Zhangjiagang to Use Koch Membrane Systems PURON® MBR Modules

Posted: Friday 23rd September 2011

Koch Membrane Systems GmbH (KMS) has been selected by Pacific Water Treatment Engineering Co., Ltd. to provide PURON® membrane modules for a new city wastewater treatment facility in Zhangjiagang, China.

The system will help to meet stringent local discharge standards in Zhangjiagang, in Jiangsu province, about 150 km northwest of Shanghai.

Due to the facility’s close proximity to residential areas, limited space, and high property costs, a membrane bioreactor (MBR) was the technology of choice for Zhangjiagang JinGang Sewage Treatment, a state-owned entity that operates all municipal wastewater treatment plants for this city.

“After an extensive evaluation of the major membrane systems available on the market, we selected PURON submerged MBR modules because of their energy efficient design, the smallest footprint requirements as well as KMS’ engineering support during the entire project phase,” says George Shen, chairman of the board at Pacific Water Treatment Engineering Co., Ltd., a leading engineering company in China selected by the municipality to design and construct the MBR system. “We are also impressed with the strong, braided fibre, which reduces the risk of fibre breakage.”

The system is designed to handle an annual average flow of 25,000 m3/d, with peaks of up to 36,000 m3/d. Start-up is scheduled for early 2012.

PURON PSH 1500 modules are specifically designed for large-scale MBR projects. Features such as an optimized permeate extraction manifold and air supply lines reduce the number of piping connections during installation.

China’s MBR market has been growing rapidly over the last five years with several installations larger than 10,000 m3/d. KMS has a large base of industrial hollow fibre references in China, ranging from surface water treatment to wastewater recovery in refineries and power plants. The Zhangjiagang City project will be the first large-scale municipal MBR reference for KMS in the country.


Reverse Osmosis Membranes Will Supply 8 MGD Water Treatment Plant

Wilmington, Mass. – July 11, 2011 - Koch Membrane Systems, Inc. (KMS), a world-class developer and manufacturer of innovative membranes and membrane filtration systems, has been selected to provide its Fluid Systems® TFC® reverse osmosis (RO) membranes for the municipal water treatment plant at the Town of Davie, Fla.

As part of a project to upgrade and expand the capacity of the existing facility, the KMS RO elements will be installed in four trains with a 2.0 MGD capacity each, running at 80 percent recovery. These RO trains, along with three cartridge filter vessels and one clean-in-place system, will be designed and fabricated by Aerex Industries, based in Fort Pierce, Fla. The total plant capacity will be 8 MGD, serving a population of 90,000.

“Aerex Industries selected KMS as the membrane element supplier for the Town of Davie project based on our confidence in their ability to provide the correct membrane product, support and warranty to ensure a trouble free start-up and satisfied customer throughout the life of the membrane,” said Montroe Deon Hopkins, Project Manager/Project Engineer at Aerex. “KMS has demonstrated that they share our corporate philosophy that customer satisfaction is of the utmost importance.”

RO will be incorporated into the Town of Davie water treatment plant to lower the Total Dissolved Solids in the well water that supplies the area’s drinking water. RO is the most energy efficient method of removing dissolved salts and other water borne contaminants from water to meet drinking water standards. The treatment of brackish water for municipal water supplies is one of the most common RO applications.

Delivery of the KMS membranes is expected to be in early 2013 with commissioning of the plant scheduled for June 2013.

Koch Membrane Systems is where modern reverse osmosis RO membrane technology for desalination and water purification got its start. For more than thirty years, the highly innovative FLUID SYSTEMS® brand has been serving residential, commercial, and industrial water filtration and purification markets with state-of-the-art membrane elements.

KMS’ highly skilled and experienced engineers can help tackle the most complex water and wastewater challenges, from membrane selection and system design to piloting, start-up, and post-commissioning technical support.


System Offers MBR Technology in a Skid-mounted Packaged Plant

Wilmington, Mass. – July 6, 2011 - Koch Membrane Systems, Inc. (KMS), a world-class developer and manufacturer of innovative membranes and membrane filtration systems, announces the first North American installation of a PURON™ PLUS packaged membrane bioreactor (MBR) wastewater treatment system.

The new PURON PLUS MBR system will serve an apartment complex in Massachusetts and is designed to meet stringent surface discharge limits for biochemical oxygen demand, total suspended solids, and total nitrogen. The packaged system consists of two membrane trains each containing one PURON membrane module, as well as ancillary equipment, controls, engineering and technical services, and is designed for an average flow of 24,000 gpd and peak flow of 32,000 gpd.

“Environmental concerns combined with increasingly stringent wastewater discharge requirements are escalating the importance of wastewater treatment, said KMS Director of Marketing and Communications Peter Bouchard. “Commercial and residential development is contributing to the need for prudent water management and creative technological solutions to treat wastewater from municipal and industrial effluents.”

MBR systems are well suited to both industrial and municipal wastewater treatment. MBR technology combines biological wastewater treatment and membrane filtration into one unit process, producing a consistently high quality effluent in an extremely compact footprint.

KMS’ PURON PLUS MBR packaged system offers state-of-the-art MBR technology in a skid-mounted packaged plant that provides customers with a full scope of supply, from prescreening and biological treatment through to the final membrane clarification step. The pre-engineered MBR plants are available with capacities ranging from 15,000 to 200,000 GPD and offer a reduced footprint, flexible layout, and a design optimized to meet most environmental discharge regulations. KMS supports each system with process and design expertise allowing for a fast installation and startup.

PURON membrane filtration modules are at the heart of the PURON MBR system. With improved membrane density and reduced air scour requirements, PURON modules are energy efficient, provide significantly lower lifecycle costs than alternatives, and are compatible with other commercially-available systems.
