Drinking Water Quality - PUB, Singapore's National Water
Drinking water is normally clear but very occasionally may appear discoloured or contain particles. This may be caused by essential maintenance operations such as the routine cleaning of water tanks, flushing of service pipes in buildings and testing of fire hydrants.
Primary treatment devices reduce the velocity and disperse the flow of wastewater. In primary treatment the velocity of flow is reduced to 1 to 2 feet per minute to maintain a quiescent condition so that the material denser than water will settle out and material less dense than water will float to the surface.
Potable water treatment: 4.2 Preliminary treatment
Potable water treatment . 4.2 Preliminary treatment. The abstracted water is first screened to remove suspended and floating debris, such as leaves or branches, which could interfere with the operation of machinery in the treatment works. The water may then enter a preliminary settlement tank or storage reservoir.
water. Possible uses and disposal options for the concentrated brine and potable water are outlined. In order for hydrate-based treatment technologies to be implemented into industry, crystal size and quality of the gas hydrates need to be determined. Therefore, investigations regarding such properties should be conducted.
Examining the economics of seawater desalination using the
fresh water and especially potable water is jeopardizing life in many regions of the world [1]. By 2025, about two-thirds of the world population may suffer from high or moderate water shortages. Seawater desalination offers a promising option for the supply of potable water. Seawater desalination is an

Myanmar is one of the least developed countries in the world, and very little information is available regarding the nation’s water quality. This report gives an overview of the current situation in the country, presenting the results of various water-quality assessments in urban areas of Myanmar. River, dam, lake, and well water sources were examined and found to be of generally good quality.
Epidemiology and Control of Legionellosis, Singapore
To determine trends and clinical and epidemiologic features of legionellosis in Singapore, we studied cases reported during 2000–2009. During this period, 238 indigenous and 33 imported cases of legionellosis were reported. Cases were reported individually and sporadically throughout each year. Although the annual incidence of indigenous cases had decreased from 0.46 cases per 100,000

Background. Gastric cancer is one of the most common malignancies in the world, and radical operations have been accepted as the best choice for treating gastric cancer [].The development of surgical techniques and equipment in the past two decades has also improved the treatment of gastric cancer, which has in turn improved the survival rate and quality of life of the patients.
