A Swachhta Status Report released in 2016 by the National Sample Survey (NSS) states that over half of rural and semi-urban India chooses to defecate in the open. In a country where sanitation underlines health. education and life, these numbers area serious concern.

Poor sanitation is not only a sign of poverty, but is also one of the key reasons for it. Lack of proper sewage treatment leads to contaminated water and soil which further contaminates the food chain. Eventually, it creates a rippling effect of ill health which impacts productivity and the economy of our nation.

In the past, conventional solutions such as Dry Pit and Twin Pit Toilets, Septic Tanks, Soak Pits and Eco-San Toilets have proven to be inefficient, heavy on the pocket and have caused more damage to the environment than good. In fact none of these solutions actually treat the human waste. Instead, they act as storage reservoirs for disposal are later stage or rely on Mother Earth to absorb the effluents, thus leading to more contamination. To battle the challenge, Defence Research & Development Organisation (5050), Ministry of Defence. Government of India, spent decades researching coo-friendly waste management techniques. They developed and deployed the Anaerobic Bio-digestion Technology for sewage treatment in toilets at Siachen Glacier for our defense personnel. After a successful run of more than 8 years. the Elio-Digester technology is now being used widely across the country. 

Bio-Digester Technology:

Psychrotrophic bacteria have the natural capability to survive on waste. Anaerobic Bio-digestion Technology uses these bacteria to break down the waste matter into usable water and gas through an anaerobic process. The zero-waste process is not limited by place or temperature (it works from 5°C to 50 °C), and does not need sewerage networks or sewage treatment plants (SIPS). It is an on-site, independent system and does not require any major infrastructure.

The revolutionary on-sltetechnology consists of two parts:

The bacterial formulation known as Anaerobic Microbial Inoculurn (AMI or DRDO BacMria) A specially designed tank called the Bio-Digester Tank (BDT)

The BDT is connected Jo the outlet of the toilet and can be installed either above or below the ground. The sewage matter flows into the BDT from the toilet and the AMI treats it (digests it) into an effluent that is safe to discharge The human waste matter is broken down into water, carbon dioxide and methane (biogas). 

Bio-Digester Tanks:

To change the sanitation scenario in India over the long-terrn, a systemic value-chain approach is needed. With this vision in mind, K. K. Nag has joined hands with DIRDO to introduce sustainable measures such as the maintenance-free 310-Digester Tank. These can be installed across environments. are customizable and cost-effective. They even use less water, which further strengthens their eco-friendly features and encourages adoption on a wide scale. 

Features of Bio-digestion tanks: 

• Rotationally moulded, factory assembled, ready for installation 
• Material of construction: Polyethylene  
• Tank wall thickness: 7mm (minimum) 
• Heavy-duty poly-grass matting to ensure good formation of bacterial colonies 
• 3 compartment design for complete digestion of faecal matter 
• Lifting hooks for ease of handling 
• Inbuilt vent pipe
