technologies and it is important to work with a company with expertise in all of the available technologies so as to optimize for a given process.
