HEAVY METAL REMOVAL FROM LEACHATES AND A GROUNDWATER BY ADSORPTION/CO-PRECIPITATION ONTO METAL-OXIDES-COATED SAND IN A FLUIDIZED REACTOR
This paper introduces principle and advantages of the MetClean™ process and presents pilot testing results for heavy metal removal at two leachate sites and a groundwater site. The process utilizes a fluidized reactor in which active adsorptive metal-oxide coatings are generated in-situ and continuously. The objectives of these pilot studies were to demonstrate that the process was capable of removing dissolved heavy metals, both anions and cations. The effluent concentrations obtained by the process are at least comparable to those from traditional precipitation processes. The experimental results clearly show the effects on the process performance of the following factors: chemical dosage, reactor configuration, degree of fluidisation, and competition among different ions. The residual products from the process are about 90% dry and very stable, and can easily pass the USEPA's TCLP Test.
