This is a Standard Operating Procedures document for the Microfiltration system at the Torrance Refinery Water Recycling Plant, involving the City of Torrance or relevant water authority in California. The document outlines operational protocols and procedures for managing the six-unit microfiltration system that was originally constructed in 1999 with a designed capacity of 3.73 MGD (518 gpm per unit). The SOP establishes guidelines for equipment operation, maintenance procedures, monitoring protocols, and performance standards necessary to support the feasibility study aimed at identifying replacement needs, increasing water production capacity, and evaluating the potential integration of West Basin's potable ultrafiltration system into the facility.

The SOP provides the technical foundation and operational framework that will inform the feasibility study's recommendations regarding system replacement, capacity expansion, and equipment relocation or installation. The procedures document establishes baseline operational parameters and identifies current system limitations and deterioration issues that have reduced the facility's water production capacity from its original design specifications, thereby providing critical baseline information for consultants conducting the feasibility assessment.
