Dissolved air flotation is a common sewage treatment equipment, which has a good impurity removal effect for sewage with floating objects in the water body. Therefore, it is recognized by manufacturers in all walks of life that need sewage treatment. But after all, the air flotation machine is also a mechanical device, and it is…
If in the process of using the dissolved air flotation equipment, it is found that there is a lot of sludge inside, and many people think that they can add an appropriate amount of lime and ferrous sulfate to clean the sludge inside, then what else can be done besides this method? The way to…
Because the aquaculture wastewater has certain characteristics, the concentration of suspended solids is very high, and the suspension has a great influence on the biochemical system, so an air flotation separation device is installed at the front of the biochemical tank to remove suspended solids. The back end of the anaerobic system is equipped with…
High-efficiency ultra-atomization dissolved air flotation is a series of ultra-atomized dissolved air flotation products specially developed for advanced sewage treatment (including terminal phosphorus removal), reclaimed water treatment, and micro-polluted water source treatment. High-efficiency ultra-atomization dissolved air flotation has low effluent SS, low effluent TP, high dissolved air rate, high gas release efficiency, no blockage, good…
The degree of contamination of wastewater is characterized by the amount of mineral, organic and bacterial materials solved or unsolved in the water. Wastewater is treated by mechanical, chemical, physical or biological methods. Biological processes involve oxidation of organic substances in waste water in the form of suspensions, colloids and solutions by microbes. There are…
Slaughterhouse wastewater is the wastewater generated during the slaughtering and processing of livestock, which mainly contains high concentrations of nitrogen-containing organic compounds, suspended solids, dissolved solids, grease, protein, blood, minced meat, food debris, hair, feces and sediment etc, and may also contain a variety of bacteria harmful to human health. If direct discharge will cause…
Overview The meat processing industry is one of the largest consumers of all freshwaters used in agriculture and livestock worldwide. The slaughterhouse produces large amounts of slaughterhouse wastewater through slaughter process and system cleaning. Due to its high content of organic matter and nutrients, SWW requires critical treatment for sustainable and safe emission to the…
Dissolved air flotation is a machine that uses small bubbles or tiny bubbles to surface impurities in the medium. The air flotation device can be used for some fine particles in the water body whose specific gravity is close to that of water because of its own weight and it is difficult to sink or…
There are more and more users using dissolved air flotation machines. After purchasing, everyone needs to do some preparatory work before using them. So what needs to be done? The editor has sorted out the preparations before the start of the air flotation machine: Clean and fill the air flotation tank with clean water, flush…
Dissolved air flotation may appear abnormal when it is turned on. Today, the editor has sorted it out for you. I hope you can find out and deal with it in time when using the air flotation machine, so as to reduce the damage to the air flotation machine. The pressure gauge has no pressure:…
