It should be noted that the steam valve should open slowly to avoid a sudden surge of steam, and damage to the cartridge.Note: If you require frequent steam sterilization, to the supply-side instructions, in order to provide resistance to steam sterilization filter in the purchase of a filter.② For newly purchased cellulose acetate filter should only be using disinfectant to sterilize, and not with steam sterilization.b stainless microporous film of cleaning of the filter housing① pipes and valves of the new stainless steel microporous membrane filter housing as well as before and after purchase, you must use detergents its oil inside and outside processing adhesion and adhesion of dust and dirt during transport material thoroughly cleaned;The ② longer good disinfectant soak into the configuration, disinfection and sterilization;③ then rinse rinse until no residual disinfectant.

With the passage of time, in order to maintain the proper filtration rate, and gradually to increase the pressure within, but can not exceed the maximum pressure within the filter is not The maximum allowable operating pressure of the filter of the same material.When the internal pressure is already high and the filtration speed and slow down more, they should be parked on the filtering operation and the filter clear.b, microporous membrane filter elements backwashFine filter for mineral water as well as water treatment, recoil optional cleaning recoil after recoil and then the terminal filter the clean water can again put into production.② For beer, beverage and other fermentation liquid and sugar-containing liquid filtration, it is recommended to adopt the pre-treated clean oil-free compressed air blowback, then clear water red hair, use clean water filtered by the terminal recoil clean can put into production.③ filter adaptation time is long, the recoil after the method described above, the filtration speed is still complex shall ideal enough to filter Removing, placed in a concentration of 2-4% NaOH solution was soaked for 4-8 hours in the by terminal filtration clean water rinse until no residue. Rinse with water until no residue Stay detergent, and then install it.(4) microporous membrane filter is installed, the application of steam to conduct a comprehensive disinfection filtration system, the vapor pressure shall not be higher than the 0.15mpa, sterilization time 20 minutes. Disinfection system even after a comprehensive inspection of all fastening bolts loosening and retightening.⑤ steam sterilized before must first steam pipe steam condensate drained slowly open the steam valve disinfection.⑥ gas to be filtered must be dehumidified, it dropped ≦ 70% relative humidity; is filtered compressed air, should be first compressed air off oil filter before. Operation, out of the gas valve should open slowly.(7) When the microporous membrane filter by fermentation tanks in addition to the open-CO2 stripping, the filter should be installed on the fermentation platform to prevent the fermentation broth back.

First, in establishing a new "O" ring coated with clean filtered liquid as a lubricant, and then filter careful a vertical socket inserted into the lower part of the filter board, such as pump use 226 interface, should interface binaural inserted into the chassis, "O" pending filter change after entering the jack clockwise into binaural card into the chassis empty hole tank. Caught Industry and Commerce and tighten the bolt seal.microporous membrane filter system flush after than Johnson with water the entire filtration systems, rinse thoroughly.c, microporous membrane filter is rinsed clean of the entire filtration system filtering operation.

A microporous membrane filtercartridge the folding drum microporous membrane filter, filter housing diameter of 2.7 feet (ie 69mm), the length of the filter 10, 20, 30 and 40 feet (ie: 250, 500, 750 and 1000mm) four, with the way the sub-filter housing seal plug-in (further divided into 222. Block 226) and flat mouth type two. Are as followsa plug-in microporous membrane filter element, including 222 and 226, is the interface of the filter and filter flapper International Standard No. 222 is "O"-shaped socket 226 is "O" shaped interface with a pair of projections ear, when tipping card into the recess of the filter housing socket board to the upper end of the fixed filter.b, flat nozzle type filter upper and lower ends are flat plate, the filter and filter housing socket link with the plane of the ring is fixed.Filter (such as home water purifier filter, etc.) can also be based on the needs of users, specifically for the design and manufacture of special specifications and uses. Long-term supply of "O"-ring face seals.2, a filterMicroporous membrane cartridge filters microporous membrane filter and stainless steel housing and, if necessary, stainless steel pipes, valves.The lower portion of the microporous membrane filter has a socket cartridge socket board with the jack for the use of the socket filter. Depending on the user processing flow filter single-core 3-core, 5 core, until dozens of filter. At the same time, in order to filter to facilitate loading and unloading, the housing divided into two parts, with fast loaded bolt connection. View Details
