The reverse osmosis water treatment equipment is divided into two parts, one is the pretreatment commissioning, and the other is the commissioning of the reverse osmosis host. The pretreatment is mainly the positive and negative washing of quartz sand and activated carbon to wash away the fine sand,...

As a deep filtration means, the surface of reverse osmosis membrane element will inevitably remain colloids, microorganisms, impurity particles and insoluble salts on its surface. Therefore, once put into use, the reverse osmosis devices used in many fields will eventually need to be cleaned, but th...

2021 is both a "resource utilization year" and a "low-carbon development year" for the sewage treatment industry During the "14th five year plan" period, sewage treatment and resource utilization were steadily promoted. The county's sewage treatment, urban sludge disposal and reclaimed water us...

Standard recovery rate, actual recovery rate and system recovery rate (1) Standard recovery rate of membrane element: the recovery rate adopted by the manufacturer under standard conditions. (the recovery rate of brackish water is 15%, and that of seawater is 10%) Actual recovery rate of membrane ...

I What is a water hammer? Water hammer is called water hammer because of the inertia of pressure water flow when the power is suddenly cut off or the valve is closed too fast, which produces water flow shock wave, just like a hammer hitting. The water hammer of pump station includes starting water...

Air floatation machine is a water treatment equipment in which a large number of micro bubbles are generated in the water by the dissolved air system, so that the air is attached to the suspended solids particles in the form of highly dispersed micro bubbles, resulting in a state that the density is...

1. Activated carbon Water purification activated carbon is generally columnar particles with large specific surface area, developed micropores, high mechanical strength, fast adsorption speed, high degree of purification, not easy to de powder and long service life. Water purification activated car...

Guided reading 2021 is both a "resource utilization year" and a "low-carbon development year" for the sewage treatment industry During the "14th five year plan" period, sewage treatment and resource utilization were steadily promoted. The county's sewage treatment, urban sludge disposal and re...

1、 Working principle and process flow Membrane technology is used as the core filter material, supplemented by pretreatment or other equipment to achieve the purpose of purification. *Process flow of secondary reverse osmosis purified water: Raw water - quartz sand filter - activated carbon filte...

Polishing resin is generally used at the end of ultrapure water treatment system to ensure that the effluent quality of the system can maintain the water standard. Generally, the resistivity of effluent quality can reach more than 18.25m Ω, and has certain control ability for TOC and SiO2. Goo...

A coal chemical enterprise uses coal as raw material to produce methanol from syngas in coal gasification process, and methanol is then made into olefins. A large amount of chemical production wastewater is produced in its production process. After advanced treatment in the plant, a large amount of ...
