The Filzaim (FZ-type) is composed of silica and clay and possesses an immobilized inorganic natural enzyme. This porous ceramic system is in fact a version of the FA type which already has an incumbent capacity to absorb oil and fats, but the FZ-type is further enhanced with even more cleaning capacity because of its high density of pores, air-letting ventilation, and increased surface dimensions (which allows it to retain more water). The result is an ideal environment for bacteria to inhabit the ceramic and to break down the oils and fats in the waste water. The FZ-type porous ceramic offers the important, cost-saving advantage of being able to be retro-fitted into an existing water treatment system without significant modifications. The basic system will require two tanks, one for digestion and another for absorbing the waste. However, by also installing an oil-water separation tank, the long-run, operating-costs will be reduced. The system is compact, easy, and provides spectacular results. oil separate tank   In the below diagram the first tank separates the water from the oil, the water is then caught and passed on to a second tank called the "fat-oil absorbent tank". fat oil absorbent tank   In this "fat-oil absorbent tank" (tank number 2) the separated water makes first contact with the FZ-type porous ceramic. The FZ-type porous ceramic goes to work by breaking down the oil through a biodegradation process. digestive tank   The last stage of the water treatment process (again see below diagram) is the digestive tank whereby the final oil and waste water is broken down into a sludge using a second FZ-type porous ceramic; in effect 90% of the oil is removed from the water at this stage. What rests is a 10% residue, of which can be easily disposed. Through this process waste removal costs are dramatically decreased.
