Papermaking Application: How Self-Cleaning Filters Can Help!
Principle of operation: while water goes into the filter cartridge, the filtered water exits leaving the dirt in the cartridge chamber. As dirt particles collect on the cartridge, the line pressure at the filter outlet drops. As the quantity of these dust particles increases, the pressure reaches a preset differential – the cleaning cycle begins Within a few seconds and without interrupting the main flow the carrier shaft starts revolving the scraper blades, made of stainless steel (also PTFE and PTFE+SST according to the application) which clean the cartridge, removing the dirt from the inside. The ball valve is attached and the dirt comes out of the filter. The above cycle is programmable by the user. Because of the automatic flushing, there is no plant downtime for routine filter cleaning, which translates to greater productivity for the plant.The HC self-cleaning filter not only saves labor costs. It also saves energy and chemical costs due to the lower volume of water used in the back flushing process. The benefits of HC self-cleaning filter may be thus summed up in: "Reduction in water usage, ease of maintenance, simple design, reasonable cost , and improved efficiency on cleaning". HC self-cleaning filters are produced by TECSI S.r.l., an Italy-based company that specializes in industrial and irrigation filtration systems. TECSI range of self-cleaning filters offers a wide choice of capacities and materials, to fulfill the most various needs.
