Fluid Technology-Our Products

Koch Membrane Systems

Koch Membrane Systems has been fulfilling the advanced membrane filtration needs of thousands of customer worldwide, for over 30 years.

Koch’s ability to supply a vast variety of membrane products in spiral, tubular, hollow fiber, and flat sheet configurations to meet virtually every performance requirement has impressed everyone.

Reverse Osmosis Membranes Fluid Systems was an early pioneer in reverse osmosis, and its development work in the mid-1960s contributed significantly to the commercial acceptance of the technology. Today, Fluid Systems holds numerous patents and is a recognized leader in reverse osmosis products worldwide. The RO membranes range from 2” to 18” diameter of tube, 30” to 60” in length.
Koch Ultrafiltration Membranes
Spiral Membranes Koch’s attention to spiral design details provides significant capital and operating cost savings. The increased flux and long-term stability created by our charged membranes result in greater and more stable productivity, requiring fewer modules and less frequent cleanings. Specialised feedspacer development, higher packing density and enhanced bypass control by Koch’s patented flanged module, result in dramatically reduced flow requirement, further reducing your capital and operating cost through energy savings. When retrofitted in competitors’ systems, your processes benefit from enhanced performance, extended life, dependability and increased operating efficiency. Benefits: Lowest capital and operaitng costs Highest Productivity Minimal cleaning frequency Greatest long-term stability Greater efficiency in performance
Tubular Membranes Koch’s patented tubular modules are more durable, have improved long-term flux stability and provide greater productivity than existing conventional tubular modules. Advances in manufacturing techniques enable us to offer a membrane film cast support tube while still maintaining the ruggedness, reliability and membrane life critical to trouble-free, long-term operation. Benefits: Lower fouling with less frequent cleaning Stronger construction for longer life critical to trouble-free, long-term operation More reliable and less susceptible to leaking Lower installation costs 1" tubes are mechanically cleanable
Hollow Fiber Membranes Koch’s patented hollow fiber modules allow a high membrane surface area to be compressed in a minimal space. The self-supporting membrane can be backflushed to maximize the efficiency of the crossfllow filtration process and maintain constant throughout. This operating feature, combined with chemical stability, ensures reliability and long life expectancy . Benefits: Crossflow filtration minimizes fouling and paint build-up Backflushable cleaning maximizes efficiency High durability for longer life Lower capital cost
Koch formulates its KOCHKLEEN membrane cleaners specifically to Remove the organic and inorganic foulants found in industrial wastewater applications. The unique line of acid, alkaline, surfactant blend and oxidizer membrane cleaners thoroughly clean most membrane types. Whether your system includes tubular, spiral, hollow-fiber configurations used for microfiltration, ultrafiltration, nanofiltration or reverse osmosis, we supply the cleaning solution for you.
