Owners of NEOSEP MBR systems benefit from Kruger’s experience and record in designing robust, reliable, and user friendly wastewater treatment process solutions, as well as Veolia’s worldwide experience in MBR WWTP design and operation. The NEOSEP MBR process enhances and simplifies conventional activated sludge processes by eliminating final clarifiers and filters. The membrane barrier ensures stable operation, consistently producing a high quality effluent in a small footprint. NEOSEP MBR systems are designed to accomplish BOD and TSS removal, nitrification, denitrification, and enhanced biological and/or chemical phosphorus removal.

A NEOSEP MBR system typically consists of separate aeration tanks followed by membrane tanks containing submerged membrane modules. The process incorporates screens; activated sludge bioreactors; aeration, mixing, and pumping equipment. The NEOSEP MBR process is controlled by a PLC based control and SCADA system. The membrane elements separate the mixed liquor solids from the treated effluent which is drawn through the membrane by either gravity or pumps. The permeability of the elements is maintained through air scouring of the membrane surface, a membrane relaxation phase and a periodic in-situ chemical cleaning. Excess mixed liquor solids are wasted directly from the aeration tanks.

Sample Streams From Operating NEOSEP MBR System

The samples shown are of typical screened influent with a total suspended solids (TSS) concentration of 220 mg/L and mixed liquor with a TSS concentration of 12,000 mg/L. The NEOSEP membrane removes all of the solids with typical effluent TSS in the non-detect range and turbidity of <0.05 NTU.

NEOSEP® MBR Package System

The NEOSEP Package System is a self-contained modular wastewater treatment plant ideal for nominal operating flows between 25,000 and 75,000 gallons per day (GPD). Each unit is pre-engineered, skid mounted and factory tested, allowing for savings on installation time and cost.

The MBR process is robust and requires minimal operator attention. The process is designed in an MLE configuration with submerged flat sheet membranes handling the liquid solid separation step. The membranes allow for a compact footprint and a superior effluent; CBOD5 < 5 mg/L, TSS < 1 mg/L, TN < 10 mg/L and Turbidity < 0.1 NTU. Phosphorus removal can be accomplished with the addition of coagulant.
