- Filtration Cycle: During the filtration mode, water flows from the outside of the disc stack towards the inner core. The suspended particles are trapped on the surface of the discs or within the intricate network of grooves. The clarified water passes through and collects in the central manifold, exiting the filter as clean effluent.
- Backwash Cycle: When the differential pressure across the disc stack (due to accumulated solids) reaches a pre-set value (typically 0.5 - 1.0 bar), the system automatically initiates a backwash cycle. No external water source is required. The controller opens a drain valve, and a hydraulic mechanism within the filter slightly expands the disc pack. A powerful reverse flow of the filtered water is released from the central core outwards, scouring the discs, rotating them, and flushing the trapped solids to the drain. This process is rapid, lasting only 10-30 seconds, and does not interrupt the main flow in multi-unit systems.
- Filter Vessel (Body): Typically constructed from reinforced polypropylene (FRPP), stainless steel (SS304/SS316L), or other corrosion-resistant materials.
- Disc Stacks (Filter Elements): The heart of the system. Made from high-quality, durable polypropylene (PP) in various filtration ratings (e.g., 5μm to 200μm). Multiple stacks are housed within a single vessel.
- Central Manifold / Collecting Pipe: Gathers the filtered water from each disc stack and directs it to the outlet.
- Backwash Mechanism: A piston or spring assembly that controls the compression and expansion of the disc stacks during filtration and backwash cycles.
- Control System: Can be a simple mechanical timer/pressure differential controller or a sophisticated PLC-based unit. It automates the backwash sequence based on time or pressure drop.
- Inlet/Outlet & Drain Valves: Multi-port valves or individual solenoid valves that direct the flow paths for filtration and backwashing.
- High Filtration Efficiency: Provides consistent and reliable removal of particles down to the micron level.
- Fully Automatic & Self-Cleaning: Ensures uninterrupted operation with minimal operator intervention. Backwash is triggered by actual dirt load.
- Low Operating Cost: The primary filtering media (the discs) are reusable for years, eliminating the recurring expense of disposable filter cartridges.
- Compact Footprint: Its modular and stacked design offers a high filtration area in a very small space compared to traditional sand or multi-media filters.
- Minimal Water Loss: The backwash cycle is extremely fast and uses a small volume of the filtered water (typically 20-60 liters per cycle), resulting in over 99% water recovery.
- Robust and Low Maintenance: Simple mechanical design with few moving parts ensures high reliability and easy maintenance.
- RO System Protection: As a final pre-filter before the cartridge filter and RO unit to remove fine particles that could foul or scratch membranes.
- Pre-Filtration for UF/NF: Protecting Ultrafiltration (UF) and Nanofiltration (NF) systems.
- Cooling Water Filtration: Protecting heat exchangers and cooling tower systems.
- Process Water Treatment: Providing filtered water for manufacturing, plating, and chemical processes.
- Reclaimed Water Reuse: Polishing tertiary treated effluent for non-potable reuse.
