Wastewater treatment by vermi filtration technologyvivatechijri
Vermifiltration units are sludge-free, noise-free and low- or no-electricity-requiring systems of
operation. The aim of this study was to emphasize wastewater treatment by vermifiltration technology using
waste-eater earthworms to highlight the benefits of clean and nutritive vermifiltered water (vermiaqua) uses in
agriculture to the farmers. They work on natural capacity of earthworms to treat wastewater from different
sources. In view of rising concern about pollution of water bodies due to discharge of waste in them, it is
necessary to initiate alternative thinking as conventional methods through STPs (Sewage treatment Plants) have
had limited success. In recent years the application of specifically designed filtration based technology
(popularly known as Vermifiltration technology) for treatment of wastewater municipal, urban and agricultural,
is becoming widely acceptable. It treats the wastewater in natural manner without the use of chemicals. In
short, Vermifiltration technology is an improved filtration system for treatment of wastewater. The main
objective of present research work is to provide and popularize a simple, feasible, practically sound, ecofriendly and cost effective technology for wastewater treatment. Vermifiltration technology is such a type of
system, which reduces the impact of sewage and converts into useful water for gardening and irrigation
purpose.
The issue of supplying adequate water to meet societal needs is one of the most urgent and significant challenges faced by decision-makers.
Rainwater harvesting is an excellent means of supplementing water for both potable and non-potable purposes.
Rainwater harvesting describes processes in which precipitation that falls on a site is diverted, captured, and stored for use on-site, as opposed to allowing it to run off, evaporate, or infiltrate into the soil.
This PowerPoint contains information about a water system that can be used to recycle grey water; it also explains the terms as like Water Supply, Sanitation, Water Hygiene and Waste Management...

Water treatment is any process that improves the quality of water to make it appropriate for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components, or reduces their concentration so that the water becomes fit for its desired end-use. This treatment is crucial to human health and allows humans to benefit from both drinking and irrigation use.
In this slide we know about aeration method and coagulation process. Which is used in Drinking water Treatment Plant. In Aeration process oxygen got dissolved with natural phenomena and presence of sun ray. By help of this method the minor and major type of bacteria automatically cleaned. this method have different types:- 1) Stepped Aeration 2) Fountain Aeration.
second one is the Coagulation Process. In the water various types of small partials are present which can not be possible to see from naked eyes. So that we use this process and settle down all the partical by adding coagulation agent like alum.
Wastewater treatment is a process used to remove contaminants from wastewater and convert it into an effluent that can be returned to the water cycle. Once returned to the water cycle, the effluent creates an acceptable impact on the environment or is reused for various purposes (called water reclamation).
A sewage pump is located in the bottom of basin. It is a device used to move liquids with solids all over a sewer system. Sewage Pumps designed to drain out wasted liquids and semi-solids that contaminated in the home basements and other secluded areas. Here Pumpkart.com sharing the more information about the sewage pumps and their uses that can helps to increase your knowledge about these.
