The ultrafiltration device is introduced

A, ultrafiltration membrane device is introduced

ultrafiltration technology is a kind of widely used in water purification, solution separation, enrichment, and extract useful substances from waste water, waste water purification reuse in the field of high and new technology. Characteristics is to use the process is simple, without heating, energy saving, low voltage operation, cover an area of an area small.

in the ultrafiltration membrane ultrafiltration technology is one of the most mature and advanced technology. Hollow fiber diameter: 0. 5 - 2. 0 mm, inside diameter: 0. 3 - 1. 4 mm, be full of microporous hollow fiber tube walls aperture to intercept molecular weight of the material expression, intercept molecular weight can be up to several thousand to tens of thousands of. Raw water in the hollow fiber outer or inner cavity pressure flow, constitute the external pressure and internal pressure type, respectively. Ultrafiltration is a dynamic filtration process, trapped material can with concentrated small ruled out, not blocking the membrane surface, can run continuously for a long time. Ultrafiltration membrane is one of the earliest development of polymer separation membrane.

2, daily maintenance

ultrafiltration membrane ultrafiltration membrane can intercept bacteria, but can not kill bacteria, ultrafiltration membrane withholding rate again good also cannot guarantee a clean area for a long time is not long, a bacteria, bacteria can thrive. Directly affect the through water, such as some mineral water products appear in the translucent filaments white flocculent u team, the main is the u bacteria contamination caused by system. Therefore, must be regularly to the turnover of environment and filtering system for regular sterilization, sterilization operation cycle for supply of raw water quality, for the city of ordinary tap water, 7 ~ 10 days in summer, winter 30 ~ 40 days, 20 ~ 30 days age season. Surface water as water supply, the sterilization cycle shorter. Sterilization drug available from 500 to 1000 mg/L sodium hypochlorite solution or 1% hydrogen peroxide solution circulation flow or soak for about half an hour.

ultrafiltration components to should take put down gently, and pay attention to protect, due to the ultrafiltration components are precision equipment, so be careful when using the installation, should take put down gently, nor bad. Component if disable, want to rinse off with clear water after the first, adding 0. 5% formalin disinfection sterilization, and sealed. Components such as winter antifreeze processing, otherwise the component may be scrapped.

3, ultrafiltration membrane application:

1, pure water and ultrapure water equipment;

2 no hot raw water equipment, medical asepsis,

3, beverages, drinking water, industrial water purification,

4, industrial separation, enrichment, purification,

5, industrial wastewater treatment, electrophoresis paint, electroplating of oily wastewater treatment.
