  • Wastewater engineers go with the flow

    The efficiency of maintenance work has been improved by water treatment engineers employing Intellisonde monitors in their final effluent. Designed primarily to measure water quality, the Intellisondes also measure flow, and this reading is being used to detect the accumulation of debris that necessitates a maintenance visit. Wastewater treatment efficiency is often measured by the analysis of ...

  • The construction of an engineered bacterium to remove cadmium from wastewater

    The removal of cadmium (Cd) from wastewater before it is released from factories is important for protecting human health. Although some researchers have developed engineered bacteria, the resistance of these engineered bacteria to Cd have not been improved. In this study, two key genes involved in glutathione synthesis (gshA and gshB), a serine acetyltransferase gene (cysE), a Thlaspi ...

  • Uncertainty Analysis in Wastewater Engineering Modeling: Understanding the Limitations

    ABSTRACT Design engineers commonly rely on physical and mathematical approximations or models of real complex phenomena. During the development of these physical or mathematical models, simplifications and assumptions need to be made to develop such tools. It is unrealistic to expect that the modeling process will give an answer that is a perfect match to the real case, and it is, therefore, ...

  • The application of surface engineered silica for the treatment of sugar containing wastewater

    The removal of sucrose and fructose from water at various high concentrations by surface engineered silica (SES) was studied using dissolved sugar in pure water. The results indicate that sugar at concentrations of up to 800 g/L can be removed by SES at a relatively high dose of 250 to 300 g/L. Based on these results, process water from a soft drink filling station which was contaminated by ...

  • Chemical Engineering Magazine: Odor Issues and Solutions for Wastewater Treatment

    Today, there has been a dramatic increase in the number of industrial operations that are located within or near small towns and even large cities. When local residents constantly smell these industrial processes – particularly from wastewater treatment — unhappy neighborhoods are generally the result. In addition, many wastewater facilities can no longer produce odors without facing ...

  • Refinery Wastewater

    A refinery was storing wastewater in several tanks and needed to meet the city discharge limits before they were allowed to dispose of the water. The problem was with soluble sulfides (1,000 ppm in the water) as the discharge was 0.5 ppm. Integrated Engineers was contacted to see if they could create a treatment process to reduce the sulfides to discharge limits. Several large water treatment ...

  • A review of the detection, fate and effects of engineered nanomaterials in wastewater treatment plants

    Engineered nanomaterials (ENMs) are increasingly found in a wide range of products and processes, and consequently increasing loads are expected to reach wastewater treatment plants (WWTPs). To better assess the potential risk of ENMs to the environment via input through WWTP effluents, this review considers ENM detection methods, fate in WWTPs and potential effects on biota exposed to ...

  • Peach Processing Wastewater Treatment

    A major fresh pack operation of peaches and nectarines needed a screening system to remove the labels and peach fuzz from their wash water before it was pumped from the pond for irrigation use. Flow to the pond is a steady flow of 50 gpm, rising to 600 gpm during periodic draining of the peach coolers and washing systems. The water is a combination of wash water, labels and fuzz from the fruit, ...

  • Viltra IWOX systems engineered by DMT - The next standard in small scale wastewater treatment

    Abstract Both technology and environmental awareness drive legislation for wastewater treatment. Now, the leap from 20/30 (BOD: Biological oxygen demand, mg/l / SS: suspended solids, mg/l) to 10/10 or even 5/5 is possible due to a different design approach. For years, the sewage treatment plant market was dominated by systems from (septic) tank suppliers, but now an engineering company ...

  • Efficiency of sugarcane bagasse-based sorbents for oil removal from engine washing wastewater

    This work evaluates the efficiency of sugarcane bagasse-based sorbents in the sorption of oil from engine washing wastewater. The sorbents were obtained from sugarcane bagasse in the natural form (SB-N) and modified with either acetic anhydride (SB-Acet) or 3-aminopropyltriethoxysilane (SB-APTS). The results showed that the sorption capacity of these materials decreased in the following order: ...
