Submerged Membrane Modules provide wastewater treatment.

Press Release Summary:




PURON® Modules are intended for membrane bioreactor treatment of municipal and industrial wastewater. Hollow fiber membranes, 2 mm in diameter, with pore size of less than 0.1 µm, are bundled in single header at lower end. Each hollow fiber membrane filter is sealed at upper end and allowed to float freely. With water flowing from outside to inside of filters, solids and particulates are blocked by membrane and remain on outside, while permeate is withdrawn from inside of fibers.

Koch Membrane Systems Offers Puron® Submerged Membrane Modules for Municipal and Industrial Wastewater Treatment



A Cost Effective and Energy Efficient Solution for Membrane Bioreactors (MBR)

Wilmington, MA - Koch Membrane Systems, Inc. (KMS), a world-class developer and manufacturer of innovative membrane filtration systems, offers PURON® submerged membrane modules for membrane bioreactor (MBR) treatment of municipal and industrial wastewater. These technologically advanced membrane modules significantly improve water quality, while utilizing less space than conventional alternatives.

The extremely effective PURON aeration system from KMS ensures optimal solids management, high flow rate and reliable operation, while using up to 50 percent less energy than other MBR systems. Membrane bioreactors with submerged membrane modules are increasingly used for some of the toughest wastewater treatment applications, including sewage treatment for municipalities, and treatment of wastewater for malt beverage, textile, food, paper and chemicals industries. By using MBR to recycle process water, industrial companies cut wastewater disposal costs and reduce consumption of fresh water.

A proprietary feature of the PURON module from KMS is the air nozzle, which discharges air from the center of each fiber bundle at the base. The combination of rising air bubbles, the resulting hydraulic cross flow and the seaweed-like movement of the membrane filters comprise an energy efficient process that ensures that even sludge, hair and other fibrous components are dislodged from the membranes and moved safely out of the system.

The patented design of the PURON membrane module provides reliable removal of filtered substances. Hollow fiber membranes, 2 mm in diameter, with a pore size of less than 0.1 micrometers (μm), are bundled in a single header at their lower end. Each individual hollow fiber membrane filter is sealed at the upper end and allowed to float freely. The membrane is coated on a braid increasing the mechanical strength of each fiber to ensure that the fibers will not break or delaminate during operation. Water flows from the outside to the inside of the filters. Solids and particulates, including bacteria, are blocked by the membrane and remain on the outside, while permeate is withdrawn from the inside of the fibers.
