There are many ways to purify water. Sterilight uses which method to sterilize water?
- A.
Reverse Osmosis
- B.
Micro Filtration
- C.
5 Micron Filter
- D.
Ultra Violet (UV)
Correct Answer
D. Ultra Violet (UV)Explanation
It uses ultraviolet light to alter the structure of DNA in bacteria and viruses to make them inactive. Sterilizing water is NOT the same as filtering water - filtering water only removes particles larger than the set filter size. Sterilight does use filters before UV to remove particles.Rate this question:

RO (Reverse Osmosis) which is a different method of water purification is often used in residential applications because it can produce high volumes of water and does not need a storage tank.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
False - as RO uses water pressure to force water through a very fine membrane it has a reduced capacity vs UV. Generally it needs a storage tank as it cannot produce enough water as the tap is turned onRate this question:

UV water sterilisation is very effective when treating water from a bore-hole that is not clear as it contains lots of particles.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
UV may not be suitable without some additional pre-filtration as if the water is very unclear those particles can reflect UV light and make it less effective. In such a situation Pennyware recommends the client first conduct a water analysis that we can arrange for the client. Thereafter we can recommend additional filtration if needed.Rate this question:
-

The Sterilight units have 2 pre filters before UV sterilisation. What is the first filter used for (the 5micron filter)
- A.
Remove chlorine taste
- B.
Remove viruses
- C.
Remove particles and dirt that is less than 5 microns in size
- D.
Remove particles and dirt that is more than 5 microns in size
Correct Answer
D. Remove particles and dirt that is more than 5 microns in sizeExplanation
a human hair is approx 75micron so this removes particles a lot smaller than human hair. A human red blood cell is about 5 micron in size. many bacteria and viruses are smaller than 5 micron and therefore UV is needed after filtering to inactivate them.Rate this question:
-
- 12.
The second pre filter in the Sterilight system is an activated carbon filter. What does it do?
- A.
Removes organics such as chlorine
- B.
Removes carbon from the water
- C.
Adds activated carbon to give water a better taste
- D.
Nothing
Correct Answer
A. Removes organics such as chlorineExplanation
Charcoal is carbon. Activated charcoal is charcoal that has been treated with oxygen to open up millions of tiny pores between the carbon atoms. The use of special manufacturing techniques results in highly porous charcoals that have surface areas of 300-2,000 square metres per gram. These so-called active, or activated, charcoals are widely used to adsorb odorous or coloured substances from gases or liquids. Â
The word adsorb is important here. When a material adsorbs something, it attaches to it by chemical attraction. The huge surface area of activated charcoal gives it countless bonding sites. When certain chemicals pass next to the carbon surface, they attach to the surface and are trapped.
Activated charcoal is good at trapping other carbon-based impurities ("organic" chemicals), as well as things like chlorine. Many other chemicals are not attracted to carbon at all -- sodium, nitrates, etc. -- so they pass right through. This means that an activated charcoal filter will remove certain impurities while ignoring others. It also means that, once all of the bonding sites are filled, an activated charcoal filter stops working. At that point you must replace the filter.Rate this question:

Does UV treat E Coli bacteria?
- A.
True
- B.

-
- 16.
Does a Sterilight UV system need an electrical connection?
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
A Sterilight UV system does require an electrical connection. UV systems use ultraviolet light to disinfect water by killing bacteria and viruses. In order for the system to generate the UV light, it needs to be connected to a power source. Without an electrical connection, the UV system would not be able to function and effectively treat the water. Therefore, the statement "True" is correct.Rate this question:

Many chinese equivalent units loose around 40% UV effectiveness after 3 months so a big difference in qualityRate this question:
-
- 19.
Why does the UV lamp need replacing?
- A.
It gradually loses its effectiveness but will still work after the recommeded replacement time but not at the most effective level to guarantee effectiveness in treatment
- B.
It suddenly loses its effectiveness and if not replaced on time will not work at all
Correct Answer
A. It gradually loses its effectiveness but will still work after the recommeded replacement time but not at the most effective level to guarantee effectiveness in treatmentExplanation
The UV lamp needs replacing because it gradually loses its effectiveness over time. Although it may still work after the recommended replacement time, it will not be at the most effective level to guarantee effectiveness in treatment.Rate this question:

