As industrial application become more demanding and more new areas of production processes are subjected to filtration and separation, there is a growing need for suppliers to have on hand highly knowledgeable engineers to analyze and solve problems. With the installation and separation equipment being a major capital expense, it is right to look up to suppliers of these products for service and support and to help come up with effective solutions to filtration and separation problems. Efficiency of use within the manufacturing processes is of prime importance. Filtration and separation equipment is used mainly in the following areas: from textile to pulp and paper industry, from chemical to food processing, from pharmaceutical to steel industry, electronics, artificial snow-makers, surface treatment, air and gas conditioning. A filter is basically a device for separating one substance from another, hence, filtration is basically a process of separation.

The various methods and processes of filtration and/or separation fell broadly into 4 categories: 1) solids/gas separation; 2) solids/liquids separation; 3) liquids/liquids separation; 4) solids/solids separation. Solids/liquids separation is an obvious field for mechanical filtration as such. In the processing industry in general, a well-designed filtration system must remove the contaminants within specified limits and must continue to maintain the quantity of filtered solution over the service life of the filter. Certain type of filters are more or less standard choice for certain applications but in other cases there are several possible alternatives to consider offering comparable performance. The main questions to be answered in fact are: what do you want to do and the efficiency and cost-effectiveness of the possible solutions. The perfect filter would have no pressure drop, hold an unlimited amount of dirt, be small enough to fit anywhere in a system, have high capture efficiency and cost nothing. Obviously this combination cannot exist and the pursuit of the perfect compromise has always been the challenge for filters manufacturers.

TECSI S.r.l. provide custom integrated water, waste water and process water filtration/separation solutions for industry offering industrial filters for solid/liquid separation in batch and continuous production. Industrial filters separate solid particles suspended in liquids through the use of filtering element called cartridges and are designed to meet a wide variety of applications. The range include: INDUSTRIAL STATIC LINE filters and SELF CLEANING filters, able to meet all your industrial water treatment needs, such as cooling water filters, sewage water filters, washing machines water filters, preliminary washing fruits water filters, pasteurizing fluid filters, well water filters, stream water filters, backwater filters, spray nozzle protection, industrial water filters, aerotextile plant water filters, artificial ponds water filters and more. Not all solid/liquid separator systems are alike: carbon and sand filters require regular maintenance that can result in downtime and higher labor costs.

SELF CLEANING filter is a valid alternative solution for cleaning of contaminated water and preventing unscheduled downtimes for maintenance and cleaning. Self cleaning is triggered by a pressure differential and is accomplished in a few seconds without interrupting the flow. It is possible to install three types of cartridges and scrapers: micro-stirred cartridge with tangent scraper blades; punched hole cartridges with tangent blades or PTFE; “V” bars cartridges with tangent blades or PTFE. Filters are available in SST (304L or 316), aluminum and plastic construction and are proven capable of 50 to 1500 micron performance, filtering particles as large as 1.5 to 0.005 mm, depending on the type of cartridge used and operate continuously (no fluctuations) at the steady pressure loss of only 0.2/0.3 bar.

They provide the very important efficiencies of contamination control but also have the capacity to give reasonable life for the customer. Of course, even the best filters have a limited lifespan. Therefore it is of extreme importance changing them according to the manufacturer’ s recommendations or more often if you are working in particularly dirty conditions. Letting them go too long renders them useless at best, harmful at worst! You can reliably turn to TECSI for which the important thing is designing a filter so there is value, where value doesn’ t mean cheap. Yes, you can probably save some money by ordering inexpensive elements but remember that you get what you pay for. And don’ t forget how much you pay for your heavy equipment.
