PURON MBR and PULSION MBR Modules
The single-header ultrafiltration PURON membrane bioreactor changed industrial and municipal wastewater treatment. This patented module features reinforced PVDF hollow fibers that are fixed only at the bottom, virtually eliminating the clogging buildup of hair, fibrous materials and sludge solids. Solids and particulates, including bacteria, remain on the outside, while permeate is drawn through the membrane to the inside of the fibers. The aeration nozzle is centered in the fiber bundle to scour the entire fiber length, minimizing power consumption.
The next generation of PURON MBR, PULSION MBR modules offer up to 40% aeration energy reduction and 25% footprint reduction. This innovation pulses a large bubble through a chambered fiber bundle, creating a piston-like pumping action that results in lower air and aeration energy requirements than traditional scouring methods. Improved recirculation of mixed liquor in the membrane module boosts achievable fluxes and overall performance.
Optimized design and layout has reduced tank sizing while eliminating the need for air cycle valves. A minimized continuous air flow applied to the membranes has decreased the size of air delivery equipment by 50%, also reducing operation costs.
PURON® PLUS MBR systems, featuring our submerged PULSION® MBR modules, are pre-engineered membrane bioreactor (MBR) package plants. With capacities ranging up to 250,000 GPD, they are designed for both municipal and industrial wastewater applications, including food, dairy, beverage, leachate and produced water.
These skid-mounted systems offer a complete and cost-effective design. The virtually unbreakable high-performance PURON membrane provides consistent high-quality effluent. Coupled with a comprehensive biological system, the PURON PLUS MBR system can reduce BOD and nitrogen concentrations down to 5 and 10 mg/L respectively.
