Here are some techniques that can be used to purify water with different water quality problem:

• Number 1

Smelling Water: A technique that can be used to purify smelly water is the use of activated carbon or zeolite. Zeolite can absorb odors in water.

• Number 2

Salt Water: To purify water that is too salty, you can use Reverse Osmosis (RO) or Demineralization.

• Number 3

Water Containing Metals: A technique that can be used to purify water containing metals such as iron, copper, zinc, and so on is to use a precipitation process, filtering with zeolite or activated carbon, or using Reverse Osmosis technology.

• Number 4

Muddy Water: To purify muddy water, this can be done by filtering it with sand or activated carbon media.

• Number 5

Paddy Field Irrigation Water: Paddy irrigation canal water can be clarified by using a process of settling and filtering using sand and activated carbon media.

• Number 6

Dirty Water: To purify dirty water, filtering technology can be used such as filtering with zeolite, activated carbon, or by using a Reverse Osmosis systcan

• Number 7

Iron-Containing Water: To purify iron-containing water, you can use precipitation or filtering techniques using sand and activated carbon media.

• Number 8

To purify water that contains germs, there are several ways that can be done, namely by heating Germs in water can be killed by heating the water to a high enough temperature, which is around 70°C - 100°C. However, this method is only effective for killing certain germs.

• Number 9

There are several ways to clear cloudy water, including filtration techniques can be carried out using sand, activated carbon, or ceramic filters.

• Number 10
