Turbidity of seawater through sedimentation tanks, filters and other pretreatment, and then through reverse osmosis membrane treatment, mineralization and other processes, crystal clear fresh water through the pipe network for millions of households. April 23rd at 9 am, the city's single unit capacity of the largest desalination equipment - six horizontal desalination of the two phase of the project's first tons of seawater desalination unit began trial operation. Reporters learned yesterday from the six horizontal Water Service Company, the unit is currently running well.

Yesterday afternoon, the reporter went to the seawater desalination of the second phase of the project site, plant rumbling sound, empty, unit in the full automatic operation state; control room, the staff sitting in front of a computer screen real-time monitoring unit operation data. Instrument display, as of 2 pm yesterday, the host has been running for 15 hours and 30 minutes, the current output of about 410 tons per hour, basically in accordance with the unit design standards.

"According to the test, at present water quality and a phase of the project are basically the same, even because the equipment renewal, water quality is further improved, the production and operation of desalinated water has been connected to municipal tap water pipeline, the supply to the residents of the home." Six horizontal Water Service Company chief engineer, deputy general manager of Mao, told reporters that the test run will last for a week, if the unit is stable, the two phase of the project's first desalination unit will be officially put into operation.

According to reports, Liuheng Island, the daily water consumption at about 1.5 million tons, due to less rain, the daily supply of two major water reservoir water only at about 6000 tons, plus supply Xia Zhi and surrounding islands freshwater, Liu Heng water daily need to produce desalinated water about 1 million tons. "These two days of desalination water from the production of this unit of sea water desalination unit."

Compared to it is understood that the first phase of the project, the second phase of the project in the unit design pay more attention to energy saving, in the preprocessing phase, the second phase of the project to the filtered water volume larger, more sophisticated filtration of V type filter alternative one phase of the project of valveless filter. To ensure that the quality of effluent, the second phase of the project desalination water outlet hole sealed stamped with a design.

Hair and told reporters that the raw water drawn from the sea, after sedimentation tank preliminary sedimentation backward into the V type filter and multi medium filter for fine filtration, and then enter the seawater desalination host. After host of RO membrane treatment, leaving only high purity water, again by the mineral processing to enhance the desalinated water taste. Finally, disinfection, the supply of residents. The two phase of the seawater desalination project and the first phase of the water quality of the effluent are maintained at 0.01 ~ 0.03 turbidity, far below the 1 turbidity of the national standard of tap water.

It is reported that six cross 10 thousand tons of class seawater desalination project construction is divided into four stages, the second phase of the project investment about 1.3 billion yuan, in May 2011 began construction, construction scale for Nissan 30000 tons of fresh water, the first station of 1.25 million tons of units "water", the ongoing optimization design of the second phase of the project in the second group units. After the completion of the two phase of the project, the six horizontal desalination capacity will reach 50 thousand tons per day, can effectively ensure the six horizontal and the surrounding islands of industry, students
