Spin Klin^TM disc technology uses thin, color-coded polymeric discs that are diagonally grooved on both sides to a specific micron size. A series of these discs are stacked and compressed on a specially designed spine, with the top groove in the opposite to the groove below. This creates a filtration element with a significant series of channels, effectively trapping the solids. The disc stack is enclosed in corrosion and pressure resistant housing.

 

Arkal Disc Filters | Self Cleaning Water Filter

• Real-time self-cleaning filters: clean themselves automatically when head-loss across the screen reaches a preset value
  
• Uninterrupted water supply: the filter cleans itself in just seconds without interrupting downstream flow
  
• Modular structure: different diameters, suitable For use singly or in manifold configuration providing optimal solutions to meet specific customer requirements
  
• Flexibility of control options: Hydraulically or electronically controlled units. Electric control boards to suit specific needs. Flushing according to pressure differential and/or according to time. Continuous flushing, alarm signals, flushing counter and more
  
• Wide range of filtration degrees: from 3500 To 3 micron

General

The Arkal 2”- 3” SpinKlin^TM series are modular, all polymeric, automatic disc filters with a patented self-cleaning backwash mechanism.
The 2”- 3” SpinKlin^TM systems range in flow rates from 10 m3/h (44 gpm) to 200 m3/h (880 gpm) with filtration degrees ranging from 20 - 400 micron.
Inlet/Outlet from 80 - 200 mm (3”- 8”) diameter.

The Filtration Process

The discs are stacked on the SpinKlin^TM spine and assembled according to pre-determined water filtration requirements.
During filtration, the discs are compressed by means of a pre-loaded spring and differential pressure, forcing the water to pass through the grooved disc surface, thus trapping the solids.

The Backwash Process
Activated by a pre-determined time trigger or differential pressure, the system enters backwash mode. The inlet valve port shuts while the drain valve port opens. During the backwash process, pressure is released and the spine’s piston elevates, releasing the compression on the discs. Tangential jets of filtered water are then forced through the nozzles positioned along the spine. At this stage the discs spin freely, loosening the trapped solids which are then flushed out.
During the flushing cycle each filter pod is backwashed sequentially, while the other pods continue to supply filtered water downstream. When a pod begins the backwash  cycle, the system valves automatically reverse the flow in the pod, allowing filtered downstream pressurized water to backwash the filter.

External Source Backwash

Each filter is backwashed sequentially, while the other filters continue to supply filtered water downstream. In each backwashed filter the inlet & outlet valves automatically close and the drain & external source valves automatically open.
Pressurized filtered water from the external source header enters the backwashed filter through its outlet port and backwashes it.

• Higher energy for low operating pressure applications and fine filtration degrees

Air Aided Backwash (for 2” SpinKlin^TM systems only)

Main benefits:

• Enhanced cleaning power, especially on fine filtration degrees
• Less backwash water volume
• Low pressure operation
• Reduced backwash time per filter pod (<10 sec)
• The air and water mix at a minimum pressure of 2.5 bar generates
  the optimal cleaning performance in SpinKlin^TM technology

During the flushing cycle, each filter pod is backwashed sequentially while the other pod continues to supply filtered water downstream. When a pod begins the backwash cycle, the valves automatically reverse the flow in the pod, and open the air valve, allowing compressed air to push the filtered water stored in the accumulator through the backwash manifold and into the SpinKlinTM filter being backwashed.
Each backwash cycle requires a time delay to allow the water tank to be filled with clean water and air, making the total backwash duration longer than in regular systems.
A clean & dry air pressure source is necessary to operate the filtration system (supplied by the customer).
