the pumps up to three times a week to clear out the
materials plugging the pumps. You have no idea how
much easier our jobs have gotten since we added the

Hydronic Series Trash Rakes
Hydraulically operated, the Hydronic T Series Rakes
telescoping boom and rake mechanism cleans coarse
and fne bar screens, trash racks and intake screens. Its
telescoping design requires less headroom, resultingin savings or indoor headworks with deep channels
or when retroftting existing screens. And because the
Hydronic T Screen does not require guides, sprockets
or chains, all moving parts can be accessed rom above

The Hydronic Type K Series Trash Rake is hydraulically
operated and capable o cleaning screens up to a depth
o 100 eet. The articulating design gives the rake arm
a long reach suitable or manual surace skimming

Horizontal Series Trash Rakes
Hydronic Horizontal Trash Rakes are used to clean racks
with horizontal bars. The hydraulically operated rake
pivots into the rack and then moves sideways to clean
the rack. The screenings can be washed away at the end
o the rack or collected using a grab rake.
HY-TEC S creen
Lakesides proven technology is apparent in the
HY-TEC Screen, which eatures combs with uniquely
shaped teeth to clean the horizontal bar rack whileretaining solids in the main ow stream. Mounted on
a hydraulically driven rame, the combs move back
and orth during a cleaning cycle that is initiated at a
preselected liquid level or head dierential. HY-TEC CSO
Screens are ideal or a number o applications, including
wastewater bypass, combined sewer overow and
storm sewer overow.

Catronic Series Trash Rakes
With a rack cleaner that is highly efcient or heavy-

cable positions the rake or cleaning. Catronic Series
Trash Rakes provide an efcient method or cleaning
intake structures up to 200 eet deep and 600 eet wide.
Monorail Series Trash Rakes
The Monorail system is designed specifcally orwastewater treatment plants, stormwater acilities and
water intake structures. It combines screening and
transporting into one unit with an overhead monorail,

Raptor Complete Plant
The Complete Plant screens inorganic solids rom
municipal wastewater and removes grit as well. The
Complete Plant can be installed either above or below
ground in its abricated stainless steel tank. As an
option, the grit chamber can be equipped with a grease
trap operated manually or with a motorized skimmer.
Simple design and operation minimize maintenance costs Stainless steel resists corrosion and increases service lie Major components are pre-assembled, minimizing
construction costs

Abrasive grit is the enemy o all mechanical equipment, reducing digester and/or aeration tank volume, clogging piping
and treatment units and increasing wear on pumps and valves. Lakeside oers simple, low cost methods to remove grit
eectively and enhance plant perormance, reducing overall operating costs.
Highly efcient Perorms in all ow conditions
SpiraGrit and Type W Grit Classier
SpiraGrit
The Lakeside SpiraGrit Vortex Grit Chamber eectivelyremoves inorganic grit rom treatment plant inuent in
a mechanically induced vortex environment. It operates
efciently over a wide range o daily ow rates. Rotating
paddles maintain the ow velocity in the vortex chamber,
keeping organics in suspension while allowing heavier
grit to settle at the chamber oor. The settled grit moves
through the center opening and into the lower grit
hopper, where it is removed by either an air lit, a recessed
impeller or a sel-priming grit pump and sent on to the
Grit Classifer.
Space-saving compact design
Aeroductor
With the Lakeside Aeroductor, air is injected into aneductor tube located in the center o the basin, creating
a vertical pumping action. The resulting circulation keeps
organics in suspension and allows the heavier grit to
settle at the bottom where it is scoured, washed and
collected in a central hopper.
