Wood Application: Turnkey Solution

FRC provided a turnkey solution for a global manufacturer of residential and architectural doors.  One of their production facilities with wastewater production in excess of 790,000 gpd had to bring their discharge into compliance.  FRC brought in a pilot DAF System for proof of concept to confirm removal of the Total Suspended Solids (TSS) and a Belt Press as an additional cost saving process for dewatering of sludge. After a successful two-week trial, the client went forward with a full FRC solution including design, manufacture, and complete electrical and mechanical installation.
