TECHNICAL SPECIFICATIONS
ENDEMIC Rotary Disc Micro-Filter
ENRODISC® FILTER is a compact, mechanical, and self-cleaning filter unit designed
to optimize efficiency without consuming energy under normal operating conditions. It
automatically rotates when the filter surface reaches maximum clogging due to
accumulated solids, ensuring continuous filtration.
High-Efficiency Filtration
Compact and Innovative Design: The ENRODISC® FILTER boasts a high filtration area within a compact structure, making it ideal for tertiary wastewater and industrial process water applications. Its advanced design facilitates faster particle separation during the self-cleaning process, thereby increasing filtration capacity.
Versatile Filter Surfaces: The filter utilizes either polyester fabric or stainless steel surfaces, with mesh sizes ranging from 10-100 µm. Each disc comprises two micro-filter panels that can be easily assembled and removed, simplifying maintenance.
Simple Operation
Effluent Treatment: Effluent is fed by gravity into the central drum, passing through the filter panels from inside to outside. Solids are retained inside the discs, while purified water flows to an external tank or basin.
Automatic Rotation: Under normal conditions, up to 65% of the discs are submerged. They remain stationary until clogging occurs, then rotate automatically to initiate the self-cleaning process when the water level reaches a maximum threshold.
Self-Cleaning Mechanism
Backwash Process: As solids accumulate, the water level rises, triggering the backwash process. The discs rotate, and the blinded surfaces are cleaned using pressurized filtered water with counter-current and pressure nozzles. Solids are then discharged into the collector flume and removed.
Easy Maintenance: Cleaning nozzles are designed for easy maintenance and replacement. Filter panels can be swiftly replaced without draining the tank or removing the filter, thanks to the locking screws on the cover.
Turnkey System
In the compact design of ENRODISC FILTER®, filter surfaces made of polyester cloth or stainless steel are used for filtration. The contact areas of this filter with water consist of small open surfaces between 10-100 µm. The discs that make up the Enrodisc Filter® structure consist of two micro filter panels, which are very easy to assemble and disassemble. A disc structure is created by placing these two filtering panels in their places with the guide feet and closing the top cover.
The principle of discs in the filter operation is extremely simple. The water to be treated is usually gravity fed inside the central drum and flows from the inside out through the
panels. Solid particles are separated from the water by filtration panels placed on both sides of the discs. While solids are kept inside the discs; The purified water flows into
the same tank or basin containing the machine.
Discs operate underwater up to approximately 65% of their diameter. During normal operation, the discs remain constant until the water level in the supply channel reaches a predetermined value due to clogging due to the accumulation of solids.
With the increase in the amount of particles on the micro-filter, the inlet water level continues to rise. Backwash operation starts automatically when the inlet water reaches
the specified water level. The discs placed on the drum start to rotate, while rotating, the dirty filter surface is cleaned by backwashing with filtered pressurized water with the help of counter-current and nozzles. Solid particles are separated and the reject water discharged into the collecting hopper is removed from the system. Cleaning nozzles are designed for easy maintenance and replacement.
Each filter panel that makes up the disc segments can be easily replaced in seconds by simply loosening the locking screws of the cover. The panels can be easily and quickly removed without the need to empty the tank or remove the filter.
Fully Equipped Delivery:
The ENRODISC® FILTER is delivered as a turnkey system, complete with a backwash system including a pump, piping, and spray nozzles. Maintenance of the spray nozzles is automated with linear actuators for the nozzle bar and top cover.
Adjustable and Automated: The distribution drum is driven by a gear motor with adjustable rotation speed via frequency control. An electrical panel oversees all operational processes automatically.
Quality Assurance
Endemic is certified with ISO 9001:2015, ISO 14001:2015, ISO 45001:2018, ISO 10002:2018, and CE marking, ensuring high-quality products and excellent customer support. The ENRODISC® FILTER complies with the EC Machinery Directive and is welded to European standards.
Experience the efficiency and reliability of ENRODISC® FILTER for your filtration needs with the assurance of top-tier quality and performance.
"HEAVY DUTY" DESIGN
ENRODISC® FILTER utilizes surface filtration with an inside-out flow path for optimal efficiency. Influent enters the central drum and flows into the filter segments by gravity. The disks, partially submerged, allow solid materials to be directed to the waste flume. Solids accumulate on the inside filter surface and are backwashed using counter-current spray nozzles. The disc rotation is limited to the backwash process, optimizing energy usage.
HIGH EFFICIENCY BACKWASHING SYSTEM
Captured solids are effectively removed using a positive pressure spray cleaning system. This backwash cycle is automatically triggered by a level sensor in the inlet channel, ensuring efficient operation during filtration. The spray mechanism thoroughly cleans the filter surface, and the Enrodisc's design minimizes lifecycle costs with fewer moving parts and reduced energy demands for backwashing.
MODIFICATION OR UPGRADING OF EXISTING PLANTS
The discfilter is also used to ensure that existing filtration systems can be upgraded using the same concrete structures and existing tanks or simply by replacing the panels and the washing system.

HOW IT WORKS
Water to be filtered is guided into the rotor drum and flows by gravity into the discfilter, through openings in the drum, and passes through the filter cloth.
-
Suspended solids are separated and accumulate on the inside of the filter cloth.
-
When the water level inside the filter increases to a preset point, the discfilter starts rotating and switches to the backwash period.
-
The high pressure backwash spray nozzles remove the
-
accumulated suspended solids into the reject flume located inside the central drum.
-
The suspended solids are then discharged via the reject pipe. 65% of the disc area is submerged in operation to provide a high area through which the flow can pass.
