High-Capacity Combined Wastewater Pre-Treatment Unit for Municipal Use

Combined wastewater pretreatment unit description

The Combined Pre-Treatment Plant is a complete, above-ground headworks requiring minimal space and civil works. Debris, grit/sand and grease can all be removed in this one compact system. For small plants, this system can function as an entire pre-treatment headworks or it can be a simple, economical way to increase pre-treatment capacity.

With the addition of aeration and DAGYEE’s proprietary grease removal system, this unit can become a Septage, Sludge and FOG processing station. Depending on preference or application, a variety of screen types can be incorporated into the compact plant. With over 10 years of experience and 500 installations worldwide, DAGYEE’s application and technical knowledge insures proper sizing and component selection for each specific application.

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.
