Abstract

Water is one of the important elements in a process plant. It is the most effective thing to be used as the coolen in plant. As we know, from total water usage in the world, 20% of the amount is used in the industry field. Only 2.5% water in the world is considered as fresh water while the rest is salt water. Almost 80% of diseases in so called developing countries are associated with water, causing some three million early deaths. The world's industry currently is enforced to concern regarding the sustainability issue. They need to ensure that all the aspects that is related to the enviromnent' s issue is being concerned frrst before considering other factors. It would give the impact on the cost of the fresh water if it is not being controlled. Recently, many studies regarding the system to recycle and reuse waste water had been conducted. Those ideas come in line with the current situation that occur all over the world which is water crisis. In Malaysia, eventhough we are receiving a big amount of rain water every year, we need to aware that the world is changing and sometimes it is out of our expectation. Prevention is better than cure. Synchronize with that, there are several group that are currently did the research for this and come up with a system to be implemented. For example, in Universiti Teknologi Malaysia, a system to recycle and reuse the waste water from the mosque is being implemented. It shows that by doing so, we could save lots of water by using it effectively .To perform this study, main research element to be use is Water Cascade Analysis (WCA) and following its steps. It is a new method to determine the minimum water and wastewater targets for water using processes. Therefore, this system will be use for this project will be a combination of research element from previous case problems and also to create new design in recycling and reusing the waste water to be used as the source of cooling tower water. The study would be based on the waste water specification from Final Check Basin (T-610) in waste water plant in one of the petrochemical waste water treatment plant in Malaysia.
