About STP 24

STP 24 contains a synergistic blend of highly advanced and selectively adopted microorganisms, which are naturally occurring, non-genetically engineered; which have been subjected to stringent antibiotic screening; which are designed to provide accelerated degradation of difficult to digest fats, oils, protein, starch, carbohydrates, uric acid, detergents, hydrocarbons, phenols; cotton, plastics, hair, tissue, filters etc. 
It also contain the nutrients required by these microbes which are not available in the septic tank waste.

The Mineral solubilising Microbes present in STP-24 degrade the Minerals present in the Septic Waste. 
Thiobacillus microbes in STP-24 oxidize the H2S gas.
Some Lactobaillus combat E coli and Salmonella.
Nitrosomonas converts Ammonia to Nitrites.
Nitrobacter converts Nitrite into nitrate
Obligates autotrophs solubilize Phosphorous.


It also Contains Activated Carbon, Activated Hydrated Sodium Aluminium Silicate, Activated Aluminum Sulfate, EDTA, Humic Substance, Herbs like Yucca, Methi, Potassium Mono Persulfate, Enzymes like Protease and Lipase. 

Activated Carbon adsorbs obnoxious gases. It also binds virus. It helps in removing halogens such as ozone, chlorine and bromine; and in removing color and metabolic by-products. It adsorbs Chlorine and some chloramine, many dissolved organic contaminants, trihalomethanes (THM), and phenolics, total organic carbon (TOC), oil and hydrocarbon contamination, ozone, bromic acid and total organic halogens (TOX), adsorbable organic halogens (AOX) including chloroform, biological oxygen demand (BOD), chemical oxygen demand (COD), colors, pesticides, odors and more.
Activated Hydrated Sodium Aluminium Silicate also adsorbs poisonous gases. It improves CEC. 
Activated Aluminum Sulfate helps in coagulating all the suspended solids. It lowers the pH.
EDTA is a bleach precursor. It binds Heavy Metals. 
Humic Substances have the ability to influence in particular the metabolism of proteins and carbonhydrates of microbes by catalytic means. This leads to a direct devastating effect against bacteria cells or virus particles. A second mechanism is related to the inter-ionic bonds of high-molecular protein fractions (toxins) of infectious microbes. Their toxic impact on physiological processes of mucous membrane cells can be weakened considerably or even blocked completely.
Yucca and Methi adsorb harmful gases.
Potassium monopersulfate compound is an important auxiliary agent in organic synthesis for oxidizing plenty of organics and functioning - as the epoxy oxidizer of the twin bonds of organic chemicals. It i’s also a free radical introductory agent in many polymeric reactions. Potassium monopersulfate can be used to oxidize hydrogen sulfide (H2S) and other reduced sulfur compounds, such as mercaptans, sulfides, disulfides, and sulfites in waste water treatment
Enzymes like Protease and Lipase help in degrading the Proteins and greases.
