This Manual is needed for the technical persons to be trained as Operators and helpers at the FSTP site at Thrissur. It contains Technical Guidelines for carrying out the works.
Vermifiltration is a more efficient method of sanitation relative to septic tanks and pit latrines. Earthworms are well known agents that promote digestion of organic waste, producing vermicompost.
The Tiger Biofilter technique is based on vermifiltration. The technology uses a filtration arrangement consisting of Bio media to trap and treat impurities from faecal sludge / wastewater. The filtration medium is arranged in stacked manner with bio media (consist vermicompost, cocopeat and bacterial culture with worms) on top. The top layer serves as active zone habitat for Bacteria and earth worms specifically bred for the purpose, while bottom layers provides structural support and free drainage for clear water.
The system is designed with sufficient surface area and worm quantity. The worm consumes the BOD (Organic matter) load in 24 to 72 Hrs. making bed available for next loading. As the Natural oxygen transfer takes place no need of artificial air supply in form of blower resulting in less consumption of power and consumables and is therefore cost effective and environmentally friendly.
