Since no chemistry is added or removed, your process remains unchanged. Low Maintenance The EVAPORATIVE TANK ™ uses only two moving parts - a pump and low cost blower. All molded polyethylene components for solution security, the tank thickness is approximately 1/4" to 3/8". Other materials used are high-temp CPCV, polypropylene, PVC and stainless fasteners. The EVAPORATIVE TANK™ is the ONLY atmospheric evaporator with a lifetime no-leak warranty. Low Cost Totaling all costs: initial purchase, energy, maintenance - the EVAPORATIVE TANK ™ is the most cost effective in recovering 100% of the chemicals (dragout) from your rinse water, or in reducing the volume of spent solution and wastewater. When using natural gas for heat, the cost of evaporation is about $.06 per gallon. APPLICATIONS PLATING MACHINING PRINTING Recover Dragout Reduce Waste Volume Remove Water from Lubricants Dewater Wash Water ANODIZING PHOTO PROCESSING General Chemical Recovery Spent Solution Reduction Dewater Spent Rinse Water Remove Water from ANY Waste Water Solution If a bath can be air agitated without causing excessive foam, it should be well suited to this method of recovery. High cyanide baths and still nickels are examples of solutions that should be tested for foaming. A sample can be shaken in a glass jar to see if the foam disappears quickly. Evaporation eliminates water and leaves all the plating chemicals (and tap water impurities) in the process tank. If your bath is not continuously filtered (as are some bright nickels), you may want to consider using D.I. or R.O. water in the rinsing chain. THE "MAGIC" OF COUNTERFLOW RINSING The diagram at left illustrates the principles of counterflow rinsing. As the ladle representing dragout is moved from tank #1 to tank #2, the dragout is diluted by a ratio of 10 to 1. Each successive tank further increases this dilution ratio by 10 to 1. A tank #7 the dilution ration is 10 million to 1. HOW MUCH RINSE WATER DO YOU NEED? Counterflow rinsing reduces rinse-flow requirements making dragout recovery practical and inexpensive. The table indicates the water needed to produce a 5,000:1 ratio using most plating solutions, or 20,000;1 using chromic acid.
