DEFINITION OF SCREENING

 

Screening plants face nature. There is, as a result, a measure of uncertainty as to what they have to handle, and a safety margin is needed.

 

Screening is a filtration process which separates solids from liquids. It has two purposes:

 

  1. To clean the liquid

  2. To recuperate / protect the solid matter

 

Mechanical water-screening uses self-cleaning devices (static and dynamic) to screen water; this allows clean water to be used industrially while at the same time collects and protects valuable water life.

 

 

LAYOUT

 

While every screening plant is a special design which copes with local factors, the general layout is always the same:

 

  1. STOPGATES, STOPLOGS or PENSTOCKS are always provided for pit dewatering purposes. They have metal, grouted-in guides.
     

  2. BAR SCREEN RACKS are provided with bar intervals from 20mm to 50 mm (2”), or more. Provisions for raking are always made and the rakes are installed whenever they are needed. Fixed head rakes are preferred to travelling raking heads for seawater intakes where trash surges are generally brutal. Full automatic operation is provided.  
     

  3. The MECHANICAL SCREEN comes next. It is either a travelling band screen or a drum screen (dual-flow or thru-flow types).
