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

Abstract

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.

This paper will cover advanced primary treatment utilizing pile cloth media filtration versus conventional treatment. The concept and principles of carbon diversion and how the use of pile cloth media filtration allows WRRF's become more energy efficient and production of biogas. Also, the paper covers the ability to handle wet weather peak flow conditions by providing dual treatment capabilities.

Two Years Operating World's Largest Capacity Facility of Latest Generation Wet-weather Disk Filters

Abstract

The recently expanded and upgraded Tomahawk Creek WWTF continues JCW’s success eliminating wet-weather overflows and complying with new nutrient limits. After comprehensive evaluations of source control, equalization, conveyance, and treatment alternatives, JCW implemented an auxiliary treatment strategy with dual-purpose filters as the most resilient, sustainable, and cost-effective alternative. This strategy initially saved JCW $200M in construction costs compared to storage and equalization alternatives. Design collaboration with a construction manager at risk (CMAR) saved another $40M in construction costs through value engineering studies at the 60% design stage that optimized site usage and technologies for auxiliary treatment and biological nutrient removal. The renewed WWTF started operating dualpurpose pile cloth disk filters in 2021 for tertiary treatment of flows up to 216 ML/d (57 mgd) and auxiliary treatment of wet-weather flows up to 435 ML/d (115 mgd) for a total peak flow capacity of 651 ML/d (172 mgd).

Renewal of the Tomahawk Creek Wastewater Treatment Facility is a major milestone in Johnson County Wastewater's Integrated Plan to identify, assess, and prioritize infrastructure initiatives and investments. Among its innovations, the updated facility uses an auxiliary treatment strategy with dual-purpose pile cloth disk filters that polishes effluent and cost-effectively treats peak wet-weather flows up to 651 ML/d (172 mgd) for year-round benefits to local streamways.
