The Biodiversity of Algae and Physio-Chemical Parameters of the Sewage Treatment Plant and its Canal Length, Located in Sana’a City, Yemen

Abstract

This study of the biodiversity of algae is the first interest in Yemen as a future vision for sustainable alternative solutions using sustainable resources as a sewage treatment plant with its channel length in Sana’a city, Yemen. The study aimed to screen the family of algal genera. A total of 13 samples were selected with GPS, and 100 ml of water was filled up in a plastic container and directly read as wet preparation under light microscope, identified in accordance with algae standard methods in three replicates with determination of temperature, pH, and total dissolved salts. The results showed that microalgae were conducted higher than others’ algae under the mean value of temperature 28˚C and neutral pH and high total dissolved salt, indicating the economical role of algae presence and waste treating by algae in despite of there was no physical or chemical processing treatment done, and the microalgae genus was found as Chlorella vulgaries with a ratio of 100%, followed by Chlamedomonas reinhardtii and Kirchneriella lunaries with a ratio of 76.72%, and the less found genus of filamentous algae was Nostoc sp., Oscillatoria phucus, Ulotrix micrasterias, Dingoflagellate ceratium, and Desmedium with a ratio of 7.69% for each, and finally, diatoms were found along the stages. The variant of the algal family will be used soon for many applications next studies.
