Pakistani Engineering Students Develop Filtration Device To Create Clean, Safe, Water

巴基斯坦工程专业学生开发过滤设备,提供安全饮用水

Experts say that Pakistan will face severe water shortages by the year 2025.Those who live in Lahore are already experiencing the some of its effects.Water supply problems are common in big cities like Lahore where pollution in some areas forces people to go to water filtration plants.

专家表示,到2025年,巴基斯坦将面临严重的水资源短缺。那些居住在拉合尔的居民已经受到了一些影响。供水短缺问题在拉合尔等大城市很常见,一些地区水质受到污染,人们不得不到过滤厂获取饮用水。

Sometimes I go four or five kilometers away from home for filtered water in hopes that I can find an open filtered water pump.

“有时我会到离家四五公里的地方想办法过滤水,希望能找到一个公用的过滤泵。”

Ali Mannan Tirmizi is studying electrical engineering in Lahore University of Management Sciences.With the help of his team, Tirmizi is working on creating an inexpensive filtration device anyone can use at home.

Ali Mannan Tirmizi正在拉合尔管理科学大学学习电气工程专业。在团队的帮助下,Tirmizi正致力于研发一种低成本的过滤设备,以便人们可以在家中使用。

We have made a very low-cost and effective filter which is very easy to use.The current system we are working on removes bacteria very well, and we are also trying to make it able to block viruses in the water as well.

“我们研制出了一种低成本同时很有效的过滤器,非常容易使用。我们目前正在开发的系统可以有效地去除细菌,我们也试图让它能够阻止水中的病毒。”

Many poor neighborhoods are not reached by safe water supplies,so we're working on a decentralized system that anyone can use to make the water at home drinkable.

“许多贫困社区都没有可以安全使用的供水系统,所以我们正在开发一个分散的系统,这样人们在自己家中,就能喝上安全的饮用水。”

Pine tree branches are used in the filter unit."We need decent-sized branches that have enough xylem vessel bundles.We cut that into two to three centimeter pieces and place it in the boiling water with chemical overnight.This becomes the base of our filter, and we continue working from there."

过滤过程中会用到松树枝。“我们需要体积适中的树枝,要有足够的木质部导管。然后把它们切成两到三厘米的木块,之后放入沸水中加入化学品,静置一晚上。这是过滤器的底座,然后我们会在此基础上进行其他的操作。”

As the water shortage problem gets more severe in Pakistan, this student-developed filter will become more important.

巴基斯坦用水短缺问题日益严重,该学生团队开发的过滤器将变得十分重要。
