Wastewater Treatment in a Food Factory with Megaflux-MBR

Food manufacturing wastewater is rich in biodegradable organics and fats, oils & grease, with production and CIP cycles causing sharp swings in load, pH, and temperature. Conventional clarification struggled with solids carryover and variability, risking non-compliance and excessive maintenance.

The client needed a compact solution that could handle peaks and emulsified solids while delivering consistently clear effluent suitable for discharge and potential reuse.

We engineered a 500 m³/d MBR. Headworks screening and equalization feed an aerobic submerged-membrane bioreactor. We installed the MBR and sized the system to operate within the typical industrial MBR flux window for robust, low-fouling performance. Where reuse/RO is planned, the system is configured to meet RO pretreatment targets.

The MBR consistently produced sub-NTU, near-zero-TSS permeate, enabling reuse or RO polishing. With equalization and conservative flux, it maintained throughput and compliance during production/CIP peaks, while eliminating secondary clarification, reducing footprint, and simplifying O&M.
