To treat municipal wastewater effected from different sources of product, toilet, industry in most cases use microorganisms which requires a constant supply of oxygen, which is expensive and requires intense operations, energy input, manpower, and expertise. So, to reduce this much effort we can use to treat Growing microalgae in the ponds and tanks where the treatment is carried out is a good alternative solution to this problem since algal growth and photosynthesis will release substantial amounts of oxygen. At the same time the microalgae will remove nutrients (nitrogen and phosphorus). Microalgae are a diverse range of single celled primary producers and are found practically everywhere where there is light and humidity at least at some time of the year. The most important groups of microalgae in terms of abundance are green algae (Chlorophyceae), diatoms (Bacillariophyceae), blue-green algae (Cyanophycean) and golden algae (Cryophyte). The total estimated number of algae species are 200 000 to 800 000, of which 35 000 are described in literature. Microalgae can be identified depending up on their phylum, color, shape presence of flagella or absence, motility or not, typical morphology and the others of biological aspects such as chlorophyll type and organic content in technological way. To sample and transport to laboratory first know the chemistry of the fresh water sampled, consider factors to sample, put plot on each sampling point, mention the factors looking for and answer why? Question keep sampling material neat, sample without contaminant in proper manner and transport to laboratory is a good way to day. All most factors encountered during microalgae growth are: Contaminations, PH (Acidity or Alkalinity), temperature, total dissolved solid, Conductivity, salinity, aeration etc.
