  • Manufacturer of Water Treatment Chemicals and Water Additives

    Water treatment is a process for treating sewage or modern wastewater and converting it into more acceptable form for a specific end-use. The end utilization of this treated water might be drinking, mechanical water supply, water system, waterway stream support, water diversion or numerous different uses, including being securely returned to nature. Water treatment expels ...

  • Monitoring of Hydrogen Sulfide in Industrial Processes

    Hydrogen sulfide, H2S, is a very poisonous, corrosive, and flammable gas. As such, it needs to be carefully monitored and controlled in industrial processes where it is generated or used. At relatively low concentrations, it has an odour of rotten eggs which effectively works as a warning, but at higher concentrations where it becomes acutely toxic and even lethal, it can no longer be smelled ...

  • 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 ...

  • 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 ...

  • Electrocoagulation in Water Treatment

    Although electrocoagulation (EC) is an evolving technology that has for the past 100 years been effectively applied in industrial water treatment, the paucity of scientific understanding of the complex chemical and physical processes involved as well as the limitations (in terms of size and cost) of the needed power supplies in the past, have curbed large scale applications and hindered progress. ...

  • 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. ...

  • 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 ...

  • The wastewater treatment of the food industry

    The wastewater treatment is a process which is used to recycle the wastewater into an effluent that can be reused again. This treatment helps in removing all the impurities from the water. Many industries are involved in this type of treatment to make use of water and not to waste it. Due to the scarcity of water, this type of water recycle is necessary. Many foods and beverage ...

  • 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 ...

  • What Is Industrial Wastewater Treatment?

    Industrial progress has helped economic and social growth to a large extent, whereas, it has also created the major problem of environmental pollution at the same time as well. Industrial pollution is one of the major concerns of industries and environment protection agencies worldwide. The technical advantages have assisted the industries to reduce water pollution to a certain level. ...

  • Wastewater Treatment for the Mining Industry

    Sustainable wastewater technologies minimize mining’s environmental footprint Mining for some minerals, including coal, has been diminishing due to increased financial, social, and environmental pressures, both in the United States and abroad. At the same time, mining for lithium and other metals — used in energy storage for electric cars, and wind and solar generation — is ...

  • Water treatment technology for produced water

    Large amounts of produced water are generated during oil and gas production. Produced water, as it is known in the oil industry, is briny fluid trapped in the rock of oil reservoirs. The objective of this study was to test produced waters from a Montana USA oilfield using a mobile station to design a plant to cost efficiently treat the produced water for agricultural irrigation. We used combined ...

  • 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 ...
