Aquaculture keeps fish healthy with Lamor’s reverse osmosis systems

Lamor's Reverse Osmosis Systems help the aquaculture industry keep fish healthy.
  • The aquaculture industry needs an environmentally friendly solution to help keep fish healthy. We are applying our experience providing fresh water systems to the cruise industry to aquaculture.

 

Seafood is a key part of cuisines all over the world. On average, each of us eats about 20 kilos of fish every year, and about half of this comes from aquaculture. Many wild fisheries have been overexploited, but fish farms can provide a sustainable supply. A main threat to fish farming is parasitic infestation, particularly by sea lice.

A common method to treat sea lice is by using hydrogen peroxide, yet there are two potential problems that are becoming more apparent over time. One is environmental concerns. The second problem is a fear of sea lice building up a resistance to this chemical. As early as 2015 a study warned of salmon louse losing their sensitivity to hydrogen peroxide at a Norwegian fish farm.

 

Fresh water for healthy salmon

Salmon is one of the key species in aquaculture and accounts for about 70 per cent of the farmed fish market. Because of concerns about hydrogen peroxide many fish farmers are moving to more environmentally friendly solutions. One treatment is simple: fresh water. Salmon live in fresh water at different times of their natural lifecycle, but sea lice are only adapted to salt water. This means the salmon can handle a fresh water bath, but the parasites can’t.

Fish are exposed to fresh water in a live fish carrier so the lice lose their grip. The treated and healthy fish are then released back into their growing area. For fish farms at sea, this fresh water can be supplied by reverse osmosis (RO) systems.

Reverse osmosis purifies water by using a partially permeable membrane. Our RO systems are an excellent solution for desalination. RO uses relatively little energy to produce the fresh water compared to other desalination methods, such as multi-stage flash, multi-effect distillation and mechanical vapor compression.

Live fish carriers are now benefiting from the RO systems which were developed for the demanding needs of the cruise industry. Aquaculture needs fresh water just like the cruise sector, so they get to take advantage of years of research, development and improvements in RO and water treatment.

Protect your investment sustainably

Our systems are tailor-made to match the capacity and footprint you need. While many others in the industry only sell standard bulk systems, we can create the size to match your new or retrofitted vessel. 

The Lamor RO systems are manufactured to the high-quality standards we are used to in the global marine industry and provide the best energy efficiency on the market. They are highly automated and user friendly to provide worry-free and efficient operation. We can quickly serve our customers anywhere in the world through our fourteen global hubs.

Aquaculture water filtration is a way for the industry to protect their investment and do it in a responsible, efficient and sustainable manner.
