Overview
The VIVAMIX series VM-FB Surface Aerator is specially designed by our technical team for wastewater oxygen transfer and mixing. The equipment pumps wastewater to form high-speed jets, significantly enhancing the integration of water and oxygen, driving the water flow in the tank, and ensuring uniform mixing and sufficient aeration of the wastewater,It is ideal for municipal sewage treatment, oxygen supply for livestock and aquaculture wastewater, and various types of industrial wastewater aeration

Application areas
Suitable for lakes, rivers, reservoirs, aquaculture ponds, wastewater treatment basins, oxidation ponds, and equalization tanks - any water body that requires aeration, removal of harmful gases, and water quality improvement. It is especially ideal for sites with fluctuating water levels or where fixed installation is not feasible.
AERATOR SELECTION
For proper selection, please provide the following:
- Pond/tank surface area and water depth
- Treatment flow rate
- Desired increase in dissolved oxygen
- Type of wastewater (industrial, aquaculture, municipal)
Based on this information, we will recommend suitable power, quantity, and installation layout.
The following chart can be used for quick estimation of the required power.
When the BOD (mg/L) and the daily wastewater flow rate are known, the following chart can be used to select the required power of the surface aerator for wastewater treatment. To use the chart, first locate the desired daily wastewater flow rate on the left side and draw a horizontal line to intersect the curve representing the required BOD. From this intersection point, draw a vertical line downward and read the required power at the bottom of the chart.
This chart is based on the following conditions:
BOD removal rate of 90%
Oxygen utilization coefficient (α) of 0.8
Microorganisms consume 1.25 lbs of oxygen for every 1 lb of BOD removed
he standard oxygen transfer rate of this aerator is 3.5 lbs of oxygen per horsepower-hour
he accuracy of the chart is within ±10%

INSTALLATION METHOD
FAQ
1,Is installation complicated?
No civil works are required! The unit is fully assembled and tested before delivery. On site, it only needs to be lifted or manually placed into the water and connected to the power supply. Installation and maintenance are simple and convenient.
2,Is the energy consumption high?
Compared to traditional aeration methods (such as blower aerators), the floating aerator is highly efficient and energy-saving. For the same oxygen transfer rate, it can reduce energy consumption by 20%–30%. It can also be flexibly switched on and off according to water quality conditions, achieving even greater energy savings.
3,What materials are used? Will it rust?
The main components are made of corrosion-resistant stainless steel (such as 304/316) or engineering plastic floats, ensuring excellent anti-corrosion and anti-rust performance. It is suitable for various water qualities (freshwater or mildly corrosive wastewater) and offers a long service life.
4,How is the price calculated? Does it include shipping?
The price depends on the required power, materials, quantity, and shipping distance. In general, prices can include taxes and delivery to site. Flexible payment terms are also available.
5,Is maintenance complicated?
Maintenance is simple - only regular checks of cables, bearing lubrication, and clearing any debris from the impeller are needed. For inspection or repair, the unit can be easily pulled to shore without draining the pond or performing underwater work.
