Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters by removing suspended matter such as oil or solids. This is achieved by dissolving air into the water under pressure and releasing it, causing air bubbles to adhere to suspended particles and causing them to float. DAF is widely used to treat industrial wastewater from facilities like oil refineries, chemical plants, and paper mills. A similar process called induced gas flotation is also used for wastewater treatment. In the mineral processing industry, froth flotation is commonly used to separate minerals.

Canoy, Claire E. 2B2- Chemical Engineering Technology Unit Operations Engr. Luna FLOATATION Dissolved air flotation (DAF) is a water treatment process that clarifies wastewaters (or other waters) by the removal of suspended matter such as oil or solids. The removal is achieved by dissolving air in the water or wastewater under pressure and then releasing the air at atmospheric pressure in a flotation tank or basin. The released air forms tiny bubbles which adhere to the suspended matter causing the suspended matter to float to the surface of the water where it may then be removed by a skimming device. Dissolved air flotation is very widely used in treating the industrial wastewater effluents from oil refineries, petrochemical and chemical plants, natural gas processing plants, paper mills, general water treatment and similar industrial facilities. A very similar process known as induced gas flotation is also used for wastewater treatment. Froth flotation is commonly used in the processing of mineral ores. In the oil industry, dissolved gas flotation (DGF) units do not use air as the flotation medium due to the explosion risk. Nitrogen gas is used instead to create the bubbles. FLOATATION CHART
FLOATATION REAGENTS Xanthate Application: It has a strongest collector ability for sulfide mineral, and also can be used as diferential flotation reagent for non-ferrous ore. It’s commonly used in lead and zinc ore galena mixed priority of the flotation. Dithiophosphate Application: It is efficient collecting agent for sulphide ores such as sliver sulphide, copper sulphide, lead sulphide and activation zinc sulphide ore, and also can be used in flotation of nickel and antimony sulphide ores.Especially, it is efficient for nickel sulphide ore, nickel oxide sulphide ores which are difficult for flotation, sulphide copper and gangue ore. Based on the research that to use butyl amine aerofloat is beneficial for recycling of platinum, gold and silver. This chemical has a light foaming ability. Thionocarbamate Application: Thionocarbamate is an excellent catching agent for copper sulphide, lead, zinc, molybdenum, nickel and other minerals. It is the best catching agent of copper sulphide, efficient, non-poisonous, and has excellent selectivity, so it is widely used in the world. It also have foaming ability by itself, so can be used in acidic or alcaline ore pulp.
Thioglycollic Acid Application: In addition of being used as the textile auxiliary & the leather tanning chemicals instead of Sodium Hydrosulfide; It also can be used in the main raw material of cosmetics such as cold wave lotion and depilatory. Besides; It also can be used to modulate into PVC and organic stibium and organic tin. Isooctyl Thioglycolate, which is produced from this product after intensive processing, is a heat stabilizer of non-toxic chlorinated polyolefin Last, but not least, it acts as an important agent for metallic ion such as iron, molybdenum, silver and tin, etc.; It’s also used in catalyst production in epoxy resin and bisphenol A. Thioglycolate Salt Application: It is used as a depressor for copper mineral and brasses in copper-molybdenum mine flotation. It is produced with advanced technology and excellent craft. It has been used with long period in many molybdenum flotation factories in China. It has obvious depressor effect for copper, sulphur and other material, so it will effectively improve the molybdenum concentrate level and bring high economic profit to enterprise. It has been used as a new-model effective depressor for vulcanization mine in molybdenum flotation process and can take place of highly toxic depressor sodium cyanide. This product has been sold to Henan Luanchuan, Shanxi Luonan, Fujian JIanyang, Liaoning Huludao etc, and welcomed by our clients. In molybdenum flotation process, it can not only depress lead, zinc, iron, copper and other metal impurity, but also has good effect to decrease silicon, sulphur and other non-metal material. This agent needs only a small dosis, and the usage is easy and convenient, so it can save cost and improve the economic profit. This product not only can improve the quality, but also without pollution and hazardous, so it will take positive effect to environment protection of the producing area. It is an environment protection product and without pollution, which is positively recommend by the national environment protection department.
Dithiocarbamate Application: It is effective collctor for copper, lead, antimonite and other sulfide minerals. It has better collectivity than xanthate and dithiophosphate, which is with fast flotation speed and excellent selectivity. If it is used in flotation under high alkali conditions, it can improve the separation flotation effect between lead and zinc, with little or without any cyanide. Isopropyl (ethyl,isobutyl) xanthogen ethyl formate Application: It is a collecting agent of nonferrous metal mine, which has better flotation effect than the related xanthogenate, also has more steady character and could be used in acidic pulp . It has a better effect in flotation of separating copper and sulphur. Rinsing Reagent Application: As Flokal B or Rinsing Reagent，it is mainly used as oil-removed rinsing reagent in sewage of oil field or recycled water, or used to remove the heavy metal ion from industry sewage. As an oil-removed rinsing reagent in sewage of oil field or recycled water, it is mainly used in gas flotation device for removing oil from sewage of oil field. First, the oil in sewage can be flocculated and removed by gas flotation to make the oil content of sewage reach to the standard, and then the sewage is quantified to be discharged or recycled. Specific usage and dosage: after diluting it by 10 times, put it into the sewage, the dosage is to use 50-1000g for one liter sewage. According to the different dosage and oil concentration of sewage, the removing percentage of oil in sewage can be above 90%. As a rinsing reagent used in sewage of oil field, it has better oil-removing effects than usual
oil field flocculant--- polyaluminium chloride(PAC), and it has overcame the disadvantages of huge scum quantity, flco dispersion, breakable and huge liquid water content (>95%) and so on when PAC is used in oil-removing process. Meanwhile, it has the effect of emulsion splitter and flocculant, so it has solved the problem that we must use two or more than two emulsion splitters and flocculants to remove oil and clean water. Only using it, you can get the effects of oil demulsification in water and flocculant, then you don’t need to add any other chemicals. It has already been used in the oil fields of South China Sea, Indonesia and so on. ZXT Effective Collector For Copper Application: It is formula product that aimed at copper flotation, and has the excellent collecting effect. It is an efficient, non-toxic, excellent copper collecting agent. ZX Depressor Application: It is series products that aimed at different mineral characteristic, and different brands can be chosen with different situations. It is efficient depressor in molybdenite flotation without using cyanogen, which can take place of sodium cyanide and sodium sulfide, and optionally depress copper and sulphur in molybdenite, especially has the apparently depressing effect with copper sulphide and pyrite. Based on different contents of copper, sulphur and lead in ore, it can be added with one time and one length or many times and many lengths. The dosage should be based on flotation experiment, and it is normally used in alkalic pulp.
ZXH EFFECTIVE COLLECTOR Application: It is a compound efficient collecting agent that combined with many kinds of agentia, which is mainly used in flotation of nonferrous metals mine. Different brands of this serie can be used with different characteristics of ore and different requirements of flotation. It has the characteristics of high pertinent and excellent flotation effect. ZXM Frother Application: It is mainly used as foaming agent in flotation of coloured and rare metal and coal, which has the advantages, such as steady function, strong foaming ability, fast floating speed, excellent adaptbility to ore, substantial foam layer, easy to operate, non-toxic, in favor of improving environment and decreasing pollution. Different brands of this serie can be used with different characteristics of ore .It has the characteristics of high pertinence and good foaming effect.
