The Best in Design & Quality

At Pure Aquatics in Port Macquarie, we supply drum filters on the Mid North Coast, throughout Australia and worldwide. A drum filter is a type of mechanical filter used in aquaculture systems to remove solid waste particles and debris from the water. Trome drum micro screen filters are the industry standard for pre-filtration, solids and TSS removal in aquaculture applications. 

Together with our partners, Pure Aquatics offer accurate sizing of drum filters applied to specific applications and TSS levels whilst providing only the best in design and quality. Trome drum micro screen filters offer a range that suits the smaller end of the market, opening up drum filtration to the smaller operator, quarantine and purging systems and research systems. Trome builds HDPE drum filters that are completely saltwater compatible (also available with freshwater backwash pumps). Their ability to construct smaller drum filters opens the technology to the smaller application that would otherwise have to utilise filter matt or filter socks. 

TM1 – 5,000LPH – 7,500LPH with 60 micron screens, TM2 – 15,000LPH – 20,000LPH with 60 micron screens, TM3 – 30,000LPH – 40,000LPH with 60 micron screens, TM4 – 60,000LPH – 75,000LPH with 60 micron screens 

Drum filters have been used for many years in commercial fish farms where flow rates are multiple times higher. Most drum filters on the market are designed for these larger RASs. These drum filters are not suited for smaller systems as can be found in research environments, hatcheries etc. Trome aims at these smaller RAS and with the TM1—the advantages of a drum filter are now in reach of even the smallest RAS. The new design, based on five years of experience in the field, together with the well thought combination of materials (HDPE, stainless steel, POM) results in a high-quality, reliable and price-efficient drum filter that can be used in both freshwater and seawater environments. 

Thanks to our extensive experience in aquaculture and that of our distributors, Trome will gladly advise you to ensure your drum filter best suits your needs.

NP Innovation—Drum Micro Screen Filters

lthough NP Innovation is a new company, our history is extensive. In fact, the company founders developed much of the micro screen market. Together we can demonstrate unrivalled experience and track record. 

It all started in 1984 when CEO Nils-Åke Persson was a consultant engineer, designing solutions for fish farms. However, the available filtration technology wasn’t adequate, and Mr Persson had a vision for how he could improve it. To make this vision a reality, he founded Hydrotech and just a year later his first micro screen filter became an instant success in the fish farm industry. Five years later, he released the drum filter, which became equally successful. In 1995 the company released its next innovation, the game-changing disc-filter micro screen, mainly targeting the municipal water treatment market. 

Finally, after almost 20 years of successful innovation, Nils-Åke Persson sold his company to American group US Filter, in 2002. Two years later, he left the company and his position as CEO. 

In 2013, Nils-Åke Persson and his partners returned, founding NP Innovation and reclaiming their position in the field of micro screen filter development. NP Innovation’s wide range of drum micro screen filters and disc filters for larger applications allows Pure Aquatics to cover larger instalments. 

With models to suit TSS levels from <10mg/L to over 50mg/L and drum diameters from 500mm to 2000mm (and up to 10 screen sections), NP Innovation can specify a drum filter for your specific application. 

The benefits of Trome drum filters are their small footprint, ease of use, low maintenance, reliability and fully independent and automatic operation.
