Aquaculture

Ozone is a sustainable and environmentally safe treatment for water that is chemical-free, energy-efficient and cost-effective.

For the aquaculture industry, Aclarus Ozone provides water treatment solutions for the following operational challenges:

Source water purity
Water conservation, re-use and wastewater

Ozone Advantages for the Aquaculture Industry

Ozone is increasingly used in aquaculture due to its numerous advantages over traditional water treatment methods. Supplementing or replacing an existing system with an ozone system has the potential to boost a company’s advantage over its competitors.

Ozone has the following advantages:

✓ Provides superior, natural disinfection that promotes healthier fish, faster rate of growth, more abundant hatching and lower death rates;

✓ Chemical-free, it breaks down to oxygen after treatment;

✓ Removes bacteria, viruses, cysts, organic and inorganic contaminants; reduces waterborne diseases;

✓ Prevents iron-reducing bacteria (IRB) from affecting fish health in the hatchery;

✓ Neutralizes unhealthy minerals, like iron, sulphur and manganese;

✓ Removes contaminants of emerging concern (CEC’s), such as pesticides, organic matter, various microbes, pharmaceuticals and micro-plastics;

✓ Removes any colour, taste or odour;

✓ Returns source water to local watersheds as clean effluent;

✓ Conserves water by reducing the amount of water used;

✓ Produced onsite, removing the need to purchase, store and physically handle chemicals;

✓ Lowers operating costs because there is no need for expensive chemicals or UV bulbs;

✓ Can be used to supplement other treatment processes.

Source Water Purity

The purity of the source water in the hatcher has a direct impact on the health and quality of the fish being cultivated. Ozone promotes a faster rate of growth and healthier fish, lowering the rates of death. It also promotes more abundant hatching.

Ozone offers the fastest disinfection – even at low doses (e.g. <2ppm) – for bacteria, viruses and cysts, as it ruptures cells upon contact. Unlike chemical treatments, fish cannot be “overdosed” by ozone treatment. Moreover, ozone does not allow bacteria or viruses to develop resistance or immunity to water treatment.

Ozone can be used “on demand” to solve multiple water treatment issues safely and efficiently. Regardless of the source of the water, ozone and post-filtration will quickly remove:

Pathogens:

Bacteria (E. coli, Streptococcus, Cholera, Pseudomonas, Mycobacterium)
Virus (Adenovirus, Legionella, Rotavirus, Salmonella, influenza, hepatitis, polio)
Cysts; (Giardia, Crypto, Cyclospora, E. Dispar)

Contaminants:

Metals - (Iron, Manganese, Sulphur, Lead, Arsenic)
Organics - (Biofilm, Algae, Tannin, Colour, NOM)
Inorganics - (Cyanides, COD)
Chemicals – (Chlorine, sulphur dioxide, and chlorine-containing organic by-products (e.g. trihalomethanes)

Contaminants of Emerging Concern (CECs):

Pharmaceuticals and Personal Care Products
Hormones, Antibiotics, Medications
Estrogen, Sulfamet, Oxycodone, Ibuprofen, Triclosan
Amphetamines, Cocaine, Opioids
PFAS (Perfluoroalkyl and Polyfluoroalkyl Substances - Teflon)
Micropollutants & Microplastics

Ozone has no impact on pH levels in the water and leaves no residual, as it breaks down to oxygen before use.

Water Conservation, Re-Use and Wastewater

Ozone helps conserve water because aquaculture operators can re-use treated ozone water in their operations without any harmful impacts. Water treated with ozone promotes healthier fish, faster growth rates and more abundant hatchings because of its higher oxygen content. It has a far lower risk of accidental pollution in comparison to other water treatment methods, and it actually improves the effectiveness of biological and particulate filtration.

Ozone also safely treats wastewater. It produces oxygenated water – with no harmful by-products – that is safe to discharge into watersheds without environmental concerns. It is a cost-effective treatment that enables aquaculture operators to achieve regulatory compliance and reduce fees and fines.

Ozone Aclarus engineers assess the wastewater needs for each manufacturer and design a solution to fit the need through testing and/or pilot demonstrations. This is done to determine the level of treatment and ozone required (e.g. disinfection, biochemical oxygen demand (BOD), chemical oxygen demand (COD), total suspended solids (TSS), etc.).

While effective on its own, ozone can be combined with other oxidation treatments to form Advanced Oxidation Processes (AOP). AOP can offer even more enhanced treatment by forming hydroxyl radicals, amplifying the treatment effect. The most typical form of AOP is achieved with a combination of ozone and UV or ozone and peroxide.

Aclarus Ozone Systems Overview

Aclarus Ozone systems generate ozone on-site, with an ozone level calibrated for each application and flow rate. The systems are scalable to accommodate microbreweries to large-scale operations and they offer advanced ozone generation, mixing and control systems for reliable and accurate treatment.

Aclarus systems are easily retrofitted into existing facilities and are modular, to allow expansion when required. They can range from simple on/off systems to fully programmable control systems with remote monitoring, alarm integration, ozone dose control and more.

Aclarus’ advanced saturation systems maximize ozone transfer into water at an average of over 90% compared with traditional transfer rates of approximately 10%. Using inline monitors, the water is measured for automated control to either increase or decrease the ozone level to remain at a setpoint for optimal function.

Following ozonation, the water is filtered and then ozone is either removed for incoming use or remains in the water for use in sanitation. In many cases ozone can work in a closed loop CIP to greatly lessen water use and waste.

Aclarus Ozone systems also remove excess ozone from the water and destroy it, limiting potential off-gassing by using integrated air monitors for safe workspaces.

Cost Comparison

There is a common perception that ozone is an unaffordable approach to water treatment. In fact, the average operational cost of the Aclarus Ozone System is approximately 5-10 cents per 1,000 litres of treated water, offering the lowest Lifetime Operating Cost (LOC) compared to other technology and a quick Return on Investment.

Aclarus Ozone systems are found in a wide range of applications, including industrial and municipal operations, precisely because they are a cost-effective and reliable treatment. Aclarus advanced and affordable designs have brought ozone to multiple markets that have not previously used ozone.
