Screening
Fine screens are used to separate solids from urban or industrial
wastewater.
Application and operation of the fine screen :
ROTOSCREEN and MONOSCREEN (fine screens - manufactures
by MEVA) are constructed as an alternating assembly of fixed
and moving blades- comparable with an escalator.
With each rotation, the action of the moving blade, elevates
the screened product to the next step. This function is repeated,
" step by step " until the product reaches the discharge
point at the top of the screen.
The operation is cyclic and is usually regulated by variations
in upstream water levels caused by progressive " blinding
" of the screen face.
The degree of screening can be from 1 to 6 mm.
