Description

Aquasust MBBR Mixer

Low-speed push flow series products use cycloid reducer, equipped with small power, low speed, large impeller diameter, wide service area. The impeller is made of polyurethane material and aluminum alloy, with high strength and corrosion resistance, which can push the flow and create water flow in addition to the function of mixing.

Low Speed Mixer Performance Parameters

Aquasust MBBR Mixer are designed in such a way that they have an exceptionally large, inner surface area on which the bacteria can grow without being knocked off or otherwise destroyed when they rotate and hit each other.

Aquasust MBBR Mixer Feature:

1.Lower Impeller Speed: The mixer has a lower impeller speed, only 106 revolutions per minute (r/m), compared to the typical 400 to 1000 r/min of a submersible mixer. This slower speed, approximately 10 to 20% of the typical speed, is tailored to meet the specific process requirements of the bio-carrier tank.
2.Large Diameter Three-Leaf Blades: The mixer features large diameter three-leaf stainless steel blades. This design is carefully selected to meet both hydraulic and biocarrier process requirements within the tank. The size and material of the blades contribute to efficient mixing and durability, important factors in wastewater treatment systems.
3.Self-Cleaning Propeller: The propeller is designed for self-cleaning functionality. Constructed from stainless steel material, it not only ensures durability but also incorporates features for automatic cleaning. This design consideration enhances the longevity and effectiveness of the mixer in maintaining optimal performance over time.
4.Versatile Installation System: Equipped with an installation system developed by Aquasust, the mixer can be installed on the equipment from multiple angles. This flexibility in installation enables efficient and adaptable integration into various configurations of the bio-carrier tank, optimizing space utilization and overall system effectiveness.

Aquasust MBBR Mixer in Desalination plants Application

1. Keep filler in suspension

The primary task of the MBBR agitator is to keep the filler suspended in the water. Through uniform agitation, it prevents filler deposition and ensures that biofilm grows uniformly on the surface of the filler, thus increasing biodegradation efficiency.

2. Promote oxygen transfer

Agitators effectively mix air and water to increase the concentration of dissolved oxygen in the water. Adequate oxygen supply is critical to the aerobic biodegradation process and directly affects the pollutant removal efficiency.

3. Uniform distribution of pollutants

Through agitation, pollutants can be evenly distributed in the reactor, thus ensuring that each biofiller can reach the pollutants and improve treatment results.

4. Prevent dead zone

Proper agitation prevents dead zones in the reactor and ensures water mobility throughout the reactor to avoid localized inefficiencies.

5. Maintain appropriate biofilm thickness

The agitator helps to control the thickness of the biofilm, avoiding the increase of mass transfer resistance caused by the over-thickness of the biofilm, so as to ensure the biofilm's activity and treatment capacity.

6. Reduce short-circuit phenomenon in the reactor

Effective agitation can minimize short-circuiting, ensure the hydraulic residence time of the reactor, and improve the overall treatment efficiency.
