We are excited to share the latest progress on our 3000 m³/d DAF system for the Uzbekistan project. Following the successful shipment on March 12, 2026 (covered in our previous post), our technical team has now completed on‑site installation and has moved into the field commissioning and testing phase.
The dissolved air flotation (DAF) unit is now running with real industrial wastewater, delivering stable performance under full operating conditions. This milestone marks a critical step toward final handover and demonstrates the reliability of our equipment in a challenging field environment.
On‑site commissioning highlights:
Full‑scale bubble generation – The DAF system produces consistent microbubbles, effectively floating suspended solids, oils, and grease to the surface. Visual inspection confirms even distribution across the entire tank width.
Automated skimming operation – The stainless steel chain skimmer (upgraded from standard ABS) operates smoothly, removing floated sludge without interruption. The sludge discharge is dry and manageable.
Control system validation – The PLC panel (with optional Schneider components) has been tested under varying flow rates. All alarms, dosing pumps, and pressure sensors respond correctly, ensuring unattended operation is safe and reliable.
Effluent quality – Preliminary sampling shows suspended solids below 30 mg/L and oil/grease under 5 mg/L, already meeting local discharge limits. Further tuning will improve performance.
Why this DAF system stands out for Uzbekistan:
✅ Corrosion‑resistant materials – The tank and all wetted parts are stainless steel, suitable for local industrial wastewater with variable pH.
✅ Energy‑efficient design – The recirculation pump and air dissolution system consume 15% less power than conventional units.
✅ Low maintenance – The stainless steel chain drive eliminates wear issues common with ABS chains, reducing downtime.
✅ Fast commissioning – Our modular design allowed the local team to complete piping and electrical connections in just five days.
Linking back to our previous article:
As announced on March 12, 2026, the system was shipped in six reinforced crates. You can read the original shipment announcement here: [Insert link to previous Uzbekistan DAF article]. Now, with commissioning underway, the client is already planning to expand the pretreatment line with a second DAF unit later this year.
The Uzbekistan project is a perfect example of how our DAF technology solves real‑world industrial wastewater challenges. We will continue to share updates as we move toward final performance testing and client acceptance.
