Biological water treatment
Custom-engineered wastewater solutions
Biological water treatment forms the core of a reliable treatment solution. Since industrial wastewater streams vary significantly by industry and load, we design the installation that delivers both technically and economically optimal results for your facility.
High removal capacity, guaranteed compliance
Our biological systems achieve reliable reduction of COD, BOD, nitrogen and phosphorus, ensuring you safely meet all regulatory requirements without risk of exceedances.
Robust, flexible and integrated
Strong process management and intelligent control systems handle peak loads, while seamless integration with upstream screening, precipitation and downstream membrane and sludge dewatering systems ensures complete system control.
Benefits of Morselt Biological water treatment
- Custom system engineering: Targeted selection and dimensioning of the biological process, tuned to your specific effluent values and discharge limits.
- High removal capacity: Reliable reduction of biodegradable substances (COD, BOD, nitrogen, phosphorus) for regulatory compliance.
- Maximum operational reliability: Robust process management and intelligent control handle fluctuations in wastewater concentration and peak loads.
- Integrated system integration: Seamlessly combines with upstream and downstream treatment stages in one coordinated system.
- Energy-optimized aeration technology: Highly efficient compressors and aeration elements keep operating costs low.
- Smart process automation: Fully automatic PLC control with remote maintenance capabilities, nutrient dosing and continuous measurement and control technology.
Technical specifications (standard)
- Material selection: Stainless steel (V2A/V4A), coated steel or PE/PP, matched to your wastewater type.
- Operating principle: Biological degradation by microorganisms; conversion of organic contaminants to biomass (sludge), water and CO2.
- Process options: Aerobic (aerated) or anaerobic systems, depending on wastewater composition.
- Measurement and control technology: Intelligent M&C technology for stable and reliable biological degradation.
- Pre-treatment: Integrable with chemical precipitation, flocculation or electrocoagulation for recalcitrant substances.
Configurations and options
Membrane bioreactor (MBR)
Combination of biological degradation with downstream ultrafiltration. This delivers pathogen- and suspended solids-free water that can be directly reused as process water. No secondary clarifier needed, optimal for maximum water quality.
Moving Bed Biofilm Reactor (MBBR)
Microorganisms grow on special plastic carrier media that move freely in the reactor. This delivers very high biomass concentration in a small footprint and is ideal for capacity upgrades of existing systems.
SBR process (Sequencing Batch Reactor)
Biological degradation, sedimentation and water discharge occur sequentially in the same reactor basin. This process is highly flexible for variable inlet flows, requires minimal space and is economically advantageous.
Fixed-bed and activated sludge systems
Continuous flow through aerated basins with fixed carrier elements or freely suspended biomass. A very economical basic solution for continuous operation with reliable loads in wastewater treatment.
