ECOPOD Series waste water disposal installation

The ECOPOD-Series is the clear choice for an on-site waste water disposal system where nitrogen reduction is required. It was tested under NSF/ANSI 40 and 245 with an average nitrogen reduction of greater than 50% and met and exceeded Class 1 requirements with an average effluent quality of 9 mg/L BOD5 and 8 mg/L TSS.

The ECOPOD Advanced Waste Water Treatment System is Delta’s patented FFBR (fixed film bioreactor) system. Five models are available to accommodate daily flows ranging from 500 to 1,500 GPD, with customizable options available for commercial applications. The ECOPOD is ideal for individual residential installations, cluster designs, and small-to-medium commercial waste water treatment applications, and intermittent use applications.

Waste water enters a pretreatment tank where debris and settleable solids settle to the bottom and are decomposed by anaerobic bacteria. The effluent enters the ECOPOD from the primary tank where it is introduced into an oxygen rich environment. Air is provided by an external air compressor. Biomass develops which is capable of digesting biodegradable waste into carbon dioxide and water.

The ECOPOD houses an engineered plastic media specifically designed to treat domestic waste water. It is submerged in a tank of liquid, which works as a dilution zone. There are no moving mechanical parts or filters in the ECOPOD. In this system, conditions are favorable only to attached growth bacteria, meaning common disadvantages such as rising sludge, floating sludge or washouts are eliminated. In addition to CBOD and TSS reduction, ammonia nitrogen is reduced as nitrification of the ammonia and denitrification of nitrates occurs within the single reactor tank. There are no moving mechanical parts, inner tank filters, screens or diffusers to service in the ECOPOD. And because it operates as a true attached growth system, there is no mixed liquor. A 60%+ removal rate of total nitrogen is common without any type of recirculation or cycling of the blower. The result of this process is a clear discharge with no offensive odors that meets or exceeds state water quality standards.
