aerator

Aerators are essential equipment for aeration and oxygenation in water supply and drainage systems. They can be divided into surface aerators and underwater aerators according to their usage methods. Underwater aerators mainly include microporous aerators and jet aerators. There are several commonly used microporous aerators:

Hanging chain aerator

The oxygenation efficiency and power efficiency of the equipment are improved compared to ordinary microporous aeration equipment, and maintenance is simple. It can be repaired and damaged aerators can be replaced without affecting normal operation (without stopping water or gas supply), which is practical and reliable.

Product specification: Φ 65

Technical parameters: Water depth: 4.5m; Service area: 2m2/m; Ventilation rate: 8 m/m.h; Oxygen utilization rate: 30.36%; Power efficiency: 6.24 kgO2/kw. h; Oxygen supply rate: 0.68 kgO2/h; Resistance loss: 3600 Pa; Pore density: 14000~15000/m; Stroke bubble diameter: 0.5~5 mm.

Diaphragm type microporous aerator

The device has a small diameter of aeration bubbles, a small diameter of gas-liquid interface, a large gas-liquid interface area, uniform diffusion of bubbles, no pore blockage, and strong corrosion resistance. It has been tested for water and sewage oxygenation by the School of Environmental Engineering at Tongji University in Shanghai and the North China Design Institute of Municipal Engineering in China50Multiple users have been using it for many years with good results (lower energy consumption compared to conventional products such as fixed spiral aerators, diffuser aerators, and perforated tube aerators)40%, or increase the sewage treatment capacity40%）. Especially suitable for urban sewage and the construction and expansion of large factories, as well as the renovation of old aeration tanks, and the aeration tanks can operate intermittently.

Main technical parameters:　

The thin wall and straight passage of this aeration hose greatly reduce the loss of aeration resistance; The variable hole and slit automatically close, completely solving the problem of blockage in the aerator; The hose is designed with linear aeration to ensure more uniform air distribution and create vertical circulation, resulting in more even mixing and agitation; Small bubbles, high oxygen utilization efficiency, and high power efficiency.

Water depth of 5m, service area of 0.5-1 m/m, oxygen utilization rate of 10-16%, resistance loss of 220-500mmH2O, oxygenation power efficiency of 1.56-11.47 kgO2/kw. h.

Technical parameters: The inner wall diameter during aeration is 62.5mm, the number of air holes is 3600/m, the compressive strength is 2kg/cm, and the aeration rate is 0-15m/h · m

Pipe aerator (aeration tube):

Adopting energy-saving design, low installation cost, high reliability, and excellent performance in intermittent and continuous aeration processes.

Precision drilling is beneficial for efficient oxygen transmission and utilization: To meet the specifications of the aeration system, different drilling modes can be used to adjust the working pressure, such as different slit lengths, distances, and drilling densities.

The drilling length ranges from 200 to 1200 millimeters, with standard lengths of 500 millimeters, 750 millimeters, and 1000 millimeters. All membrane materials are designed based on nanotechnology to prevent clogging and prevent solid and biological solidification of crusts. Membrane material:

EPDM rubber: suitable for municipal wastewater treatment

Low plasticity EPDM rubber: suitable for industrial wastewater generated from animal slaughter, food processing, and beverage production

Silicone rubber: suitable for wastewater from pulp and paper industry, petrochemical and refining processing, etc

PU: Suitable for the petrochemical industry

The replacement membrane of tubular aerator (aeration tube) adopts microporous aeration membrane in the wastewater treatment industry, which has high oxygen utilization efficiency and low energy consumption. The replacement membrane is universal with most microporous aeration membrane systems.
