what are commonly used cartridge filters in water filter housing ?

Commonly used cartridge filters can be divided into the following types:


PP cartridge filter 


Pp filter called pp melt blown filter cartridge, It is fusing and intertwined of polypropylene fiber, fibers randomly forms 3D micron pore structure in space, and the pore size of the pores is distributed along the flow direction of the filtrate, and the pore size of the pores is distributed along the flow direction of the filtrate cartridges fine fibers in surface , coarse fiber and deep filtration to remove impurities of different particle sizes. The filter has a precision range of 0.5-100 um, and its flow rate is 1.5 times or more of the same precision pleated filter. It can be equipped with different types of end cap joints to meet the need of various engineering installations.


String wound cartridge filter


It is made of high filtration capacity textile fiber wined tightly within the string in the poly-porous core. The string material has polypropylene string, absorbent cotton string, acrylic fibre yarn, fiberglass. By controlling the winding tightness and the density of the yarn during winding, it is possible to produce filter cores with different precision, which can effectively remove suspended solids, particulate impurities, etc, various filter media fit with various liquids application.


Pleated cartridge filter 


Pleated filter is made of polypropylene, hydrophobic PTFE. Nylon, polyethersulfone membrane media and non-woven support material, the material of cage and end caps are polypropylene, with small volume, a large filtration area, high precision, etc. features. Filtration accuracy can range from 0.1 um to 60 um. The filter end cap seal and the integral structural connection are all thermally welded without the uses of glues or adhesives to prevent any possibility of pollution. The filter connector is of three international types: 222 connector, 226 adapters, flat end cap. The products undergo rigorous and complete testing before leaving the factory to ensure stable performance.


Carbon cartridge filter


Sintered activated carbon filter is shaped by mixing activated carbon powder material and macro-molecule hot melt pore forming material, pouring into a special mold, and sintered at a 200-300 high temperatures. It has adsorption, filtration, interception and catalysis features, which have high effectively remove organic matter, residual chlorine and other radioactive substances in water, and has effects on Decolorization and odor removal. 


Titanium cartridge filter


Titanium filter has acid & alkali corrosion, high temperature resistant, high strength, easy to ensure filtration accuracy, easy to regenerate, etc. Titanium water filter is formed by titanium powder sintered at high temperature , not easy to fall off, the working temperature can up to 500 ~ 600℃ in air, suitable for filtering various corrosive media, such as, hydroxide, seawater, other liquids filtration of chloride solutions such as iron, copper, sodium. 


It has excellent mechanical properties, can be machined by cutting, welding, etc, with high compressive strength, max.Operating pressure differential up to 2 MPA. Even if it is working under high temperature and high pressure, the filter will not be deformed. Its filtration precision has guaranteed, the porosity is up to 35~45%, the pore size distribution is uniform, large dirt capacity, and the regeneration method is simple, and can be reused after regeneration.


Stainless steel cartridge filter


Stainless steel filter features：


1. Good filtration capacity, good performance for filtration 2-200um particle size.


2. Good corrosion resistance, temperature resistance, pressure resistance and wear resistance


3. Stainless steel filter pores uniform, precise filtration accuracy.


4. The large flow rate per unit area of the filter element.


5. Fit to low and high temperature, reusable and washable, less labor cost.

How to Hang a Suspended Ceiling From Steel Beams

The suspended ceiling hangs under the roof or floor structure above, hiding ugly mechanical and electrical equipment from the view, while also allowing you to easily reach these equipment as needed.While wooden frames usually support such ceilings, in rooms where metal frames are used instead of traditional wood, you can also hang ceilings from steel beams.Hanging the ceiling from the beam requires you to use a special clip to connect the support line to the beam without compromising its structural integrity.Measure 4 inch down from the bottom of the lowest beam, pipe or pipe in the ceiling space.If you plan to use panel fluorescent lamps in your ceiling, add an additional 2 inch to this measurement.Make a mark on the wall indicating the location of the facade.Set up a laser level to extend the mark you made on the wall to the entire wall length.Draw a chalk line on the wall to mark the position.Mark all four walls repeatedly with chalk lines indicating the height of the ceiling.Instal

Importance of Calibration Service, Material Testing

When it comes to Calibration services, genuine service providers offer full recall system and data sheets for all items calibrated. Service needs to be instrument specific. With the advent of technology, Calibration service has seen a tremendous change and has gone through various phases to get the top quality. Calibration is a great deal for industrial purpose. It makes sure that products are manufactured as per specification. It also checks the competence level of technically valid results. The calibrated measuring instrument helps in checking the quality and valuation of the product. In cases of electronic equipment, it is essential to calibrate instruments to keep a check on quality and performance. Calibration facilitates in improving measurement abilities. Calibration service can be manual or automated.  textile testing equipment manufacturers Material Testing machines are available for a wide variety of industries including materials testers for plastics, textiles, adhesives, fi

Level Measurement Solutions

Makeup water treatment is an important component of steam generation. It is the means to resupply the system with water suitable for boiler and other operations that, was lost in the cycle.The steam generation cycle, level control for the water treatment process is not necessarily about efficiency, but rather, accuracy, reliability and safety, while providing proper inventory management to ensure chemical and makeup water supply meets demand. The focus is on the chemical component of the makeup water treatment since it presents difficulties for level technologies that may work perfectly on non-chemical applications related to the water treatment process or those with limited variations in the contents of the vessel's vapor space. Although important measurements such as ammonia, acid, caustic and other chemical storage tanks are not difficult level applications by any stretch, small nuances in how the vessels are monitored relative to level technology can have a dramatic effect on t
