Principles and Approaches for Drinking Water Treatment Plant Performance Assessment and Optimization
The benefits of process optimization are well recognized in the cost-effective operation of a water treatment plant and deferment of capital cost. Several methodologies have been developed internationally to guide the assessment process. In South Africa, for compliance with the Blue Drop criteria, water services institutions are required to compile a plant-specific process audit on an annual basis which also informs the risk management plan. The objective of the process audit is to ensure that the current treatment plant remains adequate to sustain compliance of the final product with regulatory requirements. The process audit is considered a subset of the optimisation assessment as optimization and cost savings are not specifically addressed, with the exception of water losses and energy efficiency.

Water treatment-2017
Water treatment is any process that makes water more acceptable for a specific end-use. The end use may be drinking, industrial water supply, irrigation, river flow maintenance, water recreation or many other uses, including being safely returned to the environment. Water treatment removes contaminants and undesirable components or reduces their concentration so that the water becomes fit for its desired end-use.

Water Treatment
Today the City of Houston has plenty of water and has won awards for its water quality accomplished through water treatment plants, according to city officials. Jeff Taylor, Houston’s Public Works director (2006), says the emphasis is on water quality rather than water supply in Houston because the city receives about 50 inches of rainfall a year and has a 30-to-50-year supply. However, Jim Adams, general manager of the San Jacinto Water Authority and chair of Region H Water Planning Group (Region H includes Houston), says by 2060, Houston will require three billion gallons of water a year. “We are going to have to reuse water and we are going to have to conserve,” says Adams. “Water is not as plentiful as it used to be.”

Water Treatment Session Objectives
All surface water and some groundwaters require treatment prior to consumption to ensure that they do not represent a health risk to the user. Health risks to consumers from poor quality water can be due to microbiological, chemical, physical or radioactive contamination. However, microbiological contamination is generally the most important to human health as this leads to infectious diseases which affect all populations groups, many of which may cause epidemics and can be fatal. Chemical contamination, with the exception of a few substances such as cyanide and nitrate, tends to represent a more long-term health risk.

Water Treatment for Dialysis
Important because dialysis patients are exposed to water in dialysis in the amount of 6-800 cc/min. This equates to 192 liters per treatment. Shortly after dialysis became commonplace, the first cases of poisoning of dialysis patients by water impurities were reported. 1968 Aluminum dementia, Denver CO.

Water Treatment and Supply in Kayes, Mali, West Africa: Treatment Processes, Operations, and Economics
A high quality and sufficient water supply is essential to human health, but is often missing in life in West Africa. In Mali, only 65% of the population has access to improved drinking water sources (CIDA, 2002). As Sogoba Togota, Peace Corps Mali’s Associate Director of Water/ Sanitation says, “When entering a town or village to look at its health situation, it’s more telling to see if there’s a water tower than to count the number of hospital beds.” In this report, research was performed at the Drinking Water Treatment Plant in Kayes, an isolated city of 100,000 people in western Mali.
