Domestic sewage vermifilter showing accumulated contents (composting worms exposed) A vermifilter (also vermi-digester or lumbrifilter) is an aerobic treatment system, consisting of a biological reactor containing media that filters organic material from wastewater.
Vermifilter toilet, also known as a primary vermifilter, vermidigester toilet, tiger toilet [1] [2] or tiger worm toilet, [3] is an on-site sanitation system in which human excreta are delivered from a toilet (usually by flushing) onto a medium containing a worm-based ecosystem.
Vermicast (also called worm castings, [a] worm humus, worm poop, worm manure, or worm faeces) is the end-product of the breakdown of organic matter by earthworms. [1] These excreta have been shown to contain reduced levels of contaminants and a higher saturation of nutrients than the organic materials before vermicomposting.
Vermicompost (also called worm castings, worm humus, worm manure, or worm faeces) is the end product of the breakdown of organic matter by earthworms. [60] These castings have been shown to contain reduced levels of contaminants and a higher saturation of nutrients than the organic materials before vermicomposting. [61]
Megascolecidae is a family of earthworms native to Madagascar, Australia, New Zealand, Asia, and North America. [2] At up to 2 meters in length, [3] their large size distinguishes the Megascolecidae from other earthworm families.
They are also often the numerically dominant earthworm species in England, especially in neutral to base-rich grasslands and arable soils. [9] Because Allolobophora chlorotica is an endogeic worm, it builds complex lateral burrow systems through all layers of the upper mineral soil. This species of worm rarely comes to the surface, instead it ...
There are over 22,000 living annelid species, [6] [7] ranging in size from microscopic to the Australian giant Gippsland earthworm and Amynthas mekongianus, which can both grow up to 3 meters (9.8 ft) long [7] [8] [9] to the largest annelid, Microchaetus rappi which can grow up to 6.7 m (22 ft).
Sultan Ahmed Ismail (born 9 October 1951) is an Indian soil biologist and ecologist.His work has centred on techniques for recycling biodegradable waste into fertilizer using local varieties of earthworms, and on soil bioremediation.