-
- 21.
Why do you need to make sure a Sterilight UV system does not operate at higher than the recommended water inlet pressure
- A.
The inlet is too small
- B.
The UV dosing may be less effective as water will flow faster through the chamber than designed for at excessive water pressure and so water may not receive a sufficient UV dose.
- C.
There could be a risk of mechanical failure of a connection fitting or filter housing at higher than recommended pressures
- D.
The 5 micron filter is not designed to operate at pressures higher than 5bar
Correct Answer(s)
B. The UV dosing may be less effective as water will flow faster through the chamber than designed for at excessive water pressure and so water may not receive a sufficient UV dose.
C. There could be a risk of mechanical failure of a connection fitting or filter housing at higher than recommended pressuresExplanation
Operating a Sterilight UV system at higher than the recommended water inlet pressure can have several negative consequences. Firstly, the UV dosing may be less effective as water will flow faster through the chamber than designed for at excessive water pressure. This means that the water may not receive a sufficient UV dose, leading to ineffective disinfection. Additionally, there is a risk of mechanical failure of connection fittings or filter housings at higher pressures, which can result in leaks or breakages. It is also mentioned that the 5 micron filter is not designed to operate at pressures higher than 5bar, further emphasizing the importance of maintaining the recommended water inlet pressure.Rate this question:

How often should a client change the 5 micron pre filter and the carbon filter
- A.
It depends on the water quality and water source
- B.
Every 9000 hours
- C.
Every 3 months
Correct Answer
A. It depends on the water quality and water sourceExplanation

If a client paid R5 000 for a POU system and after a year paid R95 for a replacement 5 micron cartridge plus R155 for a replacement carbon filter and R790 for the replacement UV lamp, how much would it have cost the client for a whole year PER LITRE OF WATER used for drinking in the family, assuming the family used 5l of water per day each day of the year Based on your answer would the client have saved money or spent more money using the system rather than buying bottled water that cost R5/litre?
- A.
R3.31 per litre
- B.
R5.25 per litre
- C.
Client would have saved money (Saved R3 085)
- D.
Client would have spent more money (Spent R500 more) by installing a POU system
Correct Answer(s)
A. R3.31 per litre
C. Client would have saved money (Saved R3 085)Explanation
The cost per litre of water used for drinking in the family for a whole year can be calculated by adding up the costs of the replacement cartridges, filter, and UV lamp and dividing it by the total litres of water used. In this case, the cost would be (R95 + R155 + R790) / (5l/day * 365 days) = R3.31 per litre. Therefore, the client would have saved money by installing the POU system, as the cost per litre is lower than the cost of buying bottled water at R5/litre. In total, the client would have saved R3,085.Rate this question:

The Sterilight system is supplied with a 5 micron pre filter for removing sediment and particles. Will it remove a human hair? if so approximately how large is a human hair in micros?
- A.
Yes it will remove a human hair
- B.
No - a human hair is less than 5 microns
- C.
A human hair is approximately 75 microns (much larger than 5 micros
- D.
A human hair is around 2 microns (smaller) so will pass through the filter
Correct Answer(s)
A. Yes it will remove a human hair
C. A human hair is approximately 75 microns (much larger than 5 microsExplanation
A "micron" is an abbreviated term for "micrometer", or a millionth of a meter (1/1,000,000 meters). This is about .00004 inches. For Size comparison, a human red blood cell is about 5 microns across. A human hair is about 75 microns across (depending on the person). Bacteria can be between about .2 microns and 3 microns in size. Therefore the 5 micron filter removes most particles but UV sterilization is needed to inactivate bacteria and viruses less than 5 micron sizeRate this question:
