Product Description
Introduction
The high-speed aerator line is designed to maximize the two most important functions of any aeration device-oxygen transfer and mixing of
wastewater . The waste liquid is pumped through the unit in a manner which creates the most optimal spray pattern to facilitate oxygen into the wastewater . At the same time, this pumping action creates a tank velocity pattern which ensures the mixing of contents and thus the oxygen dispersion. Years of experience in the design and application of mechanical aeration equipment, combined with the full capabilities
of our extensive research test facility, enabled us to provide a line of high speed aerators which not only maximizes oxygen transfer and tank
mixing characteristics but also achieving this in the most economical and reliable way.
Applications
GSD' s surface aerator (SAR) uses a motor to directly drive the axial flow impeller, which discharges the waste water from the conduit through the water deflector and forms a thin (or water drop-shaped) water curtain. When contact with air during the transfer, it will form water drop shape, which fall to the water surface and form the turbulence and bubbles. These bubbles will improve oxygen dispersion and increase oxygen in water. The GSD SAR device pumps water from the bottom to the top and creates circulation flows and stir processes. It is suitable for domestic waste water treatment, agriculture and aquaculture oxygen supply and other industrial waste water aeration appli
cations.

Selection of aerators for Oz transfer
This chart will help to select the required horsepower of aeration if the BOD (mg/l) and daily flow rate of wastewater are known. First, select the appropriate daily waste flow on the left side of the chart. Then extend a horizontal line to the right until you intersect with the appropriate BOD curve. Drop a line vertically from the intersection to the bottom and read the horsepower required for aeration.

Construction introduction
Surface aerator consists of motor, driving shaft, axial-flow type impeller, and floater. The motor and impeller are coaxially connected and rotate at constant speed. The floater supports the entire body.
Motor and shaft: The electric motor is installed above the water spray range, which is TEFC type, F class insulation, 3ø, 50hz/60hz, the protection grade is IP56. The shaft is made of stainless steel.
Impeller: The impeller is made of stainless steel. The impellers are uniquely designed to achieve maximum hydraulic transmission while motor is guaranteed to be free from over-load. Floater: The floater body is made of reinforced fiber glass, inside of which is filled with high density polyurethane (PU) foamed plastics. The mooring holes transfer tensions among the mooring cables.

Surface aerator installation precautions
nstall the SURFACE AERATOR in the proper position according to the characteristics of the SURFACE AERATOR and the size of the pool. Check the fixing steel wires for the SURFACE AERATOR are completely fastened and the Flotation Unit is in an inclined state. Ensure the electric cables for the SURFACE AERATOR are properly fixed. In general, one of the electric cables is fixed with a hanging ring on the fixing steel wires according to the on-the-spot situation to prevent the wiring terminals from being damaged due to excessive pulling force of the electric cables. Check the for voltage and frequency of the power supply for the acceptor and make sure they are consistent with the marking on name plate of the SURFACE AERATOR.
Surface aerator operation precautions
Check the voltage and frequency of the power supply for the acceptor, make sure they are consistent with the marking on the name plate of the SURFACE AERATOR.
Ensure the capacity of the protective device for the control disc is consistent to the hp(kW) marked on the name plate of the SURFACE AERATOR in order to protect the operating lifetime of the SURFACE AERATOR.
During operation, the control disc should be switched to the "AUTO" position, not on the "MANUAL" position. The purpose of this is to automatically trip when the load is too
large.
Make sure the operating electric current is within the rated current range marked on the name plate of the SURFACE AERATOR during operation.
