There's no reason to buy an expensive waster water evaporator machine when you can build a simple evaporation tank. Using our electric immersion heaters, they can handle the most notorious chemicals such as chlorides, fluorides and tough acids. Because acids are heavier than water, the water evaporates leaving the concentrated liquid for disposal. It takes 965 Btu’s at 212°F, to evaporate 1 lb of water. A waste water evaporation system consisting of a PTFE lined tank and corrosion resistant sheath material, such as Stainless Steel, Titanium, Quartz or a PTFE coated heater, can handle most caustic solutions.
Use a Quartz heater for sulfuric and phosphoric acids. The wastewater from phosphoric acid is very viscous along with the removed metals, this sludge will have a tendency to build up on the outer sheath on the Quartz Immersion Heater.
The use of level safety control and sensors to shut off the heating equipment is needed.
