Proper assessment of water quality status in a river system based on limited observations is an essential task for meeting the goals of environmental management. Various classification methods have been used for estimating the changing status and usability of surface water in River basin. However, a discrepancy frequently arises from the lack of a clear(More)
Dissolved organic matter (DOM) in natural waters is a complex mixture of compounds and contains most of the reduced carbon in aquatic ecosystems. DOM is ubiquitous in surface water and cannot be easily treated or disinfected using the conventional treatment. DOM in the water samples from Semenyih River Water Treatment Plant were isolated and fractionated(More)
The electric utility industry throughout the world has been undergoing significant changes due to the process of deregulation. Under the deregulation scheme, electricity businesses have unbundled into three components: generation, transmission and distribution. The interaction among these components would be on pure commercial basis. In the case of(More)
This paper proposes a new method to allocate the cost pertaining to the transmission loss due to harmonics. The proposed method which is called Generalized Harmonic Distribution Factor uses the principle of proportional sharing method to allocate the losses among the transmission users. A simple 5-bus system is used to compare the proposed method with(More)
An extraction technique using tri-butyl phosphate was developed and validated for a speciation study of lead in aqueous environment. The extraction was found to be optimum at pH 9 – 11, shaking time of 2 – 5 minutes and 0.04M HNO3 as stripping agent. The validation criteria include recovery, linearity, accuracy, precision, instrument detection limit (IDL),(More)
Chlorination is the most important method of disinfection in Malaysia which aims at ensuring an acceptable and safe drinking water quality. The dosing of chlorine to surface water containing ammonia and nitrogen compounds may form chloramines in the treated water. During this reaction, inorganic and organic chloramines are formed. The recommended maximum(More)
The Linggi River drainage basin in Negeri Sembilan Malaysia is the major source of potable water for the townships of Seremban and Port Dickson. Water quality is threatened by industrial and commercial development taking place in the basin. This study investigated the concentrations and distribution of organic micro-pollutants and heavy metals within the(More)
In this study, carboxymethyl chitosan bound Fe3O4 magnetic nanoparticles was synthesized by the binding of carboxymethyl chitosan (CC) onto the surface of Fe3O4 magnetic nanoparticles, which was developed by using coprecipitating method. The CC-Fe3O4 nanoparticles was characterized by transmission electron microscopy (TEM), X-ray diffraction patterns (XRD),(More)
