Study of an existing water treatment plant of simple design and operating system for supplying drinking water to rural communities in the lower Mekong Basin countries

THE DATA AND INFORMATION GATHERED ARE RELATED TO LOADING, OPERATIONAL DIFFICULTIES, OPERATION COSTS AND INCOME, PROCESS EFFICIENCY AND THE POPULATION AND SOCIETY OF THE VILLAGE SERVED. THE SLOW SAND FILTER SELECTED FOR STUDY WAS LOCATED AT KRANUAN IN THE NORTHEASTERN PART OF THAILAND. DATA COLLECTION WAS CARRIED OUT FROM JUNE 1975 TO APRIL 1976. THIS STUDY IS SIGNIFICANT IN THAT THE WATER TREATMENT PROCESS IS APPLICABLE TO RURAL COMMUNITIES WHERE MODERN TECHNIQUES AND QUALIFIED OPERATORS MAY NOT BE AVAILABLE.
