Ancient Indians used seeds of Moringa Olifera tree to de contaminate drinking water. The process involved crushing the seeds and then mixing them with water to remove impurities. Moringa trees also grew well in scanty regions and hence were used by inhabitants in various dry and humid regions of India. Modern Canadian scientist conducted a research, where they found that Moringa seeds effectively kill over 90% bacteria present in the water. Lily roots and Nirmali seeds were also used instead of Moringa. The seed purification method was extensively used in Southern India.
Use of Copper Vessels
The Vedic period was also known for its usage of the right of utensils when eating or drinking. The sages in those times were conscious enough to know the benefits of various kinds of metals and how it could directly contribute to our health.

This was a refrigeration concept in India and prevented sun strokes and all heat related ailments.
Use Filtration Method
Sushruta Samhita is an ancient text written by the most popular doctor and surgeon of ancient India, Sushruta. In it he mentioned that water must be passed through a layer of sand and gravel before consumption. It should then be boiled and cooled completely before drinking it. This process was largely practiced by Indians during that time. it was an effective remedy to clear out suspended materials from the water.
This type of method was used to remove air borne impurities that was present in the water like dry leaves and twigs, dust, coarse earth particles and others. The raw water was passed through a winnowing sieve. The impurities were collected on the sieve and later thrown away, giving you fresh clear water to drink.
In this method a white cotton cloth was used to filter water. Dust, sand, small stones, leaves, dead insects and others were removed by passing the water through the cotton cloth. This method is similar to winnowing and was only used in filtration of large particles present in water. It was mostly used when water was collected from the well. Usually well water was extremely muddy and odorous. Hence Sal wood was burnt and the ash of it was mixed together with the water and passed through the cloth. The ash helped in removal of the odor.
After the introduction of ceramics, ceramic filters took the world by storm. They were made of clay mixed with combustible materials like saw dust, wheat husks or rice husks. They acted as filters and removed harmful bacteria like E Coli. It also acted as a method of storage. Water stored for 16 hours in these ceramic filters were considered ideal for consumption.
As days advanced the above techniques were replaced by chemicals. The most common ones used were chloride and alum. Chlorine released hydrochloric acid in the water, which killed several types of microorganisms. However, this technique lost its popularity in treatment of drinking water, as it could not kill the protozoa and was used only in swimming pools. It is in fact used still today in treating pool water and making it effective for swimming.
