FILTERING MICROSCREEN ROTADISC

ESTRUAGUA

The Filtering microscreen ROTADISC sieve is a very robust, mono block piece of equipment designed for micro solids filtration, with a minimum mesh of 10 microns and maximum 1000 microns.

Due to its compact and resistant design, this equipment can work without any problems during 24 hours for a long period of time and without requiring any type of maintenance.

The ROTADISC Micro sieve can be provided in a compact version or ready for civil work installation.

The Filtering microscreen ROTADISC disc filter has a filtering mesh with a self-cleaning system with pressurised water.

The equipment has revolving discs lined in parallel along a horizontal axis. The discs are submerged up to 65% in the filtered water. Each disc is made up from several meshed stainless steel segments through which the water flows from inside out. The obtained filtering exits the front side of the equipment.

The particles remain retained in the mesh and descend by the effect of the gravity. With time the mesh starts to fill up and this causes an increase in the loss of the load.

When the established maximum pressure differential is reached, the washing cycle begins. While the discs slowly turn, water jets send water towards the mesh, dragging the solids to a hopper situated in the centre part of the equipment.

The same filtered water pumped by means of a pump installed in the exit of the filter can be used as washing water. The filtering continues during the washing cycle.

• Free plate sieve with a large filter surface

Filtering discs: made completely out of stainless steel quality Aisi-304 or 316, this cylinder is constructed in a specially designed machine for this purpose. This element is composed of various sections which are detachable for maintenance, and which can be easily dismounted or adjusted.

• Filter mesh of 10 to 1,000 microns made in polyester.
• Modular design.
• Fast and easy access to the filtering cylinder from the outside of the filter

Frame: In strong meccano type construction, welded in Stainless Steel quality Aisi-304 or 316, it is provided with entrance and exit connections, anchoring legs, watertight elements, etc…

System of waste elimination: This takes place by means of a combination of water sprinklers, the rotating manner of the filtering discs and the waste transporting hopper found inside the filtering cylinder.

Drive: By means of a worm gear box, of widely determined proportions which is fixed by means of a reaction arm.Minimum protection considered in motor IP-55 and isolation class F
