GroPro Slow Media Filter
Benefits of Bio-filters
“Rockwool (Grodan type) has performed better in nurseries than sand, because it becomes clogged less easily than sand filters”, and additionally, “Several plant pathologists from Europe and Australia have verified the effectiveness and the practical value of this filtration procedure for nursery irrigation systems”.

How the GroPro Slow Media Filter Works
GroPro filtration works by allowing water to pass through a media at a slow rate, which allows beneficial organisms to feed on and eliminate harmful organisms – such as pithium, phytophthora, rhizoctonia, nematodes and viruses. The water passes through the GroPro Slow Media filter and is stored to be reused in the nursery with complete confidence. AIS Greenworks has supplied and/or installed a number of successful GroPro filters in nurseries, from small-scale to large-scale projects, along the east coast of Australia, and we work throughout Australia. It is important to note we have studied the clinical results of these filters and they are all performing to an exemplary standard. AIS Greenworks has done the research and development on slow media filtration for you. There are several considerations when designing such systems, from water application and drainage method in the filter, through to the unit operating 24 hrs per day, 365 days per year to ensure the effectiveness of the system continues at optimal levels.
