Cooling water bypass filtration
Open circulating cooling water systems may be optimized by bypass filtration, for which moving bed filtration is a most efficient tool. The MBF treats a small part of the warm water flow, returning from the production processes. The filtrate is returned to the cooling water circuit, while the continuously released wash water is discharged to the blow-down pit. Bypass filtration is typically handling 1 – 10% of the recirculating flow in order to be effective. ROI is typically in the range of 6 – 12 months.
Specific advantages
• Improved heat transfer because of cleaner heat exchangers;
• Removal of suspended solids;
• A shift of microbial activity from the cooling system to the moving bed filter;
• Lower maintenance requirements and reduction of product leakages
