Microscreen Drum Filter Tertiary Polishing Plant

WPL Clic-Clo Microscreen’s are typically used in municipal and industrial applications to mitigate the risk of compliance failures.

They are widely used for the reduction of Biochemical Oxygen Demand (BOD), Total suspended solids (TSS) and chemical precipitates, such as that generated in phosphorus precipitation. WPL Clic-Clo microscreens have been successfully applied to municipal and industrial applications in the UK and Europe.

The following can be achieved when the microscreen is being used in tertiary municipal applications, with a 40μm filtration cloth:

  • BOD removal 60%
  • TSS removal 30%

WPL Cli-Clo Microscreens are also available as skid mounted options or hire or pilot trials to ensure suitably for a client’s need before purchase.

 

Why you should choose the WPL Microscreen:

Efficient

  • Mitigates the risk of compliance failures.

Small footprint

  • Up to 32 L.S-1/m2 of filter footprint area.

Adaptable installations

  • Fully integrated treatment package for adaptation in to existing process streams – above and below ground.
  • Choice of Form 2 or Form 4 control panels – to accommodate particular electrical specifications and can be connected to telemetry.

Low power consumption

  • Typical 20 l/sec typical application consumes <0.3kw/hr.
  • Unique design of the drum filter maximises the surface area of the filtration cloth to ensure high removal efficiencies.

Low maintenance system

  • The patented ‘Cli-Clo’ system allows filtration cloth segment replacement, rather than an entire cloth.
  • No chemicals required for maintenance requiring minimal weekly checks.
  • Polyamide or stainless steel cartridges can be utilised – stainless steel is more suitable to some applications where polymer dosing is taking place upstream.
  • Interchangeable cloth cartridges available from 20 microns upwards to provide flexibility on flow vs flux and cater for more stringent solids consents.

Compliant

  • CE marked and built to European norms.

Typical applications:

  • Tertiary, municipal wastewater
  • Tertiary, domestic wastewater
  • Phosphorus precipitates removal
  • Paper mills
  • Textile manufacture
  • Breweries and wineries
  • Fish production

 How does a WPL Clic-Clo Microscreen system work

The WPL microscreen combines physical screening and solids collection/extraction. This is most commonly used as a tertiary screen to ensure TSS compliance on overloaded municipal and industrial sites. The figure below shows the functional areas of the WPL Clic-Clo Microscreen:
