California Composting Wastewater
Supporting NPDES compliance at a compost site in California
This county-owned and operated composting operation was in violation of the Compost General Order. Clear Water, in conjunction with Geosyntec, designed a treatment system for wastewater (i.e., stormwater from the composting operation) at the site. Upon installation of the CESF treatment system with bag filtration, adsorptive media, and UV filtration, analytical testing proved that concentrations could be reduced below NPDES effluent limits. This is particularly great not only for the receiving water, Pila Creek, but also the Pacific Ocean. CWS continues to work with the County to address challenges associated with treatment of recently higher-strength wastewater.
Gallons treatedThe CS-20 control system is a modular, turnkey solution for automated water treatment operations housed in a 20’ CONEX box.
The CS-20 contains PLC-based controls, pump motor contactors and/or VFDs, chemical dosing systems for flocculants and pH, as well as water quality monitoring components and fail-safe valving to ensure compliance. This system houses multiple chemical storage tanks with containment to accommodate large volumes or several types of treatment chemistry in a climate-controlled environment.
Features Include:
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.
