wastewater evaporation Applications

  • Evaporators technology for power industry

    EVALED evaporators treat or minimize wastewater from the Power Generation Industry. Flue gas desulfurization effluents require different kinds of treatments depending on the type of fuel, water sources, and environmental regulations.

  • Using evaporation to dewater Reverse Osmosis reject waste streams

    Reverse Osmosis (RO) technology has been used for years in various industries to separate dissolved solids from water by forcing the water through a semi-permeable membrane. RO is also commonly used to purify drinking water and desalinate seawater to yield potable water. The water and other molecules with lower molecular weight (specific weight of molecules allowed to pass through is dependent on the selected membrane) pass through the micropores in the membrane, yielding a purified water stream called the permeate. Larger molecules are retained by the membrane as well as a portion of the water that does not pass through the membrane. This concentrated stream is called the concentrate or RO reject.

  • Evaporators technology for health care industry

    In a cutting-edge sector, such as Pharma & Cosmetics production, the needs related to wastewater can be summarized as optimization of the whole water cycle management, controlling the costs and respecting the environment. Within the Health Care industry, water is commonly used in liquid, either as an ingredient in many formulations and also as a cleaning agent. The wastewater coming from these processes can offer opportunities for matter recovery and water reuse.

  • Evaporators technology for oil & gas industry

    The oil & gas industry faces water and wastewater treatment specific challenges. EVALED evaporators represent an effective solution for both downstream (onshore and offshore) and upstream plants, allowing ZLD (Zero Liquid Discharge).

  • Evaporators technology for mechanical & surface treatment industry

    Market segments such as automotive, aviation, furniture, appliance involve: mechanical treatments and surface treatments that require large quantity of water and produce highly pollutant wastewater that cannot be discharged directly and contribute to increase company’s running costs.

  • Ink, Paint, and Glue wastewater solution

    Ink, Paint, and Glue wastewaters are some of the toughest wastewaters to deal with due to their tendency to coat functional components of the wastewater treatment equipment. This type of wastewater is typically treated in the ENCON Drum Evaporator. Qualification of the waste stream for the Drum Evaporator is performed via a bench scale test in the ENCON laboratory.

  • Parts cleaning wastewater solution

    Parts cleaning wastewater is a common application for ENCON Wastewater Evaporators. Parts cleaning is almost entirely water-based since the Montreal Protocol forced companies to abandon chlorinated fluorocarbons (CFC’s) and solvent degreasers. The wastewater is generally brownish gray and translucent with a soapy appearance. It may have trace settled solids and floating oil.

  • 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.

  • Metal finishing wastewater solution

    Metal finishing wastewater is a common application for ENCON Wastewater Evaporators. There are many types of wastewater generated in metal finishing. These include vibratory / tumbling wastewater, stamping wastewater, die casting wastewater and polishing wastewater. Metal Finishing 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.

  • Spent coolant wastewater solution

    Waste coolant or spent coolant wastewater is one of the more common applications for ENCON Wastewater Evaporators. The most common type of coolant is made up of water-soluble oils, but water-soluble synthetics or semi- synthetics are also used. The coolants are used to cool the tool and part to minimize overheating during machining and grinding applications. The coolant is collected in sumps and continuously recirculated. In time, the coolants break down and become less effective. The coolants, now spent, must be disposed of.

    Wastewater Treatment for the Bioenergy Industry

    The waste (water) streams from the production of (bio) ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds. 

    The effluent streams produced by the different production processes are influences by a great number of parameters such as, process design, milling process, type of raw material, etc. This requires special attention in the design of the treatment plant for this type of industry. 

    Typical streams from these industries that can be treated are, whole stillage, thin stillage, spent wash, vinasse and condensate from evaporator. The Upflow Anaerobic Sludge Blanket (UASB) process and the External Circulation Sludge Bed (ECSB) process from HydroThane are worldwide proven processes for the treatment of this type of waste water.

    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.

  • Environmental technology for droplet seperation industry

    As component of the gas scrubbing plants or as single apparatus Körting swirl droplet separators for seperating droplets and recondensates make an essential contribution towards the observation of emission codes and therefore towards the protection of the environment. They are used in gas scrubbing and vacuum plants, for condensate separation in chimney stacks, in evaporating plants as well as for the separation of difficult products (e. g. those with a tendency to polymerisation).
