Abstract
In recent years, stringent discharge standards prior to the release of effluent into the water bodies have led to implementation of diverse advanced biological treatment processes in various industries. Biological treatment is a fundamental part of industrial wastewater treatment, contains soluble inorganic/organic pollutants. Being a cost-effective process, biological treatment has an economic advantage over chemical and physical processes. It employs a range of microorganisms which as a community form a microbial biofilm. Microbial biofilm provides a diverse range of micro-niches to microbial communities and protection from physical agitation to support metabolic potential and functional stability. Currently, biofilms are applied in wastewater treatment, degradation of toxic waste in water and soil and production of various commercial products. Intensive exploration has proved the importance of biofilm as a highly promising biotechnology, especially in wastewater treatment.
