AFM® 13"X 54" Ultra Fine 80 Litre Filter with Auto Backwash

AFM® Graded Ultra-Fine Sediment Filter – 13"X 54" / 80L FRP Vessel with Auto Backwash

Overview

Upgrade your pre-treatment process with this high-performance sediment filtration package, engineered specifically for the removal of sub-micron particles and dissolved metals. Featuring a 13"X54" (80 Litre) corrosion-resistant FRP vessel and a fully automated Runxin control valve, this system provides a "fit and forget" solution for reducing turbidity and organic fouling in sensitive membrane systems (RO/UF) or industrial process water.

Advanced AFM® Grade 0 Media

Unlike standard silica sand or anthracite, the system is filled with 2 x 25 Kg bags of AFM® Grade 0 (0.25 - 0.50 mm), and 1 x 25Kg bag of AFM® Grade 1 (0.4 mm - 0.8 mm) an activated, graded filtration media bed that achieves what conventional media cannot:

• Superior Mechanical Filtration: Capable of filtering particles down to 1 micron (95% removal efficiency) , making it ideal for polishing fine suspended solids.
• Electro-Adsorption: Leveraging its negative surface charge, the media actively adsorbs positively charged particles, including metal hydroxides, flocs, Iron (Fe), Manganese (Mn), and Arsenic (As) .
• Organic & Emerging Contaminant Reduction: Proven to adsorb organic substances, hydrocarbons, and microplastics that typically pass through sand filters.
• Biological Stability: Resists biofouling and prevents "clumping," ensuring consistent backwash efficiency.

System Components & Specifications

• Vessel: 13" x 54" High-Grade FRP (Fiber Reinforced Plastic) – 80 Litre capacity, suitable for high-flow applications with low backwash velocity requirements (< 30 m/h or 12.3 gpm/ft²).
• Control Valve: Pre-installed Runxin Auto Backwash Filter Valve, programmed for automatic regular back-washing and rinsing to fluidize the AFM bed and purge captured contaminants.
• Complete Internal Kit: Includes custom Top & Bottom strainers and a central riser pipe, designed for even water distribution and minimal pressure loss.
• Installation Ready: All necessary seals, O-rings, and a compatible transformer for the valve's power supply are included. No hidden parts required.

Key Benefits

• Reduced OPEX: AFM's longevity outlasts sand and requires less frequent media replacement can last up to 20 years.
• RO Protection: Significantly reduces the SDI (Silt Density Index) to protect downstream membranes from particle fouling.
• Low Backwash Velocity: Specifically graded for systems where backwash flow rates are limited (below 30 m/h).
