캘리포니아의 Padre 댐 지자체 용수구역이 물 공급의 다양성을 도모하는 방법의 일환이자 수입 물에 대한 의존성을 줄이려는 목적으로 샨티 시에서 새 수지원을 찾아내기 위해 향상된 수 처리 플랜트 프로젝트를 시작할 것으로 밝혔다.

기금으로 모인 시범 프로젝트는 향상된 물 정화 기술을 적용하면서 간접적인 음용가능 재사용 시설의 건설과 설치를 이끌어낼 것이다.

 

 

 

Padre Dam Municipal Water District of California has announced that it will begin an advanced water treatment plant project to explore a new source of water in the city of Santee as a means to diversify its water supply, while also reducing its dependency on imported water.

 

A demonstration project -- funded by a grant -- will result in the construction and installation of an indirect potable reuse facility, utilizing advanced water purification technologies. The treatment process will include: chlorine disinfection, coagulation, ultrafiltration, reverse osmosis (RO) and advanced oxidation.

 

Biwater, a global provider of large-scale water and wastewater solutions, will provide a complete turnkey design and supply and commission all process, mechanical, electrical, and control components for the plant. The company was chosen for its ability to supply a fully integrated system on a fast-track delivery.

 

In addition to the chlorine contactor, ultrafiltration and RO system, and advanced oxidation process system (using ultraviolet (UV) light and oxidation), the project will include field pumps, a chemical dosing systems, programmable logic controller (PLC) and instrumentation, motor control centers, and electrical panels.

 

The new facility will treat secondary effluent from a wastewater treatment plant in the District, and the treated water will be used for demonstration and testing purposes to ensure it meets or exceeds the California Public Health Department's draft regulations.

 

Following commissioning, the demonstration project will run for a period of one year. In parallel, studies will continue to assess the capacity of the Santee basin aquifer and the feasibility of extending the project beyond the demonstration and testing period to serve a larger customer base in California.

 

After the testing period, the District hopes to be able to expand the facility and to construct a full-scale plant to provide up to 10 million gallons per day of treated water with indirect potable reuse potential. With the necessary approvals to proceed, treated water would be injected into the local groundwater basin. It would undergo natural filtration, be withdrawn, treated again, and then distributed as potable water to customers.
