Many industrial companies require different types of process and service water for their production and manufacturing processes. These include, for example, water for cooling purposes, washing and flushing water, seal water for rotary seals, service water to prepare chemical solutions etc.

Expert pre-filtration prevents subsequent expense:

Improved service lives of fine filters and membranes downstream
Lower maintenance costs as a result of longer service intervals
Lower energy consumption
Increased process reliability
Reduced operating costs
Guaranteed quality
