At KLINGER Portugal, we offer a complete LiberAqua range of wastewater treatment equipment, designed to ensure high operational efficiency, low energy consumption, and full environmental compliance.
Our solutions cover all stages of the treatment process: pre-treatment, homogenization, primary, secondary, tertiary treatment, and sludge treatment.
Pre-Treatment
Equipment designed to remove coarse solids, sand, and fats, preventing clogging, mechanical wear, and performance loss in downstream equipment.
Available equipment:
- Vertical screens for coarse solids removal
- Internal and external feed rotary drum screens
- Combined equipment for sand and oil removal
- Self-cleaning disc filters (Wave Separator)
Homogenization
Homogenization solutions for equalizing flow and organic load, ensuring operational stability and efficiency in subsequent processes.
Available equipment:
- Modular tanks
- Welded steel tanks
- Concrete tanks
- Mixing and aeration systems (submersible or surface)

Primary Treatment
Physico-chemical clarification systems for removal of solids, oil & grease (O&G), and fine particles, ensuring high efficiency in coagulation/flocculation, flotation, or sedimentation.
Available equipment:
- Dissolved air flotation (DAF) units
- Clarifiers / Sedimentation units
- Wave Separator
- Automatic flocculant preparation units
- Chemical dosing skids
Secondary Treatment
Aeration systems for biological processes, ensuring high oxygen transfer efficiency.
Available equipment:
- Fine and coarse bubble diffusers
- High-speed mechanical surface aerators
- Low-speed mechanical surface aerators

Tertiary Treatment
Equipment designed to achieve high-quality treated water suitable for reuse and ensuring strict compliance with environmental standards.
Available equipment:
- Ozonation systems
- Ultrafiltration units
- Reverse osmosis units
Sludge Treatment
Equipment for efficient sludge thickening and dewatering, minimizing transportation and disposal costs.
Available equipment:
- Sludge thickeners with Wave Separator
- LDP sludge dewatering units
- Pumping and transfer systems

At KLINGER Portugal, we ensure the selection of the most suitable equipment for each application, delivering robust, compact solutions designed for continuous operation in demanding environments.
