Our Technology

The SEQUOX® Process

The SEQUOX® Process with our innovative DO2ptimizerTM control strategy offers optimal energy efficiencies. It has more turn down for under loaded plants than ever before. The control philosophy allows the plant to mimic the actual organic loading coming to it.

Cost Effective Nitrogen Removal

The patented SEQUOX® Nitrogen Removal Process is the latest innovation for biological nitrogen removal from wastewater. Even if nitrogen removal is not the primary objective, the SEQUOX® process results in sufficient process improvements and energy savings to make it cost effective.

Superior Effluent Quality

SEQUOX® offers the benefits of sequencing aeration with the reliability of continuous clarification, resulting in consistently superior effluent quality with total nitrogen levels of 3 mg/L. With the inclusion of the Bio-P process, phosphorus levels of 1 mg/L or less are possible. To achieve better solids settling, SEQUOX® incorporates a selector tank to provide a preconditioning of raw wastewater that inhibits filamentous growth. The process is energy efficient and has a small footprint, lowering capital costs.

Innovative High Performance Clarifier

The patented, low-maintenance, operator friendly ClarAtor® provides clarification to the Aero-Mod system. It features no moving parts below the water, a uniform distribution and collection of the flow, and the unique ability to regulate the effluent flow rate. Its unique flow regulation system even provides in-basin surge storage.
