Removal of heavy metals from waste water using different biosorbents
The discharge of waste water containing heavy metals like Cr, Cd, Cu from tanneries, electroplating units, metal processing industry etc is the major cause for metal pollution which in turn causes adverse effects in the environment. The conventional methods available for removal of heavy metal are costly and also produce some toxic sludge. This has lead to the invention of new technology like b...
متن کاملRemoval of trace metal contaminants from potable water by electrocoagulation
This study investigated the effects of four operational and environmental variables on the removal of trace metal contaminants from drinking water by electrocoagulation (EC). Removal efficiencies for five metals (arsenic, cadmium, chromium, lead and nickel) were compared under varying combinations of electrode material, post-treatment, water composition and pH. Iron electrodes out-performed alu...
متن کاملArsenic removal from water/wastewater using adsorbents--A critical review.
Arsenic's history in science, medicine and technology has been overshadowed by its notoriety as a poison in homicides. Arsenic is viewed as being synonymous with toxicity. Dangerous arsenic concentrations in natural waters is now a worldwide problem and often referred to as a 20th-21st century calamity. High arsenic concentrations have been reported recently from the USA, China, Chile, Banglade...
متن کاملA Comparative Study of Two Indigenous Bacterial Biosorbents for Mercury Removal from Aqueous Solutions
In the present study, the capability of dried indigenous biomass of Vibrio and Oceanimonas, was assessed and compared for mercury biosorption from aqueous solutions. It was found that both of the biosorbents reached equilibrium after 60 min of contact although the mercury sorption capacity of Vibrio was significantly more. Its sorption capacity increased from 9 to 83 ...
متن کاملReview of fluoride removal from drinking water.
Fluoride in drinking water has a profound effect on teeth and bones. Up to a small level (1-1.5mg/L) this strengthens the enamel. Concentrations in the range of 1.5-4 mg/L result in dental fluorosis whereas with prolonged exposure at still higher fluoride concentrations (4-10mg/L) dental fluorosis progresses to skeletal fluorosis. High fluoride concentrations in groundwater, up to more than 30 ...
