A study on contaminant migration of sugarcane effluent through porous soil medium

Abstract

ABSTRACT:A significantly large volume of effluent is generated during the manufacture of sugar and contains high amount of pollution load. The effluent from sugarcane industry is disposed off on land moves into the wider environment through a number of routes and the soil itself retains the various contaminants in the effluent to a greater or lesser extent depending on the physical nature of the soil. The analysis of contaminant transport through soil used to design of industrial wastewater treatments and disposal systems. This paper discussed the adsorption and diffusion of cations calcium, magnesium, sodium and anions chloride and sulphate by the sorption diffusion permeameter under different hydraulic retentions time of 3 min, 13 min, 27 min and 58 min with a constant diffusion flow rate of 3.6 L/h. In this study, less percentage error found between observed adsorption and diffusion coefficients from the experiments at different hydraulic retentions time and optimum adsorption and diffusion coefficients from the experiments at optimum hydraulic retentions time of 30 min for calcium, magnesium, sodium, choloride and sulphate. The results of regression analysis implied that the adsorption and diffusion coefficients obtained from the equation for cations and anions were good recognizing with the experimental results.

Experimental investigation of groundwater contamination by surface sources: Determination of adsorption capacity, diffusion, and sorption potential of selected anions in different soils

“…After attaining the pseudo‐adsorption equilibrium, less than 2% deviation in amount of chloride or sulfate was noticed even after 24 hr. Similar observations were found in chloride and sulfate migration from sugarcane effluent through clay‐loam soil, indicating a reduction of 24.24% chloride and 17.98% sulfate within 30 min (Sivakumar, ). On the other hand, the time to attain the pseudo‐equilibrium concentration showed an increase with an increase in OM in the soil for both of the anions.…”

Diffusion study of municipal solid waste contaminants in compacted lateritic soil treated with bacillus coagulans

“…Diffusion is a transfer mechanism for fluid flow from area of higher concentration or gradient to lower concentration or gradient. The flow of contaminant in a landfill system most times is based on advective-dispersive transport alongside the fractures or micropores as reported by past investigations (Rowe and Booker, 1989;Fityus et al, 1999;Neretnieks, 2002;Sivakumar, 2011). Also, transport of contaminant may be by diffusive transport from the fractures or micro pores into the adjoining porous soil matrix (Barone et al, 1990;Shackelford, 1991;Liu et al, 2002;Sivakumar, 2011).…”

Monovalent cations (Sodium, Na + and Potassium, K + ) and divalent cations (Calcium, Ca 2+ and Magnesium, Mg 2+ ) were chosen for the evaluation of the adsorption potential of lateritic soil-B.…”
