Wigen - Gravity Media Filters
Wigen designs and builds custom gravity media filters for a wide variety of industrial and municipal applications. As the name implies, gravity is used as the motive for a fluid stream to pass through a bed of granular media through which physical and/or chemical removal of impurities is achieved. Gravity filters are ideal for treating larger volumes than pressure filters can economically handle. Our systems are manufactured in-house, to ensure quality control, while keeping the capital cost down.
