Biomass-Fired Power Plant, CA 2017-02-16T16:30:18+00:00

Project Description

Biomass-Fired Power Plant, California

StormwateRx LLC designed and supplied stormwater treatment BMPs for the two main outfalls from a 25 megawatt biomass-fired power plant located on a 50-acre industrial site in California. The treatment system, deemed best available control technology by the plant’s attorney, removes TSS, iron, aluminum, zinc and other metals from the facility runoff in compliance with the Califorina Industrial General Permit.

TARGETED POLLUTANTS total suspended solids (TSS), specific conductance, oil and grease, biochemical oxygen demand (BOD), chemical oxygen demand (COD), copper, iron, lead, zinc, aluminum, arsenic, and chromium.

APPLIED PRODUCTS

BACKGROUND

StormwateRx LLC designed and supplied stormwater treatment BMPs for two main outfalls of a 25 megawatt biomass-fired power plant located on a 50-acre industrial site in California. The power plant’s fuel consists of approximately 240,000 tons annually of biomass waste made up of principally urban wood waste, in-forest brush and clearing, agricultural byproducts, and other wood related products. The facility discharges stormwater to the Sacramento River, San Joaquin River, and the Sacramento-San Joaquin River Delta in central California.

The plant was retrofit with a StormwateRx LLC Clara® 90CP plug flow separator system that doubled as a pump station to filtration and an Aquip® 210SBI basic stormwater filtration system to reduce stormwater pollutants from the main plant outfall.  The systems were retrofit to an existing outfall in a treatment train configuration. A second fully passive Aquip 210C enhanced stormwater filtration system designed in a vault configuration was installed at a secondary outfall.  In conjunction with other source control BMPs, the StormwateRx treatment system reduces discharges of stormwater pollutants including total suspended solids (TSS),oil and grease, chemical oxygen demand (COD), copper, iron, lead, zinc, aluminum, arsenic, and chromium.

PROJECT RESULTS:

The stormwater treatment systems were retrofit to two existing outfalls. In conjunction with other source control BMPs, the StormwateRx treatment system reduces discharges of stormwater pollutants in compliance with the California Industrial General Permit.
