SAFETY INSTRUCTIONS
Read This First
It is the responsibility of the contractor, the installer, and the owner to maintain and operate the
equipment supplied by ANDRITZ in such a manner as to comply with the laws concerning
occupational safety and health, as well as with all national, state, and local laws and ordinances.
Consult the local safety standard authorities or plant supervisors for a complete listing of these
regulations.
Safety must be considered a primary factor in all aspects of equipment installation, operation, and
maintenance, at all times. Safety training and equipment maintenance will be covered by
authorized ANDRITZ personnel prior to startup of the equipment. All operating personnel will be
advised of the location and operation of all emergency control devices.
The following safety instructions are basic guidelines and should be considered minimum
provisions:
 Unobstructed access to controls and emergency stop devices must be maintained at all times.
Sufficient lighting and good housekeeping practices must be maintained around the equipment
at all times.
 All rotating equipment — such as drives, gears, fans, pumps, shafts, couplings, chains, belts,
and ropes — must be guarded as required by the applicable laws and standards. The equipment
must not be operated until all covers and guards are in place.
 If equipment is to be opened for inspection, maintenance, or servicing, the drive motor must be
locked out and secured against being switched on again (lockable repair switch, shorting bar,
and the like). Equipment operation must not resume until all covers and safety guards are in
place.
 High-voltage and rotating electrical machinery can cause serious or fatal injury. Installation,
operation, and maintenance of rotating electrical machinery must be performed only by qualified
personnel.
 Inlet and discharge openings must remain connected to other equipment so that dangerous
parts of the machinery are not exposed.
 Warning signs must not be removed. If warning signs become dirty or damaged, they must be
cleaned or replaced immediately.

CHAPTER 1
EQUIPMENT DESCRIPTION AND
DESIGN CRITERIA
1.1 EQUIPMENT DESCRIPTION
1.1.1 General Description of the Aqua-Screen®
The Andritz Aqua-Screen® is a continuous perforated plate system designed to extract solids from
all types of channels. Flow capacity depends on screen width, perforation size, the open area of
the perforated panels, and the upstream level in the channel. Each screen is designed to suit
prevailing hydraulic conditions and can be operated manually, on a timer, or in fully automatic
mode with level controls.
The Andritz Aqua-Screen® uses close fitting perforated plates to remove floating and suspended
solids (screenings) in the effluent flow. The panels are shaped to form steps, which are carried on
heavy-duty chains protected from the ingress of debris by a bottom polyester bristle sealing brush,
stainless steel side plates, and flexible seals.
The captured screenings are elevated from the effluent channel on the stepped perforated plates
over the top of the Aqua-Screen®, and ejected through a totally enclosed discharge chute. The
continuous perforated plate is cleaned in two stages:
Back washing using a high-pressure spray bar (or low-pressure deluge).
A rotary washing brush that removes any remaining debris, including fatty and fibrous material.
The rotary washing brush is mounted on pivoting plates that are adjusted to compensate for wear.
The tail end runner has no bearing and is made from a wear-resistant material requiring no
maintenance. This means that normal maintenance is carried out above ground.
