of the presence of residual coagulants in treated water increases.
In most water treatment plants, variation in raw water quality and
the quantity make necessary a good monitoring of the optimum
condition of treatment. In spite of these, consumers are exposed
to dangerous consumption of residual coagulant in drinking
water. There are numerous studies about these metals associated
with various health problems and obstructing water distribution
networks.

Coal is a substance that we use to heat something like dish or
boiling water. But the main problem in this situation is how to
reduce smoke during coal burning. However, normal coals have
their disadvantages. These are several problem that can be listing
are black mark if touch it, too much smoke and need flame to
make sure the coal is burning. Human factor are using to make
sure the coal is heat and burning such as controlling air
ventilation. We got an idea to produce a new coal to solve the
problem. The appearance of the new coal is design in a small
size than ordinary coal. The processes to produce this coal are
more easily and take short time. It is a new invention created by
us to replace the ordinary coal. The ordinary processes to
Description produce coal are using trees that we need cutting down trees.
Now, we save the environment by using wastage material. We
have thought an alternative to find overcome the problem why
the ecosystems are destroyed by human beings. The coal is
create by us is using wastage coconut shell and others ingredients
to reduce wastage product and pollution. We have maximized
use of coal and minimized the cost. The advantages of this
project are eco friendly because it is produce by using wastage
material. The coal does not produce flame and smoke. Its
temperature can be reach until 510°C .The coal can be heated in
7 to 8 hours without depend human factor. Ventilation air is one
of main factor to helping process of burning to become long
lasting. It is portable to bring anywhere .If touch the dry coal
doesn’t leave any mark on hand.
