ABSTRACT
The disproportional distribution of water sources on earth accompanied by the exacerbation of its quality is one of the most significant factors affecting the growth and development of society. Water is a very important feedstock, resources of which are said to be renewable, but on the other hand limited. Desalination market is driven by a limited drinking water supply of the people, and increasing demand for water, caused by population growth and changes in their style of life. The decrease in water desalination costs caused by the constant technology development is also important. The proper pretreatment of raw water is the key factor determining either success or failure of a desalination process. It is especially important in the case of process performance with reverse osmosis (RO) use, but also in the case of other desalination techniques.
