Unbidirectional Ceramic Filter

Bacteria: Unbidirectional ceramic filters are quite effective at removing bacteria from water. Few bacteria are smaller than one micron in size. Unable to pass through the pores, the bacteria are filtered out as the water seeps through the unbidirectional ceramic filter. unbidirectional ceramic filters rid water of about 99% of pathogenic bacteria, including E. coli, shigella, and salmonella. Microbial cysts, such as Giardia and Cryptosporidium, are also too large to pass through the filters and are easily removed by the ceramic shell. The silver ion impregnation makes ceramic filtration especially advantageous to those with microbiologically unsafe drinking water. Silver ions are toxic to bacteria, further nullifying bacterial contaminants and preserving the cleanliness of the filter’s surface.
Sediment: Particulate matter like dirt, debris, and rust is effectively filtered out by the unbidirectional ceramic filter’s porous surface.
Turbidity: Turbidity is cloudiness caused by suspended particles in the water. This turns your water unappetizing shades of yellow and brown. unbidirectional ceramic filters adeptly remove the murky coloration from water and restore its clarity.
Chlorine (if filter contains activated carbon): Chlorine is present in most city water because it is used in the municipal purification process. Chlorine leaves water with a bitter chemically taste and an unpleasant smell. The activated carbon reduces both chlorine and chloramines in water, restoring your water’s fresh flavor.
VOCs (if filter contains activated carbon): Volatile organic compounds, or VOCs, include a wide array of chemical contaminants that make their way into water by way of everything from agricultural runoff to consumer products like paints and pesticides. These compounds are all carbon-based, and unbidirectional ceramic filters with carbon cores will greatly reduce the levels of VOCs in your water.
Heavy Metals (if filter contains ion exchange resin): If the ceramic element contains an ion exchange resin, heavy metals like lead, mercury, copper, and zinc are greatly reduced in the water.

Unbidirectional ceramic filters can be used in under-sink installations, other point-of-use applications, or as portable filters you can take on camping trips or elsewhere. The most common application for ceramic water filters is point-of-use drinking water. Because of its 0.5 micron filtration, simple upkeep, and low cost, a unbidirectional ceramic filter makes an excellent countertop or under-sink filter in households. The gravity-fed filters can provide you with clean water in your kitchen and be taken on hiking and camping trips. If installed with the proper cartridge, you can pour stream water into the filter and make it drinkable. unbidirectional ceramic filters are also ideal for anywhere where space is limited, like an apartment or RV. A double open-ended unbidirectional ceramic filter can be inserted into any standard 10-inch water filter housing and used in conjunction with other filters, like a sediment filter or anti-scale filter.

Powder preparation process
Dielectric ceramic powder and additives according to a certain proportion of ingredients, after ball milling and mixing, drying and sieving, in the sintering furnace at high temperature for a certain period of time, to remove impurities in the powder, and then in the pre-sintered material to add monomers, crosslinking agents and solvents, etc., after the mill ball milling to obtain ceramic slurry, in the spray granulator atomization and drying, drying of particles that is good fluidity of the spherical pellets.
Ceramic powder formula is one of the key factors in determining the performance of the filter, but also the core competitiveness of ceramic dielectric filter companies, acid and alkali control is unreasonable, impurities, etc. will damage the quality of the powder, and ultimately affect the performance of the filter.
Dry molding
Dry compression molding is the granulation of good powder into the mold, through the indenter to apply pressure, indenter displacement in the mold cavity, transfer pressure, so that the powder particles in the mold cavity rearrangement deformation and compaction, the formation of ceramic billet with a certain strength and shape.
The denseness of the ceramic billet will affect the Q value of the filter, so the choice of pressure and holding time parameters for dry press molding is equally important.
Sintering
Blanks at high temperatures, with the extension of time, and finally become a hard polycrystalline sintered body with a certain microstructure, this phenomenon is called sintering. Sintering is to reduce the form of the body in the pores, remove impurities, enhance the combination between particles, improve mechanical strength of the process.
Improvement of the sintering process of ceramic dielectric filters can significantly affect the performance of ceramic filters, the sintering temperature and holding time are important control parameters that determine the grain size and density of the ceramic, which in turn affects the mechanical strength and polarization of the ceramic.
CNC machining
CNC machine tools are used for grinding to precise the dimensional accuracy of the ceramic dielectric substrate.
Metallization
Using chemical plating, spraying, sputtering, screen printing and other processes in the ceramic media substrate coated with silver, after the silver baking furnace burns silver, can use laser equipment to adjust the silver plating layer.
Assembly and commissioning
The ceramic dielectric substrate and other accessories such as PIN pins are assembled to test the passband bandwidth, insertion loss, etc. of the filter and debugging.
The debugging process of ceramic filters is complicated. Compared with traditional cavity filters which are debugged by adjusting the resonance rod, the debugging of ceramic filters can only be realized by grinding, and due to the irreversibility of ceramic grinding, the debugging of the product has become the key to improve the production capacity.

One-way ceramic filters are a commonly used filtration device for separating solid particles from liquids. The following is the general one-way ceramic filter operation method.
Preparation: Select the appropriate ceramic filter plate according to the filtration needs and clean it. Check all parts of the filter to ensure that the equipment is operating normally.
Introduce the liquid to be filtered into the material tank of the one-way ceramic filter through the guide pipe or pump.
Open the feed valve so that the liquid flows into the annular space between the filter plate and the pump.
Turn on the pump, the liquid passes through the pores of the filter plate, the solid particles are filtered on the surface of the filter plate, while the clean liquid passes through the filter plate and flows to the discharge valve.
Clean the filter plate regularly: When the surface of the filter plate is blocked by solid particles, the filter plate needs to be cleaned. Close the feed valve and stop the pump. Open the cleaning valve, use cleaning liquid or water to clean through the filter plate. When cleaning, the particles on the filter plate can be rinsed off by pressurizing or backflushing.
After cleaning, close the cleaning valve and open the feed valve and pump to resume filtering operation.
When the filtration speed of the liquid slows down obviously, it may be that the filter plate is blocked or the pressure drops, so it is necessary to stop the filtration operation and clean or replace the filter plate.
After the filtration operation is completed, close the feed valve and pump, and close the discharge valve. Empty the liquid in the filter.
