Koch PURON® Modules

PURON MBR
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.

PURON HF (HIGH FLOW)
An evolution of the PURON MBR modules, the PURON HF series is ideal for tertiary applications including RO pretreatment and surface water treatment. With system recoveries of more than 95%, the PURON HF produces consistent, high-quality effluent that meets or exceeds most regulatory requirements.

This hollow-fiber product is a high throughput, compact wastewater solution with a low lifecycle cost. It features 44% more membrane area than the PURON MBR module within the same dimensions and supported fibers that virtually eliminate breakage.

PURON MP
PURON MP pressurized hollow-fiber ultrafiltration provide a cost-effective solution for a variety of water and wastewater treatment applications. The system’s high flux and solids tolerance properties eliminate the need for costly pretreatment and chemical cleans while producing high-quality effluent and meeting stringent regulatory targets, including drinking water LT2 specifications. Polyester reinforced PVDF membranes and a unique single-potting design help to avoid downtime. Performance, simplified operation, reduced maintenance and compact footprint add up to one cost-effective filtration solution.

PULSION MBR
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.
