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 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...

Application of Nanoparticles in Waste Water Treatment

In the area of water purification, nanotechnology offers the possibility of an efficient removal of pollutants and germs. Today nanoparticles, nanomembrane and nanopowder used for detection and removal of chemical and biological substances include metals (e.g. Cadmium, copper, lead, mercury, nickel, zinc), nutrients (e.g. Phosphate, ammonia, nitrate and nitrite), cyanide, organics, algae (e.g. ...

Textile Waste Water Treatment With Membrane Bioreactor

Textile waste water treatment for industrial reuse remains as a complicated problem due to several reasons. Among them are: 1) Higher levels of Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) and Total Dissolved Solids (TDS) content of the waste water; 2) Non-biodegradable nature of organic dye stuffs present in the effluent. Thus, any adopted treatment system, especially with resp...
