2. How with the increase in volume of wastewater , TDS and EC will increase after microbial fuel cell treatment in water?
Thank you for your time and expertise.
Microbial fuel cells (MFCs) are a promising technology for wastewater treatment, which leverages the metabolic activity of microorganisms to break down organic pollutants and generate electricity. Here are some key aspects of wastewater treatment through MFCs:
1. Principle: MFCs use microorganisms to oxidize organic matter in wastewater, producing electrons that flow through an external circuit, generating electricity.
2. Advantages:
- Simultaneous wastewater treatment and energy generation
- Low energy requirements
- Potential for high organic removal efficiency
- Compact and modular design
3. Challenges:
- Scalability and cost-effectiveness
- Electrode material selection and durability
- Microbial community management and stability
- System optimization and control
4. Types of MFCs:
- Single-chamber MFCs
- Dual-chamber MFCs
- Upflow MFCs
- Downflow MFCs
MFCs use the bio electrochemical activity of microbes to oxidize organic and inorganic substrates in wastewater, producing electricity. MFCs can be used in decentralized wastewater treatment systems, making them applicable to areas that lack electricity. The microorganisms in wastewater can also self-generate, so there's no need to periodically add bacteria to the MFCs. aerobic bacteria, act as biochemical surgeons, targeting and reducing the biochemical oxygen demand in wastewater. This reduction is crucial in preventing oxygen depletion in water bodies and safeguarding aquatic ecosystems. MFCs are used in water treatment to harvest energy utilizing anaerobic digestion. The process can also reduce pathogens. However, it requires temperatures upwards of 30 degrees C and requires an extra step in order to convert biogas to electricity. Spiral spacers may be used to increase electricity generation by creating a helical flow in the MFC. Scaling MFCs is a challenge because of the power output challenges of a larger surface area.

An increase in the volume of wastewater may lead to a rise in Electrical Conductivity (EC) after Microbial Fuel Cell (MFC) treatment. This is primarily due to the accumulation of ions remaining from the treatment process and potential improvements in ion removal efficiency. The design of the MFC, the properties of the wastewater, and the operating conditions all play a role in this relationship. A higher volume of wastewater may contain more dissolved ions, such as salts, nutrients, and other ionic substances. If the microbial fuel cell does not entirely remove these ions, they will remain in the treated water, causing an increase in EC.
