Simultaneous Biodegradation of Linear Alkylbenzensulfonate in Anaerobic Reactors, in Two Stages
Surfactants are organic compounds capable of altering the surface or interfacial tension of a system; they alter the hormonal system of aquatic organisms and can penetrate porous materials, disperse solid particles, emulsify oils and fats or produce foam when agitated. They are used in the manufacture of cleaning and personal hygiene products, manufacturing of products with agricultural, industrial and commercial applications. But they are highly polluting due to their special chemical composition, they cause eutrophication problems in natural bodies of water due to the amount discharged and the frequency with which they are discharged, in addition to affecting ecosystems. One of the most used anionic surfactants in the manufacture of commercial detergents due to its excellent detersive properties and low cost, is LAS. The objective of this research was to evaluate the effect of the concentration and organic loading rate of the anionic surfactant “LAS” on the performance of a two-stage anaerobic reactors system for its simultaneous biodegradation. The results showed that both at concentrations of 200 mg/L (experiment V) and 300 mg/L of “LAS” (experiment VI), the acidogenic reactor showed greater robustness in the biodegradation (86.7 and 55%) at an organic loading rate of 5.92 ± 0.04 and 6.8 ± 0.09 kgCOD/m3.d; the methanogenic reactor was more sensitive to the presence of the surfactant (experiments V and VI), biodegrading it by 13.8 and 14.3% with respect to the LAS remaining in the effluent of the acidogenic reactor with which it was fed, to 3.56 ± 0.02 and 4.48 ± 0.15 kgCOD/m3.d respectively.
期刊介绍:
Water, Air, & Soil Pollution is an international, interdisciplinary journal on all aspects of pollution and solutions to pollution in the biosphere. This includes chemical, physical and biological processes affecting flora, fauna, water, air and soil in relation to environmental pollution. Because of its scope, the subject areas are diverse and include all aspects of pollution sources, transport, deposition, accumulation, acid precipitation, atmospheric pollution, metals, aquatic pollution including marine pollution and ground water, waste water, pesticides, soil pollution, sewage, sediment pollution, forestry pollution, effects of pollutants on humans, vegetation, fish, aquatic species, micro-organisms, and animals, environmental and molecular toxicology applied to pollution research, biosensors, global and climate change, ecological implications of pollution and pollution models. Water, Air, & Soil Pollution also publishes manuscripts on novel methods used in the study of environmental pollutants, environmental toxicology, environmental biology, novel environmental engineering related to pollution, biodiversity as influenced by pollution, novel environmental biotechnology as applied to pollution (e.g. bioremediation), environmental modelling and biorestoration of polluted environments.
Articles should not be submitted that are of local interest only and do not advance international knowledge in environmental pollution and solutions to pollution. Articles that simply replicate known knowledge or techniques while researching a local pollution problem will normally be rejected without review. Submitted articles must have up-to-date references, employ the correct experimental replication and statistical analysis, where needed and contain a significant contribution to new knowledge. The publishing and editorial team sincerely appreciate your cooperation.
Water, Air, & Soil Pollution publishes research papers; review articles; mini-reviews; and book reviews.
