Delta Treatment Systems’ ECOPOD-D Solves Wastewater Treatment Challenges

Delta Treatment Systems ECOPOD-D Advanced Wastewater Treatment Units offer treatment capacities from 1,500 to 100,000 gpd in pre-engineered treatment plants for commercial or decentralized wastewater treatment needs. The ECOPOD-D technology has been tested under Standard 245 of ANSI/NSF International and exceeds Class 1 requirements with an average effluent quality of 6 mg/L BOD5 and 8 mg/L TSS, according to the manufacturer.

The ECOPOD-D disposes of wastewater quietly, efficiently and with no odor. It has no inner tank filters, screen or diffusers to service.

Its total nitrogen-removal capabilities and simple operation make it ideal for small cities, rural communities, schools, high-strength commercial facilities, and retail and office developments.

Up to the challenge

The small town of Section, Alabama, is in the northeast corner of the state and has a population of 770. Its 30,000 gpd system was designed to treat the domestic waste produced by both residential and commercial entities for the town.

The project was designed for a two-phase installation. The first phase was designed to treat 30,000 gpd domestic waste at a strength of 300 mg/L of both BOD and TSS. It is also designed to handle an average daily flow fluctuation over a range of 50 to 100 percent.  

To ensure efficient, optimum system operation, the ECOPOD units were shipped directly to the site complete and ready for installation, including all the component equipment. The units were installed in poured-in-place concrete tanks equipped with aluminum hatches. 

A flow equalization tank was installed before the ECOPOD treatment reactor tanks at a volume of 14,208 gallons. The purpose of the flow equalization system is to store the wastewater and evenly dose it to the ECOPOD treatment system throughout a 24-hour period, as the biology is most efficient when being fed consistently throughout the day. The flow equalization tank includes duplex pumps to ensure flow surges do not reduce the efficiency of the treatment system. 

A 19,190-gallon primary tank precedes the flow equalization tank. The effluent also passes through a UV system for disinfection of fecal coliform to concentrations below permit levels. A drip disposal system, also supplied by Delta Treatment, includes an effluent pump chamber, headworks, tubing, controls, and all necessary valves and fittings. A concrete building was erected on site by the project contractor to house electrical controls and equipment.
