How Rendac doubled wastewater treatment capacity. Within its existing footprint.
At its animal by-product processing facility in Denderleeuw, Belgium, Rendac expanded wastewater treatment capacity through a phased upgrade of the existing plant. Pantarein Water integrated BLUE FOOT's backwashable IPC® membrane technology to handle demanding rendering wastewater without requiring additional treatment space.
THE CHALLENGE
More wastewater. No extra space.
Production growth at Rendac's animal by-product processing facility increased the load on its existing wastewater treatment plant. High nitrogen concentrations, grease and organic residues complicated treatment. Rendac needed additional capacity while maintaining discharge compliance within the available plant footprint.
THE APPROACH
A phased plant upgrade. Built around membrane expansion.
Pantarein Water upgraded the existing biological treatment process, optimised aeration and introduced pretreatment ahead of a dedicated membrane section. BLUE FOOT's backwashable IPC® modules provided flexible membrane capacity for successive expansions, integrating with the existing treatment infrastructure.
THE RESULTS
More treatment capacity. A foundation for water reuse.
The upgraded installation doubled the documented wastewater treatment capacity from 720 to 1,440 m³/day. Further expansion brought the membrane installation to 48 modules across three project phases. The final phase added capacity designed to enable reuse of treated wastewater for cleaning and utility applications.
