Reverse osmosis filter & reverse osmosis pretreatment
Pretreatment often consists of quartz sand filter device, activated carbon filter device, and precision filter device. The main purpose is to remove sediment, rust, colloidal substances, and suspended solids contained in raw water. , pigments, odors, biochemical organic matter, and reduce the residual ammonia value of water and pesticide pollution and other harmful substances. If the content of calcium and magnesium ions in the raw water is high, a water softening device needs to be added. The main purpose is to protect the reverse osmosis membrane of the later stage from damage by large particles, thereby extending the service life of the reverse osmosis membrane.
Reverse osmosis equipment is a water treatment system organized around a reverse osmosis membrane. A complete reverse osmosis system consists of a pretreatment part, a reverse osmosis host (membrane filtration part), a post-treatment part and system cleaning. parts together.
The post-processing part is mainly to further process the pure water produced by the reverse osmosis main machine. If the subsequent process is connected to ion exchange or electrodeionization (D) equipment, industrial ultrapure water can be produced. If it is When used in civil direct drinking water technology, it is often connected to a post-sterilization device, such as an ultraviolet germicidal lamp or an ozone generator, so that the water can be directly drank.
Reverse osmosis pretreatment mechanical filter
Mechanical filter is used to reduce the turbidity of water. It can be used as a pretreatment equipment for water or as a separate ordinary filtration equipment for water quality requirements that are not too high. place. The principle of the mechanical filter is to use one or several filter media to pass the raw liquid through the media under a certain pressure to remove suspended solids, organic matter, colloidal particles, microorganisms, chlorine, odors and some heavy metal ions in the water. Purify the water. Mainly used to reduce turbidity, suspended solids, viscous and non-viscous colloidal substances in water bodies. The fillers inside are generally: quartz sand, anthracite particles, porous ceramics, manganese sand, etc. Generally, when the turbidity of the raw water is greater than that and the suspended solids content is greater than mg/kg, quartz sand is generally used as the filter material. When the iron and manganese content in the water body is When it is larger than .㎎, the filter material can be changed to manganese sand, which can effectively remove excessive iron and manganese ions in the water. Users can choose to use it according to the actual situation
Mechanical filter, also called pressure filter, is an important part of the pretreatment and water purification system for pure water preparation. The material is steel lined or stainless steel. According to the filter medium They are divided into multi-media filters, activated carbon filters, and manganese sand filters. They can be used in combination or alone according to the actual situation. Its function is to filter out suspended solids, mechanical impurities, organic matter, etc., thereby improving the clarity of water. The medium of the activated carbon filter is activated carbon, which adsorbs and removes pigments, organic matter, residual chlorine, colloids, pigments, microorganisms, etc. in the water. The medium of the manganese sand filter is manganese sand, which mainly removes divalent iron ions in the water.

Reverse osmosis pretreatment activated carbon filter
The activated carbon filter is a steel cylindrical container. There are upper and lower water distribution devices inside the device, and corresponding pipes, valves and instruments outside the device. Fill the activated carbon granules into the container to form an activated carbon filter. During operation, the water to be treated enters from the upper part of the filter and passes through the activated carbon filter layer from top to bottom. The adsorption performance of activated carbon is used to remove harmful substances in the water, such as organic matter, colloids, microorganisms, oils, residual chlorine and odors, etc. Adsorbed on the surface of activated carbon and removed.
