SUSBIO ECOTREAT Process: A Step-by-Step Breakdown

SUSBIO ECOTREAT integrates advanced treatment technologies in a compact and modular system, making it highly efficient and user-friendly. Here’s how it works:

1. Primary Treatment (Physical Screening and Settling):

   • Wastewater first enters the primary treatment chamber, where large solids, debris, and non-biodegradable materials are filtered out using fine screens.
   • Heavier particles settle at the bottom, while lighter particles float to the surface, ensuring the wastewater is pretreated before moving to the biological treatment stage.

2. Biological Treatment (Dual-Stage Process):

   • The first stage uses aerobic biological treatment, where oxygen is supplied to microorganisms that break down organic matter in the wastewater. This step is critical for reducing COD and BOD levels.
   • The second stage involves a fixed biofilm process, where bacteria attached to specially designed media further digest organic matter. This ensures maximum efficiency in removing impurities.

3. Secondary Clarification (Sludge Separation):

   • Treated water from the biological stage flows into a clarifier, where suspended solids and biomass settle to the bottom. The clarified water, now free of most impurities, is separated from the sludge.

4. Tertiary Treatment (Advanced Filtration):

   • The water undergoes tertiary treatment using advanced filtration technologies such as sand filters or activated carbon filters. This step ensures the treated water meets the highest standards for reuse or safe disposal.

5. Disinfection:

   • In the final stage, the water is disinfected using methods like UV treatment or chlorination, eliminating any remaining pathogens. The result is clean, odor-free water that can be reused for landscaping, irrigation, or other non-potable purposes.

6. Sludge Management:

   • The sludge generated during the treatment process is collected in a separate chamber. It is treated and dewatered for safe disposal or used as fertilizer, making the system environmentally sustainable.
