Abstract: This invention provides an apparatus for activation of a digesting agent for an organic material, the apparatus including a tank, a device for activating the digesting agent in the tank, and a device for enabling the activated digesting agent to contact the organic material. The activating device is preferably a heating element. The enabling device is preferably an exit pipe. The invention has particular application in the preventative maintenance of a grease trap drainage system.

Abstract: An apparatus is constructed and arranged for activation of a digesting agent upstream of where it is introduced to contact an organic material. The apparatus includes a container for housing dormant digesting agent communicating with a tank having a temperature controlled heating element for activating the digesting agent and a valved exit pipe coupling the tank to a system containing the organic material to be digested. Timers control movement of the agent from container to tank and then out of the tank. The apparatus is particularly applicable to maintenance of drainage systems such as those handling effluent from restaurant kitchens.
