SOBYE Pretreatment

Sobye Belt Filter TD

With our Sobye filter you get an automatic, self-cleaning belt filter that removes particles from water in a cost-effective and space-efficient way. The Sobye filter replaces the standard primary filtration of municipal waste water and sedimentation processes, but on a much smaller area. Due to its effectiveness, it offers an investment saving of up to 50%. The Sobye filter is also used successfully in fish farming and fish processing. Further advantages are that the system delivers an extremely dry sludge and chemicals are normally not required, which facilitates the further treatment or processing of recoverable material.

This is how the Sobye belt filter works
The untreated water is led into the filter and the particles are separated when the water passes through the filter fabric. The screen fabric rotates when it needs cleaning. The fabric is cleaned principally by brush and then flushed at a high pressure, which is both cheaper and in many respects better than air cleaning.

The particles separated by the brush are transported internally in the filter to a press that de-waters the sludge to a very high dry content. The waste water is drained out of the filter separately and can normally be led back to the incoming water.

Application areas

Fish farming
In fish farming there is a natural water contamination from fish faeces and leftover food residue. High levels of this contamination can damage the growth and survival of fish stocks. The Sobye filter removes particles and allows you to maintain a good water quality.

Fish processing industry
The Sobye filter has been used successfully for many years in the treatment of waste water from the fish processing industry. The waste water may contain high levels of particulate matter and oxygen-consuming substances, often in combination with grease and oil, for example. By using a Sobye belt filter these levels can be effectively lowered while maintaining performance and low or no chemical consumption.

Primary filtration of municipal waste water
The Sobye filter replaces the standard primary filtration of municipal waste water and completely replaces the sedimentation processes, but on a much smaller area.
