Abstract

Nutrient enrichment or eutrophication of aquatic ecosystems can cause an increase in algae and aquatic plants, loss of component species, and loss of ecosystem function. For these reasons, numerous studies were focused on nitrogen and phosphorus removal from wastewater streams. Most of these studies were based on biological processes and different combinations of anaerobic, aerobic, and anoxic zones such as Bardenpho, A2O, UCT, and their modifications. Hence phosphate recovery from sewage is in synergy with reducing other environmental impacts and making it a long term economic resource. The aim of the novel treatment process is to highlight on studies investigated for the nutrient removal performance using Chorella-vulgaris at different nitrogen and phosphorus concentrations. The effect of ammonia nitrogen and phosphorus concentration on removal of these nutrients from synthetic wastewater by algae Chorella-vulgaris in batch cultivation have been investigated in this study and kinetic coefficients were determined. It is observed that an effluent may contain specific nutrients valuable for recovery and this observation may lead to the idea or understanding of treating an effluent from industrial source as a useful resource instead of the general idea of treating the effluent as waste products, and in the same process losing money in terms of expenses on chemicals and energy. Treatment and discharge of effluents into the receiving streams should not be an issue that will be considered as usual because there are specified standards required by the legislation, in terms of the quality and characteristic of the effluent before it is discharged into the waterways.
