Materials Recovery Santa Rosa
Equipment retrofits and upgrades for a large materials recovery facility
This materials recovery facility in Santa Rosa, California, encompasses 4.5 exposed acres. The site entered ERA level 2 for a one-year reporting period for TSS, aluminum, and iron, and entered ERA level 1 the following year for COD. Clear Water assisted the facility with retrofitting their existing stormwater treatment system to include a 4-pod sand filter, GAC media vessels, settling tanks for retention time, chemical dosing equipment, and an advanced control unit for automation capabilities. Since the retrofit, the site has reduced all pollutant loads below NAL values, achieving baseline status for all pollutants.
The upgraded system has treated and discharged more than 21 million gallons of stormwater since the upgrades.
Treating water at MRF sites offers challenges in filtering out trash captured by incoming stormwater, which can clog pumps and disrupt treatment. Clear Water worked with the client to reduce incoming trash and debris and utilized pumps capable of cutting through debris to help keep systems operational under adverse conditions.
Gallons treatedThe M5 is an all-inclusive treatment control unit, combining chemical injection, monitoring, and pump controls into one treatment controller.
Similar to the M3, the M5 uses a programmable logic controller (PLC) to monitor for pH, turbidity, and flow. The M5 also includes chemical metering pumps to automatically dose incoming water for a variety of contaminants.
The M5 has the capability to regulate pumps, monitor tank levels, and provide automated treatment operations with remote controls and automated data logging, lending itself to a range of applications across industries.
Clear Water Services offers many adsorptive (and ion-exchange) mixed media filtration options and equipment to remove just about any contaminant from water or air. Our adsorptive multi-media filtration options treat water for heavy metals, hydrocarbons, VOCs, PFAS, PCBs, nutrients, microbes, pesticides/herbicides, and others.
Our team of experts can evaluate historical water characteristics, site constraints, and performance goals, and run bench/pilot tests to determine the best media for the job. Alternatively, we can simply supply the media and equipment per specification. Our equipment options include both gravity drain (passive) and pressurized (active) options, that can act as stand-alone treatment or as a final polishing step based on the application.
