A Study On The Simultaneous Nitrification And Denitrification Process Of A Membrane Aerated Bioreactor Augmented By Biowish Aqua, Gavrielle Orman Oct 2019

A Study On The Simultaneous Nitrification And Denitrification Process Of A Membrane Aerated Bioreactor Augmented By Biowish Aqua, Gavrielle Orman

Master's Theses

Nitrogen pollution is a growing problem that is detrimental to the environment and the economy. Traditional treatment of nitrogen is a multi-stage process, expensive, operationally intensive, and requires large land areas. This research studied the effects of BiOWiSH® Aqua (Aqua), a biological enhancement product, on the simultaneous nitrification and denitrification process in a membrane aerated bioreactor (MABR) to determine if it is a feasible application for wastewater treatment. The MABR used during experimentation was a small-scale batch reactor with a continuous flow of air through a silicone membrane.

The effect of carbon source and concentration on nitrogen removal rates and …


Effect Of Bio-Augmentation Product Biowish® Septic Rescue On The Wastewater Treatment Performance Of Residential Septic Tanks, Kimberly Michelle Lamar Merilles Mar 2019

Effect Of Bio-Augmentation Product Biowish® Septic Rescue On The Wastewater Treatment Performance Of Residential Septic Tanks, Kimberly Michelle Lamar Merilles

Master's Theses

Residential septic systems provide reliable wastewater treatment for over 26 million homes and facilities in the United States, and many more worldwide. When properly maintained, these systems are reliable, low-cost, and long-term treatments for residential wastewater. When neglected, septic systems can fail and lead to health concerns and ecological harm to soil and groundwater contamination through the improperly treated wastewater effluent.

This study tested the effect of the bio-augmentation product BiOWiSH® Septic Rescue of BiOWiSH® Technologies International, Inc. (hereafter referred to as BiOWiSH) on the biological treatment of residential septic tanks. BiOWiSH is meant to act as a bio-augmentation product …
