Microklin Self-cleaning Screen Filters

Self-cleaning screen filters revolutionize fluid filtration by seamlessly addressing clogging issues in water treatment, irrigation, and industrial processes. These filters utilize a mesh or screen to capture particles during fluid passage, and what sets them apart is their autonomous maintenance feature. Employing automatic cleaning or backwashing processes, these filters periodically reverse fluid flow or deploy cleaning elements like brushes to dislodge and flush out accumulated debris. This innovative design eliminates the need for frequent manual interventions, enhancing system reliability and performance.

Features
  • Large filtration area, reliable operating mechanism and simple construction make the SCSF filter the ideal solution for filtration of high-flow and poor quality water to very fine filtration degrees
  • Robust and reliable self-cleaning mechanism to give best results in marginal operating conditions and poor water quality
  • Automatic flushing according to pressure differential and/or time
  • Option for continuous flushing
  • Low pressure operation, suitable for 2 bar (30 psi) and lower
  • No interruption of downstream flow during flushing
  • Applications: Water supply systems, cooling water, wastewater treatment.
  • Industrial pre-filtration treatment, irrigation system.
  • Industries: manufacturing, mining, water and wastewater treatment plants, turf, agriculture, etc.

How the SCSF Filter Works

General
Technomax SCSF Series are automatic filters, with an electric self-cleaning mechanism. The “SCSF” filters range in flow-rates of up to 1800 m³/h (8000 US gpm), with screens designed ranging from 800-10 micron filtration degree. Inlet/Outlet ranges are available from 8”- 20” diameter.
The Filtering Process
Raw water enters from the filter inlet
  • and passes through the screen
  • Clean water flows through the filter outlet
  • The gradual dirt buildup on the inner screen surface causes a filter cake to develop, with a corresponding increase in the pressure differential across the screen. A pressure differential switch
  • senses the pressure differential and when it reaches a pre-set value, the cleaning process begins.
Self-Cleaning Process
The Cleaning of the filter is carried out by the suction scanner (5) which spirals across the screen, the open exhaust valves creates a high velocity suction stream at the nozzle tip which “vacuums” the filter cake from the screen. During the self-cleaning process, which takes approximately 30 seconds, filtered water continues to flow downstream.

Self-Cleaning Process

The PLC allows maximum flexibility in control options and has many features that can be incorporated per customer’s needs. During the self-cleaning cycle the PLC controls a solenoid that operates the exhaust valve by means of a hydraulic command or compressed air. The self-cleaning cycle begins under any one of the following conditions: 1. Receiving a signal from the Pressure Differential Switch 2. Time interval parameter set at the control board 3. Manual Start
