Adsorption of wastewater components by natural sorbents

Sorptive properties of the natural zeolite from the Sokyrnytsia Deposit have been investigated with respect to the pollution components of wastewaters from meat-processing plants, namely, ammonium nitrogen, phosphates, and protein, the concentrations of which are subject to standards. Equilibrium values of the adsorption capacity were determined and appropriate sorption isotherms were built for temperature 20A degrees C. It was shown that the adsorption capacity of clinoptilolite with respect to one-component systems was higher as compared with the case of simultaneous adsorption of two and three components from the solution. The linear relationships of the adsorption isotherms for one-, two-, and three-component systems have been also proposed.
