    The study aimed to establish the optimum conditions for biological treatment of the leachate from the Glina household waste disposal site. The variation in nitrate, nitrite, phosphate, ammonium and suspended matter content in relation to contact time between microorganisms and leachate was analyzed to highlight the activity of microorganisms at different contact times. Experimental results have shown that the highest efficiency in the removal of nitrates and nitrites corresponds to the contact range of 16-24 hours, while the degradation efficiency is very low for contact time below 8 hours. The higher content of leachate suspensions was recorded over 5 days of contact, after which a continuous decrease was achieved by the end of the experiment. Positive inflection on biological purification by lowering the content of ammoniacal nitrogen, phosphorus, oxygen content and biochemical oxygen content between 16 and 32% after 20 hours of contact time.
