Cultivation of Algae Polyculture in Municipal Wastewater with CO2 Supply

Cultivation of green algae Chlorella sp. in different wastewaters from municipal wastewater treatment plant.

The objective of this study was to evaluate the growth of green algae Chlorella sp. on wastewaters sampled from four different points of the treatment process flow of a local municipal wastewater treatment plant (MWTP) and how well the algal growth removed nitrogen, phosphorus, chemical oxygen demand (COD), and metal ions from the wastewaters. The four wastewaters were wastewater before primary...

Municipal Wastewater Irrigation for Rice Cultivation

In scene of worrisome water shortage, municipal wastewater has been gradually accepted as an alternative water resource containing important nutrients for irrigation. Rice cul‐ tivation, which is one of the main crops feeding global population and requires plenty of water for its effective growth, has been often irrigated by municipal wastewater in many countries. While irrigation of municipal ...

Phosphate and nitrate removal from municipal wastewater by algae Scenedesmus obliquus cultivation and production of algal biomass

Nitrate and phosphate are abundant in urban wastewater. We evaluated the efficiency of nitrate and phosphate removal from wastewater by Scenedesmus obliquus and its use as a medium for Scenedesmus obliquus. Samples were collected from the effluent of central wastewater treatment in Gorgan. This experiment was done by 3 treatments and 6 replications that effluent with 100%, 50% and 0% were dilut...

Outdoor Cultivation of the Biodiesel Promising Microalga Scenedesmus obliquus in Municipal Wastewater: A Case Study

Despite the promising research findings on microalgae as a feedstock for biodiesel, reduction of its production cost is still a challenge. One possible solution to overcome this problem is outdoor biomass production using wastewater as a growth medium. The present study aimed to evaluate the climate key parameters for Scenedesmus obliquus outdoor biomass production during different seasons, as ...
