decantation. 3. Sewage disposal: Sewage water contains particles of dirt‚ mud etc. which are colloidal in nature and carry some electrical charge. These particles may be removed by using the phenomenon of electrophoresis. The sewage water is passed through a tunnel fitted with metallic electrodes and maintained at a high potential difference. The colloidal particles present in the sewage water migrate to the oppositely charged electrodes and get coagulated. This solves the problem of sewage disposal. Moreover

Although it is a global disease‚ it is most common in developing countries where “nearly 33% of people [in these regions] have had [Giardiasis]” (Parasites - Giardia). These countries possess inadequate sewage treatment‚ water scarcity‚ and overpopulation‚ which all contribute to the expansion of Giardiasis. A majority of pathogenic microbes are linked to several species such as parasitic worms‚

sources of the pollution. Water pollution “Water pollution occurs when a body of water is affected‚ in a bad way‚ by the addition of large amounts of a material. That material might be oil‚ garbage‚ animal wastes‚ fertilisers and other chemicals‚ sewage or litter.” When water can’t perform its basic function‚ we say that it is contaminated.

Many liquid products (petroleum products) are stored in metal and steel tubes underground. Other sewage systems run in underground tubes. Overtime‚ they rust and begin to leak. If that happens‚ they contaminate the soils and the liquids in them end up in many nearby water bodies. Atmospheric Atmospheric deposition is the pollution of water bodies
