Compact Units Pretreatment Plants For Wastewater Treatment Description
This Combined Pretreatment Compact Unit equipment is fed by a pump or to gravity, through a fixed pipe. The effluent passes through a screw screen that removes the most large solid particles, then goes to a sedimentation tank where the particles sedimented are then removed by a system of scews. As an option you can install the system for removal of fats and suspended oils.
Combined pretreatment system is an answer to the high civil works costs and large footprint required to execute complete pretreatment systems in concrete, screening channel, sedimentation tanks and hoppers FOG removal. The DAGYEE system is a state-of-the-art combined pretreatment system designed to optimally perform all the effluent pretreatment function, screening, grit removal, FOG removal, in a single stainless steel machine.
Combined Screening Component
Dependable, complete and compact unit
performing the following process steps:
Fine screening
Screenings dewatering
Grit separation
Grit dewatering
Grease separation and removal (optional)
Combined Screening Working Principle
Combined unit for wastewater pretreatment Introduce sewage treatment plants. they perform Fine screening, grit removal and optional grease removal.Wastewater passes through spiral screen, solids Materials larger than the mesh size,The size is captured and removed from the system. they are compaction at the end of the screen conveyor before unloading.
The wastewater flows into the sedimentation tank. finer solid matter still present in wastewater Settled in a tank and conveyed to a hopper by a horizontal screw conveyor is placed at the bottom of the tank. OneInstallation of inclined screw conveyor for sand removal conveying the sand accumulated in the hopper,Drain into a container. filtered water leaves The system passes through an outlet tube placed on the upper level.Grease removal unit can be integrated into DAGYEE combination units are available upon request.
The wastewater firstly enters the tank where a screw screen is placed.
Big size solid materials are filtrated by the screw screen and a screw conveyor moves the solid materials captured up to the discharge point. At the end of the conveyor, they are pressed by the compaction unit before discharge.
The water which has still solid materials in smaller sizes flows through the sedimentation tank. The particles are settled by time and a horizontal screwconveyor transports them to the collection hopper.
Finally, they are conveyed by the grit removal screw conveyor to the discharge point.
