Revolutionizing Wastewater Treatment: CACCO Technology in STP at SRMIST

 Revolutionizing Wastewater Treatment: CACCO Technology in STP at SRMIST

At SRM Institute of Science and Technology (SRMIST), our commitment to sustainable campus operations is strengthened with the installation of a new 600 KLD Sewage Treatment Plant (STP) near the Dental College, utilizing advanced CACCO Technology.

This cutting-edge system ensures efficient, low-energy, and eco-friendly wastewater treatment, aligning with SRMIST’s green campus goals and global best practices for water reuse and environmental protection.

🌿 New 600 KLD STP at SRMIST Dental College

SRMIST has commissioned a new STP with a capacity of 600 KLD near the Dental College to manage and treat sewage effectively while supporting water conservation and reuse on campus. This plant adopts CACCO Technology for enhanced treatment efficiency, reduced sludge generation, and improved treated water quality for campus reuse.

What is CACCO Technology?

CACCO (Catalytic and Chemo Autotrophic Cermet Catalyst Oxidation) Technology combines immobilized bacteria with advanced catalytic processes to degrade organics and pathogens efficiently in wastewater. The system includes:

• SOAR Reactor

• FICCO Reactor

• CAACO Reactor

Each stage ensures a multi-layered, high-efficiency treatment with minimal energy usage.

1️⃣ SOAR Reactor: Simplified, Power-Free Treatment

A three-chamber Oxic-Anoxic system using bio media for attached growth without power or moving parts:

• Baffles enhance treatment efficiency.

• Sludge is mineralized and can be used as manure.

• Oxic zone sludge is recycled to improve system efficiency.

---

2️⃣ FICCO Reactor: Advanced Reduction of BOD, COD, TSS

Features:
✅ Nanoporous Activated Cermet Catalyst with immobilized chemo autotrophic bacteria.
✅ Low-pressure air fluidization (0.6 kg/cm²).
✅ Significant reduction in BOD, COD, and TSS.
✅ Biomass recycling for sustainability.

---

3️⃣ CAACO Reactor: Deep Polishing of Water

A tall packed-bed reactor providing:

• Further reduction of residual COD, BOD, and sulphides not removed by conventional methods.

• Treated water is passed through Ultra Filtration (UF) for further polishing, followed by ozonation, making it fit for cooling tower reuse on campus.

---

Why is the Immobilized System Highly Efficient?

✅ Immobilized bacteria within the carbon matrix prevent oxygen dissipation.
✅ Enhanced enzyme-substrate interaction speeds pollutant degradation.
✅ Low-yield bacteria reduce biomass production.
✅ Hydroxyl radicals (ORP 2.80V) provide powerful catalytic and biological oxidation.
✅ Constant active sites ensure steady pollutant removal.
✅ Eliminates bacterial genes, preventing regrowth in treated water.
