2. Abstract
Poverty highly affects the health condition of a certain individual. Everyday,
everybody needs water to sustain their body with good health. Nowadays, water shortage
is very common among regions. Some uncivilized cities gets their supply of water from
wells, water pump, or by digging not knowing if it acquires a 100% potability. With the
current dilemma developing, the researchers came up of constructing a utility model of a
water purifier in order to combat this cause knowing that the availability of materials is at
hand locally and indigenously.
• Is Carbon really an effective source that can purify water?
• Yes, it works with the process called adsorption in which it makes pollutant molecules in
the fluid to be treated, entrapped inside the pore structure of the carbon substrate.
• Would/Can it purify water from water pumps or shallow wells and give a consistent
potability?
• Basically it can provide drinkable water by following the process exactly and by making
sure that the materials used, may it be indigenous or not is clean and safe to use.

3. INTRODUCTION
• True, water is something that people couldn’t live without. As for
planet earth, three fourths (3/4) of its body is comprised by water---
same to human beings and other living things. In view of this, the
researchers see a lot of concern as to the potability which is the
primary matter of finding innovative ways. The researchers decided to
find ways and means on how to address those concerns. From data’s
gathered, the researchers had come up to the conclusion for the
development of a utility model of a water purifier. Indeed this might
as well serve as a solution as per needs of eradicating water borne
diseases. With this, water plays a major role for life.

4. STATEMENT OF THE PROBLEM
• Why settle for a very expensive water purifier when people would
know how to construct one easily with the aid of observations and
testing? With this at hand, the researchers had come up to the
following questions:
• General Question:
Is the product effective enough to purify water?

5. STATEMENT OF THE PROBLEM
• Specific Questions:
• Are the materials to be built available?
• Is it affordable enough compared to other commercialized purifiers or
other water purifier improvisations?
• Can it be used daily without affecting its durability?
• Is Carbon really an effective source which contributed much to the
aforementioned water purifier?

6. OBJECTIVES
General Objective:
• To build a utility model of a water purifier using activated carbon as alternative source.
•
Specific Objectives
• To construct a system of low cost.
• To know if the product is effective or safe to use.
• To know how much activated carbon is needed in order to make the product function
properly.
• To know how much volume of water it can fill in a certain period of time.
• To successfully observe if it purified the water to a 100% potability.

7. SIGNIFICANCE OF THE STUDY
• For the past decade until these days, so much pollutant has penetrated to
water sources for human and animal consumption. Admit it or not but the
truth is even the Water district that is supposed to supply potable water to
the populace doesn’t even deliver it to a 100% potability. much more on
the rural and sub-urban areas wherein the water supply depends only on
shallow wells. Hence, water borne diseases are basically rampant as per
data’s taken by health centers. From this point of view, the researchers
decided to construct a system to address this common problem. This is a
system the researchers decided to call as a utility model of a water purifier
using activated carbon as alternative source to serve as a multi-faucet as to
serve not only for safe drinking, but also to cover both bath and laundry to
a certain household

8. SCOPE AND LIMITATIONS
• The utility model of a water purifier can be built in one day. Indigenous but
clean materials can really help for the financial demands in making the
product. Prior to the product’s effect, it can only purify a form of water. Not
juices, alcohols, or soft drinks. The researchers experimented on purifying
soft drinks and alcohols and the result was placid just like the result of
purifying normal water. But, despite of the physical characteristics
observed as the researchers tried to purify the soft drinks and alcohol, the
water purified left an insignificant odor which means that there is still
chemicals left at the water. It signifies that the product is only appropriate
and applicable to water---and not any other variants. The product’s
extremity is mainly focused in purifying non potable drinking water and not
for other liquids. Thus, it pertains that in order to observe the safeness of
the product, water should be the only one tested and experimented

14. In Table 1, it shows the results about the pH Level (Base) of the water
that was purified by the product. Using a litmus paper, the researchers
have detected if the water contains any acid or base. The pH Scale goes
from 0-14. Acids have pH values between 0 and 7 and bases have pH
values between 7 and 14. Consistently, on the first trial up to the third
trial, the red litmus paper didn’t change its color---which means that
the pH Value is 7. With its result, the water purified is neutral

16. • In Table 2, it shows the results about the pH Level (Acid) of the water
that was purified by the product. On the first trial up to the last trial,
there was no acid in the water after the researchers found out that
the blue litmus paper didn’t change its color in each trial. With no
contradiction to the pH Level of the Base, the result was neutral
which means it has a pH Scale of 7 making the water safe to wash
with your hands or do the laundry.

18. • In Table 3, it shows how much water is needed to supply the day
tank. With the three pails supplied, the activated carbon can purify
the water. It is because that the process called adsorption makes
pollutant molecules in the fluid to be treated, entrapped inside the
pore structure of the carbon substrate. If only one to two pails are
filled inside the day tank, the water won’t be effectively purified
making it not potable to some extent.

Summary, Conclusions and Recommendations
• Summary
• The study bore a good result of making a Utility model of a
Water Purifier. Nowadays, water plays a very important role to
people. Unclean water contributes a dilemma if it is widely spread
and not purified. With the water purifier, it can reduce the chance of
having communicable diseases, unpleasant surroundings, and
morbidity. The study successfully met the expectations of it being
effective. With the aid of indigenous materials, the water purifier will
be affordable making it also useful in purifying water.

22. Conclusions
• The researchers had concluded that the Utility Model of a Water
Purifier is truly beneficial to the environment. With water one of the
world’s major problems; this purifier can help the world become pleasant
and clean. The group also concluded that it can purify water using three
pails supplied at the day tank. It also can purify water making it safe to
drink, or to wash hands. Its pH Scale is 7 which means it is neutral making it
clear that it is clean and pure. The product successfully met the desired
expectations that it is inexpensive, effective, environmental-friendly, and it
can cleanse stagnant water. This concludes that it is safe to use, free from
harm and prevents the spreading of unpurified water used throughout the
region. Many people can be a benefactor of this product for it saves time,
money, and effort. With just the presence of carbon, the process can be
done cleanly making the model work successfully, cleansing harmful
substances.

23. RECCOMENDATIONS
• If the people wants to make the world a better place to live at, this
purifier is one solution. With the major problem in the community
raging and continuously spreading internationally, many
disadvantages are likely to occur due to the fact that water can
transmit diseases and make the environment not friendly enough to
humanity. By using the purifier, the following recommendations are
further expected:

24. • Indigenous Materials are required in order to save and refrain from
high prices. But make sure it is clean and safe to use.
• Make sure to supply the day tank every time the purifier will be used.
• Check every pipe if it has holes.
• If a sample of the dirty substances is required, open the Drain Valve.
• If there is no plastic can to act as the day tank, use a water container
or the container which is the same at the supply tank instead.
• Never try alcohols like beers on the water purifier for it can not be
purified well due to the product’s extremity.
