Filtering Silicon, Heavy Metals & Gallium Arsenide

Oberlin Filter provides solutions to the word’s largest semiconductor and solar manufacturers wastewater issues. They produce wastewater contaminated with silicon fines, Gallium Arsenide and other heavy metals. Oberlin Filter provides filter systems that remove these substances to meet sewage discharge limits. The filtered water is extremely clean and can be recycled and reused within the plant. The effectiveness of the Oberlin Filter allows for a one step filtration process that delivers clean water and dry solids for many applications in these fields.

One of the world’s largest semiconductor manufacturer’s plants was producing such an enormous volume of wastewater that it was overburdening the sewer with silicon fines. We provided a filtration system that cleaned the water so it could be safely discharged into the sewers or be reused. The Oberlin Filter reduced the solids from >500 ppm to <1 ppm. The water clarity went from >1000 NTU to <1 NTU. We are now an integrated part of this manufacture’s semiconductor chip making process.

About us

Oberlin Filter Company is been guided by one principle: make filters that really work. Our excellent group of experienced engineers, salesmen, designers, welders, plumbers, electricians, servicemen, and laboratory technicians work with our customers to determine the best system for their application. We build it ourselves, help start it and provide support throughout its lifetime. There are Oberlin filters that have been operating continuously for over 40 years.

We are a family owned and operated business. Three generations of our family have worked hard to build filters and treatment systems that are dependable, reliable and get the job done. Our founder, Wayne Oberlin, started Oberlin Filter by making one filter at a time. His son, Tom Oberlin, developed and expanded our filtration technology making Oberlin Filter a global leader in liquid solid separation. This attention to detail and tenacity of spirit has enabled Oberlin Filter to grow into an international company that still calls Waukesha, WI home.

We are an engineering company. Our engineers are your project managers and are responsible to you for the filter’s satisfactory operation. They supervise your order from initial design stage, through production and startup. They are always available for support.

We have a global presence. We have manufacturing plants in England and Germany that provide sales, design, manufacturing and service support throughout Europe. We have service agents placed throughout the world. There are Oberlin pressure filters operating in over 30 countries throughout the world.

We are active in four major markets: Metal Working Fluids for grinding and machining, Food applications primarily in hot frying oil and specialty oils, Chemical Separations and Industrial Water Treatment. Industrial water treatment covers a wide range of applications with almost all of them unique to the client. We enjoy strong working relationships with GE and their many divisions, Veoliawater, DuPont, and a major semi-conductor manufacturer in their silicon wafer cutting processes.
