Salinization of Water

Salinization of water is the dissolved salt content or simply the saltiness of the water. This is a general term which is used to mention the various salts present in the water like calcium sulfates, magnesium and sodium chloride. In the ocean, the scientific term for saltiness is salinity. The salinity in oceans is expressed as parts per thousand, not in percent. Read on to know more about the

Salinization of Water – An Overview

Before 1978, the salinity levels in ocean were described in percentages although oceanographers redefined the term of salinity. It is now known as

Practical salinity Scale (PSS)

. This is the conductivity ratio of sample sea water to a standard potassium chloride solution (KCl). One of the main indicators of

world’s ocean circulation

is the degree of salinity present in oceans. The salinity density of water changes due to temperature change as well as salinity change.

The salinity is an important ecological factor, which majorly influences the aquatic organisms living in the water. Also, the salinization of water influences the types of plants or fauna growing under submerged water bodies or getting water from a land (groundwater).

Halophytes

are the plants which are adapted to saline conditions. Organisms which can survive in extreme saline conditions are called

extremophiles

, specifically known as

halophiles

. Organisms which can survive easily in a range of salinities are known as euryhalines.

It is very expensive to remove or eliminate salt from water. Also, salt content is one of the main factors in water use like water potability. The salinity of ocean water is removed by using the process of

reverse osmosis

. Although, the reverse osmosis method is a very expensive method. Salinization of water determines whether the water is fit for drinking or not. Hence, it is a very important factor.
