1. AO industrial wastewater treatment technology

AO industrial park wastewater treatment technology is also known as anaerobic - anoxic - aerobic biotechnology. This technology applies the living activities of microorganisms in wastewater to treat and metabolize pollutants.

Characteristic:

• This is a traditional, popular wastewater treatment technology that is easy to operate and can be automated.
• Effective treatment of BOD, COD, nitrogen and phosphorus.
• Limit sludge, treat wastewater with high organic pollution load.

2. Physical and chemical wastewater treatment technology

Physicochemical wastewater treatment technology relies on chemical reactions and physicochemical processes taking place between pollutants and added chemicals. The reactions that take place in this process include oxidation and reduction, formation of precipitates and decomposition of toxic substances. The chemical methods are oxidation, neutralization and flocculation.

Characteristic:

• Applying this technology, a large amount of suspended solids will be removed along with nitrogen, phosphorus, heavy metals and microorganisms.
• In particular, physicochemical technology can also treat small colloidal pollutants in wastewater.

3. Biological treatment technology with MBBR mobile media

This is a technology that uses microorganisms to decompose organic matter by adding mobile substrates.

Characteristic:

Construction area and water retention time are less than traditional AO treatment technology.

4. MBR membrane biological treatment technology

MBR membrane biological treatment technology applies wastewater microbiology technology based on combining Aerotank suspended activated sludge settling tank and MBR membrane.

Accordingly, in the Aerotank gas will be continuously supplied to help microorganisms maintain life, grow and process organic substances. Sludge and organic matter produced during this process will be retained through the biofilm mechanism.

Characteristic:

• Applying microorganisms to decompose organic substances and supplement physical filtration membranes.
• Output water quality is considered much better than other technologies, almost meeting strict standards thanks to high-level suspended solids and microbiological removal performance.
• Treated water can be reused.
• The system is designed as an efficient module, minimizing the risk of clogging.
• The membrane body is coated with a polymer layer so it can limit damage when using chlorine to clean.
• Savings in construction costs, electricity, and excess sludge generated are also very little.
• The maintenance process is convenient and easy.

5. Batch biological treatment technology SBR/ ASBR

This is a wastewater treatment technology that uses microorganisms to decompose organic substances, the entire process occurs in only one tank. At the same time, wastewater is treated in batches.

Characteristic:

• This technology operates based on an automatic operating system.
• Minimize the equipment used in the settling tank and no need to circulate sludge.
