Disc Filter for Pure Water Treatment

A Disc Filter, also known as a stacked media filter or automatic self-cleaning filter, is a highly efficient and compact filtration system designed for the pre-treatment stage of pure water systems. Its primary purpose is to remove suspended solids, particulate matter, silt, and other microscopic contaminants from feed water.

By providing reliable protection for downstream equipment such as Reverse Osmosis (RO) membranes and ion exchange resins, disc filters are critical components in ensuring the efficiency and longevity of complete pure water treatment systems.

Working Principle

The core of the disc filter is a stack of precision-engineered polypropylene discs. Each disc features a specific pattern of grooves and traps on both sides.

Filtration Cycle: During filtration mode, water flows from the outside of the disc stack towards the inner core. Suspended particles are trapped on the disc surfaces or within the intricate groove networks. Clarified water passes through and collects in the central manifold, exiting as clean effluent.

Backwash Cycle: When differential pressure across the disc stack 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 slightly expands the disc pack, creating a powerful reverse flow that scours the discs and flushes trapped solids to drain.

Main Components

Filter Vessel (Body): Constructed from reinforced polypropylene (FRPP), stainless steel (SS304/SS316L), or other corrosion-resistant materials
Disc Stacks (Filter Elements): High-quality, durable polypropylene (PP) elements in various filtration ratings (5μm to 200μm)
Central Manifold / Collecting Pipe: Gathers filtered water from each disc stack and directs it to the outlet
Backwash Mechanism: Piston or spring assembly controlling disc stack compression and expansion during filtration and backwash cycles
Control System: Mechanical timer/pressure differential controller or sophisticated PLC-based unit automating backwash sequences
Inlet/Outlet & Drain Valves: Multi-port valves or individual solenoid valves directing flow paths for filtration and backwashing

Key Features

High filtration efficiency with consistent particle removal down to micron level

Fully automatic self-cleaning operation with minimal operator intervention

Low operating cost with reusable disc media lasting for years

Compact footprint with high filtration area in minimal space

Minimal water loss (typically 20-60 liters per cycle) with over 99% recovery

Robust design with simple mechanics ensuring high reliability

Applications

Disc filters are ideally suited for pre-treatment stages in various pure water and industrial applications:

RO System Protection as final pre-filter
Pre-filtration for UF/NF systems
Cooling water filtration for heat exchangers
Process water treatment for manufacturing
Plating and chemical processes
Reclaimed water reuse polishing
