River Flooding on Taipei City Area Inundation
Owing to geographic location of Taiwan being on subtropical monsoon zone, so typhoons and storms occur frequently. Typhoons and storms during summer and fall always cause several flooding, flood damages, and human lives loss in Taiwan. The major factors that cause flooding, landslide, and debris-flow in Taiwan are typhoons and storms of monsoon rain season. …
Effects of Turbulence Models on Microbubble Distributions in Dissolved Air Flotation Process for Water Treatment
Dissolved air flotation(DAF) system is one of the water treatment processes that clarifies wastewaters by floating internal contaminants to the water surface by attaching microbubbles to them. Since the first use of DAF for drinking water treatment in Scandinavia during the 1920s, DAF has been very widely used in treating the industrial wastewater effluents such …
Solar Photocatalytic Degradation of 4-Chlorophenol in Water with Novel Shell-Core P3HT@TiO2 Nanoparticles
Shell-core poly 3-hexylthiophene (P3HT)@TiO2 nanoparticles were synthesized by a physical deposition method using tetrahydrofuran (THF) as a solvent of P3HT in a P-25 TiO2/THF suspension. The P3HT@TiO2 nanoparticles were characterized by Scanning Electron Microscope (SEM), X-ray Energy Dispersive Spectrometer (EDS), X-ray diffraction (XRD), UV/VIS Diffuse Reflectance Spectroscopy (UV/VIS DRS), and Fourier Transform Infrared Spectroscopy (FTIR). …
Coastal Urbanization Impacts on Biodiversity the Case of Marinas in Singapore
Marinas are typically designed as a semi-enclosed environment with a complex mix of structures that provide ecological niches throughout the water body. Water flow is inevitably reduced with a possible decline of water quality. This investigation was conducted to determine how marinas affect marine biodiversity. The three marinas studied – Marina at Keppel Bay (MKB), …
Awareness on Fish Depletion and Fishing Practices among Fishermen around River Rima and Kware Lake, Northwestern Nigeria
Human dependence on freshwater fish is significant, owing to the nutritional value provided by fish to populations particularly in the developing world. Fish are overexploited or severely depleted as a result of excessive fishing quotas, illegal fishing practices and poor management of our freshwater resources. Fishermen around River Rima and Kware Lake were surveyed to …
Aerobic Wastewater Treatment Packages: An Environmental and Energy-Saving Option
The water management systems throughout the world employ and depend heavily on water supply management approach to cater the demand. This approach is unsustainable in the long run as water demand will eventually overtake water supply. It requires an effective approach like building water retaining structures; dams, canals etc., along with an effective management plan …
