Amiad Spin Klin Disc Filters: Precision Depth Filtration for Industry

For industrial applications requiring robust, corrosion-resistant, and micron-precise water filtration, the Amiad Spin Klin™ series stands out as a top-tier solution. As a distributor for high-performance water treatment technologies, Purecowater provides these advanced disc filtration systems to tackle difficult solid and liquid filtration problems.

This article explores the capabilities of the Amiad Spin Klin™ disc filters, detailing their unique technology, technical specifications, and why they are the preferred choice for protecting downstream equipment like Reverse Osmosis (RO) units and membrane elements.

What is Spin Klin™ Disc Technology?

Unlike traditional screen filters that filter primarily on the surface, Spin Klin™ relies on depth filtration. The core of this technology is a stack of thin, color-coded polymeric discs. Each disc is continuously grouped with diagonal grooves on both sides. When these discs are stacked and compressed on a specialized spine, the grooves form a matrix of consecutive crossing points.

This creates a significant series of channels that effectively trap solids not just on the outer surface, but throughout the entire depth of the disc element. This design offers a distinct advantage when dealing with soft, organic contaminants that can easily squeeze through standard screens [us.amiad.com].

Key Advantages of Disc Filtration

• High Dirt Holding Capacity: The depth of the disc stack allows for capturing a larger volume of suspended solids before cleaning is required.
• Micron-Precise Filtration: Discs are color-coded by micron size, ranging from 10 to 400 microns, ensuring consistent filtrate quality.
• Corrosion Resistance: Constructed from all-polymeric materials, these filters are chemically resistant and ideal for harsh environments, including seawater applications.

How the Automatic Backwash Works

One of the defining features of the Spin Klin™ system is its efficient, automatic self-cleaning capability. The backwash cycle is initiated by a pressure differential or a timer, ensuring the system runs continuously with minimal downtime.

1. Release: The compression spring on the spine is released, allowing the discs to separate slightly.
2. Jet Spray: Tangential jets of filtered water are sprayed at high pressure against the spinning discs.
3. Spin and Flush: The discs spin freely, dislodging trapped solids which are then flushed out the drain port.
4. Resumption: The spine re-compresses the stack, and the filter returns to filtration mode.

This process is extremely short (often seconds) and consumes a minimal amount of water, making it an eco-friendly and cost-effective choice for industrial plants [amiad.com].

Technical Specifications and Models

Amiad offers the Spin Klin™ in various sizes to accommodate different flow rates and installation footprints. Below is a comparison of the popular industrial models available.

Model	Connection Size	Flow Rate Range	Filtration Degree
2″ Spin Klin™ Compact	2″ (50 mm)	44 – 88 gpm (10 – 20 m³/h)	10 – 400 micron
2″ Spin Klin™ Standard	2″ (50 mm)	44 – 396 gpm (10 – 90 m³/h)	10 – 400 micron
3″ Spin Klin™	3″ (80 mm)	88 – 792 gpm (20 – 180 m³/h)	10 – 400 micron

Note: Maximium flow rates depend on the water quality and filtration degree required.

Modular Design

The beauty of the Spin Klin™ system is its modularity. Units can be installed in batteries (multiple filters manifolded together) to handle significantly higher flow rates. This allows for easy system expansion as your facility’s water demands grow.

Common Applications

Due to their versatility and chemical resistance, Spin Klin™ filters are used across a wide range of industries:

• Pre-Filtration for Membranes: Protecting Reverse Osmosis (RO) and Ultrafiltration (UF) modules from fouling.
• Process Water: Filtration of cooling tower side-streams and process water loops.
• Water Reclamation: Treating tertiary wastewater for reuse.
• Seawater: Pre-filtration for desalination plants where corrosion is a major concern.
• Drinking Water: Removal of arsenic and other particulates in municipal treatment plants.

Why Choose Amiad Spin Klin™?

For facilities dealing with organic load or fine particulates, standard screen filters often struggle with rapid clogging (“cake” formation). The Spin Klin™ depth filtration technology excels in these scenarios by trapping particles throughout the disc structure, ensuring longer operational cycles and more reliable protection for downstream equipment.
