The Self-cleaning filter is a type of mechanical filter that was invented in the early 20th century. The first self-cleaning filter was patented in 1907 by John W. Kennedy. Self-cleaning filters are used in a wide variety of applications, including swimming pools, aquariums, and industrial wastewater treatment.
Self-cleaning filters work by using a rotating screen to capture debris and particles. The debris is then flushed away with water, leaving the filter clean.
A self-cleaning filter is a type of filter that cleans itself automatically. It is used in many industries, including food and beverage, pharmaceutical, and chemical. Self-cleaning filters are available in a variety of designs and sizes. They can be made of different materials, such as stainless steel, carbon steel, or polypropylene.
A self-cleaning filter is a type of filter that cleans itself automatically. It is typically used in settings where there is a lot of dirt and debris, such as in industrial settings or hospitals. Self-cleaning filters can be either mechanical or electronic. Mechanical self-cleaning filters use a variety of methods to clean themselves, such as brushes or compressed air. Electronic self-cleaning filters use an electrical charge to remove dirt and debris from the surface of the filter.
The self-cleaning filter is a great product for those who want to reduce the amount of time and effort spent on maintaining their filtering system. This type of filter eliminates the need for backwashing, which can save a lot of water and energy. In addition, it can reduce the number of chemicals needed to clean the filter, making it a more environmentally friendly option.
Benefits of Self-cleaning filter
Self-cleaning filters are an important part of keeping your swimming pool or hot tub clean and sparkling. They remove dirt, debris, and bacteria from the water so you can enjoy it without worry. They are easy to install and require little maintenance, making them a great choice for busy people.
Self-cleaning filter / Backflush filter / Automatic strainer / Bernoulli Filter
Ultra Tec Water Treatment is a range of self-cleaning backflush filters that are extremely wide. It consists of the self-cleaning Bernoulli filter (automatic filter), the KRF filter (Krone backflush filter), or the new development the two-stage combined filter uses the event of the KAF self-cleaning filter as a prefilter right down to mostly 200 or 500 microns and therefore the second stage fine filtration.
Self-cleaning automatic filter
Self-cleaning automatic filter, which doesn’t only use the backflush effect caused by the straightforward pressure drop to outside lower pressure than the working pressure – the Bernoulli self-cleaning backflush filter creates it ́s own backflush effect within the gap between the cleaning disc and therefore the strainer insert. The insert is often made out of wedged wire profiles or a perforated plate. In some special applications also chrome steel or alloy mesh is employed. the jammed wire filter screen is often made out of chrome steel SS 316 or materials like a super duplex or duplex SS. If the perforated plate is employed for filter degrees over or 1 mm then also chrome steel and also duplex Ss or titanium perforated plates are used. this type of self-cleaning filter has the following operating features.
Effect causing pressure drop used for insert cleaning
continuous filtration during all operation levels Reliable cleaning function under heaviest solid loads
Filter mesh from 0.1-50 mm Large particle size removal / Maximum particle size not limited by the cleaning mechanism “no-touch” cleaning effect Very low loss / DP caused by the filter.
Works and performs cleaning with low as 0.1 bar like water column pressure or maybe in vacuum condition
Easy to regulate and operate in EX / hazardous area classified zone in LNG/LPG/liquified gas company
Heavy-duty design for seawater applications.
Most applications for this filter are device protection also as plate heat exchangers / PHE or shell and tube heat exchangers or condensers. The filter is often used in all types of industrial applications and may filter fluids whit sizes from 1“ up to 40“ the special design M-KAF up to 72“.
Industrial procedures and processes require clean water or process liquids that are freed from solids and contaminants. Open water systems place particularly high demands on filtration in terms of separation quality and process safety under continuous operating conditions. The filter described here operates on the Bernoulli principle, which is well-known within the field of hydromechanics. Over 250 years after the physical processes were discovered by Bernoulli (1700 – 1782), his discovery is being utilized within the filtration process utilized in systems under continuous operation.
However, ever-increasing importance as an impact of the filter system described here is being attributed to the invention that not only particles and contaminants are captured and filtered out from a selected slot width/filtration level upwards, but also that mussel and snail larvae that are smaller than the slot width are destroyed, thus significantly reducing their population. the automated filter operating on the Bernoulli principle is distinguished by its simple, compact design and may be installed in any mounting position. Using corrosion-resistant materials ensures reliability, minimal maintenance costs, and a high level of plant safety, even in saltwater systems or when corrosive media are used.
Self Cleaning Filter
Minimum backwashing water consumption Filtration degrees from 50 up to 1000 microns & Flow rates between 3 and 280 m³/h.
Self-cleaning filters are designed specifically to provide efficient filtration for liquids, including those of high viscosity, requiring continuous filtration without interruption to the flow during the cleaning process. There is no operator contact with the process fluid.
The filter is available for either manual or fully automatic electric or pneumatic operation. The range of optional control devices makes it particularly suitable for continuous processes and services with high contamination levels.
