The treatment performance and nitrogen mass balance of a pilot-scale landfill leachate system was evaluated. comprised series three ponds rock filter fed continuous flow (200 L d−1) during 111 weeks. Three different operational conditions were investigated: conventional operation (stage I), aeration II) aeration/recirculation III). able to treat with soluble chemical oxygen demand ammonia removal between 35–82% 75–99%, respectively, the highest occurred recirculation stage. calculated using...
The following sludge reduction alternatives were tested in wastewater biological reactors: oxic-settling-anaerobic (OSA-process); ultrasonic disintegration (UD); chlorination (CH); 3,3',4',5-tetrachlorosalicylanilide (TCS); and folic acid (FA). Compared to the control system, UD reduced 55% of production, greater substrate nutrient removal efficiency was achieved. CH worsened settleability increased SVI values; system achieved 25% reduction. OSA showed 50% 60% after 16 10 hours under...
This study treated sanitary landfill leachate and was conducted in a pilot-scale system composed of three serial ponds (P1, P2 P3), followed by rock filter, order to evaluate the microbial consortium influence on performance investigate microorganism dynamics process. The broken into stages, with continuous flow rate (Q = 200 L d−1) for 43 weeks. stages were as follows: conventional operation (stage I), 12 h aeration II), 18 III). results showed possibilities treating leachate, presenting an...
O objetivo deste estudo foi avaliar o desempenho de um sistema tratamento lixiviado aterro sanitário, em escala piloto, formado por três lagoas série (L1, L2 e L3) seguidas filtro pedras (FP). Foram estudadas condições operacionais, verificando-se efeito da recirculação do efluente L3 para a L1: 0, 50 100% vazão. absorveu bem as flutuações cargas, apresentando remoções superiores 80% DBO F, 70% DQO T 98% nitrogênio amoniacal. Na lagoa houve nitrificação parcial, com acúmulo nitritos. Ocorreu...
ABSTRACT: The performance of a pilot stabilization ponds system was evaluated for the treatment sanitary landfill leachate, focusing on effluent detoxification. Three serial (anaerobic—P1, facultative—P2, and maturation—P3) were during two different operational conditions: natural condition (period 1) 24 hours artificial aeration in P2 2). exhibited removal efficiencies 53% soluble chemical oxygen demand (SCOD), 81% filtered biochemical (FBOD), 84% NH 4 + ‐N period 1 70% SCOD, 80% FBOD, 96%...
The aim of this study was to investigate the ability oxic-settling-anaerobic (OSA)-process and folic acid addition applied in activated sludge process reduce excess production. monitored during two distinct periods: system with OSA-process, addition. observed yields (Yobs) were 0.30 0.08 kgTSS kg(-1) chemical oxygen demand (COD), control phase OSA-process (period 1); 0.33 0.18 COD, 2). Yobs decreased by 73 45% phases addition, respectively, compared phases. minimization alternatives result a...
RESUMO Os reatores operados em bateladas sequenciais (RBS) com biomassa granular aeróbia são uma tecnologia compacta e promissora no tratamento de águas residuárias. Porém, sua utilização esgoto sanitário ainda é um desafio, devido à instabilidade desintegração dos agregados. O presente trabalho avaliou a granulação da RBS escala piloto, sem adição inóculo, para o sanitário. estudo foi dividido três estratégias operacionais ciclos compostos pelas fases: enchimento, anóxica, aeróbia,...
