Microalgae Cultivation in Wastewater for Nutrient Removal
Wastewater is the spent or used water containing dissolved or suspended solids such as pollutants and microbes, including nutrients. The wastewater discharged into the water bodies are hazardous to environment and cause various health problems in human beings. Eutrophication is one such major environmental problem caused due to the discharge of nutrient rich wastewater into the nearby water bod...
متن کاملNutrient removal from wastewater by wetland systems
For past so many years wetlands have served functions like providing habitat for aquatic and terrestrial plants and animals, for recreational activities and for treatment of polluted water. Both natural and constructed wetlands gave been used for treatment for wastewater from sewage, septic tanks, agricultural activities, industries, landfills and highways, etc. Treatment of wastewater in a wet...
متن کاملIsolation of microalgae with potential for integrated biomass production and nutrient removal from wastewater
Abstract The present study firstly investigates the variations of microalgae in the constructed wetland. Then one of the potential microalgal species was isolated and cultured in autotrophic and mixotrophic growth to compare the performance on biomass production and to evaluate the ability of wastewater treatment and simultaneous biodiesel production. Scenedesmus sp. was an abundant strain in t...
متن کاملMicroalgae cultivation in wastewater: nutrient removal from anaerobic membrane bioreactor effluent.
This study investigated the removal of nitrogen and phosphorus from the effluent of a submerged anaerobic membrane bioreactor (SAnMBR) by means of a lab-scale photobioreactor in which algae biomass was cultured in a semi-continuous mode for a period of 42 days. Solids retention time was 2 days and a stable pH value in the system was maintained by adding CO(2). Nitrogen and phosphorus concentrat...
متن کاملMethanotrophic bacteria for nutrient removal from wastewater: attached film system
It was hypothesized that nutrient removal from waste water could be achieved by using methane oxidizing bacteria (melhan otrophs). Because methane is inexpensive. it can be used as an energy source to encourage bacterial growth to assimilate nitrogen and phos phorus and other trace elements. This initial feasibility study used syn thetic nutrient mixtures and secondary sewage effluent as fe...
