ABSTRACT:
An improved method for processing multiple small batches of waste material from different collection sites is provided. The method uses an apparatus designed to process small batches of waste material from a collection site, such as a septic tank, into waste water and sludge material. Using the apparatus, the waste material first undergoes oxidation with an oxidizing agent and separation with a flocculating agent. After the oxidizing and separating steps are completed, the waste water is then drained from the apparatus and returned to the collection site. The sludge material produced is then transported to a second collection site. The waste material from the second collection site is then added and mixed with the sludge material produced from the first small batch of waste material. The new waste material is then oxidized and separated into waste water and sludge material. The waste water is then drained from the apparatus and deposited into the collection site. This process of collecting and processing multiple small batches of waste material is repeated until the maximum capacity of the apparatus or hauling truck is reached. At that time, the collected sludge material is then transported and deposited at a suitable waste water treatment facility.
