Dissolved Air / Gas Flotation Separators - Sewage Treatment

Dissolved Air Flotation (DAF) System : Dissolved Air Flotation (DAF) is a Physio-Chemical Treatment where air is intimately contacted with an aqueous stream at high pressure, dissolving the air. The pressure on the liquid is reduced through a back pressure valve, thereby releasing micron-sized bubbles that sweep suspended solids and oil from ...

Techniques for separation of plastic wastes - ScienceDirect

2019.1.1 About 27.1 million tonnes of plastic waste were collected in Europe in 2016 (Plastics The Facts, 2017), of which 31.1% was collected for recycling, 41.6% for energy recovery and 27.3% still went to landfill.Even if the percentage of recycled plastics is quite low, a positive aspect is that in the past 10 years (from 2006 to 2016) plastic waste

Separation of Oil from Wastewater by Air Flotation

2010.1.1 Air flotation, in all its variations, is an efficient way to extract oil from wastewater. If the wastewater is chemically pretreated to break the oil emulsions, air flotation units are capable of removing most of the emulsified oil in addition to the free oil. This chapter covers various flotation techniques to achieve oil/water separation.
