Algae for its consistent growth requires sufficient amount of nutrients. \u00a0Since waste water already contains nitrogen, carbon and \u00a0phosphorous there is a speculation that the algae growing in waste water might not require any additional nutrients, however, research studies reveal that some amount of nutrient additions might be required. The necessary addition of nutrients also depends on the type of wastewater. Effluent of biological water purification may, for example, require phosphate and trace elements to be added to enable good growth.<\/p>\n
For optimal growth, the culture must be provided with nutrients in adequate amounts (Borowitzka, 1988). These include several macronutrients such as carbon, nitrogen, phosphorus, sulfur, potassium, (for diatoms also silicon) and a number of trace elements like minerals (e.g. Co, Mo, Mn) and vitamins (e.g. Cyanocobalamine, thiamine). Besides quantities, the right proportions among nutrients (e.g. N: P; N: Si) are also important. Basic information on algal nutrition is given by (Kaplan et al., 1986).<\/p>\n
Effluent or other wastewater generally (also) contains carbon in bound form (COD). In some tests, it was found that this organic substance in the algae system is mineralized by bacteria, thus making CO2 available for uptake by the algae.<\/p>\n
The optimal C: N: P ratio required for algal growth is 50:8:1. But the ratio in typical municipal wastewater for C: N: P is 20:8:1. Hence CO2 addition to a wastewater system could enhance algal production.<\/p>\n
