An effective drinking and pool water disinfection is the most important public health reponsibility. The raw water obtained from natural sources is treated by using three basic steps: sedimentation, ventilation and filtration. With good treatment, the number of bacteria in water can be reduced by 99.5%. The water must be disinfected after pretreatment. Disinfection is generally carried out by chemical, physical or mechanical methods. The chemicals used in the disinfection process are chlorine and chlorine compounds, bromine and iodine compounds, ozone, phenol and phenolic compounds, alcohols, various dyes, soaps and synthetic detergents, ammonium compounds, hydrogen peroxide, various alkalis and acids. The use of heat and light are physical disinfection methods. With in these methods, chlorination is the most common, effective and cheapest disinfection method of water. At the same time, it is an effective microbiocide against all water-borne pathogens, although it can cause by-products after disinfection of drinking or pool water disinfection. In general, other disinfection methods are used as a supplement.

Intestinal parasites comprise major health problems, especially in the tropical and sub-tropical regions. In developing countries, it is estimated that some 3.5billion people are affected, and that 450 million are ill as a result of these infections, the majority being children. Cross-sectional hospital-based study. It was conducted in Alribat University hospital, Khartoum State and aimed to estimate the distribution of Intestinal parasites among the patients in the study area. 120 stool samples were collected and analyzed by direct saline stool preparation and formal-ether Concentration Technique. Results showed that, 75(62.5%) stool samples were positive by the formal-ether Concentration Technique. While 55(45.8%) were positive by the direct saline stool preparation. Intestinal parasites were more prevalent among the male patients (65.7%) than the females (57.4%). Furthermore, they were more prevalent among the age group 5 to 10 years old (85%). The study concludes that Intestinal parasites were more prevalent among the male patients and among the age group 5to 10 years old. The study recommends using formal-ether Concentration Technique for diagnosis of Intestinal parasites.
