What is a Bio Toilet ? how does a BioToilet Work ?

BioToilet

BioToilet is an assemble unit of  toilet super structure with Bio-Digester Process Unit for complete decomposition of human sewage waste into gases and digested nutrient rich liquid fertilizer residual. Bio Toilet Mechanism is followed by Anaerobic and Aerobic Operation.

Bio Toilet Technology followed by Anaerobic Bio-Digestion Process are more popular than Bio Toilet Technology followed by Aerobic Bio-Digestion Process due to  zero consumption of power and zero discharge of  sludge. 

Bio Toilet Technology Followed By Anaerobic Bio-Digester Process Unit.

Bio Toilet Technology followed by anaerobic biodgester process contain different groups of bacteria. These groups work in sequence, with the products of one  group serving as substrates of another group. Therefore, each group is linked to other groups in chainlike fashion, with the weakest links being acetate production and methane production.

STAGE 1- Hydrolysis Stage 

In Anaerobic Digester Unit, Insoluble solid sewage waste undergo  hydrolysis. human sewage waste consist of  Carbohydrates, Proteins and Fats. These waste are polymeric substances, that is large insoluble molecules consisting of many small molecules joined together by unique chemical bonds.  The Small molecules are solubles are quickly go into solution once the chemical bonds are broken. Hydrolytic bacteria or facultative anaerobes and anaerobes that are capable of performing hydrolysis achieve  breakage of  these unique bonds. Hydrolysis is the splitting of a compound with water. 

 

STAGE II - Acid -Forming Stage

In the acid forming stage, soluble compunds produced through hydrolysis or discharged to the digester are degraded by a large diversity of facultative anaerobes and anaerobes through many fermentative process. The degradation of these compound results in the production of carbon dioxide, hydrogen gas , alcoholes, organic acids, some organic nitrogen compound  and some organic sulfur compound. 

Acetate is the principal organic acid or volatile acid used as a substrate by methane forming bacteria. Carbon dioxide and hydrogen can be converted directly to acetate or methane. the presence of organic nitrogen compound and organic sulphur compound is due to the degradation of amino acids and proteins. The conversion of large soluble organic compunds to small soulable organic compounds results in little change in the organic strength of compounds. some of the organic compounds are converted to organic acid and alcoholes and some are converted to new bacterial cells. it is only in methane formation or the methanogenic stage that degradable organics are removed as methane and carbon dioxide.

STAGE III - Methanogenesis Stage

In the methanogenesis stage, methane is formed mostly from acetate and carbon dioxide and hydrogen gas. All other fermentative product must be converted to compound that can be used directly or indirectly by methane forming bacteria.

Application of BioToilet Treated Sewage Water

BioToilet Treated Sewage Water is utilize for irrigation propose and nutrient rich liquid fertilize composition.

Advantages of BioToilet in Sanitation Sector

• Maintenance free technology
• Zero discharge of sludge
• Self re-generation of Anaerobic bacterial by poymers.
• Reduce maintenance issue of drainage soaking.
• Free from septic tank construction work.
• will help to recharge the ground water level up through utilization of water for gardening and irrigation.
