Underground Bore Water Filter Treatment Purification System

Introduce:

Drinking water purification system is mainly used to obtain purified water, mineral water, and pre-treated water for various beverages. Substances, such as organic substances, microorganisms, chlorides, colloidal particles, and residual chlorine. In addition, the system also filters metal ions, reduces the hardness of the water, and makes the water quality fully meet the drinking water standard.

Primary pretreatment (sand filtration):

The main purpose of the use of the multi-media quartz sand filter is to remove the health-hazardous substances containing sediment, manganese, rust, colloidal substances, mechanical impurities, suspended substances and other particles above 20UM in the water. The effluent turbidity is less than 0.5NTU, CODMN is less than 1.5mg/L, iron content is less than 0.05mg/L, and SDI is less than or equal to 5. Water filter is a process from "physical-chemical". When water passes through particulate matter, it is isolated to filter out impurities and colloidal suspensions in the water. The filter is an effective purification of water, and the treatment in the main process of preparing pure water is an indispensable process.

The second stage of pretreatment (carbon filter):

Activated carbon filters are used to remove pigments, odors, a large number of chemical and biological organisms in the water, thereby reducing the residual value of harmful pollutants such as water pollution and pesticides. The difference between the structure of activated carbon filter and quartz sand filter is that the activated carbon has strong adsorption capacity. It is removed through the quartz sand filter, does not filter organic matter, absorbs residual chlorine in the water, and the water consumption is greater than or less than 0.1ML/M3 of chlorine, and the SDI is less than or equal to 4. Both are strong chlorine oxidizers, and there are different types of damage to the membrane, especially the reverse osmosis membrane is more sensitive to chlorine. In addition, during the activation process, some non-crystalline parts of oxygen-containing functional groups are formed on the surface of activated carbon. These functional groups can chemisorb activated carbon to catalyze and oxidize bad news, restore performance, and can effectively remove some metal ions in water.

The third pretreatment step (resin softener):

The cationic resin used to soften water is mainly to remove the hardness in the water. The hardness of water is mainly composed of calcium (Ca2+) and magnesium (Mg2+) ions. When the hardness ions containing raw water pass through the resin layer, Ca2+ and Mg2+ are adsorbed and exchanged by resins and other objects. At the same time, the flow of Na+ sodium ions from the water softener is released The quality in the water is inhibited by the hardness ions of the soft water. In order to effectively prevent the scale of the reverse osmosis membrane. The system can automatically reverse, and so is red

Reverse osmosis system:

Reverse osmosis technology is used for desalination. The reverse osmosis membrane has a pore size of only 0.001 microns, which can remove harmful dissolved solids, bacteria and viruses. The salt rejection rate is as high as 99.6%. Purified water is produced in accordance with national standards. The host part includes safety filters and high pressure. The high-pressure pump is one of the basic equipment of the reverse osmosis membrane element. It provides enough pressure to overcome the resistance to pressure permeation and operates to meet the equipment standards. Weigh the need for water.
