Main processes of purified water treatment (I)

1. Purification filter

Poor filter: suitable for mechanical filtration, removal of suspended solids in water, colloids, turbidity, color, odor, etc. The main filtration methods include purification tanks, rapid filters, sand filters, sand filters, multi-media filters, activated carbon filters, disc filters, fiber filters, etc. Water Purifier

2. Filtering.

Precision filter: a filter membrane made of special materials with high filtration accuracy. The common ones are microfilters and filters.Water Purifier

3 ultrafiltration

Ultrafiltration: This is a type of membrane filtration that removes large molecules, colloids, fine bacteria, etc. High filtration accuracy, usually achieved through ultrafiltration membranes. Ultrafiltration membranes do not remove ions from water, which means they do not have a desalination effect. Suitable for anti-seepage pretreatment * or precise treatment after reflux * and can also be used separately. Ultrafiltration is a filtration process driven by the tangential flow and pressure of a fluid, separating particles according to their molecular size. The ultrafiltration equipment is in the range of 0.002-0.1 microns. Soluble substances and substances with pore sizes smaller than the membrane can be concentrated into permeate through the filtration membrane, while substances that do not pass through the filtration membrane are concentrated into effluent. Therefore, the production water contains water, dissolved solids, and small molecular weight substances, while colloids, suspended particles, and high molecular weight particles such as organic matter, fine bacteria, viral agents, and protozoa will be filtered and removed.Water Purifier

4. Reverse osmosis * transparency

Reverse osmosis permeability: Reverse osmosis, abbreviated as RO, is a membrane separation technology developed in the 1960s. Its basis is that raw water passes through a reverse osmosis membrane under high pressure, and the solvent in the water diffuses from high concentration to low concentration. In order to achieve the purpose of separation, purification, and concentration, it is called reverse osmosis seepage because it is opposite to the direction of natural seepage. Anti permeability can remove small bacteria, pathogenic toxins, colloids, organic matter, and over 98% soluble salts from water. This method has the characteristics of low operating cost, simple operation, high degree of automation, and stable water quality. Compared with other traditional water treatment methods, it has obvious advantages and is widely used in various industries of water treatment.
