1、 Equipment name: automatic hollow fiber ultrafiltration water treatment equipment

2、 Specification and model: hdnuf-6000l

3、 Equipment brand: Wenzhou Haineng wzhdn

4、 Product Description:

Application of core technology of hollow fiber ultrafiltration membrane in water treatment. Hollow fiber ultrafiltration membrane is a kind of advanced and mature membrane element, which has remarkable effect in water treatment application. The water quality of the effluent can completely meet the national limited discharge standard, and many treated water quality can be used in the reuse of reclaimed water. The reason why the reuse rate of the water treated by hollow fiber ultrafiltration membrane is relatively high is that its outer diameter is only 0.5-2.0mm, and its inner diameter is only 0.3-1.4 Mm, and the wall is covered with micropores, which can retain thousands to hundreds of thousands of molecular weight. Therefore, it has a strong ability of wastewater interception, and the enterprises with large water consumption can make full use of water resources, save energy and reduce emissions, and reduce the production cost of enterprises. Hollow fiber ultrafiltration membrane is an advanced polymer separation membrane.

5、 Equipment preparation:

1. Mechanical filter:

It is mainly used to remove rust, sediment, algae, suspended solids and other impurities in the water, reduce the turbidity of the water, make the turbidity of the water less than 0.5ntu, CODMn less than 1.5mg/l, iron content less than 0.05mg/l, SDI ≤ 5. The control valve can be used for back washing and forward washing at any time to wash off the dirt on its surface, prevent it from blocking and restore its filtering capacity.

2. Activated carbon filter:

Activated carbon has a very strong adsorption and filtration performance, and has a strong adsorption effect on residual chlorine, heterochromatic, peculiar smell, organic matters, etc. in water. As the reverse osmosis membrane is very sensitive to residual chlorine and organics, it is necessary to configure activated carbon to absorb residual chlorine and organics, so that the residual chlorine in the outlet water is ≤ 0.1mg/l, SDI ≤ 4, the first can meet the water supply requirements of the reverse osmosis membrane. Second, it can greatly improve the original taste of the source water. It can be backwashed at any time through multiple control valves or steam operated butterfly valves to wash away the colloid and other pollutants on the surface, prevent the surface of the activated carbon from being surrounded by impurities, prevent it from blocking, and restore its treatment capacity.

3. Security filter:

After pretreatment, a safety filter is arranged in front of the high-pressure pump to prevent the impurity particles larger than 1um from entering the high-pressure pump and damaging the high-pressure pump and reverse osmosis membrane. The PP filter element (with framework and good strength) is loose outside and tight inside, and the water is filtered from the outside to the inside, which can prolong the time when the filter element is blocked. The upper part has an exhaust valve, which can prevent air from entering the pump and damaging the pump. The lower part has a drain valve, which can discharge the retained impurities at any time.

4. Hollow ultrafiltration device:

Ultrafiltration technology is a mature technology in the world to produce mineral water, and it is also a water treatment technology widely used in the market and with a wide range of applications. It can precisely filter bacteria, viruses and various floating substances in the water, with low working pressure, large water yield, large water flow, low cost and easy maintenance. The design of automatic washing device can extend its service life.

6、 Component features:
◇ The stainless steel clamp structure has stronger pressure bearing capacity, effectively preventing the burst and water leakage caused by the instantaneous high pressure and impact of the medium-sized ultrafiltration system;

◇ The shell is made of UPVC material with high toughness. The material has good aging resistance, acid and alkali resistance and chemical stability, and is suitable for a wide range of working conditions.

◇Adopt unique 7-sector silk loading technology to make the water distribution in the shell uniform;

◇ the water inlet and outlet are all the interfaces of national standard DN32, and the four end caps of loose knot thread are of the same size and specification, which is convenient for installation and maintenance;

◇ The effective area of the membrane is large and the water flux is large.

◇ Electronic industry: semiconductor industry ultra pure water equipment, integrated circuit cleaning water treatment equipment;

◇ Pharmaceutical industry: medical pure water, drug concentration and separation;

◇ Water treatment engineering: purified water preparation, drinking water purification, reverse osmosis device;

◇ Food industry: juice concentration and clarification, protein concentration and separation;

◇ Wastewater treatment engineering: industrial wastewater, municipal wastewater treatment and reuse, etc.
8、 Equipment advantages:

1. In the membrane bioreactor, biological treatment and filtration disinfection are carried out simultaneously, so the effluent quality is good;

2. Compact equipment, less land occupation;

3. In the reactor, high concentration of microorganism can be obtained, and the treatment load can be increased;

4. The macromolecular organic compounds which are difficult to degrade in a short time can be retained;

5. The complete separation of HRT and sludge age makes the biological treatment process easy to control and has higher reliability and flexibility.
