### **Working Principle of Nanotechnology**
Nanotechnology in wastewater treatment is based on a self-cleaning principle that stimulates the growth of beneficial microorganisms while inhibiting harmful ones. This system efficiently removes organic matter, nitrogen-containing compounds, phosphorus, and suspended solids, ensuring wastewater meets safety standards before discharge.
Key advantages of nanotechnology include:
- **Increased oxygen concentration**: Nano bubbles saturated with oxygen improve water quality.
- **Support for microorganisms**: Higher oxygen levels help microorganisms break down organic matter faster.
- **Accelerated treatment**: Nano bubbles oxidize harmful bacteria and organic substances, shortening treatment time.
- **Removal of radioactivity**: Nanotechnology effectively removes radioactive wastewater, especially in aquaculture environments.
**Note:** Before applying the system, it's important to pre-filter the water to remove large debris, which enhances the system's performance.

### **Key Stages of Wastewater Treatment Using Nanotechnology**
The wastewater treatment process using nanotechnology consists of several stages, each playing a crucial role in improving water quality. Below are the main steps in the nanotechnology-based wastewater treatment process.
#### **Stage 1: Gas Diffusion**
In this stage, nano bubbles are diffused into the wastewater in a saturated form to increase dissolved oxygen. Compared to regular air bubbles, nano bubbles remain in the water longer, ensuring continuous oxygen supply. This oxygen supports the growth of aerobic bacteria, promoting the breakdown of organic pollutants.
#### **Stage 2: Biological Reaction**
Once the wastewater has sufficient oxygen, beneficial microorganisms are activated to degrade pollutants. Aerobic and anaerobic bacteria work together to convert complex organic compounds into simpler forms, reducing waste and odor.
At the same time, this process suppresses harmful microorganisms, ensuring efficient wastewater treatment and meeting environmental standards before discharge.
