چکیده
The objectives of this research work was to evaluate the reduction of THM precursors by cationic pDADMAC and determine the correlations between the chlorine demand and trihalomethane formation in the presence of electrolyte solutions and ambient light. The chlorine demand was found to be significantly reduced provided that the H2SO 4 electrolyte was fed to the sample solutions. The amount of CHCI 3 formation was also decreased when the Na2SO 4 electrolyte was introduced in spite of the levels of light intensity. The p-DADMAC can not only effectively remove the turbidity but also reduce the formation of CHCI 3. The optimum dosage of p-DADMAC for reducing the turbidity, TOC and CHCI 3 in the humic acid and source water samples was determined and depended upon the nature of organics. ©1999 Elsevier Science Ltd.

A new cell immobilization method based on the replacement of KC1 by KC1 +chitosan as gelling agent was developed. The results showed that through addition of chitosan into gelling agent, the mechanical strength and thermal stability of the carrageenan gel were greatly improved. The new immobilization method was used to entrap a chlorophenol-degrading microorganism. The immobilized microbial cel...

The occurrence and behavior of wastewater indicator compounds in the Santa Arm River (SAR) water and the underlying aquifer recharged by the SAR has been studied. The SAR contains a high proportion of tertiary treated wastewater effluents, up to 100% during summer and fall. The following water quality parameters were quantified: four specific wastewater indicator compounds, ethylene diaminetetr...

Multi-phase (more than three phases) drives possess several advantages over conventional three-phase drives such as: reducing the amplitude and increasing the frequency of torque pulsations, reducing the rotor harmonic currents, reducing the current per phase without increasing the voltage per phase, lowering the dc link current harmonics and higher reliability. By increasing the number of phas...

Performance evaluation of multiple-bus multiprocessor systems is usually carried out under the assumption of uniform memory reference model. Hot spots arising in multiprocessor systems due to the use of shared variables, synchronization primitives, etc. give rise to non-uniform memory reference pattern. The objective of this paper is to study the performance of multiple bus multiprocessor syste...
