Country Of Origin : India

Cynergy Enterprises Radial Edge Disc Filter (REDF) is an advanced fully automatic backwash filtration system designed for both cooling water treatment and process liquid filtration. It efficiently removes suspended solids, silt, rust, and impurities while operating continuously with minimal maintenance. The REDF is also an ideal modern replacement for traditional Sparkler Filters, offering cleaner filtration, automatic operation, reduced labor, faster cycles, and lower downtime. Built in high-grade stainless steel, it is suitable for cooling towers, chillers, HVAC systems, edible oil, chemicals, pharma, beverages, and industrial plants where reliable high-performance filtration is required.


Purpose & Application

The Auto Back Washable Filter (REDF) is designed for chemical reactions where salt precipitates, activated carbon powder, or catalyst is present in the process stream.

This system helps achieve efficient solid–liquid separation without frequent manual intervention.

System Components

The REDF system consists of:

  • Filter housing

  • Filter candles

  • Radial edge disc filtration elements

  • Instrumentation for operation and monitoring

These components work together to ensure continuous filtration with automatic cleaning.

Material Options

Filter housings are available in the following materials to suit different chemical environments:

  • SS 304

  • SS 316

  • SS 316L

  • Duplex Stainless Steel

  • Hastelloy

  • PTFE Coating / Lining

These materials ensure resistance against corrosive chemicals and longer equipment life.

Unique Filtration Technology

Unlike conventional filtration systems, REDF uses radial flow filter candles.

In this design:

  • Feed flows radially across the membrane surface

  • Solid particles are trapped on the filtration surface

  • Clean filtrate passes through the filter element

This radial flow design improves filtration efficiency and reduces clogging.

Features & Benefits

  • Zero manual labor – no need to open the filter housing

  • Hi-flow powder not required for filtration

  • Operational cost almost zero

  • Dry cake discharge possible

  • Long service life of filter candles

  • Fully automatic backwash cleaning

  • Customized designs available as per process requirement

Applications

The REDF system is suitable for:

  • API (Active Pharmaceutical Ingredients)

  • Activated Carbon Filtration

  • Catalyst Regeneration Processing

  • Chemical & Petrochemical Industries

  • Solvent Recovery

  • Beverage Purification

Filter Assembly Components

  • Filter Candle

  • Perforated Core

  • Radial Edge Disc (E.D)

  • Bottom Cap (Closed)

  • Brush for Scraping

  • Brush Mounting Plate

Nozzle Connections

  • Inlet Nozzle – Raw feed entry

  • Outlet Nozzle – Filtrate discharge

  • Backwash Nozzle – Automatic cleaning

  • Drain Nozzle – Sludge / cake removal

Usage of Radial Edge Disc Filter (REDF)

1. API & Pharmaceutical Manufacturing

Used for solid–liquid separation during chemical reactions where solids form during processing.

Typical cases:

  • Removal of salt precipitates

  • Filtration of reaction slurry

  • Catalyst removal

  • Activated carbon polishing

Benefits:

  • Closed filtration system (important for pharma)

  • No manual filter opening

  • Cleaner product recovery

2. Activated Carbon Filtration

Common in pharma, chemicals, food, and solvent purification.

Process:

  1. Activated carbon powder is added for color removal or impurity adsorption.

  2. REDF filters the carbon powder from the liquid.

Advantages:

  • No need for filter aid powder

  • Continuous operation

  • Dry carbon cake discharge possible

3. Catalyst Recovery & Regeneration

In many chemical reactions powder catalysts are used.

REDF helps:

  • Separate catalyst particles from liquid

  • Allow catalyst recovery and reuse

  • Reduce catalyst loss

Industries:

  • Fine chemicals

  • Petrochemicals

  • Specialty chemicals

4. Chemical & Petrochemical Processing

Used for removing suspended solids from process streams.

Applications include:

  • Reaction mass filtration

  • Salt crystal removal

  • Polymer processing filtration

  • Slurry filtration

Advantages:

  • High pressure handling

  • Corrosion-resistant materials available

5. Solvent Recovery Systems

During solvent purification, solids such as:

  • Carbon powder

  • Reaction residues

  • Catalyst particles

need to be removed.

REDF provides:

  • Continuous filtration

  • Minimal solvent loss

  • Cleaner recovered solvent

6. Beverage & Liquid Purification

Used in filtration of:

  • Sugar syrup

  • Alcohol processing

  • Fermentation liquids

  • Beverage clarification

Benefits:

  • Fine filtration

  • No contamination risk

  • Automatic cleaning

Where REDF is Most Useful

This filter is especially useful where:

✔ Powder filtration is required
✔ Activated carbon is used
✔ Catalyst recovery is needed
✔ Salt precipitates during reaction
✔ Continuous filtration is required
✔ Manual filter cleaning must be avoided
