Vågen ODA is an energy-efficient solid-liquid separator with a self cleaning function and high capacity. The opening between the fixed and the rotating oval rings lets the liquid through and guides and pushes the solids further in the process. The rotation between the rings cleans the system and prevents clogging of the dried sludge. The process can be run continuously and is automated.

There is little need for operator control and the self-cleaning function provides good flow in the separation process. The oval rotating rings transport the sludge towards the outlet of the machine while simultaneously separating the water from the sludge. The structure of the system is simple and requires little maintenance. Low rotation speed results in long operating time and low maintenance costs. Compared to other dewatering systems, Vågen ODA has low energy consumption. The energy consumption varies from 0.2 kW to 1.5 kW from the smallest to the largest machine which gives from 23 to 130 m3/hour capacity. The separator is a complete sludge dewatering system that can be adapted to most processes and industries. The system can be supplied with associated systems for feeding and output, and can be operated as a continuous process.
ODA – Properties
No clogging or sludge build-up
Continuous separation of particle liquid and self-cleaning during operation.
The oscillating discs are cleaned at the same time as it dewaters and drives the sludge towards the outlet.
Stable dewatering capacity
Through self-cleaning and uninterrupted operation, the system provides high capacity and ensures smooth operation.
Long service interval
Simple structure and low rotation speed result in long maintenance and service intervals.
Wear and tear and the need to replace wearing parts are low compared to other similar equipment.
Applications
Vågen ODA can effectively dewater most types of sludge and gives good results both with and without the use of polymer. The machine is used worldwide in the food and fishing industry, but dewaters and cleans sludge from a wide variety of industries.
