The self-cleaning filterrakes made by VDZ Aqua are designed to be used in industrial as well as domestic wastewater. The filter systems are placed in a wastewater channel where very small particles even smaller than 1mm are filtered out of the wastewater. The filterrake is used in the meat industry, chemical industry, tanneries, breweries, potato processing, and wastewater of gas stations.
The filterrake has a moveable filter belt that is placed in an open channel which filters big particles out of the wastewater.
When placing the Filterrake in the channel, the system is fastened to the walls and made waterproof by means of waterproof flaps to make sure all the wastewater is forced through the filter surface.
The purpose of the filterrake is to remove the solid parts and particles from the wastewater with help of continuous moving screens. At the same time, these particles are transported to a container and it is kept there for disposal or further processing.
The separation of solid particles from the filterrake is thanks to the special shape of the filter and because of the self-cleaning movement of the filter screens in the upper part of the installation.
The standard filterrakes have a filter surface with openings of 1mm, 3mm, 6mm, 10mm, or 15mm.
The filterrake comes in stainless steel as a standard system but can also be supplied in galvanized steel.
The shaft is made of stainless steel and the filter screens are made of a combination between stainless steel and a type of plastic.

Based on our experience and know-how we created an aeration system that is more reliable, uses fewer parts but also makes more white water than traditional systems.
Our innovations have led to more flexible designs which can be built to a smaller footprint compared to traditional systems.
Through optimization of all aspects of the system, our treatments use less power, chemicals, and maintenance compared to the traditional systems.
