Waste Water Treatment Using Micro-Algae - A review Paper
ثبت نشده
چکیده
The present study illustrates the efficiency of microalgae based treatment system. Treatment of wastewater with Microalgae based system have the ability to remove nutrients (Nitrogen, Phosphorus and other nutrients), heavy metals, toxic substances (both organic and inorganic), BOD, COD and other impurities present in the wastewater by using the sunlight, CO2, and impurities like nutrients present in the wastewater. The microalgae also have the ability to fix the excess Carbon dioxide present in the environment and release the oxygen and solve the problem of Global warming. According to the various study, the nutrients removal efficiency of microalgae based wastewater treatment system is very high as it removes 78-99% of Nitrogen and Phosphorus. The treatment system also succeeds to remove 40-65% of COD, BOD and other impurities present in wastewater. The microalgae treatment system is economical, green, and environmental friendly option of wastewater treatment. Keywords—Microalgae, Nutrient removal, wastewater,

Utilization of Microalgae for Integrated Biomass Production and Phycoremediation of Wastewater
Increasing population and Industrialization are key pollutant contributors in water bodies. These wastes are highly hazardous for humansand ecosystem and require a comprehensive, effective treatment before discharge into water bodies. Over the years, many up gradations have been introduced in traditional water treatment methods which were expensive and ineffective especially for removal of heav...

متن کاملWaste Stabilization Ponds for Waste Water Treatment, Anaerobic Pond
Waste stabilization ponds (WSP) have been used world-wide over the last 50 years for municipal and industrial wastewater. The waste water treatment system has been accepted and used to change the physical, chemical, or biological character of the waste. This article presents the characteristics, parameters, and examples of the waste stabilization ponds all over the world. This work was based on...
متن کاملThe removal of thermo-tolerant coliform bacteria by immobilized waste stabilization pond algae.
This study investigated the potential of laboratory- scale columns of immobilized micro-algae to disinfect effluents using thermo-tolerant coliforms (TTC) as a model system. Cells of a Chlorella species isolated from a waste stabilization pond complex in Northeast Brazil were immobilized in calcium alginate, packed into glass columns and incubated in contact with TTC suspensions for up to 24 ho...
متن کاملThe removal of uranium from mining waste water using algal/microbial biomass.
We describe a three step process for the removal of uranium (U) from dilute waste waters. Step one involves the sequestration of U on, in, and around aquatic plants such as algae. Cell wall ligands efficiently remove U(VI) from waste water. Growing algae continuously renew the cellular surface area. Step 2 is the removal of U-algal particulates from the water column to the sediments. Step 3 inv...
