Product Introduction
Sand filters are utilized to remove suspended particles until 50 µ diameters in water. Active carbon filters are usually used to remove organic materials and extract free chlorine from water in order to improve it for feeding system. These kinds of filters not only cause to remove taste, color, and odor from water but also protect unites and devices, which work with feed water, against the likely damage of organic deposits oxidation. Carbon filters are very useful devices to treat water because of being multi-purpose and not using additional harmful materials.
The different kinds of active carbon filters have different chemical and physical characteristics so the choice of appropriate filter for particular application is very important. According to the deposit concentration in water, these filters will be saturated after a while so they need back washing.
For back washing, three different mechanisms include manual, semiautomatic and automatic can be used. The revival time in active carbon is one to six months. These filters need to be washed by low-pressure steam about 25 minutes after back washing. In case of not being used for a log time, they should be washed by chlorinated water. These filters are designed at operation pressure between 6 and 10 bar.
Their main body is covered with zinc-rich and epoxy after cleaning and sandblast. The exterior surface of the filter is covered with a stainless layer and two oil painting layers. Each system is equipped by up and down inspection valves, manometer and, air discharge valve. Depending on feed water and the quality required, filter bed is filled with multilayer granulated anthracite silica stone.
