Techniques

Chapter 1: Techniques

Anaerobic Digestion: The Heart of STAR

At the core of ADI Systems' STAR technology lies anaerobic digestion, a natural process where microorganisms break down organic matter in the absence of oxygen. This process is fundamental to the system's efficiency and sustainability.

Key Techniques Employed:

• Hydrolysis: Complex organic molecules are broken down into simpler sugars and fatty acids.
• Acidogenesis: These simpler molecules are further broken down by acid-forming bacteria, producing volatile fatty acids.
• Methanogenesis: Methanogenic bacteria convert volatile fatty acids into methane (CH4), carbon dioxide (CO2), and other byproducts.

Advantages of Anaerobic Digestion:

• Energy Recovery: Methane gas produced can be used to generate electricity or heat, offsetting operational costs and reducing dependence on fossil fuels.
• Sludge Reduction: The volume of sludge is significantly reduced, minimizing disposal costs and environmental impact.
• Nutrient Removal: Anaerobic digestion effectively removes nitrogen and phosphorus from wastewater, improving effluent quality.

Beyond Traditional Anaerobic Digestion:

ADI Systems' STAR technology goes beyond conventional anaerobic digestion by incorporating:

• Advanced Digester Design: Optimizing biogas production and sludge reduction through innovative reactor configurations and mixing techniques.
• Pre-Treatment Processes: Effectively removing solids and other inhibitors that can hinder anaerobic digestion.
• Post-Treatment Processes: Ensuring high-quality effluent by removing residual pollutants and maximizing nutrient recovery.
