Autotrophs play an important role in remediation of wastewater particularly domestic waste
through it photosynthetic ability. To investigate the role of algae in wastewater treatment algal
samples were collected from polluted water. These samples were used to isolate most dominant
and pollution tolerant algae such as C. vulgaris and S. quadricauda cultures in BBM and used
for the treatment. The domestic wastewater samples used in this study were collected from
sewage wastewater treatment plant Bopodi from Pune city. To study the role of microalgae in
wastewater, the following protocols were used, (i) Wastewater treated with culture of C. vulgaris
and S. quadricauda; and (ii) Wastewater treated without culture of C. vulgaris and S. quadricauda
(Control). Samples were periodically (every 5th day) analyzed for physico-chemical parameters
such as pH, phosphate, nitrate, BOD and COD using standard methods. C. vulgaris shows the
best removal capacity of nitrate and COD while S. quadricauda shows BOD and phosphate
reduction. Present investigation focuses on the bioremediation of wastewater by using micro
algae.

INTRODUCTION

address water quality challenges in the regions.
Bioremediation uses naturally occurring
microorganisms and other aspects of the natural
environment to treat wastewater of its nutrients.
Bioremediation can prove less expensive than
other technologies that are used for cleanup of
hazardous waste (Vidali, 2001).

The world is facing problems with a wide variety
of pollutants and contaminates from various
developmental activities. The population explosion
in the world has resulted in an increase in the
area of polluted water. The concern on the
quantity and quality of waste generated and
discharged into natural water bodies has recently
indicated the need for different strategies to

Algae are universally acknowledged as playing
a very important role in natural water purification
