ABSTRACT:
A treatment apparatus and system for treating small batches of waste material from a septic tank or holding tank of a portable restroom service truck. The apparatus includes at least one processing tank capable of holding a small batch of waste material. The processing tank is designed to function as a processing tank in which oxidation of the waste material occurs and as a separation tank in which the oxidized waste material is separated into sludge and waste water. The processing tank has an upper section and a lower hopper section with a discharge pipe attached to the hopper section. Viewing ports are manufactured on the front surface of the processing tank which enables the operator to determine the amount of waste material placed inside the processing tank and to view the oxidation and separation processes occurring therein during treatment. A mixer is also provided which is used to mix the waste material. The system includes the apparatus along with a safe, inexpensive, easy-to-use oxidizing agent, such as sodium hypochlorite, hydrogen peroxide, and calcium hypochlorite, and a flocculating agent.
