Project’s context & challenges

Australis Seafoods, a leading salmon producer in Chile, is committed to sustainable aquaculture and responsible water management. To meet strict local and international discharge regulations, the company partnered with Nijhuis Saur Industries (NSI), part of Saur Group, to develop a modular and efficient wastewater treatment solution tailored to the fish processing industry.

Meet local and international regulations
To meet local and international discharge regulations of wastewater effluent, Australis was looking for a reliable water treatment plant supplier with the right fish industry expertise.

Modular and flexible was needed
Due to the mixed wastewater influent characteristics and the dynamic water flows, a modular and flexible needed to be implemented.

Key figures

Industry:
Fish processing
1,200 m3 / 317,000 gallons
Flow per day
"Thanks to the high-performance wastewater treatment plant from Nijhuis Saur Industries, we operate with a very good cost-efficiency ratio for discharge and fully comply with the regulations required by regulatory bodies. The smooth cooperation between our companies ensured an efficient process for discharging clean effluent, even exceeding local standards and improving water quality. "

Reliability of solution proposed.

Solution

We implemented a multi-stage water treatment system to reduce pollution and enhance sustainability. Wastewater first passes through a filter, removing solids before entering a balance tank for flow stabilization. Flocculation and flotation separate fine particles. A biological treatment solution with an activated sludge DAF acts as an optional step when additional pollution must be removed to meet the discharge limits.

Finally, sludge from the pre treatment DAF is dewatered using a screw press, minimizing sludge disposal. This system significantly reduces discharge cost and improves water quality.

Scope of supply

  • Contract type: Design, supply.
  • Solutions: Filter, flocculation, flotation, biological treatment (optional, only in operation when needed), sludge management with screw press
  • Added value services: Project execution, commissioning and monitoring
  • Intelligent services: NSI Digital Platform for monitoring and control
