Your challenges
Tackling complex water and wastewater challenges across various energy sectors, such as:
How does NSI handle your needs?
To which energy subindustries water treatment can be applied?
Based on your requirements and contract type (DBFMO), we select in-house technologies suited to your energy application, supported by decades of experience in water treatment and recovery. We support the following segments:
Biofuels
- Treat wastewater rich in organics and nutrients.
- Recover biogas for energy generation.
- Enable water reuse and nutrient recovery.
Hydrogen
- Treat process water for electrolysis and fuel cell production.
- Implement closed-loop systems for ultrapure water recovery.
- Manage waste brine and chemical contaminants.
Waste-to-Energy
- Leachate and condensate treatment.
- Odour control and air scrubber water management.
- Heat and nutrient recovery from digestate and wastewater.
Upstream (Oil & Gas)
- Produced water treatment and reuse.
- Desalination and advanced oil-water separation.
- Sludge dewatering and disposal.
Downstream (Refineries & Petrochemicals)
- Cooling tower blowdown reuse.
- Process water polishing and zero-liquid discharge (ZLD) solutions.
- Removal of hydrocarbons and heavy metals.
Our solutions
Based on your requirements and contract type (DBFMO), we select our inhouse technologies based on our extensive (waste)water knowledge of the food and beverage industry.
