Operational challenges at wastewater treatment plants
Problems it solves
Oblysis® is designed to address the key operational challenges faced by today’s wastewater treatment plants, improving biological process performance without construction work, structural expansions or interrupting plant operations.
Overloaded plant
It helps increase the treatment capacity of existing facilities, enabling them to achieve higher performance without the need for major expansions.
Poor biological performance
Promotes the transformation of biomass into a more efficient, stable and resilient hybrid granular sludge.
Poor sludge settleability
Improves sludge performance in the process, reducing issues associated with suspended solids and effluent quality loss.
Limited nutrient removal
Helps improve biological nitrogen and phosphorus removal, supporting compliance with more stringent quality targets.
High operating costs
Reduces energy consumption, sludge production and chemical use, optimising WWTP operating costs.
High sludge production
Reduces secondary sludge generation, lowering the costs associated with its management, treatment and removal.
Unstable processes
Provides greater stability to the biological system in response to load variations, operational changes or periods of stress at the plant.
Need to improve without shutting down the plant
It is quick and non-intrusive to implement, with no tank emptying, plant shutdowns or structural modifications.

What is Oblysis®?
Oblysis® is an integrated technology that combines a physical device and advanced digital control to transform biomass into more efficient, stable, and optimized biological systems.
Its application in existing activated sludge plants enables direct intervention in the biological process, improving overall WWTP performance without the need for major structural work.
Hardware device
The hardware component consists of a floating device installed in the oxidation tank, allowing mixed liquor to flow through it during the process.
This device incorporates a range of functional components that provide the necessary impetus to the biomass, encouraging it to transform into more efficient and resilient forms.
Control Software
The system intelligently manages aeration, mixing and internal recirculation in the biological reactor by controlling blowers, mixers and recirculation pumps.
Its objective is to maintain optimal operating conditions, enabling controlled biomass transformation within the reactor and continuous process improvement.
The combination of specialized hardware and control software can transform existing plants into more efficient biological systems, with more stable, optimized operations focused on measurable results.
How Oblysis® works
Oblysis® combines physical technology and intelligent control to transform the biological performance of existing treatment plants.
The solution combines a floating stainless-steel device installed in the biological reactor with an advanced software platform that adjusts system operation to the plant’s actual conditions.
1
Installation in the biological reactor
The Oblysis® device is installed directly in the heart of the biological process, with no need for structural work or major modifications to the existing facility.
Its integration allows the biomass to be treated within the system itself while maintaining uninterrupted plant operations.
2
Natural biomass transformation
Once operational, Oblysis® promotes the formation of hybrid granular biomass, combining the advantages of granular and flocculent sludge.
This transformation improves biological process performance and delivers a more efficient, stable system that is better equipped to meet more demanding operating requirements.
3
Intelligent process control
The software platform intelligently manages key parameters such as aeration and system operating conditions.
Thanks to adaptive algorithms, the system adjusts to changes in flow, pollutant load and environmental conditions, optimising plant operation in real time.
4
Improved operational performance
The combination of a physical device, hybrid granular biomass and advanced control improves settleability, increases treatment capacity and optimises nutrient removal.
The result is a more efficient WWTP, with greater operational stability and improved performance, without the need for major structural work.
5
Monitoring and continuous improvement
Oblysis® is not a standalone solution, but a system designed for continuous process monitoring.
Daily operations, monitoring, and parameter adjustments help maintain performance over time and adapt operations to the actual needs of each facility.
Hybrid granular biomass
Sludge as a driver of WWTP efficiency
Oblysis® promotes the transformation of biomass in the biological reactor into a more efficient, stable and resilient hybrid granular sludge. This evolution improves settleability, reduces sludge production and helps optimise the plant’s overall performance without structural modifications.
