EFFECT OF DIFFERENT PARAMETERS FOR THE REMOVAL OF FLUORIDE FROM WATER AND WASTEWATER USING INDUSTRIAL SOLID WASTE LIKE CHINACLAY

*Dr. P. P. Vishwakarma

ABSTRACT

Exposure to fluoride beyond the recommended level for longer duration causes both dental and skeletal fluorosis. Thus, the development of cost- effective, locally available, and environmentally benign adsorbents for fluoride removal from contaminated water sources is absolutely required. Presence of fluoride in low concentration (< 1.5 mg L⁻¹) is beneficial to the people for the calcification of dental enamel and maintenance of healthy bones. Fluoride presence in higher concentration become a monster and can cause dental, skeletal fluorosis and also non-skeletal problems. Among several treatment technologies applied for fluoride removal, adsorption process has been explored widely and offers satisfactory results especially with surface modified adsorbents. It is evident from the literature survey that various adsorbents have shown good potential for the removal of fluoride. Batch adsorption experiments were conducted to obtain the optimum conditions for fluoride removal.Effect of parameters like contact time, pH, temperature and adsorbent dose were also determined.
