Talking about the technical standards and suggestions of activated carbon filter

Guangzhou Lvyuan filter element manufacturers briefly discuss and analyze the technical standards and suggestions of household water purifiers and activated carbon filter elements: In real life, due to frequent water pollution incidents and tap water during transportation, it is vulnerable to the secondary pollution of the water pipeline network and water tank. Pollution, there are hidden dangers in the quality of tap water, and household water purifiers have gradually become a necessities of life. However, due to the imperfect standard system of water purifiers and their parts and raw materials, low entry barriers, uneven product quality in the market, and no guarantee of after-sales service, standardization problems restrict the development of my country's household water purifier industry. Guangzhou Lvyuan filter element manufacturer analyzed the standard system of activated carbon filter element and put forward some suggestions. The technical standard of activated carbon filter element: The activated carbon filter element is the most important part of the water purifier, and the quality of the filter element determines the service life of the water purifier and the quality of the water. It can effectively remove color, odor, particulate matter, bacteria, harmful chemical components, etc. in water, thereby ensuring the safety of drinking water. According to the different uses of filtered water, the types of filter elements can be divided into the following categories: ①Activated carbon filter element; ②PP filter element; ③Ceramic filter element; ④Resin filter element; ⑤Titanium rod filter element; ⑥KDF filter material; ⑦Nanofiltration membrane; Filter membrane; ⑨ reverse osmosis membrane (RO). Most of the water purifier products sold on the market are 5-level processes, and in the treatment process of various water purifiers, PP cotton + granular activated carbon + sintered activated carbon + reverse osmosis + post-activated carbon products have a large market share, and activated carbon has a large market share. Filters are widely used. my country has incomplete standards for water purifier filter elements and the importance of activated carbon filter elements. It is very necessary to formulate a more systematic and perfect standard for activated carbon filter elements. Guangzhou Lvyuan filter element manufacturers suggest that you can refer to the following four aspects: 1. In addition to examining the removal effect of CODMn and DOC, it is recommended to increase the test of its total hardness in water, various trace organic pollutants, The removal effect of particulate matter, residual chlorine, heavy metals, microorganisms, etc. Determination method: You can refer to the relevant NSF standards to prepare a water sample with a certain concentration of specific pollutants for a simulated water flow test, and the removal rate can be calculated by measuring the concentration of the incoming and outgoing water. 2. Evaluation of the stability of the activated carbon filter The stability test mainly examines whether the activated carbon filter will leak under normal working pressure, which will affect the water quality. Measurement method: Under a specific pressure, tap water is used to flow through the activated carbon filter element in the forward (reverse) direction, and the changes in the number of particles and turbidity in the water quality before and after the tap water flow are measured. The changes in the number of particles and turbidity can be used to determine whether the activated carbon filter has particle leakage and the severity of particle leakage. 3. Hydraulic characteristic test of activated carbon filter element By measuring the pressure drop curve of the activated carbon filter element, it is used to help select the appropriate filtration flow rate, and in the case of ensuring the flow rate is large enough, the pressure loss can be reduced as much as possible. Measurement method: Take tap water as the water source, and then pass through the activated carbon filter element after being transported by the pump, and measure the change of the pressure value before and after the water sample flows through the filter element. After several sets of tests, draw a pressure drop-flow relationship diagram according to the flow rate and pressure drop values. 4. Evaluation of the replacement cycle of the activated carbon filter The replacement cycle of the activated carbon filter can be evaluated according to the water quality treatment effect of the activated carbon filter and the adsorption performance parameters of the activated carbon in the filter. Guangzhou Lvyuan filter element manufacturer, based on more than 10 years of experience in Ru0026D and production, believes that different water purification technologies, filtration processes and filter elements have different functional characteristics and service lives. The actual service life also depends on the local water quality and usage. Frequency and volume, but flushing the filter element frequently is beneficial to prolong the service life of the filter element of the water purifier, there is no doubt about this.
