Full Guide

Food and beverage processors face rising costs and tightening regulations around wastewater treatment. Water is central to every stage of production—from ingredient processing to equipment cleaning—yet much of it ends up as high-load effluent. The challenge is twofold: reduce water consumption and treat wastewater efficiently without driving up energy and maintenance costs.

This guide from Robuschi outlines how to optimize wastewater treatment (WWT) using low-pressure air systems and robust equipment designed for variable loads and harsh environments. It breaks down the treatment process into four stages and highlights how Robuschi’s PD blowers and screw compressors support each step with energy-efficient, low-maintenance performance.

Key Takeaways

  • Water Use Is a Major Cost Driver

Water is used extensively in food and beverage production. Reusing treated wastewater for boilers and cleaning can reduce consumption and costs.

  • Effluent Loads Are Highly

Variable Wastewater contains high levels of BOD, COD, TSS, fats, and nutrients. Load shocks, temperature shifts, and production changes challenge conventional systems.

  • Four-Stage Treatment Process
    • Pre-Treatment: Screens remove large solids.
    • Primary Treatment: Filtration removes up to 60% of suspended solids.
    • Secondary Treatment: Aerobic/anaerobic processes remove organic matter.
    • Tertiary Treatment: Disinfection via chlorine, UV, or ozone.
  • Aeration Is the Cost Center

Aeration systems consume over 60% of total electricity in WWT. Up to 75% of compressed air costs are energy-related. Efficient blowers can cut lifecycle costs significantly.

FAQs

High concentrations of organic matter, fats, oils, and suspended solids vary widely depending on production cycles, making consistent treatment challenging.
