Sludge Dewatering Machine Rotary Drum Type Precision Filter For Wastewater Treatment
The Use Of Rotary Drum Precision Filter
Drum type precision filter is a simple mechanical filtration method. It is suitable for the separation of micro-suspended solids in liquids, mainly phytoplankton, zooplankton and organic residues, to achieve the purpose of purifying liquids or recovering useful suspended solids. The fundamental difference between microfiltration and other filtration methods is that the total pore size of the stainless steel mesh or microfilter is very small and thin. Such filters feature relatively low hydraulic resistance and large flow rates, and the retained suspended solids tend to be smaller in size than the pores on these filters. Drum type precision filter is a water treatment equipment based on this principle.
Drum type precision filter is an economical water treatment equipment. It can be used for industrial water filtration, circulating cooling water filtration, wastewater purification, sewage treatment and other raw water filtration in water plants, power plants, chemical plants, textile printing and dyeing, paper mills, etc. A typical example of the use of rotary drum precision filters to recover useful suspended solids in liquids is pulp (fiber) recovery of papermaking white liquor. The liquor can be recycled and used after recovery and purification to meet the emission standard.

Equipment Advantage
A. The filter screen is made of 316L stainless steel, which is non-toxic, non-polluting, no chemical cleaning, and has a service life of not less than 10 years. The filter screen is woven from 316L stainless steel through fibrillation technology, and then seamlessly welded and fixed on the stainless steel rib with advanced spot welding technology.
B. The filter is easy to replace. Each set of equipment consists of 8 independent arc segments, each segment can be easily disassembled and assembled, so there is no need for special tools and equipment when replacing the filter.
C. Backwashing consumes less water. The backwash water volume of a single unit is 60m3/d, the backwash water volume and the system sewage volume are small, which reduces the burden of subsequent treatment of polluted wastewater.
D. The treatment effect is good. The stainless steel filter screen is used, and the filter pore size of the filter screen is 10~200µm, and different pore sizes can be selected according to the requirements of the effluent. So as to ensure the water quality and water stability.
E. Strong shock load resistance. The equipment can operate normally when the influent SS is not higher than 40mg/L.
F. Filtration can run continuously. Continuous filtration is possible while backwashing.
G. Small head loss. not more than 0.3m.
H. Low energy consumption for operation. The main drive motor and the backwash pump motor have low power and operate intermittently. The operating cost is about 0.002 yuan/ton of water per day.
I. Run fully automated controls. Filtration, backwashing, etc. are all controlled by the program, and are equipped with multiple protections, and no special personnel are required for daily operation and management.
J. Small footprint. In the case of the same amount of treated water, the footprint of the filtration equipment is much smaller than that of other filtration process equipment.
