Superior oxygen transfer

NANO BOT® aerator is specifically designed to incorporate the technology of NANO TUBE® aeration tubing and our diffuser grids into a complete aeration system. The NANO TUBE® was developed to bring the superior oxygen transfer efficiency of NANO TUBE® to pond and raceway based systems while also offering the deep mixing of the water column traditional aeration like paddle-wheels lack.

Energy conversion efficiency

The NANO TUBE® allows you to control the water circulation while giving you unmatched energy efficiency in aerating your system. Many of the traditional aeration devices like paddlewheels, air jet, and aspirator style aerators have a poor track record of reliability and higher overall energy requirements. By utilizing NANO TUBE® technology, an NANO BOT® solves both of these problems.


Producing natural microbes

NANO BOT®'s breakthrough technology is able to treat all kinds of organic waste including residential, commercial, industrial and municipal sectors. It can be effectively used in natural waterways such as rivers, lakes and bays. Unlike other water cleaning treatment systems, NANO BOT® constantly produces its own good microbes, eliminating the need to add new microbes everyday. The microbes are all-natural and have not been genetically modified. They are safe from pathogens or from the risk of mutation. Only microbes classified by the US Center for Disease Control and Prevention (CDC) as BioSafety Level 1 are used in the NANO BOT®.

NANO BOT® vs Paddle Wheel reports

A study comparing the water movement and mixing capabilities of a 1 Hp NANO BOT® and a 1 Hp Paddle Wheel.

Equipment used:

1/ 1 Hp NANO TUBE® (3-Grids)
2/ 1 Hp PaddleWheel

Pond dimensions:

Area: 0.4 hectare (4,000 m2)
Depth: 6 feet (1.83 meters)


1. Both the 1 Hp NANO BOT® and 1 Hp Paddle Wheel were started 5 minutes before the dark purple dye was released into the ponds at the exact same time.

2. The coverage of the dye in the pond was then compared at certain time intervals - 18 mins, 30 mins and 55 mins

Outcome (18 minutes):

Observation: Both the NANO BOT® and the Paddle Wheel are able to move the water well in the pond.

The colour of dye coverage in both ponds are dark purple.

Status: 18 minutes after dye release in both ponds

Outcome (30 minutes):

Observation : Both the NANO BOT® and the Paddle Wheel are still moving the water at the same rate with similar coverage of dye in the pond. The colour of dye coverage in both ponds are still dark purple.

Status: 30 minutes after dye release in both ponds

Outcome (55 minutes):

Observation: Both ponds are completely covered with dye. However, there is a noticeable colour change in the pond using the Paddle Wheel.

For Paddle Wheel: The dye had sunk to the bottom of the pond.

For NANO TUBE®: The dye is continually brought to the surface of the water.

Status: 55 minutes after dye release in both ponds


1) Both NANO TUBE® and Paddle Wheel were able to circulate the water at similar rate.

2) However, the NANO TUBE® was able to provide better vertical mixing, bringing the water and aeration from the bottom of the pond to the surface.

Hence, that would mean more aeration for our aquaculture species across the entire pond.

NANO BOT® vs Paddle Wheel result testing

Paddle Wheel Aerator NANO BOT®
1/ Heavy splashing on the top layer of the pond leads to unequal temperature and DO in pond bottom. 1/ Can able to aerate pond water deep 1-4 meters or even deep. Circulates oxygen rich surface water by destratifying pond water column. This ensures uniform pond temperature and oxygen levels throughout the pond
2/ Many moving parts and questionable workmanship leads to high mainteinance and repair costs 2/ Using regenerative blower requires no additional lubrication and very low maintenance
3/ Reducer gearbox design requires constant lubrication and frequent replacement 3/ Special design can make water flow and mix water well from parallel and vertical direction
4/ Many parts and made of galvanized steel, aluminum and low grade stainless steel - all of which corrode quick in pond environment 4/ NANO BOT® is made of injection molded PVC plastic, float made of HDPE, frame made of stainless steel , long lifetime
5. Only able to aerate shallow ponds 5/ Maximum of naturally produced oxygen
6/ Relatively poor SAE 1.3 - 1.7 kg O2/kw 6/ High SAE with 4.2 - 9 kg O2/kw

NANO BOT® in the nursery ponds

Low dissolved oxygen is the most common cause of fish kills in ponds. Contrary to popular belief, fish kills are never caused by natural over-population. A pond will naturally stay within its capacity to support fish under normal conditions. The NANO TUBE® also delivers a very efficient amount of oxygen to the water transferring 3.6 Kgs of oxygen per hour, enabling the microbes to have a good source of oxygen.

NANO BOT® in the shrimp nursery pond

NANO BOT® in the shrimp farms

Oxygen improves the growing of shirmp, tilapia, biomass by supplying oxygen needs on a 24/7 basis because the oxygen supports the aerobic digestion of all foods whenever the tilapia needs or wants to eat. The supplying of oxygen to intensive growing systems has been accepted for many years, but the idea of supplying oxygen to dirt ponds has only recently been looked at. As a general rule, 1 hp of electric aeration should be available for each surface acre (4 acre feet) of intensive aqua culture production. Aeration equipment should be placed along the longest pond bank. Aerators should be started before DO falls below 3 mg/l

NANO BOT® in the fish farms

In outdoor ponds, oxygen depletion events can occur at anytime, however, they are most likely to cause fish kills during hot summer weather. A decrease in oxygen production is caused by incidents such as cloudy weather and plant or algae die-offs that shut down photosynthesis. Heavy populations of plants or algae are the most important producers of oxygen in the system.

Wastewater lagoons

The NANO BOT® is a good solution for reaeration of freshwater lakes, lagoons and reservoirs. Our NANO BOT® provides for enhanced or additional treatment of cBOD (Carbonaceous biochemical oxygen demand) and nBOD (Nitrogenous Biochemical Oxygen Demand) in lagoon processes.
