SOLAR ENERGY UTILIZATION IN INDUSTRIAL EFFLUENT TREATMENT
Department of Chemical Engineering, Nirma University, India
ABSTRACT
Solar energy is a vital source for the treatment of hazardous wastes which are eliminated by the industries. There are equipments like parabolic trough collectors (PTR), flat plate collectors, etc. Used for concentrating the solar energy. Various catalysts such as TiO2 are used for the treatment of waste water by the process called photo catalysis i.e. such catalyst gets activated in the presence of sunlight. Other process like Fenton oxidation, Fenton degradation, and other photochemical methods are useful for the treatment of industrial effluents. Fenton process is well known in all the industries like chemical, pharmaceutical, textile, food, sugar industry for the waste water treatment. Solar drying is an important process for solid waste treatment in which exposure to sunlight can kill various harmful bacterias and other pesticides. Such process is widespread in agriculture sector, cement industry and also food industry. In this paper, we have discussed about the processes which can be helpful to treat industrial wastes by using solar energy.
