Khurram Shahzad Baig
Dr. K. Shahzad Baig has spent his grad study period in Toronto, and it is responsible for shaping and molding him into the individual that he is today. This community has allowed him to realize the importance of inclusion and closeness of individuals.His doctoral dissertation looks at the use of the new methodology for the separation of active enzymes from the exhausted materials and reuses for the production of bioethanol (bioenergy) from lignocellulosic waste materials. Master’s research was on removal of heavy metals from industrial wastewater using agricultural waste materials. He is accredited for teaching at higher educational institutions (by SEDA-UK (British Universities). He has a license for practicing engineering (P. Eng.) in Canada, as well. During his professional life, he was fortunate to have worked in research areas that he was deeply passionate about – materials, energy, environment (sampling and analysis, air pollution control, water and wastewater treatment, unit operations, etc.) and sustainability. He is proud to be a member of a team who gave remedial solution for the problem of Bromate contamination (carcinogenic) in drinking water at the Emirate of Abu Dhabi. The recommendations were applied to the second largest water treatment unit of the world and successfully achieved the acclaimed results. The results of this research were presented internationally as well at the EUROMED 2006 conference in Montpellier-France in May 2006. Similarly, he has presented the results of his research works in various international conferences and public seminars, and some of the results are published in peer-reviewed high-impact journals. According to the stats presented by OMICS, one of his articles on emissions from coal fired power plants has been downloaded over 46,000 times (till now). His involvement in research has skilled him in developing, and commissioning of labs. In his free time, he serves as a reviewer for some research journals. His cross-cultural study, training, teaching and other comparable experience has given him the competence to interact with people from different ethnic, socioeconomic, geographic backgrounds.Apart from his educational and research activities, his leadership skills also involve serving his community such as: i) Director of Licensure Assistance Program at Professional Engineers Ontario (PEO), Canada, ii) Chair, Education Outreach Committee of East Toronto Chapter PEO, Canada iii) VP Ed at Grosvenor Toastmasters at Toronto, Canada, iv) Member of Ryerson University Senate, Toronto, Canada, etc.

Papers by Khurram Shahzad Baig
power plants are one of the sources of SOx, NOx and mercury emissions. These emissions have serious impact on
the health of neighboring people such as increased rates of premature death, to the exacerbation of chronic respiratory
diseases. The objectives of this review article are:
i) To identify the issues of air pollution and the environmental impact of coal fired power plants,
ii) To discuss techniques and equipment that can contribute to improve the environmental sustainability.
The objectives were tackled by going through extensive literature review, field observations, and attending the
applicable meetings and conferences. The research outcomes show that coal will continue to be the key energy source
in some countries in the next 20 years, because the reserves of coal with them are relatively high. Such countries have
to undertake special considerations to minimize the bad impact on the local and global environment. The most important
problem to be solved is to limit the emissions (particulate matter, nitrogen oxides, sulfur oxides, carbon oxides, etc.).
In order to achieve reduction in the emissions it is necessary to apply advanced and efficient technologies. This article
presents functioning of a coal fired power plant, discuss environmental impacts and recommend technologies to make
coal fired power plants environmentally sustainable.
Bromate (BrO3-) is suspected as a carcinogen to human beings while being mutagenic and carcinogenic to rats and rodents. The urinary system in male rats was found to be more sensitive to attack with cancer due to chronic exposure to high concentrations of bromate in drinking water for lifetime. The WHO guidelines limit the maximum level of bromate ion in drinking water to 10 gL-1 (10 ppb).
In an initial step to study the bromate problem in potable water, samples of water from different locations in each one of ADWEA’s plants were collected and analyzed to find out bromate ion concentration. Bottled water samples were also analyzed for the same purpose. Results showed that the maximum allowable level of bromate in product water was exceeded by far allover ADWEA’s plants. Similarly, levels as high as 70 g L-1 were detected in bottled water samples collected from plants that use ADWEA’s water for further purification (particularly ozonation).
Possible solutions for the bromate problem are still under investigation on the lab scale. Short term solution relies on the production of sodium hypochlorite by the electrolysis of food grade salt (NaCl) solutions which are bromide-free.
Long term strategy requires research in a number of engineering and science areas where elimination of bromide ions from seawater upstream the electrolyzer or bromate removal after electrolysis is performed. Although replacement of the existing electro-chlorination systems in ADWEA’s plants is an alternative solution, economic design modifications to the existing plants would be preferable to combat bromate contamination of drinking water.
This paper outlines the basic features of hypochlorination process and hypochlorination plants in use by ADWEA. Research efforts done to date for developing efficient techniques for bromate removal from drinking water are summarized. Limitations of these techniques and possibility for implementation to eliminate bromate from ADWEA's hypochlorination systems are discussed.
Until a radical solution is developed to remediate bromate formation problem in drinking water, the short term and long term policies adopted by ADWEA to solve this problem and meet the WHO guideline are briefly outlined.
Finally, a proposal for process modification of the existing electrochlorination plants of ADWEA, to reduce bromate level to about 8 ppm in hypochlorite solution formed on the site is presented. The modified process, that needs research and verification, tries to keep using seawater as a costless and unlimited source of feed water to the electrolyzer.
