Combined Wastewater Pre-Treatment Unit with Advanced Coagulation-Flocculation

Combined wastewater pretreatment unit description

Mechanical pre-treatment is very important for protection of subsequent processes in a
wastewater treatment plant in order to operate the entire plant reliably. Wastewater has to be
pre-treated before being transferred to the subsequent stages of the wastewater treatment plant so that the overloading of the downstream treatment system is avoided.

Wastes, passing through the screw screen, are screened and the bigger solid particles are
removed. Then, effluents pass in the tank (hopper) section, where finer solids particles are
allowed to settle down and are removed by a low rotating shaftless screw system. As an option, the unit can be designed with an oil/grease removing system.

Options of alternative voltage and frequency, degree of motor protection, control panel, drive
guard, screen type, overflow chutes, fixed internal pipe are available upon request.

DAGYEE Uluslararası Combined Wastewater Pre-treatment Units have screw screen, screenings treatment, grit traps (for solids- stones, grit, sand, etc. removal) and as optional grease traps (for fat, oil and grease removal).

Combined wastewater pretreatment unit 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 wastewater pretreatment unit 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.

Combined wastewater pretreatment unit Parameter

Combined wastewater pretreatment unit advantage
