Domestic Advanced Primary Wastewater Treatment Utilizing Pile Coth Media Filtration for Operational Savings and Increased Biogas Production and Wet Weather Treatment

The use of pile cloth media filtration (PCMF) is becoming a new solution to allow treatment facilities to achieve advanced treatment without chemical addition in a dramatically reduced footprint in comparison to conventional primary sedimentation. PCMF brings a high-quality effluent quality which allows the technology to be used, also for the wet weather treatment in dual treatment applications. The study and full-scale installation data has confirmed that PCMF can achieve consistently >80% TSS and >50% BOD/COD removal in primary applications. The has been much testing in documenting the benefits of advanced primary treatment with PCMF. This includes the reduction in aeration requirement for the biological treatment processes and/or more biological treatment capacity without additional basins/tankage. Other benefits such as more primary solids for anaerobic digestion and increased biogas and energy production within the wastewater facility. In wet weather applications, the technology is producing effluent quality that achieves EPA secondary effluent standards or better.
