1
Preliminary screening
Retains solid waste and fish residue, protects internal equipment, and ensures smooth flow through the station.
Our services and warranty
From the technical study to commissioning, OUAFI Solutions designs, manufactures and installs HYDROFORT DAF treatment plants 100% tailored to fish processing factories.
How the HYDROFORT DAF plant works
Wastewater moves through fully automated technical stages; human intervention is limited to simple, periodic service monitoring:
2
Homogenization basin aeration
Homogenizes stored wastewater and prevents anaerobic reactions and sudden fermentation in the primary tank.
3
DAF unit – dissolved air flotation
Injects air-saturated water to form micro-bubbles that remove grease, oils, and suspended matter with high efficiency.
4
Biological treatment
Treats dissolved organic matter; activated and customized based on factory needs and local environmental authority requirements.
5
Sludge filtration
Compresses and dries sludge; with the Hydro Presse filter, filter changes take just ten seconds with no downtime.
Human operation: the station runs fully automatically; human involvement is limited to adding chemicals to adjust pH (after the station's automatic alarm) and monitoring/emptying the dry sludge container once full.
Our solutions
1
Water recycling for reuse
Optional add-on: recycling treated water from an additional stage for washing yards and disinfecting fish transport crates, cutting the water bill.
2
Reduced footprint
The Hydrofort DAF only occupies 75% of the usual floor space thanks to smart engineering, offering flexibility for factories with limited space.
3
Spare parts available instantly
100% local manufacturing: spare parts and technical support are available immediately, with no import delays or extra costs.
4
Robust classic automation
Sensitive electronic boards are replaced with rugged classic automated controllers built to withstand high humidity and salinity in fish factories.
5
A genuinely profitable investment
Sludge drying reduces waste volume and transport costs by up to 80%, with the option to resell it as fertilizer.
6
Guaranteed regulatory compliance
Full engineering support from the blueprints to lab analysis, ensuring treated water fully complies with national standards.
7
Sustainable operational stability
Preliminary screening and advanced tank aeration prevent anaerobic fermentation and maintain a continuous, homogeneous flow.
