ABSTRACT:
Tablets are formed that release components over time for biological degradation of organic matter such as sewage sludge, petroleum hydrocarbons, pesticides and herbicides. The tablets contain an inner-core of a dormant live microorganism, an inner-coating over the inner-core of water soluble hydroxypropyl methylcellulose or polyethylene glycol, an outer-layer over the inner-coating of sodium sulfate coated sodium carbonate peroxyhydrate particles, and an outer-coating over the outer-layer of water soluble hydroxypropyl methylcellulose or polyethylene glycol. The inner-core may contain a binder such as paraffin, gelatin and dextrose, and the outer-layer may contain additives such as enzymes, buffering agents, sugars and manganese dioxide as an oxidation catalyst. When the tablets are placed in an aqueous environment, layers of the tablets dissolve over time releasing components therein.
