INDUSTRY APPLICATIONS

YOSUN offers a wide range of bespoke industrial water, wastewater, and sewage treatment solutions.The applications of our DAF systems are virtually unlimited, as they can treat a wide variety of wastewater volumes and compositions and can be installed at any stage of the process, acting as primary, secondary or tertiary treatment.

Our equipment has demonstrated high efficiency in the removal of organic and inorganic suspended matter, floccules, oils and greases.

Surface Treatment

Metal surface treatment wastewater mainly comes from electroplating, anodizing, pre-treatment, and electrophoretic coating wastewater. It contains a lot of harmful substances, such as heavy metals, acid and alkali ions, and other substances.

Textile Dyeing

Printing and dyeing wastewater is generated during textile printing and dyeing production. It is one of the primary sources of pollution in the textile industry. Printing and dyeing wastewater contains a large amount of refractory organic matter, inorganic salts, and dyes, and the concentration of these pollutants is high, and the color is prominent.

Oil-and-Emulsion

The sources of oily wastewater are extensive. Oily wastewater will be produced in oil field mining, natural gas extraction, daily chemical production, food processing, pharmaceutical production, and metal processing. The composition and properties of oily wastewater in different industries are different.

Food Processing

The primary sources of food processing wastewater are a large amount of sand and debris, leaves, skins, scales, meat, feathers, hairs, etc., which enter the wastewater during the raw material cleaning stage, causing the wastewater to contain a large amount of suspended solids.

Landfill leachate

Landfill leachate mainly comes from landfills and incineration plants. However, with the development of garbage classification, biogas slurry after anaerobic fermentation of wet garbage and wastewater from garbage transfer stations has also become one of the primary sources of landfill leachate. The water quality of leachate is very complex, contains high concentrations of pollutants, and is challenging to treat. With the continuous development of various technologies, leachate treatment technology has formed a diversified situation.

Nonwoven-Spunlace

The spun lace unit mainly comprises a water circulation system and a fiber mesh reinforcement system. The water circulation system mainly includes water filtration, pressurization, spun lace, recovery, and other devices. Filtration generally adopts multi-stage water filtration and applies different methods, and ultimately, impurities with diameters as small as 20 μm must be filtered out. Nowadays, the most mature method widely used and proven to be the best is air flotation + sand filtration + secondary filtration + safety filtration.

River and Lake

With the development of the industrialization era, chemical substances such as N and P are widely used. When they enter the water body, they will cause eutrophication of the water body, leading to the rapid growth of algae in the water body, resulting in black and odorous problems in rivers. This is also currently affecting urban rivers. Common pollution issues in water quality.
