Fluoride sludge converted into bricks
Excerpt: Prof. (Dr.) Hirani stated CSIR-CMERI also engages in responsible management of Fluoride Sludge by converting it into bricks for construction purposes. This helps in preventing fluoride contamination through sludge from surface run-offs/leaching. *Original article titled CSIR-CMERI Director speaks on “Advancements in Water-RO Purifications & Opportunities of Manufacturing in Rajasthan“, online at http://www.uniindia.com/csir-cmeri-director-speaks-on-advancements-in-water-ro-purifications–opportunities-of-manufacturing-in-rajasthan/east/news/2181845.html Print PDF

Encapsulation of fluoride sludge in stabilised mud blocks
Abstract Non-engineered disposal of hazardous sludge can contaminate surface water and groundwater sources. Defluoridation of water using magnesium oxide (MgO) is being implemented in a village in Karnataka, India. Defluoridation of water by the MgO method produces fluoride-contaminated magnesium oxide sludge (FCMOS). This paper examines the impact of encapsulating FCMOS on the engineering and environmental […]

Low-cost defluoridation of water using broken bricks
Abstract: A low cost domestic defluoridator has been developed by the National Water Supply & Drainage Board of Sri Lanka to remove excess fluoride in drinking water to avoid endemic Fluorosis. Broken pieces of freshly burnt bricks are used as filter media in these units. A kinetic model for fluoride uptake in the filter with […]

Fluoride adsorption by clay minerals and hydrated alumina
Extract In the course of some studies on the effects of anions on the viscosities of clay suspensions, it was observed that anions such as pyro- and metaphosphate, oxalate and fluoride were much more effective in reducing the viscosity of kaolih suspensions than were chloride and nitrate. There is relatively little information available regarding the […]
