Abstract

Provision of an adequate supply of safe drinking water is a basic necessity for the wellbeing and socio-economic development. In the present invention groundwater contaminated with iron is manually pumped to the aeration chamber of the iron removal plant using water sprinkler through distribution plate and through force & lift arrangement. Holes are provided around the aeration chambers to facilitate maximum flow of ambient air for aerial oxidation. The user can instantly get iron-free potable clear water. Drain pipe, inlet pipe for back wash and back wash line at the bottom of the pre-settling chamber are provided for backwashing purpose.
