The use of Potentiometric Mass Titration (PMT) technique for determining the acid-base behavior of activated sludge
Water and Wastewater Treatment
Activated sludge is a biological floc composed of microorganisms, organics, and inorganics and plays an important role in wastewater treatment. The pH of an activated sludge suspension determines the acid – base behaviour and the charge of the microorganisms in water. In the present study, the...
Cost analysis of seawater desalination using an integrated reverse osmosis system on a cruise ship
Water and Wastewater Treatment
The best method to treat seawater is known to be the use of reverse osmosis (RO) systems. The cost factor becomes the most important issue when using RO systems. Although quite costly, RO systems are essential systems for ships. As known very well, water is a critical resource on ships, especially...
Influence of mining and agricultural activities on the quality of groundwater from some rural areas of South-eastern Nigeria

Nitrate is a common groundwater pollutant all over the world. In some regions of Iran, its levels are high enough to cause serious problems to human health and the environment . The objectives of this work were to evaluate the efficiency of Fe-doped TiO 2 nanoparticles at removing nitrate from...
Impact of climate change on the runoff regime of an Eastern Himalayan river basin
Climate Change Impacts and Societal Adaptation in the Indian Subcontinent
The present study has been carried out for the trans-boundary Subansiri sub-basin of Brahmaputra river basin. Subansiri is the largest tributary of Brahmaputra within India and the river system has its practical importance as it holds a high water resources as well as hydropower potential for the...
Total dissolved inorganic carbon and physicochemical characteristics of surface microlayer and upper mixed layer water from Lagos Lagoon, Nigeria
Water Quality
The carbonate and physicochemical characteristics of the surface microlayer and upper mixed layer of a tropical coastal lagoon were investigated. Data on the physicochemical parameters generally indicated a moderately polluted ecosystem. The influence of the ocean environment over the Lagoon system...
