The Desolenator Producing Clean Water Reading Answers
A
Traveling around Thailand in the 1990s, William Janssen was impressed with the basic rooftop solar heating systems that were on many homes, where energy from the sun was absorbed by a plate and then used to heat water for domestic use. Two decades later Janssen developed that basic idea he saw in Southeast Asia into a portable device that uses the power from the sun to purify water.
B
The Desolenator operates as a mobile desalination unit that can take water from different places, such as the sea, rivers, boreholes, and rain, and purify it for human consumption. It is particularly valuable in regions where natural groundwater reserves have been polluted, or where seawater is the only water source available.
Janssen saw that there was a need for a sustainable way to clean water is both the developing and the developed countries when he moved to the United Arab Emirates and saw large-scale water processing. 'I was confronted with the enormous carbon footprint that the Gulf nations have because of all of the desalination that they do,' he says.
C
The Desolenator can produce 15 liters of drinking water per day, enough to sustain a family for cooking and drinking. Its main selling point is that unlike standard desalination techniques, it doesn't require a generated power supply: just sunlight. It measures 120 cm by 90 cm, and it easy to transport, thanks to its two wheels. Water enters through a pipe and flows as a thin film between a sheet of double glazing and the surface of a solar panel, where it is heated by the sun. the warm water flows into a small boiler (heated by a solar-powered battery) where it is converted to steam. When the steam cools, it becomes distilled water. The device has a very simple filter to trap particles, and this can easily be shaken to remove them. There are two tubes for liquid coming out: one for the waste - salt from seawater, fluoride, etc. - and another for the distilled water. The performance of the unit is shown on an LCD screen and transmitted to the company which provides services when necessary.
D
A recent analysis found that at least two-thirds of the world's population lives with severe water scarcity for at least a month every year. Janssen says that be 2030 half of the world's population will be living with water stress - where the demand exceeds the supply over a certain period of time. 'It is really important that a sustainable solution is brought to the market that is able to help these people,' he says. Many countries 'don't have the money for desalination plants, which are very expensive to build. They don't have the money to operate them, they are very maintenance intensive, and they don't have the money to buy the diesel to run the desalination plants, so it is a really bad situation.'
E
The device is aimed at a wide variety of users - from homeowners in the developing world who do not have a constant supply of water to people living off the grid in rural parts of the US. The first commercial versions of the Desolenator are expected to be in operation in India early next year, after field tests are carried out. The market for the self-sufficient devices in developing countries is twofold - those who cannot afford the money for the device outright and pay through microfinance, and middle-income homes that can lease their own equipment. 'People in India don't pay for a fridge outright; they pay for it over six months. They would put the Desolenator on their roof and hook it up to their municipal supply and they would get very reliable drinking water on a daily basis,' Janssen says. In the developed world, it is aimed at niche markets where tap water is unavailable - for camping, on boats, or for the military, for instance.
F
Prices will vary according to where it is bought. In the developing world, the price will depend on what deal aid organizations can negotiate. In developed countries, it is likely to come in at $1,000 (£685) a unit, said Janssen. 'We are a venture with a social mission. We are aware that the product we have envisioned is mainly finding application in the developing world and the humanitarian sector and that this is the way we will proceed. We do realize, though, that to be a viable company there is a bottom line to keep in mind,' he says.
G
The company itself is based at Imperial College London, although Janssen, its chief executive, still lives in the UAE. It has raised £340,000 in funding so far. Within two years, he says, the company aims to be selling 1,000 units a month, mainly in the humanitarian field. They are expected to be sold in areas such as Australia, northern Chile, Peru, Texas, and California.

Question 21
Answer: wheels
Supporting Sentence: It measures 120 cm by 90 cm, and is easy to transport, thanks to its two wheels
Keyword : device, used, different locations
Keyword Location: Paragraph C, 3rd sentence
Explanation: Section C explains how the desolenator works. It states that the measurement is 120 cm by 90 cm, and is easy to transport. The author also thanks to its two wheels. It can be used in different locations means
it is use to use. The feature that makes this possible is its ‘two wheels’. However, as we can only use ONE WORD, the answer must be ‘wheels’.
Question 22
Answer: film
Supporting Sentence: Water enters through a pipe and flows as a thin film between a sheet of double glazing and the surface of a solar panel, where it is heated by the sun.
Keyword : water, fed, pipe, flows, solar panel
Keyword Location: Paragraph C, 4th sentence
Explanation: The passage states that water enters through a pipe, and flows as a thin film …… of a solar panel”. After water enters a pipe (or is ‘fed into’ a pipe), a thin film of water flows out, between ‘a sheet of double glazing and the surface of a solar panel’. This makes film the correct answer.
Question 23
Answer: filter
Supporting Sentence: The device has a very simple filter to trap particles, and this can easily be shaken to remove them.
Keyword : any, particles, water, caught in
Keyword Location: Paragraph C, 7th sentence
Explanation: We can paraphrase the supporting sentence into the passive voice as ‘particles are trapped/caught in a very simple filter’. Hence, the correct answer is ‘filter’.
Question 24

Supporting Sentence: There are two tubes for liquid coming out: one for the waste - salt from seawater, fluoride, etc. - and another for the distilled water.
Keyword : purified, water, tube, types, through another
Keyword Location: Paragraph C, 8th sentence
Explanation: Purified means distilled. This sentence distinguishes between two types of liquid that come out through two different tubes. The term ‘distilled water’ is synonymous to ‘purified water’, so the other type of liquid must be ‘waste’.
