Biological desalination of saline and seawater using Dunaliella salina and Cholorella vulgaris algae

The water crisis is one of the major environmental challenges. Due to the problem of cheaper and faster desalination of seawater than seawater, in order to supply water, it has become increasingly important. Desalination using biological methods involves the use of different species of plants, microorganisms, algae or a combination of them, which can be effective in reducing water salinity. The aim of this study was to investigate the desalination of saline waters using seaweed. The present study was conducted to investigate the desalination of brine waters using seaweed. The present study was performed as a factorial study in a completely randomized design. The two-way ANOVA analysis of variance was performed with two main treatments including two types of algae (Dunaliella salina and Cholorella vulgaris) and two sub-treatments including 2 salinity levels (50 and 70 milliseconds per centimeter). The experiment was performed under controlled laboratory conditions and during the incubation period, electrical conductivity was measured daily. The results showed that the uptake of chlorine, sodium and bicarbonate was significantly different in Dunaliella salina and Cholorella vulgaris algae. Decreased by 3 mmHg Based on the research results, it seems that the reduction of salt absorption in algae using salt is in algal metabolism and their growth and reproduction.
