Sanitaire ICEAS® Advanced SBR Technology by Xylem

Sanitaire has provided the wastewater treatment industry with innovative and cost-effective treatment technologies for over 35 years. This tradition continues with the Sanitaire Intermittent Cycle Extended Aeration (ICEAS) process, which is an advance sequencing batch reactor (SBR) technology for municipal and industrial wastewater treatment.

The conventional SBR, a variant of the activated sludge process, operates on the fill and draw principle. Fill, react, settle, decant and idle phases occur sequentially on a cyclic basis. In the conventional SBR configuration, flow is diverted from the basin during settling and decanting and requires two or more basins or an influent equalization tank to receive flow when settling and decanting. Sanitaire can provide a conventional SBR but recommends the superior flexibility of the ICEAS design, which does not require any flow diversion.

The ICEAS Process
The advanced Sanitaire ICEAS process is a fully automated and simple to operate biological treatment system that:

• Operates as a time-based control system allowing continuous inflow of wastewater during all phases of the cycle.
• Responds to flow and load variations.
• Can achieve processes of biological oxidation, nitrification, denitrification, phosphorus removal and liquid/solids separation continuously in a single basin.
• Easily expands and produces a high quality effluent.
• Provides two treatment zones (pre-react and main-react) separated by a non-hydrostatic baffle wall.
• Utilizes the pre-react zone as a biological selector for enhancing the growth of desirable organisms.
• Offers flexibility for meeting specific application needs with custom engineered process cycles.
