BIOACTIVE POWDER consists of microorganisms selected for their ability to degrade organic wastes, cellulose and lignin in urban waste waters. The aerobic microorganisms in the product degrade the wastes in the septic tanks by means of aerobic oxidation. So, the anaerobic microorganisms in the medium cannot find anything to feed on. By this action, the anaerobic corrosion and foul odors are stopped. Additionally, the microorganisms in BIOACTIVE POWDER break the hardened organic deposits and tartar under the septic tank, so that the liquefied wastes can easily pass to the soil.
