Unique design and advantages of fiber rotary disc filter

 (1) The outlet water quality is good and the impact load resistance is high

The fiber rotary disc filter has a good interception effect. When the inlet water SS is not greater than 20mg/l, the outlet water SS can be less than 5mg/l. The inlet weir is uniquely designed to dissipate energy and prevent disturbance. Filtration and backwashing are performed at the same time. Only 1% of the area of a single disk in the pool is undergoing backwashing at an instant. Filtration is continuous and has strong impact load resistance.

(2) Small footprint

What is different from the traditional depth filtration unit is that the water flow in the traditional filtration equipment generally flows from top to bottom, or from bottom to top, which is a planar direction filtration. The fiber turntable microfiltration unit raises the filter surface vertically, and the water flow flows from left to right. , so many filter surfaces can be arranged side by side, which can reduce the floor space while ensuring that the filter area is large enough. In addition, the equipment is simple and compact, with few ancillary equipment. Depending on the layout, the ancillary equipment only takes up a small amount of space.

(3) The equipment idle rate is low and the final assembly power is low

All filter discs are almost always in filtering state, and the equipment idle rate is low. The entire filtration device only requires electricity for the drive motor, backwash pump and electric valve. The drive motor power is only 0.55KW-0.75KW, and the backwash pump power is only 2.2KW. The total installed power is very low. For example, for a processing capacity of 4 The total installed power of the fiber turntable microfiltration machine of 10,000 m3/d is about 10KW. This advantage is particularly prominent for renovation projects. For sewage treatment plants, there is no need to expand capacity in terms of electricity consumption.

(4) The amount of backwash water is small and has little impact on the previous treatment process.

The fiber turntable microfiltration machine requires a small amount of water, and the ratio to the treated water volume is ≤1%. Under actual engineering operation conditions, the backwash interval is generally 2h, and the flushing time of each filter plate is 1-2mim. Therefore, the amount of backwash water can be returned to the pre-treatment system relatively uniformly without affecting the pre-treatment process.

(5) Clean thoroughly, no need to add chlorine in advance

The existing filter cloth structure and backwash frequency and intensity make the operation of this filtration equipment basically unaffected by algae growth problems. First of all, the structure of the filter cloth is a large pore support layer and a fiber wool layer. During reverse suction, the fiber wool will stand up completely at the reverse suction port. The cleaning is relatively thorough and it is difficult for residues to accumulate. Thirdly, the backwash frequency of this filter equipment is generally 60 minutes, which is relatively intensive, and the flushing intensity is relatively high, which is 333l/m2﹒ s, making it very difficult for algae to grow, so there is no need to pre-add chlorine before the filter

(6) Operation automation

The whole process is controlled by computer, and the time interval and process duration of the backwash process and mud discharge process can be controlled according to the liquid level or time.

(7) Simple and convenient maintenance

There may still be large foreign objects (such as plastic bags, cloth strips, fibers) in the effluent after sedimentation of sewage treatment, that is, in the water before filtration. Their impact and damage to the filtration system can be ignored, and the corresponding maintenance problems will not be affected. Large, it is related to operational safety and stability. The form of fiber turntable filter filter is outside in and inside out, that is, the sewage enters the filter first, and the filtered sewage enters the central pipe. In this way, even if there are large floating objects in the water before filtering, it will have a great impact on the operation of the filter few.

The fiber turntable microfilter has less mechanical equipment, and the pump and motor run intermittently. The filter disc is stationary during filtration, and the pump or motor only runs during backwashing or mud discharge. The filter cloth wears less, and even if there is abnormal damage, the filter disc is easy to replace. Each segment of the filter disc can be removed independently, and it only takes 10 minutes to replace one disc.

• (8)An accident in the pre-filtration treatment system will have less impact on the filter and will recover quickly.

During the operation of the project, some accidents will inevitably occur in the biochemical treatment system before filtration, causing the sludge in the biochemical tank to be discharged into the filter. For the fiber turntable filter, the sludge contamination is only on the outside of the filter disc, but there is no contamination on the inside of the filter disc that contacts the filtered water, so the impact is small, and the sludge in the filter can be quickly removed through the sludge discharge pipe. Recovery is faster. 

(9) Short design cycle and construction cycle

The fiber turntable microfiltration machine is modular in design, has fewer external interfaces, and has a short design cycle. It is easy to install and the construction period is short.
