سیستم های تهویه هوای فضاهای سرپوشیده باید بطور مرتب و منظم گندزدایی شوند. باکتری لژیونلا در سیستم های تهویه هوا غیر بهداشتی زندگی و تکثیر می کند؛ یک سیستم تهویه هوای غیر بهداشتی را عامل اصلی شیوع و گسترش این باکتری می دانند. برای برطرف کردن این مشکل؛ لازم است بیو فیلم های داخل این سیستم های تهویه هوا را برداشته و آنها را بطور مرتب تمیز کرد.
این دستگاه برای تولید سدیم هیپوکلرایت (NaOCl 10,000 ppm) طراحی شده است که یک ماده گندزدا برای گندزدایی آب داخل لوله های سیستم تهویه هوا می باشد.

Since the introduction of steel-hulled vessels around 120 years ago, water has been used as ballast to stabilize vessels at sea. Ballast water is pumped in to maintain safe operating conditions throughout a voyage. This practice reduces stress on the hull, provides transverse stability, improves propulsion and maneuverability, and compensates for weight changes in various cargo load levels and due to fuel and water consumption. While ballast water is essential for safe and efficient modern shipping operations, it may pose serious ecological, economic and health problems due to the multitude of marine species carried in ships’ ballast water. These include bacteria, microbes, small invertebrates, eggs, cysts and larvae of various species. The transferred species may survive to establish a reproductive population in the host environment, becoming invasive, out-competing native species and multiplying into pest proportions. The problem of invasive species in ships’ ballast water is largely due to the expanded trade and traffic volume over the last few decades and, since the volumes of seaborne trade continue to increase, the problem may not yet have reached its peak yet. The effects in many areas of the world have been devastating. Quantitative data show that the rate of bio-invasions is continuing to increase at an alarming rate and new areas are being invaded all the time.
