Conveying line elbows provide maintenance-free operation
A wastewater reclamation plant installs 17 specially designed elbows in its lime conveying systems to eliminate dust leaks and downtime caused by material abrasion.
The Upper Occoquan Sewage Authority (UOSA) operates an advanced water reclamation plant in Centreville, Va., that treats more than 30 million gallons of wastewater each day. One step in the reclamation process -- transferring pebble lime from bulk trucks to storage silos -- was proving to be a challenge for the plant. The lime eroded through the pneumatic conveying system elbows too quickly, causing dust leaks, excessive downtime, and inefficient operation.
