Abstract: In densely populated coastal cities in Asia, wastewater outfalls are often located not far from sensitive areas such as beaches or shellfisheries. The impact and risk assessment of effluent discharges poses particular ...

Abstract: A mixed segment slack tide oxygen balance model is used to compute BOD/DO concentrations in a heavily polluted tidal estuary. The usual Streeter-Phelps assumptions are adopted for aerobic conditions, while the rate of ...

Abstract: A concentrated 10% chlorine solution (in sodium hypochlorite) with a specific gravity of 1.2 is used for the disinfection of treated primary effluent in the Stonecutters Island Sewage Treatment Works (SCISTW) in Hong Kong. ...

Abstract: In the Hong Kong Harbour Area Treatment Scheme (HATS), a concentrated 10% chlorine solution (in sodium hypochlorite with a specific gravity of 1.2) is used directly to disinfect sewage that receives a chemically enhanced ...

Abstract: Multiport diffusers are used in many environmental applications to distribute a discharge flow uniformly through a number of jet nozzles into the same or another fluid. For example, a sewage diffuser can be designed to ...

Abstract: The Tai Hang Tung Storage Scheme (THTSS) is an essential part of the West Kowloon Drainage Improvement Project that aims to solve the flooding problem in Mongkok, a congested and densely populated district of the Hong Kong ...

Abstract: This study presents an experimental and numerical study for an inclined (60° to horizontal) dense jet discharged into a coflowing current. The mixing and transport of the density current arising from the jet impingement ...
