Ans 1. This method of water purification will be effective only up to a certain extent. The filter may give transparent water but it will still contain lot of contaminants.

 

Ans 2. The collected water can be used for watering plants, gardening, washing vessels and clothes, and for other cleaning purposes. It cannot be used for consumption.

 

Ans 3. Since water is being purified without being wasted, it is apt to call it water conservation. Also, no electricity is being used as it is done in the factories. Therefore, the method also conserves electricity.

Ans 4. This method of water filter cannot be used as it is in factories. However, the same principle is used in factories for purifying water by using motors and electricity.
