For the Engineered Woods and Pellets industries especially, treating and reusing WESP wastewater can save millions of dollars per year in maintenance costs alone.

From an operations perspective, the equipment at the plant comes second only to personnel. If equipment function isn’t optimal, production will suffer. Maintenance tasks such as cleaning out WESP and RTO units to remove solids and contaminants can impact the bottom line. Such activities are not profitable; the maintenance can take hours and even weeks at a time and causes the plant to shut down, which impacts productivity. What if the equipment didn’t require constant cleaning or replacing? What if all that thick, dark wastewater didn’t have to be evaporated and disposed of?

What if the wastewater that currently comes out of the WESP could be recycled into process-ready water again? What if the WESP never had to receive already concentrated wastewater to begin with? Effectively treating and reusing WESP wastewater protects the valuable equipment from gumming, corroding, and slowing production. If the water that goes into the WESP is clean, maintenance downtime becomes less of a burden and hydroblasting is unnecessary. Not only that, but having to haul off wastewater and solids for disposal can also be greatly reduced or eliminated. ProChem’s CleanWESP™ chemical treatment program effectively treats WESP wastewater and feeds the treated water back to the WESP. Cleaner water into the WESP means a cleaner WESP and cleaner vapor entering the RTO.

CleanWESP is an all organic, proprietary process designed to reduce TSS, TDS, potassium and sodium oxides, and high chlorides (>1,000ppm that corrode stainless steel). This proven process uses coagulant and polymer to treat wood processing wastewaters specifically. It can be tailored to each application too, to ensure it addresses the unique issues occurring at a given customer’s site. In addition to the CleanWESP program, ProChem offers water treatment system design and integration services, operations and maintenance services, and ongoing service and support for its products. Stop spending weeks’ worth of man hours on maintenance activities. Instead, lower your operational costs and increase production potential by reusing process wastewater.
