Removal Methods Assessment Through Reduction Algae Count in Uncovered Water Tank

Reduction of water and energy requirement of algae cultivation using an algae biofilm photobioreactor.

This paper reports the construction and performance of an algae biofilm photobioreactor that offers a significant reduction of the energy and water requirements of cultivation. The green alga Botryococcus braunii was cultivated as a biofilm. The system achieved a direct biomass harvest concentration of 96.4 kg/m(3) with a total lipid content 26.8% by dry weight and a productivity of 0.71 g/m(2)...

Rainfall changes affect the algae dominance in tank bromeliad ecosystems

Climate change and biodiversity loss have been reported as major disturbances in the biosphere which can trigger changes in the structure and functioning of natural ecosystems. Nonetheless, empirical studies demonstrating how both factors interact to affect shifts in aquatic ecosystems are still unexplored. Here, we experimentally test how changes in rainfall distribution and litter diversity a...

Methods of Nickel Removal from Valerian Irrigating Waste Water

Industrial development and extensive use of heavy metals have led to the problem of environmental pollution. Nickel compounds are toxic to plants and have detrimental effects on their growth. Valerian is a plant used in herbal medicine. Considering the hazards of nickel, various methods have been developed to remove this contaminant from herbs irrigation wastewater, including the common chemica...

Algae flocculation in reservoir water.

Removal of algae in the reservoir water was studied by electroflocculation using a bipolar cell with aluminum electrodes and flocculation by treatment with commercial alum. Comparison of both the methods is discussed.
