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:…
DAF systems are commonly used for the removal of oils & greases and suspended solids to meet a variety of treatment goals including: Product recovery and reuse. Pretreatment to meet sewer discharge limits. Pretreatment to reduce loading on downstream biological treatment systems. The treatment goals include: Product recovery and reuse Pretreatment to meet sewer discharge…
We summarizes some experience and skills to help you improve the processing capacity and reduce the operation cost. The on-site management and operation personnel of the sludge dewatering machine need to constantly observe and adjust in time, so as to achieve the best state and relatively stable cooperation in various changes as far as possible….
Landscape water treatment. Biochemical reaction after the depth of treatment. The clarification of white water and fiber recovery in the paper industry. Chemical, steel, food and other industrial wastewater physical and chemical treatment. Remove industrial wastewater suspended solids, oil, grease and organic matter. As a DAF water treatment plant manufacturer, IEPP can supply dissolved air…
Clean and safe water is a necessity for everyone. With the demand for water increasing by the day, wastewater treatment plants are designed to treat water and return it back to the environment safely. However, our traditional wastewater systems are far from efficient in terms of operation and cost. Here are some of the biggest…
