水质及过滤
We live in a world-class city, so it’s no surprise that our drinking water is among the best in the world. We protect our community by providing locally sourced, clean and safe drinking water to over 5 million people every day. How we do it takes a lot of science and dedication.

我们生活在一个世界级的城市，所以我们的饮用水是世界上最好的也就不足为奇了。我们每天为500多万人提供来自当地的清洁安全饮用水，以此保护我们的社区。我们如何做到这一点需要大量的科学和奉献。
It’s our job to make sure you have access to high-quality drinking water that tastes great and is safe to drink straight from the tap.
\r\nThere are lots of ways to produce safe drinking water. Most of the time, it involves a physical process (like filtering) and a chemical process (like balancing pH).
\r\nAll around the world people choose methods of producing drinking water that:
\r\n- \r\n
- are safe and reliable \r\n
- are cost effective \r\n
- achieve good quality water. \r\n
It's also important to consider the water source and tailor the process to suit it. The quality of the incoming water could be different because of:
\r\n- \r\n
- the types of activities in the catchment \r\n
- natural minerals in the water \r\n
- weather conditions, like droughts or high rainfall \r\n
- natural hazards, like bushfires. \r\n
In Sydney, we use modern water filtration and desalination plants. This ensures we achieve a consistent, high standard. Every drop meets the Australian Drinking Water Guidelines, which are some of the strictest in the world.

我们的工作就是确保你能直接从水龙头里喝到味道好、安全的高质量饮用水。
生产安全饮用水的方法有很多。大多数时候，它涉及一个物理过程(如过滤)和一个化学过程(如平衡pH值)。
世界各地的人们选择生产饮用水的方法:
- 安全可靠
- 是否具有成本效益
- 获得优质的水。
同样重要的是考虑水源并调整过程以适应它。流入的水的质量可能不同，因为:
- 集水区的活动类型
- 水中的天然矿物质
- 天气状况，如干旱或多雨
- 自然灾害，比如森林大火。
在悉尼,我们使用现代化的水过滤和海水淡化设备。这确保了我们达到一贯的高标准。每一滴水澳大利亚饮用水指南这是世界上最严格的。

水过滤
- \r\n
- We use fine mesh screens to remove debris, like twigs and leaves. \r\n
- We adjust the pH to aid the filtration process. \r\n
- We add a solution (coagulant) that makes the smallest particles stick together to form larger flocs. This makes it easier to filter them out. \r\n
- We use filters made of tightly packed beds of sand and crushed coal to trap and remove the floc. We clean our filters several times a week and continuously monitor their performance to ensure your water quality always remains high. \r\n
- We carefully balance the pH of the water. \r\n
- We add small amounts of chlorine to protect the water from harmful pathogens. \r\n
As a final step, we add small amounts of fluoride to the water as a safe and effective way of preventing dental decay. It’s not part of the filtration process, but is done under the advice of NSW Health.

\r\n"}}" id="text-b9112a7abd" class="cmp-text">过滤步骤
- 我们用细网筛去树枝和树叶等碎片。
- 我们调整pH值以帮助过滤过程。
- 我们加入一种溶液(凝固剂)，使最小的颗粒粘在一起形成较大的絮凝体。这样可以更容易地过滤掉它们。
- 我们使用用沙子和碎煤制成的过滤器来捕捉和去除絮凝物。我们每周清洗过滤器几次，并持续监测其性能，以确保您的水质始终保持高水平。
- 我们小心地平衡水的pH值。
- 我们加入少量的氯来保护水免受有害病原体的侵害。
最后一步，我们在水中加入少量的氟化物，这是一种安全有效的防止蛀牙的方法。这不是过滤过程的一部分，而是在新南威尔士州卫生．

海水淡化
Desalinated water is excellent quality, meets the Australian Drinking Water Guidelines and is monitored by NSW Health just like all our drinking water.
\nUnlike rivers and dams, the amount of water in oceans isn't affected by changing rainfall.
\nDesalination can give us a reliable supply of drinking water. While the plant is operating, we can adjust the capacity based on our system's needs.

\n"}}" id="text-84b8b889fe" class="cmp-text">海水淡化厂使用反渗透膜从海水中提取淡水。这些膜是一种物理屏障，可以阻止溶解的固体，如盐，所以只有淡水可以通过。
脱盐水质量优良，满足澳大利亚饮用水指南并由新南威尔士州卫生就像我们的饮用水一样。
与河流和水坝不同，海洋中的水量不受降雨变化的影响。
海水淡化可以为我们提供可靠的饮用水供应。当工厂运行时，我们可以根据系统的需要调整容量。
