Product Description & Application

Product Overview

The BHP dissolved air flotation unit is a professional, CE- and UL-certified pretreatment system designed for solid-liquid separation in industrial environments. It generates uniform microbubbles that attach to free oil and suspended contaminants, enabling rapid water clarification and is widely deployed in oily wastewater treatment projects across multiple industries. As a comprehensive DAF system, it provides reliable pretreatment for complex industrial wastewater streams containing grease, oil, and fine suspended particles.

Detailed Operating Description

The BHP dissolved air flotation unit serves as core pretreatment equipment for complex oily and high-turbidity industrial wastewater streams. Unlike conventional sedimentation systems, it employs high-pressure dissolved-air technology to generate large quantities of fine, uniform microbubbles. These microbubbles attach to grease, suspended solids, colloids, and flocculated particles within the wastewater, increasing buoyancy and rapidly transporting contaminants to the surface for centralized separation and sludge removal. This solid-liquid separation process is highly effective for removing low-density contaminants that resist gravity settling.

Manufactured in strict accordance with CE and UL industrial safety standards, this DAF system features standardized electrical configuration for safe, reliable industrial wastewater operation. It effectively removes low-density grease and fine suspended solids that resist conventional settling methods. The compact design offers clog-resistant operation, high separation efficiency, and low operating costs, significantly reducing downstream biological treatment load and improving overall wastewater treatment performance. The dissolved air flotation unit is particularly valuable in oily wastewater treatment applications where free oil and emulsified contaminants must be removed before biological treatment.

Key Competitive Advantages

• International Safety Compliance: UL and CE certification ensures design and manufacturing meet international industrial safety standards, supporting export projects worldwide. The dissolved air flotation unit is engineered for safe operation in diverse industrial environments.
• Superior Oil and Contaminant Removal: Specialized microbubble separation technology efficiently removes free oil, grease, and fine suspended solids, delivering high clarification rates. This DAF system achieves ≥95% removal efficiency for oil and suspended solids under standard operating conditions.
• Fast, Clog-Resistant Operation: Optimized hydraulic flow and dissolved-air design prevent clogging and enable continuous long-term industrial wastewater operation. The solid-liquid separation system maintains stable performance even with variable influent quality.
• Automated Control with Minimal Labor: Intelligent PLC control provides continuous feed, separation, and sludge discharge functions with minimal operator intervention. The dissolved air flotation unit is designed for unattended operation, reducing labor costs and human error.
• Durable Anti-Corrosion Structure: Industrial-grade anti-corrosion material extends service life and reduces overall project operation cost. This DAF system is available in carbon steel, 304 stainless steel, or 316 stainless steel construction to match specific industrial wastewater characteristics.
• Versatile Industrial Application: Addresses various high-oil and high-turbidity wastewaters in pretreatment and advanced treatment phases across multiple sectors. The oily wastewater treatment capability makes this dissolved air flotation unit suitable for diverse industrial applications.

Primary Application Industries

• Food Processing and Slaughterhouses: Removes animal fats and suspended flocs from meat and food processing wastewater. The DAF system effectively separates grease and proteinaceous solids that would otherwise overload biological treatment systems.
• Textile Printing and Dyeing: Separates fiber contaminants, floating dyes, and suspended solids from textile processing wastewater. This industrial wastewater application benefits from the solid-liquid separation efficiency of the dissolved air flotation process.
• Mechanical Industry: Treats wastewater containing cutting oil and lubricants from machining and oily petrochemical operations. The oily wastewater treatment capability is essential for meeting discharge limits in metalworking facilities.
• Petrochemical Industry: Enables oil-water separation and removal of floating contaminants from oily petrochemical wastewater streams. The dissolved air flotation unit provides reliable pretreatment for hydrocarbon-laden industrial wastewater.
• Pulp and Paper Industry: Recovers paper fibers and removes floating suspended contaminants from papermaking wastewater. This DAF system supports fiber recovery and reduces load on downstream treatment processes.
• Industrial-Park Wastewater Treatment Plants: Provides pretreatment to remove contaminants and reduce operating load on downstream treatment systems. The solid-liquid separation capability of the dissolved air flotation unit is essential for protecting downstream biological and membrane systems.

Integrated Treatment System Compatibility

This DAF system integrates seamlessly with BHP chemical-dosing systems, sedimentation equipment, A/O biological treatment systems, ultrafiltration (UF), and reverse-osmosis (RO) water-reuse systems, delivering a complete standardized solution for industrial wastewater treatment. The dissolved air flotation unit serves as the ideal pretreatment step for protecting downstream membrane and biological processes from oil, grease, and suspended solids fouling.
