“…Overall N, P and Fe removals obtained in this system were above 70% for diluted leachate. Orupold et al [36] studied the feasibility of lagooning to treat phenolic compounds as well as organic matter. Abatement of 55-64% of COD and 80-88% of phenol was achieved.…”

Problem Statement: Sanitary landfilling is the most common way to eliminate solid urban wastes. An important problem associated to landfills is the production of leachates. This study is a review of landfill leachate treatments. Approach: The advantages and disadvantages of the various existing leachate treatments discussed under the items: (i) Leachate channeling (combined treatment with domestic sewage, recycling) (ii) Biological processing (aerobic and anaerobic) (iii) Chemical/physical treatment (flotation, coagulation/flocculation, chemical precipitation, adsorption, ammonium stripping, chemical oxidation, ion exchange and electrochemical treatment) (iv) Membrane filtration (microfiltration, ultrafiltration, nanofiltration and reverse osmosis). Conclusion: The major fraction of old or biologically treated leachate was large recalcitrant organic molecules that are not easy removed during biological treatment. So that, in order to meet strict quality standards for direct discharge of leachate into the surface water, a development of integrated methods of treatment, a combination of biological, chemical, physical and membrane process steps, were required. Today, the use of membrane technologies, more especially Reverse Osmosis (RO), either as a main step in a landfill leachate treatment chain or as single post-treatment step had shown to be an indispensable means of achieving purification.

“…The p-substituted phenols are more readily degradable than the m-or the o-substituted ones. It has been also reported in the literature that resorcinols are potentially more slowly degradable than monohydric phenols [21,22].…”

The aim of this study was to investigate aerobic biodegradability of phenol, resorcinol and 5-methylresorcinol and their different two-component mixtures using activated sludge sampled from the Kohtla-Järve wastewater treatment plant. The degradation behaviour of phenolic compounds was investigated by respirometry. Non-linear regression analysis was used for determination of the kinetic parameters such as the maximum rate of oxygen uptake (max , O 2 V), the maximum rate of substrate bio-oxidation (V max) and the half-saturation coefficient (K S). Various kinetic models were tested to obtain the best curve fit. It was shown that the activated sludge degraded resorcinol and 5-methylresorcinol more slowly than phenol. Among the studied substrates phenol had the highest values of max , O 2 V , V max as well as the ratio of max , O 2 V /K S. Activated sludge had the highest affinity to phenol with the lowest K S value. Among all studied bi-substrate systems the highest max , O 2 V values were found for phenol (0.1 mM)-5-methylresorcinol. As the kinetic parameters and short-term oxygen demands are functions of the compound undergoing biodegradation and the composition of the microbial community performing the degradation, therefore the results of this study have importance in explanation of effectiveness of wastewater treatment process and of the influence of polluting compounds on it.
