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…
Sludge poses significant problems for wastewater treatment plants. With its pathogen content and unstable nature, sludge is a hazard to both human health and the environment. What can we do about it? The answer is to aggressively process it, reduce pathogen levels, and stabilize the biosolids. There are several traditional sludge processing methods — namely…
Wastewater treatment plants are facing major operational problems of bulking and foaming. Biological treatment process is to remove biodegradable pollutants from wastewater. Biodegradable constituents’ pollutants are metabolised by microorganism in the activated sludge. Biodegradable consuming rate is the deciding factor for oxidation and separation process performance of wastewater treatment. The poor separation problem is caused…
What is Chemical Oxygen Demand (COD)? COD is defined as the amount of a specific oxidant (expressed in its oxygen equivalence) that reacts with a sample with organic substances under controlled conditions-Dichromate ion (Cr2O72-) is reduced to its chromic ion (Cr3+). COD is an indirect measure of the amount of organics in a water sample….
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:…
