This paper is of some historical interest. It describes an investigation to determine whether byssinosis occurred among workers in the waste cotton industry. It was undertaken in 1950 at the instigation of the Minister of National Insurance. The materials used in the industry were (i) cotton that had been previously spun, and (2) waste material discarded during the preparations for spinning hig...

As available at lowor zero-cost, agricultural and food industry waste biomass has great potential to be used for wastewater treatment. It been shown that, with minimum of chemical or mechanical pre-treatment, adsorption capacity different heavy metals, organic biological pollutants from both drinking wastewater. Since is a renewable resource that generated daily as requires storage, its inclusi...

Because of the breadth of the subject, the problems concerning the treatment of waste water are limited to those of (i) the production of organic chemicals which are produced on a petrochemical basis in chemical plants, (ii) the production of various derivatives selected according to their importance and (iii) the production of some of the more important vinyl polymers. Specific quantities of w...

Korea's urban environmental problems, specifically air and water pollution, government environmental policies, and the role of nongovernmental organizations (NGOs) in protecting the environment are described and discussed. Korea's rapid industrialization and urbanization between 1961 and 1985 led to an increased volume of waste and air pollution. Automobiles increased in number from 29,234 in...

conclusions based on nitrification and denitrification data, the best condition for nitrifying/ denitrifying performance was obtained by modified-ifas. hence, the modification can be used to obtain the best activities of microbial and nitrogen removal improvement. results employing the bet, surface area (sa), total pore volume (vp), and average size of the nanostructure were 0.4026 m2/g, 3.8089...

In recent years, semiconductor photocatalytic process has shown a great potential as a low-cost, environmental friendly and sustainable treatment technology to align with the "zero" waste scheme in the water/wastewater industry. The ability of this advanced oxidation technology has been widely demonstrated to remove persistent organic compounds and microorganisms in water. At present, the main ...

Emami Paper Mill Ltd. at Balgopalpur industrial area produces a huge amount of fly ash and waste water to the environment. The application of disposed fly ash and waste water in crop cultivation may reduce the problem to some extent. The aim of this study is to investigate the effects of direct land application of fly ash on plant growth and production of rice (Oriza sativa). In the fly ash exp...

The waste water showed high values of total solid (TS), hardness and chloride with slightly alkaline pH along with high concentrations of Cr (2.03 mg l(-1)), Ni (1.59 mg l(-1)) and Zn (0.46 mg l(-1)). The concentration of Cu (0.21 mg l(-1)) and Zn in industrial waste water was low than Ni and Cr. The diluted (25 and 50%), undiluted (100%) waste water was used to irrigate the lettuce plants grow...
