DAF Pretreatment for Slaughterhouse Wastewater

Home > Projects > DAF Pretreatment for Slaughterhouse Wastewater

Dissolved-air-flotation unit removing fats, blood solids and suspended matter ahead of biological treatment at a slaughterhouse.

Project Background

Slaughterhouse effluent carried high fat, oil and grease and suspended solids that overloaded the downstream biological stage.

Our Solution

A DAF unit with chemical conditioning (PAC/PAM) installed as pretreatment so the biological stage receives a stable, degreased feed.

Equipment Used in This Project

Dissolved Air Flotation (DAF) System

Dissolved Air Flotation (DAF) System

ZSQ series dissolved air flotation (DAF) system for high-efficiency removal of suspended solids, FOG, oil & grease, and colloidal matter from industrial wastewater. Micro-bubble technology with automatic skimming handles 4–300 m³/h across 13 standard models. Proven in food processing, pulp & paper, textile, metalworking, petrochemical, and municipal pre-treatment applications.
Automatic Chemical Dosing System

Automatic Chemical Dosing System

HydropureWater automatic chemical dosing systems provide precise, PLC-controlled injection of coagulants, flocculants, pH adjusters, and specialty chemicals for water and wastewater treatment. Skid-mounted, pre-wired, and factory-tested for rapid installation.
