"Industries that must treat or pretreat their wastewater face varied challenges. Any given facility’s needs are best met by a total systems approach (TSA) — a fully integrated solution that includes all pieces of the puzzle instead of uncoordinated components and systems. The approach includes a collaborative evaluation up front to understand a facility’s requirements, apply proven designs and materials, and select innovative products that achieve the optimum water quality at the best life cycle cost."
