High Efficiency Sedimentation Tank

Overview:

High efficiency sedimentation tank is a compact,efficient and flexible new sewage treatment process,which can be widely used in various fields,and can be used to treat industrial and domestic sewage,drinking water,rainwater and tertiary wastewater.High density sedimentation tank is an advanced patent clarification technology developed by the French Deliman company.The main technology is carrier flocculation technology,which is a rapid precipitation technology characterized by adding high-density dissolved medium particles (such as micro sand)in the coagulation stage,using the gravity setlement of the medium and the adsorption of the carrier to accelerate the "growth"and precipitation of the flocs.

Main classification
RL type high-density sedimentation tank
It is the most widely used high-density clarifying tank(adopted by 95%of projects).In this type of high-density clarification tank,cement mixture flows into the lower part of the inclined pipe of the sedimentation tank,and the sludge is separated from the water in the sedimentation zone under the inclined pipe.The sedimentation at this time is an obstruction sedimentation,and the remaining flocs are trapped by the inclined pipe.The separation is carried out according to the mechanism of the inclined pipe sedimentation tank.Therefore,the whole precipitation process in the same structure is carried out in two stages:deep obstruction precipitation and shallow inclined tube precipitation.Hindering the separation process of setling area is the basis of calculating the geometric dimensions of settling tank.
RPtype high scale inlet cleaning tank
When the effluent and sewage discharge standardsare not very strict,using such high-density clarifying tank is better,and it can be installed without inclined pipes.The clarifier is rarely used (only for the concentration of supernatant discharged from filter flushing wastewater,specia concentration requirements).

RPL type high-density clarifier
This type of high density clarifier is used only when it is necessary to store mud centrally and there is no reaction to the treatment.Therefore,its application is limited to carbon remova processes(non-drinking water)and special precipitation processes in industrial wastewater treatment.
