Enhancing Efficiency and Reliability through Advanced DAF and Lamella Clarifier Technologies
Wastewater pretreatment is an essential step in ensuring the stable and efficient operation of any industrial or municipal water treatment system. As a global provider of solid–liquid separation technologies, Jorsun Environment offers advanced pretreatment solutions designed to remove suspended solids, grease, and impurities that can negatively impact downstream processes.
With over two decades of industry experience, Jorsun Environment specializes in manufacturing Dissolved Air Flotation (DAF) systems and Lamella Clarifiers, two core technologies widely used across food processing, chemical, industrial, and municipal wastewater applications.
1. Importance of Pretreatment in Wastewater Treatment
Effective pretreatment plays a crucial role in:
• Protecting downstream equipment
By removing coarse solids and contaminants, pretreatment prevents blockages and reduces wear in pumps, pipelines, biological reactors, and filtration systems.
• Improving treatment efficiency
Stabilized influent quality allows biological and tertiary processes to operate at optimal performance.
• Reducing operational costs
Lower sludge production, reduced chemical consumption, and fewer maintenance interventions result in long-term cost savings.
• Ensuring stable and compliant discharge
Pretreatment minimizes fluctuations in water quality, protecting the entire treatment line.
2. Jorsun DAF System – High-Efficiency Removal of Grease and Suspended Solids
The Jorsun Dissolved Air Flotation (DAF) system is engineered for the effective removal of:
Fats, oils, and grease (FOG)
Suspended solids (SS)
Colloidal particles
Lightweight organic materials
Working Principle
Microbubbles generated by the air dissolution system attach to suspended particles, causing them to float to the surface. A mechanical scraper removes the floated sludge, producing clear effluent suitable for downstream processes.
Key Features of Jorsun DAF
High removal efficiency (up to 90–99% for FOG and SS)
Compact and modular design
Stable, low-energy operation
Ideal for food processing, meat & poultry, dairy, convenience food production, and a wide range of industrial wastewater
As one of Jorsun Environment’s flagship products, the DAF system has been successfully deployed in hundreds of installations worldwide.
3. Jorsun Lamella Clarifier – Advanced Sedimentation Technology
The Jorsun Lamella Clarifier, also known as the inclined plate clarifier, significantly improves settling performance while minimizing footprint.
Typical Applications
Removal of settleable solids
Treatment of inorganic and precipitated particles
Pre-sedimentation for chemical dosing systems
Pretreatment before biological processes
Benefits of Lamella Clarifier
3–5 times higher settling efficiency than traditional clarifiers
Compact structure and easy installation
Reduced sludge output and low maintenance requirements
Reliable performance in industrial and municipal facilities
Jorsun’s NLST series Lamella Clarifiers are widely used in electroplating, general manufacturing, surface treatment, food industry wastewater, and various pretreatment stations.
