Introduction to activated carbon filter technical standard and suggestion

Dongguan fine filter cartridge manufacturer mainly analyze the technical standard of domestic water purifiers and activated carbon filter and Suggestions: in real life, due to the frequent water pollution incident and tap water in conveying process by water conveyance pipeline network and the secondary pollution of water tank, tap water quality existence hidden danger, household water purifier has gradually become the necessaries of life.
But because of the water purifier and its spare parts, raw materials of standard system is not sound, barriers to entry is low, the quality of the products on the market the good and bad are intermingled, after-sale protection, no standardized problem restricts the development of the household water purifier industry in our country.
Dongguan fine filter cartridge manufacturer of activated carbon filter is analyzed standard system, puts forward some Suggestions.
activated carbon filter technology standards:
activated carbon filter is the most important part of the water purifier filter is good or bad determines the service life of water purifiers and water quality. It can effectively remove the water colour, smell, particulate matter, bacteria and harmful chemical composition, etc. , so as to ensure the safety of drinking water. According to the different filter water use, the kinds of filter can be divided into the following categories: (1) activated carbon filter. (2) PP filter; (3) ceramic filter; (4) resin filter; (5) titanium rod filter; 6 KDF filter material; All landowners nanofiltration membrane; Today hollow fiber ultrafiltration membrane; Pet-name ruby reverse osmosis membrane ( RO) 。 The water purifier products are sold on the market in more than a category 5 process, and in all kinds of processing technology of water purifiers, PP cotton + sintering activated carbon granule activated carbon + + reverse osmosis + rear activated carbon products market share is bigger, activated carbon filter is widely used.
the water purifier filter criteria insufficiency in our country and the importance of the activated carbon filter, to develop a more specifically for activated carbon filter system, perfecting the standard is very necessary. Dongguan fine filter cartridge manufacturer recommended reference from the following four aspects:
1, activated carbon filter water purification effect evaluation in addition to the investigation of CODMn, DOC removal effect, suggested adding test its total hardness, all kinds of trace organic pollutants in water, particulate matter, quantity, residual chlorine, heavy metals, such as microbial removal effect. Method: refer to the NSF standards, preparation with respect to a certain concentration of specific pollutants simulated water samples test, by measuring the concentration can be calculated in and out of the water removal rate.
2, activated carbon filter stability evaluation stability test focuses on activated carbon filter will happen in the normal working pressure activated carbon leakage, which affect water quality. Method: under certain pressure, using the tap water is ( Inverse) To flow through the activated carbon filter, determination of particulate matter in water quality before and after the water flows through the quantity, the change of turbidity. Through the particle number and the change of turbidity can be used to determine whether the activated carbon filter particles leaks occur, and the severity of the particles leaked.
3, activated carbon filter water feature test
by measuring the pressure drop curve of the activated carbon filter, used to help select appropriate filtration velocity, in guarantee under the condition of flow is big enough, as far as possible to reduce the pressure loss. Method: tap water as water source, after pump by activated carbon filter, the determination of water samples through the filter before and after the change of the pressure value. After multiple sets of test, according to the flow numerical mapping pressure drop and pressure drop. . . Flow diagram.
4, activated carbon filter replacement cycle evaluation of activated carbon filter replacement cycle can be based on the activated carbon filter water treatment effect, combined with activated carbon adsorption performance parameters to evaluate in the filter.
dongguan fine filter cartridge manufacturer with 10 years experience in research and production, think water purification technology, filtering process and filter also has different functional characteristics and service life of the actual service life also depends on local water quality condition and the use of the frequency and quantity, but often flush filter is beneficial to extend the service life of water purifier filter core, this is without a doubt.
