Package DAF system Product Overview
Halal slaughterhouse wastewater is a type of high-concentration organic wastewater. It is characterized by a reddish-brown color, a strong, and contains large amounts of blood, grease, hair, visceral residues, and feces. The key challenges in treating this wastewater are its high Chemical Oxygen Demand (COD), high Ammonia Nitrogen (NH3-N), and high Suspended Solids (SS). Without proper treatment, it poses a severe risk to the local environment and cannot meet discharge standards.
Package DAF system Factory Direct Supply from Weifang, China
Package DAF system Core Working Principle
Our customized wastewater treatment system adopts a robust "Pretreatment + Biological Treatment + Deep Treatment" process to ensure stable effluent quality:
Pretreatment (Screening & DAF): Wastewater first passes through mechanical screens to remove large solids like hair and viscera. Then, it enters the Dissolved Air Flotation (DAF) system to effectively remove emulsified oil, blood, and suspended solids, significantly reducing the load on subsequent biological stages.
Biological Treatment (Anaerobic + Aerobic): We utilize the UASB (Upflow Anaerobic Sludge Blanket) or hydrolysis acidification process to break down large organic molecules. This is followed by the A/O (Anoxic/Oxic) process, which is highly effective in degrading organic pollutants and removing ammonia nitrogen and phosphorus through nitrification and denitrification.
Deep Treatment & Disinfection: After biological degradation, the water undergoes sedimentation and advanced filtration. Finally, it is disinfected to kill harmful bacteria, ensuring the treated water fully complies with local environmental discharge standards.
3. Why Choose Us?
Tailored for Halal Slaughter: Specifically designed to handle the unique characteristics of cattle, sheep, and camel slaughter wastewater (high blood and grease content).
Stable Compliance: Proven technology ensures the effluent consistently meets strict environmental regulations, protecting your plant from fines or shutdowns.
Odor Control Design: Our system includes enclosed structures and deodorization units to minimize odor impact on the surrounding environment.
One-Stop Solution: As a manufacturer experienced in both slaughter lines and environmental equipment, we provide seamless integration, saving you time and coordination costs.
Coagulation & Flocculation: Chemicals (coagulants and flocculants) are automatically dosed into the raw wastewater to form visible flocs (flocculation).
Dissolved Air Release: A portion of the treated effluent is recycled, pressurized, and saturated with air in the dissolved air tank. When released into the flotation tank, the pressure drop generates millions of micro-bubbles. Package DAF system
Solid-Liquid Separation: The micro-bubbles attach to the flocs, forming "bubble-particle" aggregates that float to the surface. A mechanical skimmer continuously removes the floating sludge, while clarified water is collected from the bottom.
Package DAF system Key Advantages
High Separation Efficiency: Capable of removing over 90% of Suspended Solids (TSS) and 80-90% of Fats, Oils, and Grease (FOG), significantly reducing COD/BOD loads.
Compact & Space-Saving: The integrated design (including reaction tank, flotation tank, and dissolved air system) requires a much smaller footprint compared to traditional sedimentation tanks.
Rapid Installation: Available in skid-mounted or containerized designs, the equipment is pre-assembled and tested at the factory, allowing for plug-and-play installation on-site.
Fully Automatic Operation: Equipped with a PLC control panel and automated dosing system, it supports unattended operation, reducing labor costs.
Versatile Applications: Suitable for a wide range of industries including food processing, slaughterhouses, paper mills, petrochemicals, and textile dyeing.
Typical Applications（Package DAF system）
Food & Beverage: Slaughterhouse wastewater, dairy processing, edible oil refining, and beverage production.
Pulp & Paper: White water recovery and fiber recycling.
Oil & Chemical: Refinery wastewater, oil-water separation, and petrochemical effluent treatment.
Municipal & Others: Algae removal in drinking water, sludge thickening in sewage plants, and landscape water purification.
(Note: Specifications can be customized based on specific influent water quality, such as high oil content or corrosive chemicals, and discharge standards.)
