SC-LK series - submersible aerator-mixers
Pressurized submersible aerators for wastewater
treatment in municipal, industrial and agricultural
treatment plants.
DESCRIPTION
The submersible SC-LK aerator is a new aeration system
for the wastewater treatment plants working through a
submersible gear motor, whose basic structure consists
of: motor, reduction gear, aeration channels and
impeller.
All these components are made with top quality materials,
whose production technologies are in compliance with the
European standards.
The possibility to use a double speed motor enables the
machine to work as a mixer, too, thus maintaining a
correct water moving, which is very useful during some
purification stages.
APPLICATION
The SC-LK aerators are especially well-suited for deep
basins and high oxygen transfer rates in the following
processes: Oxidation, Sludge stabilization, Flotation,
Ozonation.
The ease of installation afforded by these aerators
means that tanks do not need to be emptied; their
ductility ensures high oxygen transfer values, simple
use and, thanks to a correct design, the temporary plant
stop in order to carry out maintenance.
OPERATION
The aerator consists of a star shaped impeller directly
connected with the gear motor shaft, a stator with legs
surrounding the impeller, upward folding channels and an
air pipe for the connection of the proper pipe/hose
projecting over the liquid to be treated.
The pressurized fine-bubbled air is radially distributed
and diffused in a rapid water flow, thanks to the low
rotation of the impeller.
The air/water flow is then discharged from the machine
through the square section channels, thus assuring an
efficient mixing with minimum head losses.
The remarkable speed of the air/water flow increases the
oxygen transfer efficiency between these two elements,
both in clean water (tests carried out under standard
conditions) and in wastewater (actual conditions).
The working range is divided in A zone, that is, the
principal or primary movement coming from the expulsion
channels and in B zone, which is the induced movement
able to maintain the water well aerated and mixed.
INSTALLATION
The SC-LK aerators are especially designed for
stationary installation, because are positioned on the
bottom of the basin and stand firm due to their own
weight.
The air suction pipe (or the air suction hose) is
connected above the water level either to the basin
edges or to a gangway.
The blower or the compressor is installed under a
soundproof hood or in a room of the plant premises.
You can use one blower or compressor per aerator or for
several aerators.
The aerators can be lifted out of the basin with a
mobile crane and reinstalled e.g. after maintenance,
without emptying the basin.
