It is estimated that approximately 1.1 billion people globally drink unsafe water. We previously reported both a novel copper-alginate bead, which quickly reduces pathogen loading in waste streams and the incorporation of these beads into a novel swirl flow bioreactor (SFB), of low capital and running costs and of simple construction from commercially available plumbing pipes and fittings. The ...

The ANITATM Mox Process is a single-stage deammonification process utilizing moving bed biofilm reactor (MBBR) technology. Early studies indicated that the Integrated Fixed-Film Activated Sludge (IFAS) configuration was an effective approach to improve ANITATM Mox performance. Two studies on ANITATM Mox IFAS were conducted at full-scale and pilot-scale levels. The full-scale study compared the ...

This study presented the performance of simultaneous nitrification and denitrification (SND) process using a new developed hybrid airlift reactor which integrated the activated sludge reaction process in the airlift reactor and the sludge settling separation process in the clarifier. The proposed reactor was started up successfully after 76 days within which the COD and total nitrogen removal r...

The article analyzes the dynamics of channel processes in irrigation pumping station inlet channels. field studies hydraulic and alluvial sediment regimes supply channels stations are analyzed summarized. water flow under conditions extremely high turbidity variability morphometric characteristics presented. which Saint-Venant equations satisfactorily describe flows bed given. Saint-Venant's tw...

Recent research has indicated the advantages of combining anaerobic and aerobic processes for the treatment of municipal wastewater, especially for warm-climate countries. Although this configuration is seen as an economical alternative, is has not been investigated in sufficient detail on a worldwide basis. This work presents the results of the monitoring of a pilot-scale plant comprising of a...

Floating bead filters (FBFs) are expandable granular filters that display a bioclarification behavior similar to sand filters. They function as a physical filtration device (or clarifier) by removing solids, while simultaneously encouraging the growth of bacteria that remove dissolved wastes from the water through biofiltration processes. Presently, there are two classes of FBFs that exist. Hyd...

The Sanitation Districts of Los Angeles County (Districts) operate 11 wastewater treatment facilities. Ten of these facilities are classified as water reclamation plants (WRPs) producing approximately 200 million gallons per day (MGD) of reclaimed water suitable for reuse. The Districts' Palmdale WRP treats approximately 10 MGD using primary treatment followed by stabilization ponds. This facil...

A Hg-contaminated site in B.C. Province, Canada was caused by the previous operation of Hg-cell in chlor-alkali process for over 25 years. The soils and groundwater at the site are highly contaminated with mercury. An analysis of groundwater at the site has shown that most of the mercury is bonded with humic and fulvic acids (HFA) in colloidal form. The Hg-HFA colloids can be completely removed...

The increasing presence of potentially toxic cyanobacterial blooms in drinking water sources and within drinking water treatment plants (DWTPs) has been reported worldwide. The objectives of this study are to validate the application of in vivo probes for the detection and management of cyanobacteria breakthrough inside DWTPs, and to verify the possibility of treatment adjustment based on inten...
