A PROCESS FOR PREPARING ARSENIC FREE (10 ppb) WATER FROM ARSENIC CONTAMINATED GROUND WATER AND AN EQUIPMENT THEREFOR

摘要

A process for preparing arsenic free ( 10 ppb) water from arsenic contaminated ground water, characterised in that mixing arsenic contaminated ground water with an homogeneous suspension in aqueous medium essentially containing fine particles of size below 20 µm of arsenic adsorbing media having concentration in the range of less than 5000 ppm, circulating the resultant mixture under pressure in the range of 0.1 to 3 Kg/cm2 through one or more porous ceramic pressure filtration tubes of pore size in the range 1 to 10 µm of the said arsenic adsorbing media
