Screw squeezing grid

Scope of application of screw squeezing grid:

• Domestic wastewater treatment;
• Pulp and paper industry;
• Meat processing industry;
• Fruit and vegetable processing enterprises;
• Food industry.

Characteristic features of the Ekoton screw squeezing grid

• The peculiarity of the auger grid is its functionality. It extracts medium and fine waste from industrial and domestic wastewater, washes, squeezes out and transports it to a waste container. The RVO EKOTON screen is most convenient for fine mechanical wastewater treatment.
• A slotted or perforated sieve is installed at the bottom of the grate. As wastewater passes through the sieve, waste is retained on the surface of the filter cloth. To clean the web in the filtration zone, the auger is equipped with a brush. In the upper part of the grate there are zones for washing and squeezing waste.
• Thanks to the built-in waste washing function, organic compounds remain in the wastewater, which contributes to the biological treatment process.
• The axleless auger prevents the screen from blocking, clogging or seizing, even when working with fibrous materials.
• The use of perforated fabric with small holes solves the problem of retaining even hard-to-catch contaminants in the form of hair.
• The grate can be equipped with a device for unloading washed and dehydrated waste into plastic bags, which is not only extremely convenient for further transportation of waste, but also prevents the spread of odors.
• The design solves the problems associated with the operation of a significant part of the additional sewerage equipment - it does not contain complex mechanisms and components that require constant and labor-intensive maintenance.
• The RVO auger screen is easily integrated into an existing complex of treatment facilities and synchronized with other types of equipment.
• The screens are designed for use in wastewater with pH = 6.5÷8.5.

Ease of operation and maintenance of Ekoton screw squeezing grid:

• the gratings are easy to maintain due to the availability of the main components in working order.
• the technical ability to compact the volume of incoming waste up to 40% already in the grid eliminates the problem of installing additional equipment for squeezing waste.
• the simplicity of the design makes it easier to assemble and install the RVO EKOTON.
• retention of incoming waste, its transportation and extraction is carried out in one device, using only one electric drive.
• RVO does not require constant or complex technical maintenance.
• Due to the use of high-precision production technologies, trouble-free mating of housing parts and grille mechanisms is achieved.
• equipment can be placed in screen buildings at the wastewater treatment plant site.
• Outdoor installation is possible if a grille heating device is used.

Reliability and durability of Ekoton screw squeezing grid:

• All work is carried out by a screw, so the design does not have a significant number of rotating parts. This increases the reliability and durability of the grille.
• The auger is made of wear-resistant carbon steel, and a self-cleaning, durable brush is installed in the filter cloth area.
• The use of stainless steel (AISI 304, AISI 316) in the structure ensures its durability, which is very important for working in an aggressive wastewater environment.
