Type of different flow characteristics and performance are also different water filter, the existence of the PALL big flow water filter have what advantage? What problem can be solved in the actual? Use after a period of time, what are the matters needing attention in the aspect of maintenance?


PALL big flow water filter carrying is convenient, its filter layer from the water to the water, the aperture from coarse to fine, ensure that the impurities remaining in the filter element, avoid secondary pollution.


it is outside into the inside structure and go out into the structure of two kinds of way, make it easier to replace, at the same time ensure that the pollutants block inside the filter element. In addition the equipment scope of application is very wide, whether startup is still the runtime can use in succession.


PALL big flow water filter adopts horizontal pleating skills, in limited space inside the filtering area, at the same time, to ensure that the per unit area have fluid through the filter medium, effective filtering area of conversion rate and the efficiency is very high.





PALL big flow water filter maintenance methods and techniques:


(1) check the o-rings first, and then clean the end of the filter seal, flat on seal groove;


soak o-rings (2) using the process liquid;


(3) to get off bags, cover head, tighten the rings hold-down bolts;


4. Put the shell at the top of the valve open effectively;


5) to the inlet valve open a bit, make the liquid into the shell until the issue from the bleed valve, close the purge valve.


6 gradually will effectively open the outlet valve, and then slowly turn the inlet valve effectively;


7 to 10 'filter with flow rinse 5 ~ 10 minutes;


end filter cannot support big traffic impact, also can't let its opposite direction under pressure.

Before we understand the pure water machine, we first need to know to what are the kinds of pure water machine. Generally divided into household pure water machine, pure water machine box wall hanging type, commercial pure water machine, pure water machine big industrial pure water machine.
household pure water machine, pure water machine is also called the kitchen type kitchen type pure water machine using the filter under general is given priority to with ten inches, or 11 'filter. Suitable for this kind of machine filter with PP filter, the CTO filter, UDF filter, containing mineralized material such as filter, also have softened water quality resin filter, the filter is in a 10 inch filter in the bottle. The main role is with dirt filter, filter out water purification, improving taste.
hanging in the pure water machine using filter is a one-piece filter, one-piece filter has the advantage of using quick joint, directly on can use, more safe and quick. One-piece PP filter mainly are an organic whole, integrated compressed carbon. One carbon particles, improve the taste of T33 filter and filter. The main role is to use filter dirt, filter out water purification, small T33 is to improve the taste.
commercial pure water machine is generally use 20 inch pp filters, and 20 inch filter form basic and 10 inch is the same, only difference in different sizes, used in the machine is different, different filter bottle.
in the pure water machine is used to filter include ultrafiltration membrane, RO membrane and liquid membrane filter, this filter filter the pure water machine, mainly occupies an important position in the pure water machine.
the one-piece filter also launched a Korean fast connect filter, filter in the market for years to come, one-piece filter will occupy the dominant position. Shenzhen dow is currently the domestic production of filter manufacturers, the production of filter is higher than dozens of varieties, the quality is strictly guard a pass, the screening, safe and reliable quality, is your choice of pure water machine filter.

folded filter interface model is what?


when it comes to folding filter joint, small butterfly last had a customer because of the type 222 fold cartridge interface didn't confirm clear and mistake, lead to later can't use, so we are buying folded filter, be sure to check out the model of the interface, since there are different according to the structure of the filter, many different kinds of interface, only match the size of the interface and filter cartridge can be used, or it is too big to put in, too small and is very loose, no seal, sometimes manufacturer filter tag will write the model of the interface, but a lot of clients is a stranger to folding filter model, in order to better help customers understand folded filter interface model, under the small butterfly to introduce folded filter commonly used models and the size of the corresponding interface. Commonly used models are as follows:



interface type and size model inside diameter ( mm） The outside diameter ( mm） Contain o-rings diameter ( mm）
226 type 43. 9 56. 5 58. 7
222 type 32. 1 to 44. 3 45. 5
type 220). 6 to 33. 9 35. 6
215 type 23. 131. 3 to 33. 6 2229

thread type (M36 thread type 2935. 7

The filter element determines the water quality of the water purifier. When purchasing a water purifier, pay attention to the efficiency of the filter element in filtering water. At present, most of the water purification processes use activated carbon filter, microporous ceramic filter, membrane separation and other methods. However, as the use time increases, the working capacity of the filter element decreases with the amount of water treated, and the filter element needs to be replaced in time. The purification principle of ceramic filter element is similar to that of activated carbon, but it has relatively good filtering effect and long service life, but it cannot completely remove bacteria. Membrane separation filtration type, mainly including microfiltration, ultrafiltration, fine filtration and reverse osmosis and other processes. 1. It can effectively prevent the activated carbon powder from entering the RO membrane, and protect the RO membrane to minimize the entry of activated carbon powder and prolong its service life. Because before installing the activated carbon filter element, no matter how clean it is, there will be carbon powder flowing out. Installing a 1μm filter element before the RO membrane can act as a barrier, greatly reducing the possibility of artificial pollution of the RO membrane. 2. The filtration accuracy of 1μm PP cotton is 1 μm, and harmful substances such as bacteria, sediment particles, and rust larger than 1 μm can be removed as much as possible. When the first 5μm filter element fails, it can still protect the RO membrane and reduce the RO membrane. probability of contamination. 3. If the third stage is block compressed activated carbon or sintered activated carbon CTO, three of the five stages of filtration are activated carbon, and the activated carbon filter element is reused, which not only wastes resources, but also increases costs. Losing its due effect is not worth the gain. The second stage is generally granular activated carbon, which needs to be washed during installation, which often causes a lot of black water, and it is easy to be washed out. If it is changed to compressed activated carbon black water, the problem will be solved, and the burden of the third-level PP cotton will not be increased. The first three-stage filtration of the water purifier is for the pretreatment of the reverse osmosis membrane. As the pretreatment of the raw water, it is to increase the service life of the reverse osmosis membrane, so the first filter element of the reverse osmosis membrane of the water purifier is still 1μmPP cotton is better.
