  • A breath of nothing is decisive: AERZEN Turbo blowers with air bearings provide clear advantages compared to blowers with magnetic bearings

    Aeration tanks for wastewater treatment must be continuously provided with large air volumes. Turbo blowers offer here energy-efficient solutions. AERZEN has developed an amazingly simple method for the fast-rotating Turbo blowers - air bearings. The construction of AERZEN Turbo blowers is quite simple: A blade wheel, aerodynamically optimised and located directly on the motor shaft, rotates in ...

  • 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 ...

  • UV Light Treatment for HVAC Systems

    Ultraviolet (UV) light can be applied to support numerous applications in a broad range of industries. In commercial paint spray booths and label manufacturing plants, UV lamps are used to streamline paint jobs and the printing of logos. Outside of such practices, the light source may also be utilized to eradicate harmful, disease-causing bacteria. Systems that rely on the light’s ability ...

  • 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 ...

  • 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 ...

  • Land Treatment

    Introduction Land Treatment is a full-scale bioremediation technology in which contaminated soils, sediments, or sludges are turned over (i.e., tilled) and allowed to interact with the soil and climate at the site. The waste, soil, climate, and biological activity interact dynamically as a system to degrade, transform, and immobilize waste constitutes. Wastes are periodically tilled to aerate the ...

  • Nitrification processes in scrubbing liquid of an exhaust air treatment system of a large-scale pig housing facility

    The use of multi-staged exhaust air treatment systems is an effective method of substantially reducing the emission of ammonia, dust particles and odorous substances. Wet filter walls are able to absorb large amounts of ammonia when scrubbing fluid containing sulphuric acid is used. In addition, due to their large surface areas and the permanent supply of oxygen and nutrients, wet filter walls ...

  • 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 ...

  • 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 ...

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

    Three technologies that are most commonly used to treat nonhalogenated 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 ...

  • Dissolved air flotation separation for pretreatment of membrane bioreactor in domestic wastewater treatment

    Due to requiring higher water quality standards over time, new technologies are being employed for wastewater treatment. Dissolved air flotation (DAF) and membrane bioreactor (MBR) technologies are widely employed as new technologies in wastewater treatment. DAF is used due to its excellent separation capability of suspended solids as well as oily material. MBR is used because it may provide a ...

  • 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 ...

  • Using Air Strippers for Off-gas Treatment - Case Study

    Two pharmaceutical plants in Puerto Rico used large sequencing batch reactor (SBR) systems to treat their wastewater. The primary treatment was an aerobic bio breakdown of the waste. The were forced to change their treament process because of change in treatment regulations. The new regulations required them to treat off-gas that was coming from the SBRs. They were faced with installing a very ...
