This paper presents a review of the current state of the art of real time control (RTC) of urban water systems with emphasis on wastewater and urban drainage issues. The paper provides concise definitions of terms frequently used in the literature. Control options for the transport and treatment systems are discussed. Recent developments of the integration of the complete urban wastewater and d...

As the most important resource for life, water has been a central issue on international agenda several decades. Yet, world’s supply of clean freshwater is steadily decreasing due to extensive agricultural demand irrigated lands. Therefore, resources should be used with greater efficiency, and use non-traditional resources, such as Treated Wastewater (TW), increased. Reusing TW could an alterna...

Cyanobacterial blooms often occur in aquaculture wastewater in China. A floating plant, water hyacinth has been widely used to treat this wastewater. Little is known, however, about bacterial community characteristics and the risk of potential pathogens in cyanobacteria-blooming aquaculture wastewater remediated by water hyacinth. In wastewater treated with water hyacinth, we used culture enume...

Many communities and villages around the world face serious problems with lack of sanitation especially in disposing of the wastewater-black water and grey water from the houses, or wash outs from animal rearing sheds. Across the world diverting wastewater to the surroundings or to the public spaces are not uncommon. This is responsible for contaminating drinking water sources causing health ri...

Exploiting microalgae as feedstock for biofuel production is a growing field of research and application, but there remain challenges related to industrial viability and economic sustainability. A solution to the water requirements of industrial-scale production is the use of wastewater as a growth medium. Considering the variable quality and contaminant loads of wastewater, algal feedstock wou...

This paper shows the real situation about management of water and wastewater in Lebanon and focuses on problems related to urban water pollution released in environment. Water and wastewater infrastructures have been rebuilt since 1992. However, wastewater management still remains one of the greatest challenges facing Lebanese people, since water supply projects have been given priority over wa...

with the development of the wastewater treatment plants and the increase in volume of treated wastewaters in our country, it is necessary to use treated wastewater wisely. landscape irrigation and agriculture applications considered as a significant scope for the treated wastewater. in this paper, the advantages and disadvantages of these applications are investigated and the importance of the ...

Tracking and determining the amount and types of urban sewage that is being releasing to the environment is important in planning for wastewater treatment systems and water quality control. In this research, in four stations of Anzali Lagoon, (by means of a gas chromatograph device with mass detector spectrometer) wastewater pollution has been measured and evaluated with molecular indicator Lin...

the precipitation of calcium carbonate by bacteria isolated from submerged fixed-film bioreactorused for the treatment of urban wastewater in both natural and artificial media was studied. however, carbonate precipitation was detected only when the bacteria grow in media added with calcium. precipitation took place rapidly, and crystal formation began 3 d after inoculation and the percentage of...
