2.by using cloth

3.by using sand

Answer 2

Answer:

Traditional Methods Used for Water Filtration

Winnowing

Through cloth

Clay vessels

Clarification and filtration through plant material

Jempeng stone filter method

Horizontal flow coarse media filter

Upflow gravel filter

Two-stage filter

Upflow/downflow filter

Filtration done in clay vessel: The technique consists of pouring water into clay vessel having a suitable pore size. The water settles down in the clay vessel and passes through the pores of the clay. The purified water collects in a jar placed at the bottom of the clay vessel.

Filtration done through cloth: This is another common filtration method used in the early years. The filtration process removes impurities such as debris, insects, dust particles and other suspended elements. Water passes through a thin white cloth, which removes impurities present in water.

Filtration done through Winnowing Sieve: The filtration process removes coarse particles and other physical impurities present in water. Raw water passes through a winnowing sieve, which filters all the impurities, thereby collecting fresh water, which is safe for drinking.

modern Methods Used for Water Filtration

Boiling

Boiling water is the cheapest and safest method of water purification. Water sources and or channels of distribution may render your water unsafe. For example, parasites and germs are things you may not see by bare eyes, but their effects can be life threatening.

Distillation

Distillation is a water purification method that utilizes heat to collect pure water in the form of vapor. This method is effective by the scientific fact that water has a lower boiling point than other contaminants and disease-causing elements found in water. Water is subjected to a heat source until it attains its boiling point. It is then left at the boiling point until it vaporizes. This vapor is directed into a condenser to cool. Upon cooling, vapor is reversed into liquid water that is clean and safe for drinking. Other substances that have a higher boiling point are left as sediments in the container.

Chlorination

Chlorine is a powerful chemical that has been in use for many years to treat water for home consumption. Chlorine is an effective water purification method that kills germs, parasites and other disease-causing organisms found in ground or tap water. Water can be purified using chlorine tablets or liquid chlorine.
