  • Air systems at a food storage warehouse

    This is a treatment of air systems at a warehouse that stores and redistributes food for 7-Eleven. The customer observed a reduction in electricity bills. However, what was more impressive and valuable for the customer is that the space cooled faster because the air was colder (but not ice cold!). This colder air meant the warehouse could process more food in a day. That resulted in increased ...

  • The development and application of the hybrid centrifugal - dissolved air flotation system for wastewater treatment

    Abstract Solid/liquid separations are integral part of any wastewater treatment system. Particles heavier than water are commonly separated in sedimentation clarifiers. On the other hand, particles with densities lower than that of water are most often separated with flotation systems. This manuscript describes the development of hybrid centrifugal - dissolved air flotation system. The ...

  • Robust systems for optimal treatment - Case Study

    Big Park Domestic Wastewater Improvement District in Arizona had constructed a new 500,000 gallons per day biological wastewater treatment system in 1997. As time passed, the aging plant was unable to keep up with increasing demands. Challenges In 2012, the District started working with Sunrise Engineering to find a solution that would work in their existing plant. Sunrise ...

  • The development and application of centrifugal flotation systems in wastewater treatment

    Flotation as a wastewater treatment technique is designed to remove all particles generally encountered as very fine emulsions, suspended solids, and colloids from wastewater. Historically, Dissolved Air Flotation (DAF) has been used to achieve this removal. More recently, other flotation techniques such as induced air, electro, cavitational, and Centrifugal Flotation Systems (CFS) have been ...

  • H2S Oxidation System for Water Treatment Facilities

    A new water treatment facility in the town of Jupiter, Florida, was causing a serious odor problem. H2S removed from the purified water was being released into the atmosphere. Complaints about the odor came from the residences and businesses downwind of the treatment plant. A turnkey LO-CAT® Hydrogen Sulfide Oxidation System designed to process 30,000 CFM of air containing 250 ppm of H2S ...

  • 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. ...

  • Industrial Wastewater Treatment: Priority pollutant behaviour in on-site treatment systems for industrial wastewaters

    The majority of wastewaters deriving from the chemical industry consist of aqueous discharges produced during the physico-chemical processing of synthetic mixtures involving operations such as filtration, centrifugation, extraction and/or distillation. The wastewater streams, referred to as ‘process waters’ can include mother liquors, washing waters from the purification of products, ...

  • Biofiltration Treatment of α-Pinene

    This paper provides an overview of air biofiltration with experimental data on the performance of a synthetic media biofilter system. It is shown that use of high surface area per unit volume structured media results in higher contaminant treatment rates per unit biofilter volume. It is shown that use of specially designed synthetic media allows effective control of biomass buildup by continuous ...

  • Waste Water Batch Treatment System

    Industrial Wastewater Treatment Batch Treatment Systems (BTS) are intended for lower daily volumes of wastewater typically less than 10,000 gallons per day and designed to “batch” treat wastewater from start to finish at one time. In a batch treatment system, a volume of wastewater is gathered, treated by chemical / physical / biological means, and discharged. Storage ...

  • Performance of air-cathode stacked microbial fuel cells systems for wastewater treatment and electricity production

    Two different air-cathode stacked microbial fuel cell (MFC) configurations were evaluated under continuous flow during the treatment of municipal wastewater and electricity production at a hydraulic retention time (HRT) of 3, 1, and 0.5 d. Stacked MFC 1 was formed by 20 individual air-cathode MFC units. The second stacked MFC (stacked MFC 2) consisted of 40 air-cathode MFC units placed in a ...

  • Common Treatment Technologies for Halogenated VOCs in Air Emissions/ Off-Gases

    Three technologies that are most commonly used to treat halogenated VOCs in air emissions/off-gases are carbon adsorption, catalytic oxidation, and thermal oxidation. Carbon adsorption is a remediation technology in which pollutants are removed from air by physical adsorption onto the carbon grain. Carbon is 'activated' for this purpose by processing the carbon to create porous particles with a ...

  • Characterization of microbial communities in exhaust air treatment systems of large-scale pig housing facilities

    Exhaust air treatment has gained importance as an essential factor in intensive livestock areas due to the rising emissions in the environment. Wet filter walls of multi-stage exhaust air treatment systems precipitate gaseous ammonia and dust particles from exhaust air in washing water. Microbial communities in the biomass developed in the washing water of five large-scale exhaust air treatment ...
