Loreni Martinez English 111 24thOctober, 2008 The Purification of Water Before water reaches the consumers tap or faucet, it goes through various treatment processes at the double run water treatment plan after it is drawn from the river. The double run treatment plant produces four point five million gallons of water per day which serves the need of Sand Hill, Max – Boro , Burell Boom, Ladyville, Belize city and up to eight mile on the western highway. The double Run Water Treatment Plant draws its water from the Belize River and employs these treatment processes which are Mixing, Coagulation and flocculation, sedimentation, filtration, disinfection, and distribution of water. In the case of river water the, BWS employs a much more complex treatment process. Firstly, the water is screened in order to take out the larger solid. The fine contaminants down to the molecular size are then removed with the use of chemicals to coagulate them and create floc, which settles relatively rapidly in the clarifiers. Once the majority of he material has settled, the water is further treated by filtering through anthracite and fine sand. At this point, water is now clear, but may contain disease causing bacteria. BWS disinfects the water by adding small quantities of chlorine, a chemical that is safe to humans, but has the ability to kill any bacteria, thus producing safe and healthy water for the consumers. In the purification of water the river water known as Raw- Water comes from the Belize River and goes into the intake well by gravitational force. The water is then pump from the intake well by intake pumps via the chemical building where the treatment process is started. The raw water along with aluminum sulphate and muriatic acid goes into the reaction chamber where coagulation, flocculation and sedimentation take place. After these processes eighty to ninety percent of the dirt is already out of the water. The next ten to fifteen percent dirt that is left is taken...
