wastewater contaminant Applications

  • Water Contamination Detection

    Security of water assets is becoming an increasingly major issue that demands immediate and robust alarms for potential contamination. In addition to this, natural growth of algae is a common problem for water asset managers, the results of which can increase maintenance costs of water processing plants as well as directly effecting water taste. The CTG FastGuard fast repetition rate fluorometer analyses information on the physiological state of the algae it monitors within an in-line flow system. A number of key parameters are monitored and analysed by the on-board embedded software, which instantly initiates both an audible and visual alarm on detection of a contaminant within the water system. The FastGuard is a robust low maintenance system which avoids false positives often provided by other contamination detection systems.

    Industrial solutions for cooling water contamination

    Problem: Large quantities of water are used for cooling in industrial manufacturing. To prevent scaling, corrosion and biofilm in the cooling system, inhibitors and biocides are regularity dosed. Make-up water is continuously added to the system to balance the loss of water from evaporation. As water is added, the concentration of chemicals is diluted and the quality of water changes.

  • Plating rinse wastewater solution

    Plating rinse wastewater is one of the most common applications for ENCON Wastewater Evaporators. Wastewater from plating rinse tends to be rather corrosive. The chemistries used in the plating process can include a wide range of acids such as nitric acid, chromic acid, hydrochloric acid, sulfuric acid, hydrofluoric acid, as well as other non-acid chemistries like ammonium bifluoride and nickel sulfamate. Typically, the waste stream has a transparent, relatively clean look because they are dilute and the contaminants are in solution.

  • Air scrubber wastewater solution

    Air Scrubbers strip out contaminants from exhaust stacks typically by trickling a stream of salt solution through a bed of media to extract contaminants by putting them into solution. The salts found in these solutions are typically sulfates, chlorides, and carbonates. Air Scrubber wastewater tends to have high total dissolved solids (TDS) or salts. Air Scrubber Wastewater cannot be simply flushed down the drain. Many companies choose to avoid the headaches of labor-intensive wastewater treatment technologies such as chemical treatment or filtration and simply pay to haul the wastewater. This however, can become quite expensive.

  • Filtration systems & solutions for wastewater treatment industry

    The removal of contaminants from untreated water has become a leading issue, due to environmental concerns and the threat of future water shortage. An effective purification process is necessary to eliminate organic, chemical or other debris to meet stringent regulations for drinking water, as well as for the chemical, industrial, pharmaceutical and science markets.

  • Air control for wastewater treatment aeration

    Aeration Process Introduction: Waste Water Treatment removes impurities and contaminants from a com¬munity`s sewage utilizing a number of different processes and a variety of equipment. One of the processes is the use of surface aerated basins that use aerobic micro-organisms to remove 80 to 90% of organic matter in waste water. Oxygen concentration in the water basins is a critical factor to promote the optimum micro-organism growth rate needed to treat the water in the shortest amount of time. As a result, large compressors are used to force air through hundreds of air diffusion filters at the bottom of the aeration basins, providing a constant 24/7 supply of oxygen to the micro-organisms in the water.

  • Wastewater treatment for the biofuels

    In these companies, the water to be treated can vary depending on the technology used and on the raw materials. These effluents usually contain high concentrations of contaminants, especially those coming from esterification processes.

  • Solutions for the aerobic bioremediation

    BioSolve Pinkwater is used to accelerate natural bioremediation of contaminated soil either on site through surface application or on land farms through application to biopiles. When Pinkwater solution is sprayed onto and aggressively mixed into contaminated soil, hydrocarbons come in contact with the strongly “lipophilic” (oil loving) surfactant. Mimicking the process by which bacteria make hydrocarbons digestible, the surfactants “solubilize” contaminates, pulling them into an aqueous phase. This greatly enhances “bioavailability” for naturally occurring hydrocarbon degrader bacteria. Bacteria are able to more rapidly consume the contaminating oil/fuel, thereby dramatically accelerating the biodegradation process.

  • Biological wastewater processes for mining

    The mining industry has the potential to use large amounts of wastewater in its operations. Often times these waste streams contain contaminants that require treatment before the water can be re-used or discharged. Biowater has successfully installed highly efficient biofilm treatment processes including our complete mix fixed film (CMFF®) system to remove BOD/COD, and nitrogen from mining waste streams. Biowater’s technologies, such as our CFIC® process, can produce effluent water quality that is acceptable for re-use, reducing the stress on ecosystems in water stressed areas.

    Wastewater Treatment

    Many industrial and pharmaceutical processes generate wastewater with volatile contaminants that increase the COD and BOD to a point where discharging to municipal wastewater is very costly or not an option. These contaminants can be removed from the water by distillation, substantially lowering the disposal cost, and, in many cases, the removed components can be further purified and reused in the process. MEGTEC offers the following solutions to remove the volatile contaminants and make wastewater suitable for discharge to most municipal wastewater treatment plants: Stripping columns using direct steam or a reboiler Distillation columns using indirect steam heat sources Our technologies have been applied to a range of processes including wastewater treatment from industries such as Pharmaceutical, Semiconductor, Chemical and Petrochemical.

  • Wastewater treatment for the cosmetics industry

    The cosmetics industry accrues many kinds of wastewater. The challenge for wastewater treatment is that product lots are often changing, thus changing the composition of the wastewater. Switching to a new product lot in particular, produces large amounts of wastewater that are contaminated by surfactants, dye, oils and emulsions and high COD concentrations. In addition, wastewaters foam excessively at times.

  • Protecting of Drinking Water Infrastructure

    Water abstraction points may be affected by spills from farms or factories, and deliberate contamination. Early warning monitoring systems are required to alert operators to these contaminants and to changes in key water quality parameters. A timely response is necessary to prevent contamination and disruption of the public water supply.

    Chelsea Technologies Group has developed FastGuard to observe the natural trends in water quality parameters and rapidly detect and report anomalies.

    FastGuard is ideally suited for early detection of contamination events. It gives prompt reporting and asessment of the threat and has high sensitivity with minimal false alarm rate.
