HAUS – DDI decanters for industrial processes

The HAUS DDI industrial decanter is a decanter centrifuge in two- or three-phase design for heavy-duty industrial processes. The decanter separates liquids from solids, discharges one or two clarified liquid phases and dewaters the sludge. Steiner Ukraine supplies HAUS decanters, selects the model for the process, and carries out installation, commissioning and service.

Where is the HAUS industrial decanter used?

• chemical and pharmaceutical industry;
• extraction of fats, oils and proteins;
• mining, oil and gas industries;
• produced water treatment in oil and gas, mining and chemical industries;
• by-product treatment, recycling and material recovery.

How does a decanter work?

The product enters the conveyor feed chamber through the feed pipe and, under centrifugal force, passes into the bowl, where it stratifies by density. Solids settle on the bowl wall, and the scroll conveyor transports them to the discharge in the conical section. Clarified liquid leaves over height-adjustable plates at the end of the cylindrical section. The solids conveying rate is determined by the speed difference between bowl and scroll.

In the three-phase version, the decanter separates the solid phase and two immiscible liquids.

How is the HAUS industrial decanter built?

• reinforced design and wear-resistant materials;
• wear protection options for abrasive processes;
• material of construction, wear protection, motor power and gearbox torque are selected for the process.

The main motor drives the bowl, the secondary motor drives the scroll. Both motors are controlled by frequency converters and connected by a high-torque gearbox without a friction clutch. The differential speed is adjusted automatically to the amount of solids. On the touch panel with PLC, automatic modes are selected, sludge dryness is set and alarms are monitored.

Which models are in the DDI series?

The series includes the sizes DDI 2342/2343, 3042, 3532/3533, 3542/3543, 4042/4043, 4742/4743, 5342/5343, 6542/6543, 8242/8243. Weight is from 900 to 15500 kg, installed drive power from 9.7 to 197 kW depending on the model.

FAQ

What capacity does the DDI series have?

According to the manufacturer, from 10 to 100 t/h depending on the model and process.

How much does a HAUS industrial decanter cost?

The price is calculated on request. It depends on the size, materials, wear protection and configuration.

For wastewater sludge dewatering, use HAUS DDE decanters. For oil polishing after the decanter, use HAUS I series separators.
