Packaged Compact Units Pretreatment Plants for wastewater treatment | Pre-Assembled & Skid-Mounted for Easy Installation

Compact Units Pretreatment Plants For Wastewater Treatment 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 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

This compact pretreatment unit  provides mechanical pretreatment on municipal or industrial wastewater treatment plants. All the steps of conventional pretreatment are combined in one sole equipment without any civil works constraints: screening, degritting and degreasing.
STEP 1 : fine screening – separation liquid/solidsUnité Prétraitement Compacte
ETAPE 2 : sand settling tank
STEP 3 : collection of the sand from the settling tank bottomUnité Prétraitement Compacte
ETAPE 4 : sand evacuation

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 Screening Advantages

• Small space requirements
• Integrated emergency bypass of the screens– Design of screens for prolongs durability of brushes = cost-efficient
• Customized design to suit project requirements– High efficiency
• Patented and for years proven solution for preliminary treatment
• Washing of screenings already at the basic models
• Aeration with grease removal
• Standard AISI 304, possibility of AISI 316L and AISI 316

Combined Screening Applications

• Pre-treatment of waste water at WWTP
• Pre-treatment of waste water from fecal stations
• Pre-treatment of industrial waste water
