Water in Agriculture

Oxygen is an essential macro and micro element required for healthy plant and animal growth. Dissolved oxygen (DO) allows plants and animals to develop healthier and more robust living conditions, leading to increased nutrient uptake, improved yield and reduced growth cycles. ClaasECO Water UFB generators efficiently deliver oxygen to plant roots by saturating the water. Learn more about the benefits of UFB technology and how it is helping farmers around the world be more efficient and productive.


ClaasECO-Water UFB-nanobubble gas injection technology enables the cost effective use of oxygen to improve water quality to help promote nutrient uptake, plant health, and suppress root disease and animal well-being. It is our ability to convert bulk gases like oxygen into Ultra Fine Bubbles that gives our technology a unique advantage over traditional forms of aeration and oxygenation. For example, Ultra Fine Bubbles enable us to deliver high levels of oxygen directly to the root surface where the oxygen plays a critical role in facilitating nutrient absorption and maintaining optimal root- and plant health. Around the world it was consistently demonstrated in multiple cultivation methods and a wide variety of crops that oxygen Ultra Fine Bubbles can significantly improve plant health and resistance to environmental and pathogen stress.

Improve Nutrient Buffering & Uptake
Healthy, well oxygenated roots absorb nutrients more efficiently to better support the photosynthesis process leading to faster and more uniform plant development. Shorter growing cycles enables more crop rotations per year. Oxygen help to promote plant turgidity, improving environmental stress tolerance.

Healthier Roots & Disease Suppression
Increasing the oxygen availability in wetted substrates prevent root asphyxiation and promotes new root development. Maintaining a stable aerobic environment stimulates beneficial bacteria growth that helps to suppress pathogenic organisms like Pythium, Phytophthora, Fusarium etc. and pathogenic facultative anaerobic bacterial pathogens like Erwinia, Pseudomonas and Agrobacterium from proliferating.

Enhance Growth & Less Plant Stress
Healthy, well oxygenated roots absorb nutrients more efficiently to better support the photosynthesis process leading to faster and more uniform plant development. Shorter growing cycles enables more crop rotations per year. Oxygen helps promote plant turgidity, improving environmental stress tolerance.

Water Quality Improvement & Biofilm Control
Supersaturation with oxygen Ultra Fine Bubbles suppresses water-borne pathogens by competitive exclusion instead of relying on stronger oxidants that can damage plant roots. Ultra-Fine Bubbles are an effective treatment for controlling algae and biofilm that can cause irrigation line blockages.


Over half of the fish and shellfish directly consumed by humans are produced through aquaculture, also known as fish farming. As fish farmers look to produce more fish to keep up with global demand, they run into severe problems with a lack of dissolved oxygen (DO) in the water. Fish and shellfish need oxygen to breathe. When fish populations are tightly packed, a shortage of DO is inevitable because the fish and shellfish consume more oxygen from the water. Additionally, waste by-products accumulate on the bottom of the fish farm, damaging or eliminating bottom-dwelling plants and animals. ClaasECO-Water UFB-advanced gas-to-liquid injection technology can alleviate these problems by rapidly elevating and maintaining higher levels of DO levels in the fish farm and effectively oxygenating sea floors due to the Ultra Fine Bubbles lack of buoyancy.

Stock Density
The metabolic rates of fish can be severely affected by the concentration of oxygen in the farm. Low DO levels lead to decreased respiration and feeding activity that slow fish growth rates. An oxygen saturation level of 85% and above is ideal for aquaculture; lower levels have varying effects on the fish and molluscs, ranging from reduced appetite to massive mortality rates. Oxygen aeration using the ClaasECOWater Ultra Fine Bubble generators ensures that fish farmers can achieve the highest possible stocking densities while ensuring high survival rates to boost yields and profits.

Disease Prevention
Low DO levels in the water of an aquaculture farm can also lead to disease through bacterial and fungal infections. A lack of DO can lead to a build-up of fish and mollusc waste on the bottom, creating conditions that are ideal for bacteria and fungi to thrive. Farmers have traditionally turned to vaccination, antibiotics, or additive chemicals to deal with these issues. However, these methods are costly and cause great stress to the fish, making them less healthy for human consumption. ClaasECO-Water UFB-nanobubble technology uses the power of clean and natural oxygen delivered through neutrally buoyant Ultra Fine Bubbles to prevent disease, providing a much healthier, efficient, and cost-effective solution for aquaculture.

Efficient Oxygen Transfer
Aquaculture farmers need large quantities of oxygen to maintain a healthy fish and mollusc population. Failure to add any additional oxygen to the water will lead to poor growing conditions and is not a feasible option. Traditional aeration methods are very inefficient, leading to high costs to achieve proper DO levels. ClaasECO-Water UFB-nanobubble generators is the ideal technology to maximize oxygen utilization for the aquaculture industry by delivering the highest oxygen-transfer efficiency, over 90%, of any aeration method on the market today.

Food Safety

Spoilage and contamination of food wastes millions every year. Pathogens (bacterial and fungal), viruses, and chemical residues can pose major health risks to consumers. These health risks have given rise to a sophisticated food safety industry that focuses on the handling, preparation, and storage of food in ways that can prevent spoilage and food-borne illness caused by bacteria, viruses, mould, and fungi. Common treatment methods include costly chemicals and pesticides that are not suitable for human consumption. Another form of treatment is through the use of oxygen, ozone, and carbon dioxide (CO2). ClaasECO-Water UFB gas-to-liquid injection technology efficiently delivers oxygen (O2) or ozone (O3) to the treatment process, providing a natural alternative to chemicals and pesticides.

The persistence of pathogens like the norovirus in oysters or E. coli, Salmonella, Listeriosis etc. in meats, vegetables, fruit and other foodstuffs present a significant challenge to food processors. Sickness or death from consumption of contaminated food is preventable. Chemical treatments are not desirable and can affect taste and quality of products as well as disease causing residues. Ozone and oxygen Ultra Fine Bubbles have been demonstrated to be highly effective in eliminating these pathogens while simultaneously enhancing shelf life. Additionally, the negatively charged Ultra-Fine Bubbles help remove and destroy organics and pathogens from the surface of food.

pH Adjustment
While the use of CO2 for pH adjustment is common in various industries, the advantage of using the ClaasECO-Water Ultra Fine Bubble generators is its high transfer efficiency, which exceeds 90%. Rather than losing the bulk of the gas through off-gassing as in a traditional system, ClaasECO-Water UFB equipment converts the bulk of the gas into Ultra Fine Bubbles that remain in suspension for significantly longer periods of time, creating a more effective and efficient pH-regulating method.

Cleaning & Pesticide Removal
Produce-washing tanks can be injected with oxygen Ultra Fine Bubbles and ozone to help generate hydroxyl radicals. The combination of these oxidizers in solution has been demonstrated to be very effective at breaking down volatile organic compounds like phenols, which are commonly found in pesticide and herbicide residue on produce. Ultra-Fine Bubbles can also replace the use of cleaning chemicals. Trillions of Ultra Fine Bubbles smaller than 200nm in size are effective at removing particulates from the surface due to their negative charge.
