Industrial water treatment systems take a variety of forms. Among the most common include the dissolved air flotation system, the water oil separator system, the aerobic treatment system, and the induced gas flotation system. These water treatment systems vary from one another in both their principles of operation and the purposes for which they were…
The so-called electrolytic air flotation method is a method of air flotation water treatment. During the electrolysis process, under the action of a direct current electric field, tiny bubbles of hydrogen and oxygen are generated at the cathode and anode respectively, which have a chemical redox effect on the pollutants in the wastewater, and can…
A great way to deal with algae, fat, oil and grease (FOG) is to install a Dissolved Air Flotation (DAF). However, many face difficulties in operating the device and therefore, plant fails. First of all, it is important to know which type of DAF are you integrating in your system; whether it is a gravity…
Dissolved Air flotation is mainly used to remove suspended impurities density of which is closed to that water. These impurities can not either settle naturally or float naturally. DAF has the advantages of high separation efficiency and simple structure. The dissolved air flotation will directly affect the effluent quality. The poor effect of the dissolved…
Dissolved air flotation Waste management is a big challenge today because we are producing more garbage and sewage than our existing infrastructure can handle. This has huge implications for the environment and puts the spotlight back on climate change and the role of humans in it. To mitigate this negative impact on the environment, many…
Dissolved air flotation (DAF) for industrial wastewater treatment is a water clarification process that uses micro-bubbles to remove impurities and solids. The process is ideal for removing light impurities and solids that tend to float and suspend ( such as TSS, BOD, COD, and pollutants) in your wastewater. The DAF process is in contrast to…
A typical DAF system should includes: 1. Screening Adequate screening to remove gross solids from trade waste influent, buffering and treatment steps is crucial as it: Prevents solids blocking/damaging wastewater feed pumps, DAF recycle pumps and sludge pumps. Limits odours produced by anaerobic degradation of settled sludge that build up in the DAF unit and…
