Aeration
The purpose of aeration is to introduce air (and with that oxygen) into a liquid (usually water) and mix it with, or dissolve it in. Oxygen concentration in water is a prime indicator of the water quality for human use as well as for aquatic biota - artificial aeration acts to replenish the used oxygen, and has opportunities in a number of applications from wastewater treatment to hydropower discharge.
The efficiency of aeration treatment is strongly influenced by the amount of surface contact between air and water and the time of contact. The location and design of air injection systems, coupled with the size of the entrained bubbles, are therefore parameters of major importance which have to be considered when developing an efficient aeration product.
Energy cost is also an important issue - the more efficient the oxygen transfer the less power required to provide similar quality of aerated water. This is a key concern for end users with ever increasing energy costs and security of supply issues threatening compromise of increasingly stringent environmental regulation.
A rapidly rising demand for energy saving products is therefore challenging process supply companies, with energy consumption becoming the main technical challenge.
Uniquely Hydroventuri technology requires little or no energy input for effective aeration - thus significantly reducing not only whole life treatment costs but also decreasing the carbon footprint of the operator.
