Low Speed Surface Aerator - Changzhou Rongda

    LSGB Vertical Low Speed Surface Aerator can be used in the biochemical treatment of municipal sewage and industrial wastewater. Through the powerful rotation of the impeller, it can agitate the water to complete the process of casting, liquid surface renewal and aerobe transmission, increasing the speed of oxygenation. The LSGB vertical Low Speed aerator is especially suited for oxidation ditch process due to its function to produce the water screw propulsion effect.

Product Code: LSGB Vertical Low Speed Surface Aerator

Impeller Structure Type: S, C, D

Impeller Nominal Diameter: cm

Control Mode: Variable speed (B); Constant speed (H)

For example:

Motor power: 132kW, Impeller Nominal Diameter: Ф3250mm, Impeller Structure: C, Constant Speed

It can be annotated as LSGBC325H- 132

This equipment receiving the national invention patent . Its characteristics are as follows:

1、Efficient and Energy-saving

The quality dynamics characteristic of mass transfer makes the power efficiency exceeLSGB the industry standard of 12.4%.

2、Stable and Reliable 

It’s smooth in operation, high-efficient in transmission and coefficient of service more than 2.0.

3、Intense Agitation

The invented impeller has the functions of aeration, agitation and propulsion so that the effective water depth is greatly improved in the oxidation ditch, which can reduce an area of 15% ~ 40%.

4、Optimized structure

The Installation of platen can ensure the installation level degree of aeration. The drives are over the water, making the maintenance convenient.

5、Diversified control

According to the nee LSGB of technology design, the aerator can operate either by constant speed or by variable speed, obtaining the needed oxygenation rate through the devices of frequency conversion and speed control and achieving the best economic operation mode.

Specifications and Technical Parameters

    The shape of the pool changes with different impeller structures. In parameter table, Widest ditch and deepest water are normal shape of ditch, they are for reference.
