Hesaide is a complex environmental protection service provider of filter outfit production, filter technology overall plan solution and environment protection project contraction and operation.

Bio-pharmaceuticals:Fishery Industry

Bio-pharmaceuticals:Fishery Industry

Aquaculture wastewater in fishery industry comes mainly from excreta and undigested feed. This kind of wastewater belongs to low-concentration organic sewage. In order to fully treat and use the sewage, Hesaide membrane filter press will be your first choice. Membrane filter press can finish solid liquid separation and greatly reduce moisture of filter cakes. Then, you can make fermentation with filter cakes, so as to produce organic fertilizer.

Mining and Minerals Industry:Mining

Mining and Minerals Industry:Mining

Hesaide filter press is ideal equipment for dealing waste water in mining and minerals industry. Hesaide filter press is mainly used for dewatering fine coal and coal tailings. In addition, ore concentrate suspension concentrated by floatation and separated from mineral by-production can achieve solid liquid separation by BBNEP filter press. In this process, zinc, iron, copper and other metals will be extracted, while gold, silver, and platinum and other precious metals will be leaved in filter chamber in form of filter cakes. In terms of this industry, membrane filter press and chamber filter press with automatic plate shifter are recommend. They are featured with fast cycle time, high filtration speed, and lower water content of filter cakes and so on.

Metallurgical Electronics:Electroplating industry

Metallurgical Electronics:Electroplating industry

The primary source of zinc in wastewater from the electroplating and metal processing industries comes from drag-out solutions used in electroplating or pickling baths. During the rinsing process, these pollutants are transferred into the wastewater stream.  


The pickling process typically involves first immersing metals (such as zinc or copper) in strong acids to remove surface oxides, followed by treatment in brightening solutions containing chromic acid to enhance surface finish. The resulting wastewater contains high concentrations of hazardous substances, including hydrochloric acid, zinc, copper, and organic brighteners. These contaminants are highly toxic, with some even classified as carcinogenic, teratogenic, or mutagenic, posing severe risks to human health and the environment.  


Given the severe environmental and health hazards, electroplating wastewater must undergo thorough treatment and recycling to minimize or eliminate its harmful impact. Proper filtration and purification systems are essential to recover valuable metals and ensure compliance with environmental regulations.



Metallurgical Electronics:Steel industry

Metallurgical Electronics:Steel industry

In the wastewater treatment of the steel industry, filter presses are predominantly utilized. Industrial steel plants generate wastewater containing a substantial amount of high-hardness metal impurities and various chemical reagents, necessitating filter presses with excellent corrosion and wear resistance.  


During sludge dewatering, our company's filter presses can effectively control the moisture content of the filter cake within specified limits. This ensures compliance with sludge transportation requirements while preventing secondary pollution. Our equipment delivers reliable performance, meeting the stringent demands of steel industry wastewater treatment with high efficiency and durability.


Printing, Dyeing & Papermaking:Paper Making Industry

Printing, Dyeing & Papermaking:Paper Making Industry

During production process, papermaking industry produces a large amount of waste water. In order to effectively treat waste water and make it reach sewage discharged standard, Hesaide filter press may be a good choice. Adding chemical reagent and flocculating can accumulate separation between solid material and liquid. Meanwhile, filter press can make solid materials into filter cakes, and liquid can be discharged or recycled. Filter press can greatly reduce the difficulty of wastewater treatment.

Printing, Dyeing & Papermaking:Textile Industry

Printing, Dyeing & Papermaking:Textile Industry

In terms of sludge generated in textile industry, direct landfill may be the first choice. However, this method will cause secondary pollution and increase environmental stress. In order to deal with sewage well, filter press is recommended. Filter press can separate solid materials from liquid. In this way, you can recycle the filtered liquid, meanwhile, solid materials exist in form of filter cakes which will be more convenient for treatment.

Brewery and Fermentation:Beer Industry

Brewery and Fermentation:Beer Industry

In beer industry, filter press is mainly used for removing impurities and bacteria. In addition, it can effectively prevent nutrient loss, so as to keep wine fresh. With the help of pump, beer will enters filter press and finish filtration in the filter chamber. Filtered beer will be send to next steps. At the same time, impurities and solid materials will be leaved in filter chamber and form into filter cakes.
