IFAS MBBR Hybrid Retrofit System with 50 - 200% Capacity Increase and HDPE K1 K5 Biofilm Carriers for Minimal Downtime Upgrades

IFAS MBBR Hybrid Retrofit System for Latin American Activated Sludge Plant Upgrades

Our IFAS MBBR Hybrid Retrofit System (Model BM-IFAS-RK) is a complete upgrade kit that converts conventional activated sludge wastewater treatment plants into high-capacity Integrated Fixed-Film Activated Sludge (IFAS) or MBBR systems. Designed for municipal and industrial plant operators across Latin America, this wastewater treatment filter media retrofit solution doubles biological treatment capacity without requiring additional tank construction, saving 40–60% in capital expenditure compared to greenfield expansion.

Maximize Existing Infrastructure with IFAS MBBR Retrofit

• Double Capacity Without Construction: By introducing wastewater treatment filter media biofilm carriers into existing aeration basins, the hybrid IFAS process achieves 3–5 times higher biomass concentration than suspended-growth alone. Plants treating 5,000 m³/d can be upgraded to 10,000 m³/d within the same tank volume, critical for space-constrained urban facilities in São Paulo, Mexico City, Bogotá, and Lima.
• Phased Commissioning for Uninterrupted Operation: The retrofit kit is designed for staged implementation. Individual treatment lanes can be taken offline sequentially while others remain in service, eliminating the need for plant shutdown. This is essential for municipal utilities serving populations that cannot tolerate service interruption.
• Complete Retrofit Package: Each BM-IFAS-RK includes pre-calculated HDPE biofilm carriers (K1 and K5 mix optimized for influent characteristics), SS304 wedge wire retention screens with mounting frames, aeration grid modification components (fine bubble diffusers, air piping, blower rebalancing guide), and detailed engineering drawings stamped for local permitting.
• Financing-Ready Documentation: Complete technical package aligned with development bank procurement requirements (IDB, CAF, World Bank). Includes lifecycle cost analysis, energy savings projections, and reference case studies from operational IFAS retrofits at municipal plants in Brazil and Mexico.
• Latin American Regulatory Compliance: Pre-engineered to meet CONAMA 430 (Brazil), NOM-001-SEMARNAT (Mexico), Resolución 0631 (Colombia), and DS 90 (Chile) discharge standards. All documentation, training materials, and O&M manuals provided in Spanish and Portuguese.

Proven IFAS Retrofits in Latin America

DUBHE IFAS MBBR retrofit systems have successfully upgraded municipal wastewater treatment plants in Campinas and Curitiba, Brazil, industrial park treatment in León, Mexico, food processing wastewater facility in Cali, Colombia, and textile treatment plant in Lima, Peru. Each retrofit achieved design treatment capacity within 4–6 weeks of commissioning with stable nitrification even under diurnal flow variations.
