ABSTRACT:
A stabilized dust-free powdered enzyme/bacterial fermentation product is provided for readily treating drains, septic tanks, distribution boxes, holding tanks, drain fields, sewer lines, dry wells, grease traps, compost heaps, and garbage disposals. The stabilized powdered formulation effectively digests and liquifies most organic wastes flushed into on-site waste disposal systems. The environmentally attractive product can also be used for regular periodic sludge pumpouts. The waste-digesting composition can include: enzymes, enzyme preservatives, enzyme activators, nonpathogenic aerobic and anaerobic bacteria, bacterial nutrients, buffers, emulsifiers, and heavy metal scavengers. In a preferred embodiment the composition contains multiple enzymes having less than 26% by weight of the total weight of the composition, and specifically 0.1% to 15% protease, 0.1% to 15% amylase, 0.1% to 15% cellulase, 0.1% to 15% lipase, 0.1% to 15% Bacillus species, 0.1% to 20% phosphate-containing buffer compounds, such as monosodium phosphate, 1% to 20% enzyme preservative, and 0.1% to 10% ion scavenger compounds, as well as 50% to 95% dendritic salts also providing a buffering effect for the composition.
