Bubbles are all around us, in our foods, beer, pop drinks bread and cheese, but also in the bricks of our house. Bubbles are gas-filled cavities in water, the lifetime of a bubble is short at most a few minutes, only ultra-fine bubbles are stable for longer periods like months, that is making them very special and that enables us to change the properties of water.

Water is one of the fundamental components of life. A large part of living cells is made up of water. Birds need twice as much water as the food they eat. To satisfy the need for water in poultry and birds, you must make water freely available to them. Note that the unavailability and limitation of water consumed by poultry slows down their growth. The water used in poultry feeding should not contain parasites, bacteria, pollution or chemicals, and fresh and clean drinking water must be provided. Bacterial agents are one of the most common water-borne infections. Drinking contaminated and untreated water can cause huge losses in the poultry industry. Using chemicals and antibiotics to disinfect drinking water can cause health problems and drug resistance in chickens. In the last decade, researchers have tried to find a suitable alternative to disinfect and improve the quality of drinking water for farm animals, especially chickens. One of the most available and best options is oxygen-nanobubbles water. By providing oxygen- nanobubbles water, the growth and development of chickens increases, and on the other hand, it enhances their resistance against microbial infections. In this article, we evaluate the benefits of oxygen-nanobubbles water in the poultry industry.
Oxygen plays an important role in plant respiration, which causes energy production and plant growth. Increasing the percentage of oxygen in water improves the root structure and the activity of useful microbes in the rhizosphere. Naturally, an effective and practical system can increase productivity by improving the quality of irrigation water and increasing dissolved oxygen in irrigation water. Acniti oxygen concentrator and Acniti turbiti O3 are very effective supplements for irrigation of agricultural fields and at the same time improve water quality and increase dissolved oxygen (DO) and ozone in irrigation water. To determine the role of oxygen and ozone nanobubbles in the growth of lettuce, an experimental research was conducted. Research showed that by using Acniti nanobubbles generators, will increase the level of dissolved oxygen in water, and makes the roots of lettuce grow more and its weight increases significantly.
