1.It is one of the most advanced filtering devices in the world.The filter uses fibrous filter cloth as filter medium to replace the traditional sand filter.

2.Rotary Disc Filters adopts long staple fiber filter cloth, which has high filtration precision and is easy to backwash. The fuselage of Rotary Disc Filters is made of corrosion-resistant SUS304 stainless steel material. It is suitable for long-term use in various kinds of sewage. The Rotary Disc Filters is mainly used for cooling circulation water treatment and deep treatment of waste water after reuse.

3.Rotary Disc Filters is the third generation of new filter equipment developed by our company. It has good treatment effect, high water quality, stable operation of equipment and set up perfect after-sale service.

Application

The Rotary Disc Filters is mainly used for cooling circulation water treatment and deep treatment of waste water after reuse.

Equipment characteristics

1. Our Rotary Disc Filters used special technology. It has strong impact resistance and fiber will not fall off. The strength of filter cloth is high, and wet strength is basically the same as dry strength.

2. Good elasticity and almost complete recovery after elongation.

3. Fiber surface smooth, dirt easy to fall off, corrosion resistance, no moldy.

4. The filtration precision is high, the microfiltration diameter is 5-20um, and it can be selected according to need.

Advantage

1. The effluent of the fiber filter cloth is good and stable. Rotary Disc Filters is used as a filter cloth to replace the sand filter material of the traditional filter. The pore size of the filter cloth is very small, and the particle size of a few microns (m) can be intercepted, so the water quality and the stability of the effluent are better than the granular filter. However, the water quality of the conventional filter before irrigation is poor. After rinsing, the residual washing water in the filter layer will affect the effluent. In addition, the amount of water filtered varies with resistance.

2. Rotary Disc Filters is novel in design and resistant to impact loading. Rotary Disc Filters is equivalent to the combination of filter and sedimentation tank, which has the function of sludge discharge. Large granular sludge is directly precipitated to the bottom of bucket shaped tank, and it will not clog up filter cloth. That is not like ordinary filter: all suspended solids (SS) must pass through filter media. Therefore, the filtration cycle is long, the cleaning interval is long, and the hydraulic load and the sludge load are far greater than the conventional sand filter. The SS load is 1.5 times that of the ordinary sand filter, and the filter speed is 50% higher than that of the ordinary filter. Therefore, the filter cloth rotary disc filter is more resistant to high suspended solids concentration and large particle suspension.

3. Rotary Disc Filters is simple and compact, with fewer ancillary equipment, and low investment in the whole filtration system. Rotary Disc Filters can be filtered continuously when the filter is cleaned. The sand filter can not be filtered continuously during backwashing. In order to ensure continuity, it is necessary to set up an intermediate storage tank in front of the sand filter or alternatively work with multiple filters. The Rotary Disc Filters uses a small pump to vacuum suction and filter after water automatically cleaning, eliminating the need for many traditional filter backwashing pools, water towers, etc. Because of the large backwash strength and the backwash of gas and water, the traditional filter needs not only the large power pumps, blowers, but also two sets of larger diameter pipe valves. The whole system is many and miscellaneous, and the investment is high. The automatic control system is extremely complex.

4. The equipment idling rate of the Rotary Disc Filters is low, and the total installed power is low. Because the filter cloth is thinner, it is very easy to rinse, and the cleaning is very efficient. When cleaning, the area of the filter plate is only 1% of the whole filter area. Cleaning is characterized by frequent but short cleaning times (1/60-120 minutes, 1 minutes/times). The total amount of water is less. However, there are many equipments for gas and water backwashing pumps and blowers in traditional filters, automatic valves are large and large, and the power is large, and the idle rate is high.

5. The operation of the Rotary Disc Filters is automatic, so operation and maintenance are simple and convenient. The filtration process is controlled by a computer, and the interval time and duration of the negative pressure suction cleaning process and the sludge discharge process can be adjusted. Basically, there is no need to maintain management. The overhaul of Rotary Disc Filters is small. Rotary Disc Filters is less pump and motor intermittently, filter cloth wear small, easy to replace filter cloth, if the filter cloth is blocked for some reason, the filter cloth can be replaced easily. For sand filter, if the filter material is blocked, a great amount of cleaning work will be required. It is very difficult to replace the filter material by sand filtration.

6. The head loss of Rotary Disc Filters is much smaller than that of sand filter. Filter cloth rotary disc filter is generally 0.2m, while sand filter head loss is generally 1.5m. The head loss of sand filter tank is higher than 5m, and the energy loss is large and the operation cost is increased.

8. The area of the Rotary Disc Filters is much smaller than that of other filters. Because of the design of the air pipe in the vertical of the filter, the small area can guarantee the large area of the filter, thus reducing pond volume, reducing the material and work, and reducing the cost of the project significantly. The daily processing capacity of 10 thousand tons of filter is less than 20 square meters and the height is 3.3m. For technological transformation, we can solve the problem of insufficient space.

8. Rotary Disc Filters is easier to install than filter material filter. After on-site connection of pipe fittings and electrical equipment, it can be put into operation. And filter media often need to filter material installation.

9. The design cycle and construction period of the Rotary Disc Filters are short. The filter cloth turntable filter is integral and can be shipped as a whole. The design and construction are convenient and fast, and the expansion is easy.

10. Rotary Disc Filters has low requirement for resistance to ground base and less investment in equipment foundation.
