Sanitary Butterfly Valves Used in Raw Water Industry

by Adamantvalves

Sanitary butterfly valves have many advantages such as simple structure, small size, light weight, easy installation, etc. As a part used to realize pipeline system on and off and flow control, sanitary butterfly valves are widely used in many fields, such as petroleum, chemical engineering, metallurgy, and hydropower. The applications of sanitary butterfly valves in raw water tank equipment are introduced as follows.

Raw water tank

The raw water tank of the sanitary butterfly is used to precipitate large sediment particles and other precipitable substances in the water and can cushion the impact of unstable water pressure in the raw water pipe on the water treatment system.

Raw water pump

The raw water pump of the sanitary butterfly valve is used for constant system water supply pressure and stable water supply.

Multi-media filter

The main purpose of the filter layer is to remove sediment, rust, colloidal material, suspended matter and other particles in raw water above 20um. Manual valve control or automatic controller can be used for a series of operations such as backflush and normal flush. It can guarantee the quality of water production and extend the service life of the equipment.

Activated carbon filter

The system adopts the shell activated carbon filter, which can not only absorb electrolyte ions but also carry out ion exchange adsorption. In addition, as the adsorption increases the concentration of the surface being absorbed and copied, it also acts as a catalyst to remove the pigments, odors, large amounts of biochemical organics, reduce residual chlorine and pesticide pollutants and remove trihalides (THM) and other pollutants in the water. Furthermore, the equipment has a self-maintaining system and running costs are low.

Precision filter

The precision filter is used to remove suspended material, non-curved grain, and colloid, etc. in the water, so that subsequent equipment such as RO system can operate more safely and reliably. The filter core is 5um molten spray filter core, and the purpose is to remove the impurities larger than 5um left out by the superior filter unit, so as to prevent it from entering the surface of the membrane damaged by reverse osmosis device, and the desalination performance of the membrane is thus maintained.

Reverse Osmosis System

The reverse osmosis device is used to separate the solvent (usually water) from the solvent in the solution by the reverse osmosis membrane (or semi-permeable membrane), and this process is called reverse osmosis because it is opposite to natural osmosis. Reverse osmosis method can adapt to all kinds of raw water with salt content, especially in water treatment engineering with high salt content, which can obtain good technical and economic benefits. Besides, the reverse osmosis equipment removes most bacteria, colloid, and organics with large molecular weight while removing salt.
