​Evoqua Water Technologies has been selected, in concert with its sales partner, MISCOwater, to provide clarifier upgrades for the Southeast Water Pollution Control Plant (SWPCP) in San Francisco, California.

The San Francisco Public Utilities Commission (SFPUC) was looking to replace equipment at the SWPCP that had reached the end of its useful life, while also upgrading to the most advanced clarifier technologies.

The old equipment had been initially installed more than 30 years ago.

Evoqua’s Municipal Products and Services division will replace eight 120-ft. clarifier tanks with stainless steel secondary clarifiers featuring the advanced Tow-Bro Hydraulic Sludge Removal System and FEDWA Baffle System, both part of the Envirex product family.

FEDWA stands for Flocculating Energy Dissipation Well Arrangement.

This energy dissipating system reduces flow velocities and improves flocculation, or the clumping together of fine particles, for more efficient solids settling and increased treatment capacity.

The Tow-Bro System quickly and effectively removes settled solids with a hydraulic unitube header.

Evoqua has more than 100 years of experience with high performance clarifier technologies through its Envirex family of products.
