Sedimentation & dissolved air flotation Solids and other particulates preferentially attach to the air bubbles and rise to the surface of the dissolved air flotation unit where they are collected, thickened and removed by a motorised scraper.Using established solids/liquid separation technology, the units generate “whitewater” by dissolving air under pressure and then releasing the pressure to form micro air bubbles.Main advantages 1. Extremely compact and efficient clarifier - with hydraulic loading upto 30 m/h.2. Lower capital cost versus traditional rectangular units for equal flows.3. Highly energy efficient - very high level of clarification with significantly lower pressurisation rate compared to traditional DAF clarifiers.4. Minimises polymer consumption by optimising flocculation with extended mixing time in presence of air bubbles and polymer.Main applications 1 White water clarification and fibre recovery in the paper industry.2 Clarification of de-inking effluents.3 Clarification of food and industrial effluents in combination with physical-chemical treatment.4 Biological tertiary treatment.5 Landscape waterModel and specificationModelCapacity(m3/h)Dissolved air water flow rate(m3/h)DimentionLXBXH(m)Refluence pump power(kw)Scraper powerSDAF32 30.5 11800X800X23001.10.25 SDAF 53 51 22000X800X2300 SDAF 105 102 32500X1000X23001.5 SDAF 1510 153 53000X1200X25003 SDAF 2015 205 73000X1400X2500 SDAF 3020 306 104000X1800X2500 5.50.25 SDAF 4030 408 134500X2000X27007.5 SDAF 5040 5015 205000X2200X27000.37 SDAF 6050 6015 206000X2300X2700 0.37 SDAF 7060 7020 256500X2400X3000 110.55 SDAF 8070 8025 287000X2400X3200 SDAF 10080 10030 357500X2500X3200 15
