Koepnick says some cleaning systems require up to 50 pounds of dry chemicals per day, which previously required workers to lift heavy bags of material overhead for dumping into small hoppers atop large tanks, creating dust and spillage. The conveyor’s hopper, with a dump height of less than 4-ft (122 cm), averts that problem.
Although the treatment chemicals are non-toxic and non-hazardous, Koepnick says, “Customers are happy that their wastewater clarification system doesn’t incur a dust problem.
“Most companies discharge cleaning water at the end of the day,” he concludes, “but the addition of automated conveying to the system enables our customers to re-use wastewater and/or discharge cleaner wastewater, reducing both cost and environmental impact.”
Oberlin’s DMax system has been used successfully to treat heavy metal, emulsified, vibratory and color dye wastewater. The company’s basic line of filtration equipment has been an integral part of precision grinding coolant technology, automotive paint/zinc phosphate lines and power plant salt crystallization systems for over 35 years.
