應用先進的海水化淡技術 Embracing State-of-the-Art Desalination Technology 將軍澳海水化淡廠採用的「雙過濾」逆滲透海水化淡技術，目前已經過充分驗證且廣泛應 用。現時全球以海水化淡技術生產的食水有超過百分之六十經由該技術生產。 逆滲透的過程中利用了高壓擠壓來自海水的原水穿過半透膜成為純水。逆滲透膜只供水份 子穿過，而原水中溶解鹽類、有機物質及病毒等均不能穿過。在第一次的逆滲透過濾過程 中，經初步處理的海水將穿過半滲透膜，從中去除超過99.5%的鹽份、細菌、病毒和其 他雜質，潔淨後的水（又稱為「滲透液」）將經由收集管收集並再次進行第二次的逆滲透 過濾程序，進一步去除水中的鹽份。 利用太陽能板發電場產生可再生能源 Renewable Energy Generation via Solar PV Farm 我們現正計劃在海水化淡廠鄰近的堆填區上興建10 兆瓦的大 型太陽能板發電場，配合早前在大樓屋頂上安裝的一千八百多 塊太陽能板，源源不絕為海水化淡廠提供可再生能源。 A large-scale solar photovoltaics (PV) farm with a power generation capacity of 10 Mega-watts is being planned for installation on the top of a nearby landfill. Over 1 800 roof solar panels have been installed to generate renewable energy for the plant's use. 10 兆瓦的大型太陽能板發電場 Mega-watts power generation capacity 1800 屋頂太陽能板 roof solar panels 現場氯氣生產大樓上的綠化屋頂，以及逆滲透淨化大樓屋頂上的太陽能板。 Green roof on top of the On-site Chlorine Generation Building and PV panels on the roof of Reverse Osmosis Building. The TKODP adopts a "double pass" RO desalination technology, a well-proven and widely used technology which accounts for more than 60% of global desalination production. RO is a process of forcing water from seawater through a semi-permeable membrane under high pressure to become pure water. The RO membranes allow only water molecules to pass through while dissolved salts, organic matter and virus, etc are retained. In the first Pass RO, pre-treated seawater will pass through membranes to remove over 99.5% of salt, bacteria, viruses and other impurities, allowing clean water (also known as "permeate") to enter the collection tube which will then undergo further RO treatment via the second Pass RO to enhance salt removal. 將軍澳第一期海水化淡廠設有12組逆滲透組 件，逾2300個白色玻璃纖維壓力容器。每個容 器內有7 個螺旋半滲透膜構件，海水會泵至該 容器並進行一系列的過濾程序淨化成食水。 The first stage of the TKODP has 12 RO racks with over 2 300 white fibreglass pressure vessels. Each vessel contains 7 spiral RO membrane elements through which seawater is pumped to remove impurities for providing drinking water after a series of treatment.
