Revolutionizing Dairy Wastewater Treatment with MBBR Technology

Dairy wastewater is rich in organic matter, fats, and nutrients. Plants producing milk, cheese, and yogurt need robust, efficient treatment to meet stringent discharge requirements.

Wastewater from dairy facilities is commonly characterized by:

• High BOD and COD: Milk solids, lactose, and proteins create high-strength organic wastewater.
• Elevated fats, oils, and grease: FOG can clog equipment and hinder biological treatment.
• Fluctuating loads: Production schedules, Clean-In-Place cycles, and product changeovers vary wastewater flow and composition.
• Nutrient content: Nitrogen and phosphorus may need removal before discharge.

Traditional systems can struggle with these fluctuations and may require a large footprint, creating a constraint for existing facilities.

A Moving Bed Biofilm Reactor uses thousands of small, free-floating plastic media carriers in an aeration tank. Their high surface area provides a protected environment for a dense microbial biofilm.

As wastewater moves through the tank, microorganisms consume organic pollutants and convert them into harmless byproducts. Continuous aeration keeps the media mixed and maintains effective contact between the biofilm and contaminants.
