Ⅰ. principle
GQF type developed by Gongyuan CompanyShallow air flotation machine for papermaking wastewater treatmentIt is a fast air flotation system that successfully applies the "shallow pool theory" and "zero velocity principle" on the basis of traditional flotation theory. Through careful design, it integrates coagulation, air flotation, skimming, and scraping, and is an efficient equipment for water purification treatment.
Ⅱ. advantage
1. The effective water depth is relatively shallow, ranging from 750-950mm
2. Short hydraulic retention time in the pool (5-10 minutes)
3. Large purification capacity and high surface load
4. Small footprint, light unit load, all prefabricated components assembled without the need for an operating room. The equipment can be installed overhead or in multiple layers. The installation and maintenance costs are low and easy to clean
5. High degree of purification, with a removal rate of over 90% for suspended solids such as algae, and a sludge concentration of 35% after concentration
6.Shallow air flotation machine for papermaking wastewater treatmentAdopting the GFA type gas dissolution system, it has a clever structure and a gas dissolution efficiency of over 98%. It has multiple self-developed technologies from various sources and possesses strong anti clogging capabilities that other gas dissolution devices do not have
Ⅲ. Application scope
1. Applied to algae removal and turbidity reduction in water plants using lakes as water sources
2. Applied to industrial wastewater treatment projects, such as petrochemicals, textiles, printing and dyeing, electroplating, leather making, food industry, etc
3. Applied to the recovery of useful substances in wastewater, such as fiber recovery in papermaking, pulp water, and other fields
