Case study - Sludge digestion/thickening optimizes treatment
Overview: Big Park Domestic Wastewater Improvements District in Arizona had constructed a new 500,000 gallonsper day biological wastewater treatment system in 1997. As time passed, the aging plant was unable tokeep up with increasing demands. Challenge: In 2012, the District started working with Sunrise Engineering to find a solution that would work in theirexisting plant. Sunrise Engineering partnered with Aeration Industries International to upgrade theequalization basin, as well as the sludge digester/thicken...
Strategies for the reduction of Legionella in biological treatment systems
A community-wide outbreak of Legionnaire's disease occurred in Warstein, Germany, in August 2013. The epidemic strain, Legionella pneumophila Serogruppe 1, was isolated from an industrial wastewater stream entering the municipal wastewater treatment plant (WWTP) in Wartein, the WWTP itself, the river Wäster and air/water samples from an industrial cooling system 3 km downstream of the WWTP. The present study investigated the effect of physical–chemical disinfection methods on the reduction of the concentration of...
Case study - Amine tail gas treatment
COVERING YOUR TAIL GASThe discovery of new shale formations throughout the world and the development of new drilling technologies have increased natural gas production and prompted government agencies to instigate tighter air-pollutioncontrol regulations on processing operations. Unfortunately, meeting environmental regulations is not a profit-generating endeavor. Simply put, the time and money spent on protecting air, water and land does not help midstream companies produce more natural gas to ensure the...
Treatment of hydraulic fracturing wastewater by wet air oxidation
Wastewater produced by hydraulic fracturing for oil and gas production is characterized by high salinity and high chemical oxygen demand (COD). We applied a combination of flocculation and wet air oxidation technology to optimize the reduction of COD in the treatment of hydraulic fracturing wastewater. The experiments used different values of flocculant, coagulant, and oxidizing agent added to the wastewater, as well as different reaction times and treatment temperatures. The use of flocculants for the pretreatment...
Ozone in Cooling Water Treatment
When commercial ozone generators were first introduced for cooling water treatment, they were marketed as a stand-alone treatment, a cure-all or panacea. We now know this is not the case. Because there have been many misconceptions regarding ozone, this article is intended to review the basics of ozone, its true capabilities and limitations, and its potential benefits in cooling water treatment applications.What is Ozone?Ozone (O3) is formed by combining three atoms of oxygen. The air we breathe contains two...
