7 steps to choose the water filter cartridges for liquid filter housing

At present, there are many kinds of filter cartridges in this market, for example: PP melt blown filter cartridges, String wound filter cartridges, Fiberglass filter cartridges, Stainless steel filter cartridges, PP pleated filter cartridges, PES pleated filter cartridges, PVDF pleated filter cartridges, PTFE pleated filter cartridges, Titanium filter cartridges, and so on. Different water filter cartridges can be met different filtration application area. Therefore, how to choose the suitable filter cartridges for our liquid filter housing or our filter equipment? 


In generally, the filtration divided into pre filtration, microfiltration, ultrafiltration, nanofiltration and reverse osmosis filtration. The pre filtration can only remove suspended substances, colloids and sediments.The ultrafiltration and nanofiltration can remove the 99.8% bacteria and macromolecular substances. In theory, the reverse osmosis can purify water to 100%, so the water after reverse osmosis filtration can be called pure water. It can remove almost harmful and beneficial components in water, including minerals. Ultrafiltration and nanofiltration are ideal water treatment methods for household water filters. Ultrafiltration is suitable for general tap water, and the nanofiltration is more suitable for tap water with poor raw water quality. 


Due to the filter cartridges with different model No., and each model No. have different working temperature and pressure requirements. Therefore, how we choose the correct filter cartridges for our filter housing?


1) The requirements for filtering water. Firtly, we should know what's our requirments for the water after filtration? Then we can choose the filter cartridges to pre filtration or deep filtration? To reach a effective filtration and the cost budget.


2) The sequence for the filter cartridge filtration accuracy: if we have 2 stage or 3 stage filtration process, we should choose the filtration accuracy from bigger to smaller, for example, from 50 microns, to 20 microns, and last stage should be 10 or 5 microns.


3) The maximum working pressure, different kinds of filter cartridges material will have different working pressure capability. 


4) The maximum working temperature.


5) The requirements for the flow rate per hour.


6) The result for the liquid filtering, is it for municipal tap water use? Or for medical use? Or for drinking water?


7) Whether the liquid contains a strong acid or strong alkali.


Our company can supply various of filter cartridges, PP melt blown filter cartridge, sediment filter cartridge, pleated filter cartridge, high flow water filter cartridge, industrial water filter, micro filter, titanium water filter, string wound filter cartridge, cotton filter cartridge, stainless steel 304 filter, stainless steel 316L filter, and so on. We are the professional manufacturer and have up to 10 years experience for water treatment. Any requirements or ideas pls feel free to let us know and we will give you a good suggestion. Looking forward to our business cooperation !

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
