High Efficiency Lamella Clarifier For Sludge Sedimentation
The main technology of high-efficiency lamella clarifier is carrier flocculation technology, which is a rapid precipitation technology, which is characterized by the addition of high-efficiency insoluble media particles (such as fine sand) during the coagulation stage....
Send InquiryHigh Efficiency Lamella Clarifier for Sludge Sedimentation has a very compact design. It integrates coagulation tank, flocculation tank, lamella clarifier and sludge concentration. The high-efficiency lamella clarifier is suitable for drinking water production, sewage treatment, industrial wastewater treatment and sludge treatment.
Product Features
The definition of carrier flocculation is a physical and chemical treatment process that uses continuous circulation of media particles and various chemical agents to enhance the adsorption of flocs to improve the sedimentation performance of suspended matter in water. Its working principle is to first add a coagulant (such as ferric sulfate) to the water to destabilize the suspended matter and colloidal particles in the water, and then add a polymer coagulant and a carrier particle with a higher density to make the destabilized Impurity particles use carriers as flocculation nuclei, through the bridging adsorption of polymer chains and the trapping effect of sedimentary nets of micro-sand particles, quickly generate dense-density alum flowers, thus greatly reducing the settling time and improving the processing capacity of the sedimentation tank, and Effectively deal with high impact loads.
Product advantages
Efficient lamella clarifier technology has been used for decades and its technology has been proven to be effective and reliable, including applications in the following special cases that are generally considered difficult to handle: ①For example, river water will cause sudden turbidity due to flooding Degree and suspended matter concentration increase; ② Flocculation caused by low temperature is difficult; ③ Slight flocculation caused by high color and low turbidity in raw water; ④ Raw water with strong algae growth
Unlike the sludge bed process, the performance of the efficient lamella clarifier process will not be affected by rapid changes in temperature, which has been proven in actual operating facilities.
Because of the suspension of the returning sludge, the efficient lamella clarifier process can produce a stable sedimentation effect even when the influent water quality changes very drastically. For example, the turbidity of raw water in the Mame River is as high as 400 NTU during flooding, and the effluent turbidity after processing is less than 1 NTU; in Selangor, Malaysia, when the influent turbidity changes from 500 NTU to 1500 NTU within 2 hours, After the water turbidity is maintained at 2 ~ 3 NTU.
Using the efficient lamella clarifier process, it takes only 10 minutes to complete the flocculation, and it takes less than 20 minutes of precipitation to obtain good treatment water quality.
The efficient lamella clarifier process runs very flexibly. The process is relatively simple to open and close, and it can cope with large changes in processing flow. For the treatment water quality, the sudden change of raw water quality can be dealt with by adjusting the sludge return rate (such as the generation of peak turbidity), and the sludge return rate can be adjusted by adjusting the number of reflux pumps working.
