Biological treatment of industrial wastewater: an effective, environmentally-friendly solution<\/h2>\n\n

Aerobic treatment<\/h3>\n\n

First and foremost are aerobic treatments for industrial wastewater.\nThese systems are based on the addition of air (oxygen) to the effluent reactor to be treated.\nThis process is effective in reducing organic loads (BOD and COD) as well as nitrogenous loads, down to very low levels.\nAerobic reactors can be combined with anaerobic or anoxic (low-oxygen) reactors to optimize operating conditions or take treatment further.\nAerobic treatments are highly efficient and resilient in their operation. <\/p>\n\n

Different aerobic treatment technologies can be implemented depending on the effluent and project conditions:<\/p>\n\n

    \n
  • Activated sludge system<\/li>\n\n\n\n
  • Membrane bioreactor (MBR)<\/li>\n\n\n\n
  • Moving bed biofilm reactor (MBBR)<\/li>\n\n\n\n
  • Sequenced Bioreactor (SBR)<\/li>\n<\/ul>\n\n

    Anaerobic treatments<\/h3>\n\n

    Then there are the anaerobic processes, which evolve in the absence of oxygen.\nThe bacteria used in this process are highly efficient, particularly for treating effluent with a high concentration of biodegradable organic matter.\nDuring the anaerobic digestion process, the bacteria generate biogas that can be collected and valorized in an engine or boiler. <\/p>\n\n

    Advanced technologies and environmental benefits<\/h2>\n\n

    Membrane bioreactor (MBR)<\/h3>\n\n

    One type of process that is particularly well-suited to the needs of industry is the membrane bioreactor (MBR), a state-of-the-art technology that combines activated sludge biodegradation processes with ultrafiltration membrane filtration.\nMembrane filtration considerably increases the concentration of bacteria in the biological stage, thus limiting reaction volumes and the plant footprint.\nThis process stands out for its biodegradation performance and low production of biological sludge. <\/p>\n\n

    Effectiveness of biological treatments<\/h3>\n\n

    One of the main advantages of biological treatment of industrial wastewater is its efficiency.\nBy taking advantage of the activity of micro-organisms to promote the degradation of organic pollutants, BRMs can eliminate up to 95% of the organic and nitrogenous pollution present in industrial effluents. <\/p>\n\n

    Depending on the characteristics of the effluent and the discharge standards to be met, a wide variety of finishing treatments can be added:<\/p>\n\n
