Fluence SUBRE - Upgrade Wastewater Treatment Plants
From Wastewater Treatment Products
Upgrade Wastewater Treatment Plants with SUBRE; With increased urbanization, wastewater resource recovery facilities face new challenges. When a conventional activated sludge wastewater treatment facility has reached its limit, Fluence's SUBRE can come to the rescue. Instead of enlarging current plants and building new basins, SUBRE modules are submerged in existing chambers, improving effluent quality, lowering the use of chemicals, saving energy and operational costs, and enlarging capacity. SUBRE upgrades WWTPs using membrane aerated biofilm reactor (MABR) modules. SUBRE is designed to upgrade existing basins with capacities of 2,000-100,000 m3/d (0.5-25 MGD) or improve effluent qualities to meet stringent nutrient regulations.

Product Details
SUBRE enables:
- Increased treatment capacity to accommodate higher inflows
- Reduced TN and TP in effluent water (biological nutrients removal)
- Progress toward energy-neutral treatment
In a SUBRE upgrade, The SUBRE modules containing up to 4 levels of MABR spirals are submerged in the anoxic zone of the WWTP (in a fully aerated reactor with no anoxic zone, construction of a separating wall will be required).
Easy-to-install MABR modules are energy-efficient and cost-effective, and ensure high effluent quality due to simultaneous nutrients revmoal. The SUBRE modules are suitable for installation in basin depths ranging from 1.5 m to 6 m (5-20 feet). The modules are anchored to the basin floor and are aerated by a separate low-pressure low-flow blower. Coarse bubble diffusers are used for periodic mixing of the suspended biomass (utilizing existing aeration blowers if possible).
The retrofit can be performed with minimal interruption, one basin at a time. Results seen in one to three weeks include an improved effluent quality and up to a 30% decrease in the plant's overall energy use. And, SUBRE will greatly save on operational expenses.
The SUBRE upgrade will achieve
- Enhanced Nitrogen removal
- Enhanced Bio-Phosphorous removal
- Increased capacity
- Improved effluent quality
- Decrease operational costs by up to 30%.
MABR Modules outperform attached growth solutions such as MBBR and IFAS with:
- Higher nitrification rate achieved in a once-through process
- Enhanced Biological Phosphorus removal
- Reduced energy costs
- Lower chemicals usage.
Product Overview:
SUBRE is a highly effective upgrade solution for wastewater treatment plants. SUBRE intensifies the biological nutrient removal process and increases plant's capacity with no added footprint and reduced energy requirements. SUBRE utilizes Fluence’s Membrane Aerated Biofilm Reactor (MABR) technology to achieve a stable and high quality effluent.
Upgrade Project Includes
- Retrofit of capacity ranging from 2,000-100,000 mVday
- Installation in an existing anoxic basin (if necessary, a separation baffle will be built)
- Utilizes existing aeration system
- Eliminates internal nitrates circulation
- Fast and easy installation with immediate results

Fluence Launches Energy Consumption Calculator for Wastewater Treatment Based on International Standard
In the past, there was no single trusted way for engineering consultants and utility owners to compare energy efficiency claims by various wastewater treatment manufacturers. Traditional measurement methods focused on different parameters and expressed energy in different formats leading to unreliable and inconsistent results. To solve this problem, experts created the ISO 21939-1:2019 standard, a standardized means to express energy consumption for biological wastewater treatment processes. This method accounts...
