The patented Contra-Shear Suboscreen ®
and integral screening removal system
provides the following features and benefits :
Low, known consistent Headloss
* Consistent clean
screenings area maintains
constant flow velocities.
* Large effective
screen area for machine size.
* Headloss based on actual
site measurements
of multiple installations with a variety
of effluents.
Typical Industry Applications:
- Sewage
- Brewery
- Dairy
- Food Processing
- Chemicals
- Pulp & Paper
- Storm Water
- Agriculture etc........

High solids capture rate
* Screening drum
slots at 90 deg to the flow
for enhanced solids capture and
separation efficiency.
* Optimal and
Constant flow velocities
maintain maximum solid capture rate.
* Optical
measurement of the Vee-wire®
slot
size ensures accurate screenings recovery.
* Integrated design
ensures no effluent leakage.
* High fibre
recovery due to influent flowing
normal to the screen surface.
* Vee-wire ®profile
selected to discourage
stapling and screen blinding.
Large flow capacity
* High effective
screen area compared to
machine size.
* Screens mounted
horizontally in channel.
* Standard units
with capacity upto
300 ML/day in single unit.
* Flexible design
for optimized configuration
and cost effective layouts.
Operating Process:
The influent enters the in-line, in-channel,
semi-submerged screen undergoing a 90 deg. change in direction as it flows
through the Vee-Wire slots for further processing. critical to the screens
consistent performance is the wash sparge system which ensures that a clean
screen face is always presented to the influent stream. This is provided by two
external sparges generally supplied with screened effluent to conserve water and
reduce cost. The solids captured by the screen are transported by the drum
rotation and lifting staves and are deposited in the discharge flume. water is
used to transfer the screenings to the integral Drainer Screw Press where they
are Drained-Transported-Compacted & Discharged.
Screw Press :
Various sizes of screw press are available to
convey the solids and remove water to give out drier solids for easy handling.
