Sažetak
The efficiency of electrocoagulation augmented with natural zeolite is tested on two leachate samples obtained from composting of biowaste. Electrocoagulation is conducted with aluminum electrode in duration of 60 min, at current intensity and applied voltage of I = 0.1 A, U = 29.9 V, respectively. Results show that addition of zeolite (at solid/liquid ratio of 20 g/L) influencing on neutralizing the final pH values in leachate solutions, while decreasing the el. conductivity (>34 %), turbidity (>99%), COD (>84 %) and total Kjeldahl nitrogen (>81%). Moreover, zeolite particles acted abrasively on the electrode and contributed to cleaning the electrode surface from oxides, corrosion products and organic mucous layer formed on anode by complexing aluminum with organic compounds in leachate. Beside aluminum dissolution from the anode, aluminum dissolution from the cathode is also recorded, confirming that both electrodes are influencing on forming floc of Al(OH)3 during electrocoagulation. In addition, the overall operational costs of were evaluated and discussed. Results indicate that electrocoagulation augmented with zeolite can be considered as a cost-effective process for treatment of leachate from composting of biowaste.
