Audited Supplier MBR is a combination of membrane technology and bio-chemical reaction in water treatment. MBR filter the sewage in bio-chemical tank with membrane so that sludge and water are separated. On one hand, membrane rejects microorganisms in the tank, which greatly increase the concentration of activated sludge to a high level, thus the bio-chemical reaction of sewage degradation processes more rapidly and thoroughly. On the other hand, water output is clear and of high quality because of high precision of membrane.
This product adopts reinforced modified PVDF material, which will not peel or break during backwashing, meanwhile it has good permeable rate, mechanical performance, chemical resistance and anti-fouling ability. ID & OD of reinforced hollow fiber membrane are 1.0mm and 2.2mm respectively, filtering precision is 0.1 micron. Filtering direction is outside-in, that is raw water, driven by differential pressure, permeates into the hollow fibers, while bacteria, colloids, suspended solids and microorganisms etc. are rejected in the membrane tank.

10. Close the liquid discharge port of the filter, open the bleeder valve at the top of the housing, slightly open the inlet valve, so that the material enters the housing until the liquid overflows from the bleeder valve at the top of the housing, at this time close the bleeder valve. Pay attention to check the disassembly place, whether there is leakage;.
11. Slowly open the filter outlet valve until it is completely open. Indicates that the replacement is complete.
12. Remove the tools used for replacement and cleaning tools. Clean up the surrounding area.
---Bag filter instalation step
1. First of all, it is necessary to confirm whether the accessories required for the installation of bag filter have been prepared;
2. Check the O-ring seal and the O-ring groove on the bag filter in order to replace the accessories in time;
3. When installing the bag filter, it is necessary to place the bag filter on the work station that needs to be filtered. After connecting the inlet and outlet flanges or pipe teeth, fix the filter, smother the exhaust port, or configure the exhaust valve, and the jacket type connects the thermal insulation heat source;
4. Slowly put the metal mesh basket into the bag filter, so that the collar of the mesh basket and the interface of the bag filter can be matched;
5. Place the liquid bag filter, so that the bag filter bag ring mouth as well as the metal mesh basket collar can match;
6. Place the O-ring seal into the O-ring groove, O-ring seal can not be twisted or deformed;
7. After aligning the top cap of the bag filter, tighten the two diagonal hanging caps at the same time, and then tighten all the hanging caps afterwards;
8. Close the exhaust valve installed on the top of the bag filter;
9. Check whether each connecting pipe is firm and whether the working pressure is within the permitted range;
10 slowly open the input valve, so that the liquid can slowly flow into and fill the filter, to prevent the liquid from suddenly impacting the filter bag, resulting in the rupture of the filter bag, and then observe whether there is a leakage phenomenon, if there is no leakage phenomenon can be found directly for filtration.
---Bag filter replacement cycle
PP Bag filter is a kind of water treatment equipment, the filter is often used in some water treatment process pretreatment, is an important pretreatment device; can also be used individually. But no matter in which field, pp bag filter has a certain replacement cycle.
The pp bag filter canister itself does not need to be replaced often, if it must be replaced, then its canister replacement cycle for about 5 years; pp bag filter filter bag needs to be replaced, the replacement cycle of the filter bag ranges from 1 to 3 months. The filter bag is changed diligently because the core of this type of filter operation is the filter bag, and the filter bag will continuously intercept impurities and pollutants in the process of its operation leading to fouling, fouling after the need for cleaning, cleaning more often than the need for replacement.
---How to increase the service life of bag filter
1. Do a good job of water pre-treatment. pp bag filter bag fouling, a large part of the reason is that the water quality is too poor. In order to avoid high turbidity, poor water quality of the feed water, resulting in filter bag fouling blockage, so that the cleaning frequency service life is reduced, it is necessary to improve the quality of the feed water. The key to improve the quality of feed water is to do a good job of water pre-treatment. Only through good pre-treatment, so that the quality of feed water to meet the water requirements, in order to fundamentally solve the problem.
2. Maintain a normal operating load. Although the pp bag filter has a large processing capacity, but then the processing capacity is also a certain upper limit, more than its upper limit will inevitably lead to an increase in the operating load of the filter, which will lead to a reduction in the service life of the filter bag and filter itself, and shorten the replacement cycle. Therefore, maintaining its normal operating load will help extend its replacement cycle and will not lead to the need for faster replacement.
3. Adopt the habit of timely cleaning. As mentioned above, the filter bag will continuously retain pollutants and impurities in the process of filter operation, and these impurities are attached to the filter bag for a long time, which will gradually form a fouling blockage. These blockages will deepen with the extension of time, resulting in the filter bag can not be cleaned to restore performance. Therefore, in addition to the user to improve the quality of incoming water, the preventive cleaning of the blockage is also to do.
---Why use salt in PE salt tank? What kind of salt is needed?
PE salt tank, as part of water softening unit, is mainly used to hold NaCl salt solution (brine). It is generally made of PE material and contains a salt grid and a salt well. Salt valves are also installed in the salt wells to ensure the automatic operation of the water softener. So why use salt in water softening treatment? What kind of salt is needed?
During the softened water generation reaction, the Na+ in the resin needs to adsorb Ca2+ and Mg2+ in the raw water to obtain softened water. When the resin absorbs a certain amount of calcium and magnesium ions, its absorption efficiency will gradually decrease. At this point, it needs to be regenerated. The resin layer is cleaned with brine in a salt tank to replace the calcium and magnesium ions on the resin and discharged with a waste solution. If there is a lack of salt, the calcium and magnesium ions in the water cannot be removed after the resin reaches saturation and softened water production cannot continue. Therefore, the desalinated water equipment needs salt to ensure its better operation.
What kind of salt is used in the PE salt tank? Is it table salt?
Is it table salt in the salt tank? Of course not. Water softening equipment uses special salt, also known as ion exchange resin regenerator, also known as water softening salt. Its main chemical composition is sodium chloride (NaCl), purity is greater than 99.5%. Sodium content in line with national standards, can effectively remove hardness (other water calcium, magnesium ions and some alkali impurities), regeneration restore resin.
Can I use industrial salt in the water softening tank? What is the difference between it and water softening salt?
Industrial salt should not be used in water softening tanks. Industrial salt not only contains a single substance sodium chloride, but also a variety of substances collectively referred to as industrial salt, such as potassium nitrate, potassium chloride, sodium nitrite and other industrial substances, can be called "industrial salt".
The special salt for water softening equipment is in the form of mothballs, with special additives. Pure white, no impurities, purity of 99.5% or more. It can effectively remove calcium, magnesium ions and some water alkali impurities in water, regenerate and restore the resin, and keep the water without scaling.
Calculation of salt consumption of water softening equipment
Salt is needed for salt absorption and regeneration of water softening equipment, and salt consumption should be calculated according to the requirements of inlet hardness and outlet water quality. Theoretically, the salt consumption of the resin regeneration of desalinated water equipment has nothing to do with the inlet hardness, but only with the working exchange capacity of the resin. In general, the amount of regeneration liquid of water softening equipment is 2~3 times of the filling volume of resin, i.e., each litre of resin needs about 160g of salt.
In summary, salt is a continuous consumption of water treatment consumables. It should be added before the salt in the PE salt tank is depleted, and can be added up to one quarter of the standard salt tank.
