Denitrifying Wastewater Treatment Plant - DSAF

The Denitrifying Wastewater Treatment Plant (DSAF) brings together proven wastewater treatment processes with Premier Tech Aqua UK’s in-house engineering expertise.


A robust and reliable solution, all DSAFs are designed and manufactured in the UK in accordance with EN 12566-3, the British Water Code of Practice for Flows and Loads. Made from Glass Reinforced Plastic (GRP), the DSAF is supplied with pedestrian duty covers and access manways as standard.


Reinforced, additional strength is provided via the bespoke design of the liner.
The adaptable design offers the flexibility of pumped influent or effluent, deeper inverts and high nitrification options and locations where the effluent cannot gravitate away. 

Typical applications include:

  • Hotels 
  • Leisure Parks 
  • Small communities or developments 


Lower Maintenance

The DSAF has optimised sludge accommodation in the tank for minimized desludging and has prespecified sludge volumes for precise emptying.

Energy Saving

Optimised oxygen input for reduced aeration costs and includes variable speed blowers for cost efficiency over the life of the product.


Superior Technical Performance

Tailored to meet the needs of the individual customer, the DSAF configuration offers 5mg/L of ammonia (NH3) as standard and improved Biochemical oxygen demand (BOD), Nitrogen (N) and Suspended Solids (SS) quality.




World leader in onsite and decentralized wastewater treatment, water storage and rain water harvesting solutions, Premier Tech Aqua specializes in the design and manufacturing of innovative and durable solutions.
