Fixed Film Reactors (FFR), also known as attached biofilm reactors, supports the growth of beneficial microorganisms to break down pollutants. Wastewater is sprayed onto the media to grow the desired bacteria that consume pollutants.
High treatment efficiency is achieved as biofilm grows on media surfaces, providing a large active area for effective pollutant degradation.
Compact design allows the system to occupy significantly less space than traditional suspended-growth systems like activated sludge.
Stable operation is maintained as the biofilm structure protects microbes from shocks and fluctuations in flow or organic load.
Effective nutrient removal supports both nitrification and denitrification processes for nitrogen control.
Low sludge production results in reduced excess sludge volumes, lowering handling and disposal costs.
Adaptable to various wastewater types, this technology is well suited for municipal, industrial, and decentralized treatment.
Energy efficient performance is often achieved with reduced aeration demands and lower operational costs compared to conventional systems.
Fixed Film Reactors offer exceptional versatility, ideal for treating both domestic and industrial wastewater. They can operate efficiently under aerobic, anoxic, or anaerobic conditions, making them adaptable to a wide range of treatment needs. With lower energy consumption compared to other technologies, they also provide a more sustainable, cost-effective solution for long-term performance.
Applied for treating high-strength or variable load wastewater.
Used in small to mid-sized treatment plants for stable BOD and ammonia removal, especially where space or operator resources are limited.
Provides consistent, compact treatment for facilities with fluctuating occupancy and limited infrastructure.
Handles organic-rich effluents from seasonal operations with minimal operator oversight.
Nviro’s fixed film reactors are designed for stable, low-maintenance biological treatment in demanding conditions. Our systems use high-surface-area media to support dense biofilm growth, ensuring consistent performance even with variable loading or flow rates. Engineered in-house and built for durability, Nviro’s solutions are ideal for decentralized, industrial, and reuse applications, delivering reliable BOD and ammonia removal with simplified operation, minimal sludge production, and a compact footprint.
