1. Introduction: Replacing Traditional Sand Filters

In the competitive landscape of industrial water treatment, traditional sand filters often struggle with excessive backwash water waste and bulky footprints. The AGF All-Plastic Shallow Media Filter, a patented technology by ARKAL, redefines efficiency. Featuring a unique 48" spherical design and advanced ASM special media, the AGF system is the next-generation newcomer set to dominate the media filtration industry.

2. Core Advantages of the AGF All-Plastic Shallow Media Filter

The AGF system provides significant ROI through its specialized engineering:

70% Backwash Water Savings: Optimized hydraulics mean shorter backwash cycles. The system consumes only 30% of the water required by traditional sand filters.

Corrosion-Resistant All-Plastic Construction: Built with polyester composite materials, the system offers extreme chemical stability and is suitable for harsh environments with pH levels from 0 to 14.

Modular & Scalable Design: The modular configuration allows for flexible arrangements based on flow requirements. Its compact footprint enables installation on standard cement floors without expensive reinforced foundations.

Zero-Downtime Operation: Units within the AGF system are backwashed sequentially. This ensures an uninterrupted water supply even during the cleaning cycle.

3. Working Principle: Laminar Filtration & Internal Turbulence Backwashing

The efficiency of the AGF filter is driven by two distinct phases:

Filtration Phase

Sewage enters through a three-stage water distributor, ensuring a stable laminar flow (advection) through the media layer. Impurities are trapped with high precision. At the bottom, 55 mushroom-shaped collectors ensure uniform discharge, allowing for high-flow rate filtration without compromising water quality.

Backwash Phase

When the pressure differential (ΔP) reaches the setpoint, the three-way valve automatically switches. Filtered water is redirected into the backwash tank to create internal turbulence. The filter media particles rub against each other, effectively stripping away trapped sludge with zero material leakage.

4. ASM Special Media: The Secret to Superior Filtration

While traditional systems use quartz sand, the AGF system utilizes ASM (ARKAL Special Media) for enhanced performance:

Electrostatic Adsorption: The media surface carries a negative charge, significantly improving the capture of microorganisms and large organic molecules.

Self-Purifying Properties: Infused with rare metal catalysts, ASM media inhibits bacterial growth, preventing "mud ball" formation and media fouling.

10+ Year Service Life: With a wear rate of less than 0.1%, ASM media is incredibly durable, reducing long-term maintenance costs.

Ultra-Smooth Surface: Microbial sludge is easily flushed away during backwash, maintaining the media's integrity.

6. Industrial Applications & Use Cases

The versatility of the AGF system makes it ideal for various sectors:

Industrial Cooling Systems: Side-stream filtration for cooling towers in steel plants, power plants, and chemical manufacturing to prevent scaling and bio-fouling.

Wastewater Reuse: Tertiary treatment for sewage plants to enable reclaimed water for industrial use.

Seawater Pretreatment: Protecting downstream membranes in desalination plants and ensuring water quality for aquaculture.

Environmental Protection: Effective control of blue-green algae in large-scale aquatic systems and landscape water.
