Water treatment UF system 25TPH for filling machine water purification. Low energy high recovery rate with cross flow type UF membrane.

It is a purification, separation or concentration of semipermeable membrane in separation techniques for solution. After more than 20 years rapid development, it has become one of the widest techniques in separation field. It widely uses in food and beverage, chemical electron, biological construction for environmental protection, etc.

Ultra filtration membrane is used to remove suspended solids, colloids, microorganism, bacteria,virus and macro molecule organism from the raw water.It has good function of color removing, oil removing, turbidity removing, COD and BOD removing. UF technology can be adopted under condition of normal temperature and  low pressure with low energy consumption

This system use Canpure outside-in ultrafiltration membrane modules, the material for the membrane is PVDF, it can cleaned thoroughly by strong oxidant and is good at chemical resistance, mechanical strength and longer life time. This UF system is designed to treat well water with high suspended solids, microorganism, bacteria and virus. Each UF membrane have very good function to remove it. Ans the output water is for washing water supply.

1. Brief introduction of Water treatment UF system

Technical Information for UF water treatment plant
UF water treatment plant Ultra filtration (UF) is a separation process by using membranes with pore sizes in the range of 0.1 to 0.001 micron. Typically, ultra filtration will remove high molecular-weight substances, colloidal materials, and organic and inorganic polymeric molecules. Low molecular-weight organics and ions such as sodium, calcium, magnesium chloride, and sulfate are not removed. Because only high-molecular weight species are removed, the osmotic pressure differential across the membrane surface is negligible. Low applied pressures are therefore sufficient to achieve high flux rates from an ultra filtration membrane.

Membrane Materials
A variety of materials have been used for commercial ultra filtration membranes, but poly sulfone (PS), PAN, PP and PVC are the most common. Recently thin-film composite ultra filtration membranes have been marketed. For high purity water applications the membrane module materials must be compatible with chemicals such as hydrogen peroxide used in sanitizing the membranes on a periodic basis.

Performance of Ultra filtration Systems
In high purity water systems, ultra filtration is slowly replacing the traditional 0.2-micron cartridge filters. In Japan, practically all of the semiconductor industry follows this practice. An ultra filtration membrane with a molecular-weight cutoff of 10,000 has a nominal pore size of 0.003 micron. When an ultra filtration membrane is used instead of a 0.2-micron cartridge filter, particle removal efficiency is greatly improved. In addition, ultra filtration membranes are not susceptible to the problem of bacteria growing through them, as is the case with 0.2-micron filters.
As the requirements for the quality of high purity water become more stringent, we can expect to see an increasing use of ultra filtration as a final filter.

8.Technical route

Raw water was firstly pressurized by raw pump and then filled into sediment filter to remove the substances over 5um. Then feed into ultra filtration system for treatment, concentrate water was discharged or recovered, the permeate water feed into the UF tank. After operation for a while, the equipment should be chemical cleaned. Refer to the Appendix.
