Applicant of Waste Water Precise Filter
A. Cooling
B. Recycled Waste Water
The Intake Water Quality SS<=80 mg/l, &
The Effluent Water Quality SS<=20 mg/l,
C. For Advanced Deep Treatment Of Sewage by following fields after Conventional Activated Sludge Method, Delayed Aeration Method, SBR System, Oxidation Ditch System, Drip Filter System & Oxidation Pond System:
1. Removal of The Total Suspended Solid
2. Combined with Dosing Agent To Remove Phosphorus;
3. Can Remove Heavy Metals
D. The Cloth Turntable Filter is used to filter the effluent from the activated sludge final settling tank.
Intake Water Quality: SS: 30 mg/l (maximum 80-100 mg/L)
Effluent Water Quality: SS: <5 mg / l turbidity <= 2NTU.
The Actual Running Water Is Better,The General Effluent Turbidity Is Around 1
Working Principle of the Turntable Disc Filter
Its Operating State Is Divided Into Two Relatively Independent & Simultaneous Processes Of Raw Water Filtration & Back-washing. Both Are Done In Different Locations On The Same Filter.
-Raw Water Filtration:
Filtration: Sewage Enter The Filter Tank Via Its Gravity Flow by Fully Going Through the Immersed Rotating Disc to Generate A Water Raft which makes The Filter Tank Water Uniform & the Inlet Water water With Low Disturbance. The Sewage Is Filtered Through a Filter Cloth & the Filtrate Is Collected Through a Hollow Tube & Discharged Through a Water Effluent. Filtration is Still In Progress During The Cleaning Process. Therefore, The Filtration Is Continuous Throughout The Operation....
The equipment is in a static state during filtration, which is beneficial to the sedimentation of the bottom of the sludge.
B. Back-washing
As the sludge Accumulates On The Filter Cloth to Generate Cloth Resistance Gradually by Viewing the Pressure Sensor Changed ,which will give signalto liquid level of the PLC to start The Backwash Pump and cleaning process. The Backwash Time & Period Can Be Adjusted.The Filter Can Be Continuously Filtered During Cleaning.
C. The Sludge Discharge
As The Sludge Accumulates On The Filter Cloth to Increase the Resistance of The Filter Cloth, Thus to Increase Its Pool Water Level. The Sedimentation at the Bucket-Shaped Bottom Of The Sludge Tank Reduces The Amount Of Sludge On The Filter Cloth, Which Can Extend The Filtration Time & Reduce The Amount Of Backwash Water. After a Set Period Of Time, the PLC Starts The Sludge Pump & Returns sludge to Its Drainage System through Its Bottom Perforated Pipe. The Duration Of Mud Discharge Can Be Adjusted. In addition, when The Treatment System In Front Of The Filter Fails, The Mud Discharge System Can Be Activated To Play The Role Of Emptying The Filter.
