Product DescriptionIntroduction with Dissolved Air FlotationThe working principle of the Dissolved Air Flotation (DAF) unit is to attach bubbles to suspended solids in water, increasing their buoyancy and causing them to float to the surface, forming a layer of scum that is then skimmed off. This equipment is widely used in the pretreatment of industrial wastewater and can replace sedimentation tanks, offering higher efficiency and space-saving advantages.SpecificationModelTreatment Capacity(m3/hr)Tank Size(m)IdIer Weight(T)Back-flow pump(kw)Air Compressor(kw)Skimming Device(kw)Mixer1Full-load Weight(T)Mixer2DUBHE-DAF10104*2*23.530.550.10.559.50.55DUBHE-DAF25255.9*2.35*2.1453.70.750.10.75170.55DUBHE-DAF50507.6*2.8*2.266.55.51.50.21.127.50.75DUBHE-DAF80808.7*3.4*2.428.57.51.50.21.1450.75DUBHE-DAF1001009.4*3.8*2.4210112.20.41.5561.1DUBHE-DAF15015011.3*4.4*2.7214.51530.41.51001.1DUBHE-DAF20020017.5*3.8*2.7218.518.540.81.51181.1Applications1. Municipal Sewage: Used in the pretreatment stage to remove light impurities such as fats, oils, and fibers.2. Petrochemical Industry & Oily Wastewater: Effective in oil-water separation, including emulsified oils and vegetable oils.3. Textile, Printing, Dyeing & Wool Processing: Ideal for pretreatment of wastewater from these industries.4. Surface Treatment Industries: Suitable for wastewater treatment in electroplating, PCB manufacturing, and acid cleaning.5. Paper, Leather, Slaughterhouse, Food & Beverage, and Pharmaceutical Industries: Efficient pretreatment solution for various industrial effluents.Seawater Desalination: Effectively removes algae, colloids, and fine particles, with notable efficacy in treating floating oils and shipboard oily wastewater.Structure & principleThe air floatation separation technology is used to achieve the purposeof purifying water quality.When flocculants (PAC or PAM or other flocculants)added into the water, after effective flocculation(time, dosing and flocculation effect must be tested), the water flows into thecontacting area where the tiny bubbles adheres to the flocculants andthen flow to the separation area where both the flocculants and the tinybubbles float to the surface ofthe water forming scum which is removedby a skimming device. The treated water flows into branch water pool,partially back-flowing for the DAF system and the rest discharged.Skimming DeviceAir Dissolution TankDissolved Air Release DeviceCompany ProfileShanghai DUBHE Environmental Protection Technology Co., Ltd.As a leading manufacturer and solution provider in the wastewater treatment industry, DUBHE specializes in the R&D, production, and global supply of high-performance environmental equipment.
