Low vacuum plasma processes


When an article possesses an intricate shape, traditional methods of surface engineering (for example immersion in a chemical bath or spraying) may be either too expensive or impractical. That was the challenge InNano faced when trying to solve corrosion and fouling/clogging problems in screen filters. Screen filters are the active component in automatic backwash filters which are now the standard in ballast water treatment systems and which are also becoming increasingly adopted by other multi-billion dollar industries where liquid filtration is a must. Examples are produce water treatment (oil & gas), irrigation, cooling tower, aquaculture, desalination, municipal waste water treatment, etc.


InNano designed a now patent-pending process for applying Nanocoating to screen filters in an efficient way, such that screen filters made of 316 l stainless steel or even lower grade ones can have a corrosion performance equaling or exceeding that of expensive and exotic stainless steel, e.g 254 SMO. This is in addition to the coating providing an added advantage of difficult-to-foul and easy-to-clean surfaces, unlike the exotic steel grades. When nanocoated, screen filters made of 300 series stainless steel therefore promise several million dollar savings even for a small scale manufacturer, in addition to vastly enhanced operational efficiency.


Our nanocoating is a single solution to the challenges of corrosion, fouling/clogging, friction (e.g hydrodynamic drag) and abrasive wear. InNano is working towards establishing a production plant for coating screen filters by last quarter of 2019 in order to take advantage of an expected boom in ballast water treatment system installations. We are also looking for partners to demonstrate the effectiveness of nanocoated screen filters in a variety of fluid filtration areas.
