Product Description

INTRODUCTION

Our Gongyuan GQF Type Superficial DAF is an advanced quick-speed flotation system integrated with flocculation, flotation, skimming and mud scrapping. Based on the traditional flotation theory, we also use the"shallow theory" and "principle of zero speed" successfully. Thus our superficial air flotation is widely applied in waterworks removing alga, vare and other turbic water from nature lake and river; Industrial sewage treatment projects such as petro-chemical, textile, printing and dyeing, electroplating, tanning, food industry and other fields;Recycling useful material in sewage like fibre recovery on paper & pulp industry.

FEATURES

* Shallow effective water depth: 750mm~950mm.

* Short hydraulic retention time: 5~10min.
* Large purification capacity, namely high surface load.
* Small footprint, light unit load, all prefabricated assembly, overhead installation or multi-layer combination mounting.
* Low cost of installation and maintenance, easy to clean.
* High purification degree, algae and other suspended solids removal rate over 90%, thickened sludge concentration can reach 35%.
* Our superficial DAF will use GFA Type dissolved air system with its ingenious structure. The GFA dissolved air system has the strong anti-clogging ability.
