Application of membrane Separation Technology in recovery of Organic waste Gas and solvent dehydration

Application of membrane Separation Technology in recovery of Organic waste Gas and solvent dehydration

1. Raw water tank (optional)

Store raw water for sedimentation of large sediment particles and other precipitable substances in water. At the same time, it buffers the impact of water pressure instability on the water treatment system in the raw water pipe. (such as pressure sensing reaction caused by low or too high water pressure)

2. Original water pump

Constant system water supply pressure, stable water supply.

3. Multi-media filter

The filter with multiple filtration layers is mainly used to remove the sediment, rust, colloidal substances, suspended solids and other particles containing more than 20um in the raw water. It can be backwashed by manual valve control or fully automatic controller. Flush and other operations. Ensure the water quality of the equipment and extend the service life of the equipment.

4. Activated carbon filter

The system adopts a shell-shell activated carbon filter. The activated carbon can not only adsorb electrolyte ions, but also perform ion exchange adsorption. The adsorption of activated carbon can also reduce the oxygen consumption (COD) of potassium permanganate from 15mg/L (O2) to 2-7mg/L (O2). In addition, due to the adsorption, the concentration of adsorbed replication on the surface increases. It acts as a catalyst, removes pigments, odors, large amounts of biochemical organic matter, reduces the residual chlorine value of water, and removes trihalides (THM) and other contaminants from water. Manual valve control or fully automatic controller can be used for backwashing, flushing and other operations. Ensure the water quality of the equipment and extend the service life of the equipment. At the same time, the equipment has a self-maintenance system and the operating costs are low.

5. Security Overthinker

The use of a security filter to remove suspended solids, non-straight particles and colloids in the influent water makes the subsequent equipment such as the ultrafiltration system safer and more reliable. The filter element is a 5um meltblown filter element, the purpose is to prevent the upper filter unit, and the impurities that are missing more than 5um are removed. Prevents damage to the surface of the membrane by entering the ultrafiltration unit, thereby damaging the performance of the membrane

6. Ultrafiltration device

UltraFiltration (UF) is the solution under pressure, the solvent and part of the low molecular weight solute pass through the micropores on the membrane to the other side of the membrane, while the polymer solute or other emulsified micelles are trapped to achieve the solution. The purpose of separation. Its separation mechanism is mainly based on physical screening. In the ultrafiltration separation, after a certain pressure is applied to the liquid, the polymer material and the colloidal substance are adsorbed by the membrane surface and the micropores once, and the pores are blocked and intercepted, and the mechanical surface of the membrane surface is mechanically sieved. The ultrafiltration membrane blocks while water and low molecular substances pass through the membrane. Mineral water, who spring water equipment can use the ultrafiltration device to effectively remove macromolecules such as colloids, chemical organic matter, heavy metals and bacteria in water, and retain beneficial trace elements in water.
