Studies on Colliery Waste Water Treatment

Influence of Thermally Polluted Water on the Growth of Helophytes in the Vicinity of a Colliery Waste Tip

The impact of thermal pollution of leachate from a post-coal mine heap on three macrophyte species: Phragmites australis, Typha latifolia, and Scirpus sylvaticus was examined over the entire vegetation season. Hydrological measurements showed that the temperature of the leachate was ca 50 °C at the site of leachate inflow and decreased to ca 15 °C at the end of discharge canal. The annual tempe...

Treatment of Textile Waste Water with Organoclay

In this study a sample of bentonite obtained from Semnan mines, was modified by a surfactant to prepare an organoclay with high surface area. BET analysis showed that the modification increased its surface significantly. The prepared sorbent was used for removal of dyes and other organic pollutants from a waste water obtained from Ekbatan textile company. Adsorption was studied in ...

Waste Water Treatment using MBR

Algal Bioassay Studies in Waste Water

In order to assessing whether algae can reduce the pollution concentration of the effluents by absorbing the nutrients, it is found that effluents can effectively be treated by employing algal organisisms such as Oscillatoria and Stigeoclonium species and these organisms are frequently found in the polluted waters and they were recorded as pollution tolerant forms. In the laboratory procedures ...

Waste Stabilization Ponds for Waste Water Treatment, Anaerobic Pond

Waste stabilization ponds (WSP) have been used world-wide over the last 50 years for municipal and industrial wastewater. The waste water treatment system has been accepted and used to change the physical, chemical, or biological character of the waste. This article presents the characteristics, parameters, and examples of the waste stabilization ponds all over the world. This work was based on...
