Document Description
Prior to placing newly-completed well #27 into service, iknstallation of a wellhead treatment plant is required. The treatment process selected is coagulation and filtration through three pressure filters located next to the well. It will use typical water treatment chemicals such as caustic soda (1,000 gallon day tank), ferrice chloride (500 gallon day tank), and acid (1,500 gallon day tank) to insure proper plant operation. It is anticipated that about 13 truck delivers per year will be made to supply the above chemicals. Sodium Hypochlorise will be added from existing facilities. After the chemicals are added, an inline statice mixer will mix the water, and then the water will flow into the three pressure filters. Following treatment, the water will enter an existing reservoir. On demand the wayer will be pumped out the reservoir and into the distribution system. Once a day the three filters will be backwashed and the backwashed water will be sent to a backwash tank. In the tank solids will settle out and majoritt of the water will be recycled back to the head of the plant. When a certain amount of solids has accumulated over time they will be removed by vaccum truck approximately four times year and disposed of in a proper manner.
