The biological removal of phosphorus from simulated wastewater using miniature bioreactors
The objective of this study was to utilize miniature bioreactors in a laboratory-scale setting to biologically deplete excessive amounts of phosphorus (P). P occurring in wastewater is usually found in the form of phosphate (PO4). The potential for phosphate-removing bacteria (PRB) to overload significant levels of PO4 under aerobic/anaerobic conditions was observed and evaluated. Wastewater was simulated by adding four different PO4 concentrations of 20, 30, 38, and 45 mg-L-1 to deionized water, ... |

Application of chlorine resistant polyamide RO membrane for household water filtration device
Chlorine attacks the polyamide RO membrane to cause membrane failure as measured by enhanced passage of both salt and water. For this reason, activated carbon pre-filters that remove chlorine are typically placed ahead of RO membranes in home drinking water treatment RO system. A general home drinking water treatment system employing RO is composed of preliminary sediment filter, activated carbon pre-filter, a reverse osmosis membrane, and an activated carbon post-filter. In this respect, a chlorine ... |
