Bioremediation-Waste Water Treatment

Bioremediation of Sewage Waste Water using Rhodobacter Capsulatus

Rhodobacter capsulatus is a species of purple bacteria, a group of bacteria that can obtain energy through photosynthesis. It has diverse metabolism and therefore it can be used as a potent bioremedial agent. An attempt was therefore made to evaluate its effectiveness in improving the physico-chemical quality of water contaminated with sewage waste. Certain parameters for the assessment of qual...

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

Bioremediation of reject water from anaerobically digested waste water sludge with macroalgae (Ulva lactuca, Chlorophyta).

Phosphorus and biologically active nitrogen are valuable nutrient resources. Bioremediation with macroalgae is a potential means for recovering nutrients from waste streams. In this study, reject water from anaerobically digested sewage sludge was successfully tested as nutrient source for cultivation of the green macroalgae Ulva lactuca. Maximal growth rates of 54.57±2.16% FW d(-1) were achiev...

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...
