Protect fish health and operational performance

Why water quality matters

Water quality is critical in modern aquaculture. Poor water conditions increase the risk of disease outbreaks, reduce fish welfare, and can impact both operational efficiency and profitability.

Our treatment systems are developed to:

  • Reduce biological contamination
  • Improve fish welfare during transport and handling
  • Support compliance with industry regulations
  • Minimise environmental impact
  • Secure stable water quality throughout operations

Advanced process-water treatment technology

Norwegian Greentech systems combine mechanical filtration and UV disinfection to ensure effective treatment of process water in demanding aquaculture environments.

Mechanical filtration

Removes particles and organic material from the water before UV treatment, improving system efficiency and overall water quality.

UV disinfection

High-performance UV technology neutralises bacteria, viruses, and harmful microorganisms without the use of chemicals.

Compact system design

Designed for easy integration on board live fish carriers and land-based aquaculture facilities with minimal footprint requirements.

Approved technology

Systems are developed according to industry standards and approved by relevant authorities.

Discover how UV technology lowers biological risk in land-based aquaculture

In land-based aquaculture, precise water quality control is essential for fish health and stable operations.

By continuously adjusting UV dosing to water flow and water quality, Norwegian Greentech ensures optimal UV intensity at all times. This reduces biological risk, improves operational reliability, and minimises energy consumption.

1. Fish health and growth

Disease Prevention

Clean water reduces the presence of pathogens, parasites, and harmful bacteria, which can cause diseases and infections in salmon.

It helps in maintaining a healthy immune system in fish, making them more resilient to diseases.

Optimal Growth Conditions

Freshwater with the right balance of nutrients and minerals supports the healthy growth of salmon.

Proper water quality ensures that the fish can efficiently utilise their feed, leading to better growth rates and feed conversion ratios.

2. Environmental and operational efficiency

Waste Management

Clean water helps in the effective breakdown and removal of waste products, such as ammonia and nitrites, which can be harmful to the environment.

It prevents the accumulation of organic matter that can degrade water quality and be toxic to the environment.

Oxygen Levels

Adequate dissolved oxygen levels are essential for the breathing and overall well-being of salmon.

Clean water ensures that oxygen levels remain stable, preventing stress and promoting healthy metabolic functions.

3. Sustainability and productivity

Sustainable Practices

Maintaining and generating clean water is part of sustainable aquaculture practices, reducing the environmental impact of fish farming.

It helps in conserving water resources by minimising the need for frequent water exchanges.

High Quality Produce

Clean water contributes to the production of high-quality salmon, which is crucial for market acceptance and consumer health.

It ensures that the fish are free from contaminants and pollutants, making them safe for consumption.

By ensuring clean and fresh water, salmon farmers can promote the health and growth of their fish, improve operational efficiency, and contribute to sustainable and productive aquaculture practices.
