The horizontal sparkler type filters is the most versatile filtration system for solid liquid separation. It can also be used apart from filtration, with the help of filter aids for giving a sparkling effect to the liquids filtered. The filters are most suited for the filtration of products for the pharmaceutical, chemical, distillery, beverage, ink, oil and other allied industries. It is available in different output capacities with a variety of pumps to suit individual requirements.
The filters are made out of stainless steel in S.S. 304, 316 & 316 L qualities. The cartridge assembly consists of a number of disc type filter plates with perforated support screen, filter media and interlocking cups placed one on top of the other and supported at the bottom by a cartridge plate. The entire assembly is held together with the help of side tie rods which are of 'T' type construction for longer life. The filter together with the pump and interconnecting piping is mounted on a sturdy base clad with S.S. sheets and provided with castors for movability. The filter can also be supplied without pump, where external positive pressure is available.
The liquid to be filtered is passed into the vessel by means of the pump or other external means. The liquid then passes through the top of the filter plates from the holes provided at the side of the plate and onto the filter media. The liquid flows simultaneously and individually through all the member plates. Hence the output of the filter depends on the diameter and the number of plates. The filter media then retains the impurities in the liquid and the filtered liquid passes through the central channel to the outlet at the bottom. The filters are optionally available with steam jacket for filtration of difficult liquids that solidifies at lower temperatures. These types of filters are generally used for obtaining clear filtrate, but it can also be used to obtain the cake that is retained on the filter media, between the plates.
