Industrial Waste Water Treatment Equipment: Evaporation When considering what industrial waste water treatment equipment to purchase, evaporation is often the first step to consider. Caloris pre-engineered Compact Evaporators were designed with wastewater solutions in mind. Employing various evaporation technologies and available in a wide array of configurations and sizes, they can tackle virtually any industrial wastewater challenge. CALORIS CONCENTRIX® MVR CALORIS CUBIX® CALORIS FLEXMODE® CALORIS AGILIX™ Mobile Evaporator Of course, Caloris also can design a custom evaporation system to suit your unique needs as well. Industrial Waste Water Treatment Equipment: Membrane Filtration While evaporation is often thought of first for dealing with waste water, membrane filtration could be a crucial first step in the process. A CALORIS MEMBRANE system can concentrate your waste stream prior to the evaporation step to maximize overall efficiency.

The Caloris Thin Film Dryer is just the equipment needed for this zero-liquid discharge goal. Test It Out Pilot testing allows us to determine exactly which types of waste water treatment equipment are best suited for your needs. Caloris has a suite of pilot testing units that can be shipped to you for on-site testing, or you can send a sample to us. Simply call our main office at 410-822-6900 or send an email to problem.solved@caloris.com for more information. We can accept any size sample from a one-liter bottle to 55-gallon drums and totes at our dedicated testing facility in Cambridge, Md. Our engineers will work with you to determine the appropriate size sample to send. Customers are welcome to attend tests at our Cambridge location as well.

Craig has been with Caloris several years now. If you are attending this month’s Fuel Ethanol Workshop in Indianapolis, you’ll have a chance to meet Craig at Caloris Booth 201. Get to know Craig below. Caloris: How did you get involved in this field? Craig: My first job was with the U.S. Navy, working at Norfolk Naval Shipyard as a civilian on utility and process piping on nuclear fast-attack submarines. From there, I moved on to evaporation systems. Caloris: What do you enjoy most about working with customers? Craig: I like both the technical and commercial aspects of the relationship. I especially enjoy looking at their needs and designing the best systems for them. Caloris: What do you like most about working in Easton? Craig: I like that it is a beautiful waterfront community along the Chesapeake Bay. Caloris: What are your hobbies? Craig: I enjoy watching sports, especially baseball. I also enjoy fishing and listening to music, classic rock in particular. Caloris: What is your favorite cheese? Craig: Sharp cheddar. Caloris: What is your favorite ice cream flavor? Craig: Black raspberry. If you are interested in contacting Craig about one of our processing systems, or you need assistance with your current system, please send email to problem.solved@caloris.com or call us 410-822-6900.  

The mechanical evaporator process has been widely used for decades and in many industries to harness the energy efficiency of mechanical vapor compression devices to drive evaporation. Evaporation is a thermal process used for concentrating a liquid, where heat is delivered to the liquid to excite molecules of “volatile” components in the liquid to “boil,” causing those molecules to transition from liquid to vapor phase, which allows them to separate away from the liquid. For example, boiling beef stock in a pan over a burner on a stove, or in a hot oven, evaporates water from the boiling liquid and reduces or concentrates the beef stock solids. MVR stands for Mechanical Vapor Recompression. MVR turbofans generate heating vapors by compression of the water vapors evaporated from the product. Steam has long been used in industrial plants as an effective means of delivering heat throughout a facility, releasing ~1000 BTUs of thermal energy across a heat transfer surface for each pound of steam (water vapor) that condenses on one side of the surface. The condensed steam (hot water) can then be collected and pumped back to the steam boiler. When used for an evaporation process, the liquid on the other side of the heat transfer surface absorbs the heat released from the condensing steam, promoting volatile components in the liquid such as water to evaporate from that liquid. The mechanical evaporator process offers an alternative to steam from a boiler as the heat delivery source, utilizing a mechanical device such as a compressor or turbofan to generate the heating vapors (steam) required on the heating side of the heat transfer surface. Water vapors releasing away from the boiling liquid on the heated side of the heat transfer surface can be ducted into the compressing device and mechanically compressed to a higher pressure, and therefore a higher temperature. Those compressed vapors can then be directed to the heating side of the heat transfer surface where they can re-condense and transfer their thermal energy across the surface to heat the liquid and promote evaporation of more vapors that can be compressed to maintain the evaporation process. While many types of energy can be used for mechanically turning the drive shaft of the compression device, the most common is an electrical motor, allowing use of the mechanical evaporation process to operate an evaporation system anywhere electrical power can be delivered. Even at a remote plant site with no available utility supplies, where the electrical power needs to be locally generated. Deciding to use a mechanical evaporator process design usually depends on the cost of electrical power at the operating site as compared to the cost and availability of steam generation. Where steam is readily available at a reasonable cost, a steam-heated evaporator process can be installed at a competitive initial capital cost. However, where electrical power costs are reasonably competitive, where additional investment is required to achieve sufficient steam generation capacity, or where environmental permitting requirements complicate installation and operation of steam generation systems, the mechanical evaporator process offers significant operational flexibility and capabilities for almost any evaporation application and operating capacity.
