Ultrasonic liquid inactivation equipment can kill all kinds of marine organisms well

Product Description

As the main means of transportation at sea, ships have played a huge role in international trade. However, if the microorganisms in the ballast water of ships are discharged locally without treatment, it will pollute the local ecological environment, seriously destroy biodiversity and even endanger human health. Over the past few decades, countries have studied and innovated methods for treating ballast water, but none of these methods can meet the five standards proposed by IMO: safety, practicality, economicality, effectiveness and environmental tolerance. Ultrasonic cavitation effect can kill all kinds of marine organisms well, thereby protecting the safety and lifespan of marine facilities.

Ultrasonic liquid inactivation equipment

As the main means of transportation at sea, ships have played a huge role in international trade. However, if the microorganisms in the ballast water of ships are discharged locally without treatment, it will pollute the local ecological environment, seriously destroy biodiversity and even endanger human health. Over the past few decades, countries have studied and innovated methods for treating ballast water, but none of these methods can meet the five standards proposed by IMO: safety, practicality, economicality, effectiveness and environmental tolerance. Ultrasonic cavitation effect can kill all kinds of marine organisms well, thereby protecting the safety and lifespan of marine facilities.

Classification of Marine organisms:

Marine fouling organisms can be classified into the following three categories.
--Soft growths such as spongy tissues.
--Bacteria and unicellular organic matter, such as various bacteria and algae.
--Hard marine animals, such as barnacles and bivalve mollusks.

The main types that pose significant harm are hard fouling organisms.
--It will damage the surface of metal structures, leading to localized corrosion.
--Larger fouling organisms can block drainage and water supply pipes, heat exchangers, and other equipment, severely impacting the safety and lifespan of marine facilities.

Governance of the current situation

Given the severe hazards caused by marine fouling organisms, various methods can be employed for prevention and elimination of fouling organisms, primarily categorized into physical and chemical methods. Traditional physical and mechanical removal methods have drawbacks such as high labor intensity and low work efficiency, and may even cause mechanical damage to marine facilities; in terms of chemical anti-fouling, existing coatings have issues such as high production costs, limited effective duration, and environmental pollution risks.

Ultrasonic ballast water treatment

Ultrasonic ballast water treatment equipment primarily utilizes the 'cavitation effect' of ultrasonic waves. When ultrasonic waves of a certain frequency and intensity are applied to a liquid, numerous tiny bubbles are generated. These tiny bubbles undergo a series of physical and chemical changes during their formation, oscillation, growth, contraction, and collapse.

Bubbles in liquids generate over hundreds of atmospheres of pressure and temperatures exceeding thousands of degrees Celsius at the moment of rupture. This can rapidly peel off biofouling organisms and shatter their epidermal cells, thus achieving anti-fouling purposes. Ultrasonic cavitation technology has its advantages: it not only features simple device design and convenient operation but also does not produce secondary pollution. Most importantly, the synergistic effect of ultrasonic waves and hydraulic cavitation is quite effective, with low energy consumption.

Ultrasonic anti-sea life technology has been put into practical application and achieved good results. This technology boasts advantages such as simplicity, cost-effectiveness, efficiency, and environmental friendliness. It can not only remove sea life attachments on the inner walls of seawater pipelines and filter screens but also kill juvenile sea life.
