  • 10 Reasons why you should continuously monitor low temperature and liquid chemical sterilants for worker safety

    1. Sterilant chemicals are highly toxic Low temperature and liquid chemical sterilants are designed to kill all microorganisms including resistant spores and if they were not toxic, they would not be effective in sufficiently high concentration to destroy all microbial life including the chemically resistant sporicidal forms of certain ...

  • MSW Management: Safely Countering the Rise of Landfill Odors

    One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints. In fact, compared to other industrial applications such as wastewater treatment and asphalt ...

  • Integrated process control for recirculating cooling water treatment in the coal chemical industry

    This work focused on the integrated process of the recirculating cooling water (RCW) treatment to achieve approximate zero emission in the coal chemical industry. The benefits of fractional and comprehensive RCW treatment were quantified and qualified by using a water and mass balance approach. Limits of cycle of concentrations and some encountered bottlenecks were used to ascertain set target ...

  • Water Conservation: A Vital Consideration in Industrial Water Treatment

    Abstract Groundwater shortages, EPA regulations, aquifer pollution, and increasing restrictions on the use of chemicals in open recirculating cooling & process water systems have driven the need for alternative technologies in this sector of industrial water treatment. The VRTX Technology is a mechanical water treatment system designed to address this alternative need in cooling and ...


  • Field Pilot Study of a Chemical Oxidation Process for Treatment of Industrial Waste Leachate

    Remediation efforts are ongoing at the Avtex Fibers Superfund Site in Front Royal, Virginia. As part of the future remediation of several surface impoundments used for viscose waste disposal during plant operation, it may be necessary to extract contaminated leachate and groundwater for ex-situ treatment and discharge to the Shenandoah River. This waste stream contains varying concentrations of ...

  • On-site 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 ...

  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of. Wastewater treatment is a multi-stage process to renew wastewater before it is discharged to the municipal sewer system. The goal is tio reduce or remove organic ...

  • Treatment of Water-Wash Paintbooth Effluents in the Automotive Industry

    During the coating process of car bodies in water-wash spray booth, around 40% of the sprayed paint does not reach the support; these paint particles sprayed into the air are called “overspray”. By using a dawn-draft positive air pressure coming from the ceiling of the cabin, the polluted air is forced vertically downward toward a grating on the floor under which a constant stream of water is ...

  • Chemical monitoring strategy for the assessment of advanced water treatment plant performance

    A pilot-scale plant was employed to validate the performance of a proposed full-scale advanced water treatment plant (AWTP) in Sydney, Australia. The primary aim of this study was to develop a chemical monitoring program that can demonstrate proper plant operation resulting in the removal of priority chemical constituents in the product water. The feed water quality to the pilot plant was ...

  • Wastewater pre-treatment in a confectionery industry

    Description of the plant In a first step, wastewater accruing from the production of marzipane is cleaned by a screen. As flow and load to the plant are highly variable depending on the production process an aerated mixing and balancing reactor has been installed to equalise flow and load before final chemical pre-treatment. After adding of chemicals for precipitation and flocculation ...

  • Chemical wastewater treatment applying a membrane bioreactor (MBR)

    IntroductionAt the current time Membrane Bioreactors (MBR) are the primary focus of wastewater treatment technologies. MBR is a combination of biological activated sludge process for the removal of nutrients and a membrane filtration for separation of biomass and treated water. In industrial wastewater treatment MBRs have proven to be a particularly reliable technique [Cornel et al., 2006]. The ...

  • Water treatment in Brazil

    The challenge Many factories in Brazil do not dispose their sewerage in a professional way. Only big enterprises use facilities to treat their industrial waste water, whereas numerous small and medium-sized enterprises convey their sewerage flow into rivers and brooks or pit drainages. This results in a significant environmental burden and endangers the health of the population. ...
