Operation Mechanism of Wastewater Treatment Module Using MBR Technology from WeMe

Technology Diagram Explanation

Collection Pit:

Wastewater, after being separated from trash, grease, and oil, is collected in the pit before being sent to the treatment system. This separation helps to remove large debris like plastic bags, paper, leaves, glass shards, and gravel to avoid clogging pipes and pumps during operation and protect mechanical equipment from wear and tear.

Equalization Tank:

Air is supplied to stir the wastewater, preventing sedimentation and anaerobic decomposition, which can cause odors. The tank stabilizes the concentration and flow rate of the wastewater. The wastewater is then pumped into the anoxic tank.

Anoxic Tank:

Phosphorus is converted and NO3- is reduced to N2 gas, which escapes into the atmosphere. The concentration of P and N in the wastewater is reduced to allowable levels. The wastewater then flows into the aeration tank.

Aeration Tank:

Organic matter is removed through the activity of aerobic microorganisms, which use organic compounds in the wastewater as a food source to grow and multiply. These compounds are broken down into simpler substances. Air is continuously supplied through blowers and diffusers installed at the bottom of the tank.

MBR Module:

This consists of flat, parallel filter membranes submerged in the aeration tank. Aerobic treatment continues here. The MBR membrane, with microfiltration size, retains sludge, microorganisms, and suspended solids, allowing only clean water to pass through.

The treated water meets the required standards by the Ministry of Natural Resources and Environment for discharge into receiving sources after passing through WeMe’s MBR wastewater treatment technology.

Special Features of WeMe’s Wastewater Treatment Module

While MBR technology offers high treatment efficiency, membrane clogging can occur, reducing treatment performance due to dirt accumulation on the membrane surface. Understanding this, WeMe has integrated an automatic membrane cleaning mechanism into the module.

Specifically, after a period of operation (usually several hours), the system will stop to backwash the MBR membrane for about 5 minutes. During this time, water, along with chlorine bleach, is introduced into the module for cleaning through dosing pumps and a cleaning pump mounted on the module. Additionally, during operation, air blowers provide airflow to dislodge accumulated dirt on the membrane, ensuring smooth operation and maximum treatment efficiency.

Classification and Characteristics of Different Types of Wastewater

Classification of Wastewater

Based on the source of origin, wastewater is divided into the following main types:

• Domestic wastewater: Wastewater from the daily activities of households and service business establishments (restaurants, hotels, tourist areas, etc.).
• Industrial wastewater: Wastewater generated from the operations and production processes of factories and enterprises in the industrial sector.
• Agricultural wastewater: Wastewater generated from activities such as farming, cultivation, and livestock.
• Medical wastewater: Wastewater from medical establishments such as hospitals, clinics, and pharmaceutical manufacturing facilities.

Analysis of the Characteristics of Each Type of Wastewater

No.	Type of Wastewater	Characteristics	Discharge Standard
1	Domestic wastewater	Organic matter (BOD, COD), nutrients (N, P,..), pathogenic microorganisms	QCVN 14:2008/BTNMT
2	Industrial wastewater	Depends on the production type: organic pollution, oil, grease, heavy metals,…	QCVN 40:2011/BTNMT
3	Agricultural wastewater	Contains residues of pesticides, fertilizers, organic matter, pathogenic microorganisms,…	QCVN 62-MT:2016/BTNMT
4	Medical wastewater	Suspended solids, organic matter, pathogenic microorganisms, pharmaceutical residues,…	QCVN 28:2010/BTNMT
5	Food wastewater	Organic and inorganic substances, microorganisms: viruses, bacteria (some of which are non-harmful), BOD, COD, N, P	QCVN 40:2011/BTNMT

It can be seen that each type of wastewater has different pollution loads and discharge flows. They also have their own discharge standards, requiring facilities to treat them before discharging into the environment. Understanding the characteristics of each type of wastewater helps apply the wastewater treatment module effectively to achieve higher treatment efficiency.

Overview of Treatment Technologies for Various Types of Wastewater

In general, for each type of wastewater, pollution indicators such as organic and inorganic pollution, suspended solids, heavy metals, and pathogenic microorganisms vary. However, wastewater treatment systems generally follow similar processes, including:

• Mechanical Treatment: Removes coarse debris, insoluble substances, and large sediments (e.g., screening, oil skimming, sand settling tanks).
• Physicochemical Treatment: Removes small suspended particles that are difficult to settle from the water (e.g., coagulation-flocculation tanks).
• Biological Treatment: Uses the activity of microorganisms to treat organic pollution and nutrients (e.g., UASB tanks, anoxic tanks, aerotanks).
• Wastewater Disinfection: Removes pathogenic microorganisms (e.g., disinfection tanks).

Depending on the type of production, pollution load, and discharge flow, investors can choose the appropriate treatment technology, build the system, or install wastewater treatment modules for the best efficiency.
