Effects of magnetic field on activity of activated sludge in wastewater treatment

Hülya Yavuz, +1 more
- 01 Jan 2000 - 
TL;DR: In this paper, the effects of magnetic field on activity of activated sludge in wastewater treatment were investigated in a batch reactor system containing synthetic wastewater, where the medium pH and the direct current (DC) magnetic field strength were changed in the ranges of 6.0 to 8.5 and 8.9 to 46.6 mT, respectively.

Steady-state iterative learning control for a class of nonlinear PDE processes

Deqing Huang, +1 more
- 01 Sep 2011 - 
TL;DR: In this paper, a P-type steady-state iterative learning control (ILC) scheme is applied to the boundary control of a class of nonlinear processes described by partial differential equations (PDEs), which cover many important industrial processes such as heat exchangers, industrial chemical reactors, biochemical reactors, and biofilters.

The digestibility of waste activated sludges.

Chul Park, +2 more
- 01 Jan 2006 - 
TL;DR: The results of the study show that the cation content in wastewater is an important indicator of the material that will digest under anaerobic or aerobic conditions and that some of the volatile solids will digest only under either anaer aerobic or aerobicconditions.

Settling velocities and permeabilities of microbial aggregates.

Xiao-yan Li, +1 more
- 01 Jul 2002 - 
TL;DR: It was demonstrated that the microbial aggregates were highly porous and fractal, however, their settling velocities observed in deionised water, EDTA and NaCl solutions were only slightly faster than predicted by Stokes' law for identical but impermeable particles.

Treatment of mezcal vinasses: A review

Vania Robles-González, +3 more
- 20 Feb 2012 - 
TL;DR: Mexico's mezcal vinasses seems to be a low cost technology very well suited for rural regions in underdeveloped countries where more sophisticated technologies are difficult to adopt, due to high costs and requirements of skilled personnel.
