There are over 100 different patents governing Aerobic Treatment Units (ATU) and each one is slightly different in the way it operates and what equipment it uses. Basically, the common denominator between all of them is they inject oxygen into the tank to aid in the breakdown of the solids. By aerating the solids they break down the solids faster but they do not consume the solids so they may have to be pumped more often to maintain their optimum breakdown ability. Because air is introduced into the tank the air has to be released through a vent somewhere. This may cause an odor problem depending on where the vent is. ATU’s are very good septic systems that can benefit greatly from the use of TankTechsRx for Septic Systems. The air introduction with our product will enhance the consumption of the solids and remove the odor. Because TankTechsRx for Septic Systems consumes the solids leaving only liquid that is beneficial to the environment frequent pumping of sludge will be unnecessary and possibly eliminated entirely in some systems. An added bonus is it will enhance the work of the leach drain keeping it at peak operating performance.
