Zeosorb provides a safe and economical solution for the most varied filter tasks. This filter medium has proved itself the best in many areas, including the chemical industry, food and drink production, in the pharmaceutical industry and in sewage treatment. Due to its high through put and precise filtration clearance, Zeosorb is particularly economical.

Alternative to sand

Several differences set Zeosorb apart from regular sand and make it an excellent filter medium. Most sand particles have relatively smooth surfaces and no porosity. They trap particles by straining and bridging them. As the dirt layer increases, sand will typically remove particles down to approximately 30- to 40 microns.

Zeosorb, by comparison, has large, rough, angular surfaces with chambers and cavities running throughout each particle. This structure allows it to remove suspended particles by straining and bridging between the granules, but aim to capture particles on the rough surface and in the internal pore spaces. This gives Zeosorb the ability to remove particles as small as 3- to 5 microns, according to measurements taken with a scanning electron microscope. With its increased surface area, Zeosorb's dirt-loading capacity is significantly greater than silica sand.
