Center Enamel Provides UASB Technology for Dairies Wastewater Treatment

Dairy processing plants generate large volumes of high-strength wastewater containing organic matter, fats, proteins, and suspended solids. Proper wastewater treatment is essential to comply with environmental regulations, protect water resources, and enhance sustainability efforts.

As a leading provider of anaerobic wastewater treatment solutions, Shijiazhuang Zhengzhong Technology Co., Ltd (Center Enamel) offers Upflow Anaerobic Sludge Blanket (UASB) technology, a highly efficient and cost-effective solution for dairy industry wastewater treatment. Our UASB reactors enable high organic load removal, reduce operational costs, and facilitate biogas recovery, transforming waste into energy.

Challenges of Dairy Wastewater Treatment
High COD & BOD Levels – Dairy wastewater has elevated Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) due to the presence of milk residues, lactose, proteins, and fats.

Variability in Flow & Composition – Wastewater characteristics change based on dairy product types, production schedules, and cleaning processes.

High Fat & Protein Content – The presence of fatty acids and proteins can cause foaming and treatment inefficiencies in conventional systems.

Energy-Intensive Treatment Requirements – Aerobic treatment methods consume high amounts of electricity, increasing operational costs.

Why UASB Technology for Dairy Wastewater Treatment?
Upflow Anaerobic Sludge Blanket (UASB) technology is an advanced anaerobic digestion process that efficiently removes organic pollutants while generating biogas for renewable energy applications.

High Organic Load Removal Efficiency – COD and BOD reductions of 85–95%, making it an effective pre-treatment before discharge or further polishing.

Biogas Recovery & Renewable Energy Production – Converts organic waste into methane-rich biogas, which can be used for steam generation, electricity production, or heating.

Low Energy Consumption & Reduced Operating Costs – Unlike aerobic systems, UASB reactors require minimal energy input, reducing aeration costs.

Compact System with High Treatment Capacity – UASB reactors efficiently treat high organic loads in a small footprint, making them ideal for dairy plants with limited space.

Reduced Sludge Generation – Anaerobic digestion produces less excess sludge compared to aerobic systems, minimizing sludge disposal and handling costs.

How UASB Technology Works for Dairy Wastewater
Pre-Treatment – Dairy wastewater undergoes screening, pH adjustment, and oil-fat separation to optimize conditions for anaerobic digestion.

UASB Reactor Process

Wastewater enters the UASB reactor, flowing upward through the granular sludge blanket.
Anaerobic microorganisms break down organic matter, converting it into biogas.
The three-phase separator efficiently separates biogas, sludge, and treated water.
Biogas Collection & Utilization

The captured biogas can be used for boiler heating, power generation, or other energy applications, reducing reliance on fossil fuels.
Effluent Treatment & Compliance

Treated wastewater can be further polished through aerobic processes or directly discharged according to environmental standards.
