v Severe Challenges in Industrial Wastewater Treatment and Breakthrough Solutions

Aiming at the pain points of treating grease, colloids, and suspended solids in industrial wastewater, traditional processes often lead to system shock and high energy consumption. The dissolved air flotation (DAF) machine, with the Niconi pump as its core component, relies on its high-efficiency solid-liquid separation capability to thoroughly revolutionize traditional operation modes. It is the preferred treatment solution for overcoming complex water quality challenges and achieving low-cost, stable operation.

v What is a Nikkuni Pump Dissolved Air Flotation (DAF) Machine?                                       

The Nikkuni Pump DAF Machine (CXNF Series) is a highly efficient flotation equipment specifically designed to remove grease, colloids, and suspended solids from industrial and domestic wastewater. Unlike traditional DAF machines, its core innovation lies in replacing the conventional air compressor, pressure pump, and dissolved air tank with a Nikkuni pump.

v This equipment utilizes an in-pump pressurized mixing mechanism.

 As it draws in water, it simultaneously and automatically aspirates air. The negative pressure generated by high-speed rotation pulls the air in, allowing it to mix thoroughly with the water inside the pump to directly produce micro-bubbles with a particle size of merely 20-50 microns. This integrated design not only significantly simplifies the equipment structure but also achieves a breakthrough in oil removal rates, typically exceeding 95%. When combined with appropriate chemical agents and flocculants, the machine can remove over 60% of COD and BOD during the pretreatment stage, making it a true powerhouse for industrial wastewater pretreatment.

v Main Structure and Workflow: The Art of Simplifying Purification

1. High-Efficiency Dissolved Air and Recirculation:

A portion of the treated clean water is recirculated and pumped directly into the Nikkuni pump. During the pressurized delivery process, the pump simultaneously draws in water and air, completing the gas-liquid mixing inside the pump to form dissolved air water rich in micro-bubbles.

2. Mixing and Release:

The untreated wastewater enters the flotation tank and thoroughly mixes with the dissolved air water released by the Nikkuni pump as it rises. Due to the unbalanced upward buoyancy between the gas-liquid mixture and the liquid, the micro-bubbles rapidly attach to the suspended solids.

3. Flotation Separation:

Driven by buoyancy, the suspended solids attached to the micro-bubbles are carried to the water surface. Supported by the bubbles, they accumulate to form a sludge (scum) layer.

4. Sludge Scraping and Discharge:

The sludge on the water surface is cleared by radially directed airflow thrust. A sludge scraper moves at a constant speed across the entire liquid surface, pushing the suspended solids from the inlet end to the outlet end, where they are ultimately discharged through the sludge discharge pipe.

5. Clarified Water Overflow:

The purified water is smoothly discharged through the bottom overflow pipe and proceeds to the next treatment stage.
