Waste Water Treatment by Aerobic Biofilm

Swine waste treatment by self-heating aerobic thermophilic bioreactors.

Pig manure represents a very high-strength wastewater that is well suited for a self-heating aerobic thermophilic treatment. Here we report the use of 59-L Aerobic Thermophilic Sequencing Batch Reactors (AT-SBR) to study the treatment of pig manure with a HRT of 6 days. Temperatures up to 75 degrees C were reached without external heating by using Venturi-type aerators but these conditions were...

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

Performance of a Three- Stage Aerobic Rbc Reactor in Dairy Waste Water Treatment

Biological treatment using attached growth in a threestage labscale rotating biological contactor (RBC) was implemented for wastewater from dairy industries. The wastewater contained high level of organic compounds due to cleaning and filling processes. Nutrients available in the wastewater enhanced the growth of microorganisms and allowed the biological treatment to be effective. The RBC consi...

Waste Water Treatment by Inverse Fluidization Process: an Overview

The present study attempts to summarize the salient characteristics of hydrodynamics behavior of inverse fluidized system, effect of particles properties, various phenomena that affect the fluidization like bubble formation, fluid velocity and its various uses in commercial scale by reviewing the previous literature. Governing mechanisms of inverse fluidization system and some heat and mass cor...
