Yimei is pleased to announce the successful shipment of a Dissolved Air Flotation (DAF) system with a daily capacity of 1,000 cubic meters for a paper mill in Ethiopia. The equipment has completed its factory inspection and is currently in transit to the project site.
Water is an essential resource for the pulp and paper industry, playing a vital role in various production stages from pulping to bleaching and papermaking. This has historically made the pulp and paper industry one of the largest water consumers, highlighting the critical importance of efficient wastewater management.
As a key process in paper mill wastewater treatment, our custom-designed and manufactured DAF system is engineered to remove suspended solids, fibers, ink, fillers, and floating pollutants from paper wastewater before the biological treatment stage.
This project demonstrates our steadfast commitment to providing reliable industrial wastewater treatment equipment to customers worldwide.
Project Location: Ethiopia
Industry: Paper Manufacturing
Treatment Capacity: 1000 m³/day
Equipment: Dissolved Air Flotation (DAF) System
Application: Primary treatment for paper mill wastewater
Equipment Material: Carbon Steel with Anti-Corrosion Coating (customizable)
The customer's paper mill wastewater contains high concentrations of suspended solids (SS), pulp fibers, and organic pollutants generated during the paper manufacturing process. Based on the characteristics of the wastewater, our engineering team designed a customized Dissolved Air Flotation (DAF) wastewater treatment system to maximize solid-liquid separation efficiency while reducing the load on downstream treatment units. This optimized industrial wastewater treatment solution helps improve the overall performance and operational stability of the wastewater treatment plant.
Compared with traditional gravity sedimentation, a Dissolved Air Flotation (DAF) system generates millions of fine microbubbles that attach to suspended solids, causing them to rapidly float to the water surface for mechanical removal. This process significantly improves solid-liquid separation and clarification efficiency while substantially reducing sludge volume.
For paper mill wastewater treatment, installing a DAF system before the biological treatment stage effectively stabilizes the influent water quality, improves the performance of downstream treatment processes, and enhances the overall efficiency of the industrial wastewater treatment system. It is an ideal pre-treatment solution for removing pulp fibers, suspended solids, and other floating contaminants generated during the paper manufacturing process.
Our 1800 m³/day Dissolved Air Flotation (DAF) system is a reliable and highly efficient solution for a wide range of industries, ensuring the effective removal of suspended solids from wastewater.
Equalization Tank: Stabilizing Flow and Water Quality
The wastewater first enters the equalization tank, where both the flow rate and water quality are stabilized.
Coagulation and Flocculation Tank: Forming Dense Flocs
The wastewater is then pumped into the coagulation and flocculation tank, where coagulants and polymers are added to form larger and denser flocs.
DAF Unit: The Core Separation Process
The conditioned wastewater flows into the Dissolved Air Flotation (DAF) unit, where dissolved air releases millions of fine microbubbles. These microbubbles attach to suspended particles, causing them to rapidly float to the water surface.
Scum Collection and Sludge Removal
The system is equipped with a mechanical skimmer that continuously removes the floating sludge into the sludge collection tank, while the clarified water is discharged to the next treatment stage, such as an MBBR, MBR, or other biological treatment process.
This process effectively reduces Suspended Solids (SS), Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), and pulp fibers, providing stable influent conditions for downstream treatment and improving the overall efficiency of the wastewater treatment plant.
As a leading wastewater treatment equipment manufacturer in China, we meet the diverse treatment requirements of different industries. This equipment was customized with several optimized features to meet the customer's specific project needs:
The entire DAF wastewater treatment system was manufactured, assembled, and tested at our factory before shipment to ensure reliable on-site commissioning.
