Sludge dewatering - perfect assistant in industrial wastewater treatment

Industrial wastewater treatment is an urgent issue that needs serious attention today. Because Vietnam's economic structure is tending to shift strongly to industry. The amount of waste generated is increasing, challenging treatment systems. Innovation and improvement are urgent requirements.

In the industrial wastewater treatment process, the sludge press is an important piece of equipment. It plays a key role. It is an indispensable piece in the final stage of the process - the sludge treatment stage.

What is a standard industrial wastewater treatment system?

Industrial wastewater contains a multitude of different impurities, with diverse physicochemical properties. Includes: residues, suspended solids, organic matter, metals, nutrients, germs, and bacteria.

Industries that produce different products will emit wastewater of different properties. The composition of pollutants is also different. Industrial wastewater can be divided into 3 main groups including:

– Group 1:

Heavy metals and toxic chemicals: pulp production, bleaching, tanning, bleaching, dyeing, plating industries. Chemical manufacturing industries, battery manufacturing - accumulators, detergents, dyes, printing inks.

– Group 2:

Industry of manufacturing and processing monolithic wood, processing wood products. Steel rolling industry, products from steel billet. Industry producing artificial rubber products, food processing industry, seafood processing industry.

– Group 3:

The brick manufacturing industry, production of raw materials preparation and pesticides. Fertilizer production industry, scrap, and waste recycling industry, natural rubber latex preliminary processing industry. The animal feed industry, poultry, starch production from potatoes, cassava.

The standard industrial wastewater treatment system must be built based on the characteristics of the wastewater source. Also calculate factors such as:

  • processing capacity,
  • water quality after treatment,
  • scale of the industrial production.
  • Finally, the future development plan of the factory and industrial park.

In general, a professional industrial wastewater treatment system must have a full range of items. Consists of:

  • sewage collection tank,
  • conditioning tank,
  • flocculation tank,
  • settling tank,
  • disinfection tank,
  • sludge tank, …

Attached are auxiliary equipment such as: garbage filter, stirrer, metal filter in storage tanks, sludge treatment chemicals, coagulants, flocculation, polymer...

Where is the sludge press in a standard industrial wastewater treatment system?

In a standard industrial wastewater treatment process, the sludge must go through many treatment stages. Including many different physicochemical tanks, BOD, COD. The sludge generated at each stage will be the raw material for the next work. Finally, the sludge is collected and concentrated in the sludge storage tank.

In this final stage, the sludge will have to be converted from liquid to solid. From containing many hazardous chemicals to minimizing environmental pollution. To minimize the volume and weight of the sludge solution, the most optimal way is using a sludge press.

Waste sludge before being put into the press may / or may not need to undergo flocculation treatment and concentration of the sludge solution first. Depending on the characteristics of each type of sludge press. The sludge after being pressed will certainly reduce the water content, thereby drying, the volume and weight will decrease significantly.

Benefits of sludge dewatering machine in industrial wastewater treatment

In particular, ARK Vietnam's new generation of advanced sludge presses are manufactured according to Korean standards, such as decanter centrifuge, screw press, which are extremely effective in dewatering, work continuously. The treated dry sludge has high looseness, and stability.

The feature of the sludge dewatering machine is to separate the sewage and solids contained in the sludge. Pressed sludge will significantly reduce the initial odor. Especially not polluting the environment. Convenient for later processing or disposal.

Discharged water is also significantly reduced unpleasant odors. Especially, the amount of dissolved solids is greatly reduced. If adjusted properly, the filtered water has impressive clarity. However, excess solute, as well as polymer content, still remains in the water. But the next processing stage will not be too complicated.

Conclusion

To build a professional and standard industrial wastewater treatment system, the sludge press is a key component. Depending on the application technology and capacity of the machine, the initial investment to equip the machine may not be small. Definitely disturbing investors, with many question marks about product quality.

But we can assure you, sludge presses are effective industrial devices. They help factories and enterprises save significant costs on labor and costs in the process of sludge treatment. Economic benefits are long-term and will bring profits to customers.

 

All stages of production, processing and set up are extremely meticulous, strictly under ISO standards
