Self-cleaning filter enables campground to eliminate chlorination in drinking water
Stanley Park Campground is a popular Manitoulin Island, Ontario, Canada, summer getaway and retreat. The park has 230 fully serviced sites, as well as three community bathroom and shower areas. The park can host upwards of 1,000 people per day in the hot summer months, from daily campers to long-term retiree summer residents.
In January 2008, park management started to investigate different alternatives to supply water to the entire park. In the past, the water was pumped directly from Lake Mindemoya, chlorinated and put out for consumption. The park has very stringent testing practices, and the water that was available for consumption was tested monthly.
At certain times of the year, the particle count of debris would rise. This led management to search for a solution to reduce the particle count and, thus, a way of filtering the water to make it cleaner. The park typically runs approximately 65 gpm into two pressure vessels so that a pressurized source of water is available for consumption. The challenge was to find a filter that would be fully automatic and provide drinking water quality down to 5 micron while also protecting the UV system.
The park originally installed two Orival ORG-015-LE filters as a pilot. The 1.5-in. units had a screen area of 128 sq in.; after the pilot, it was determined that more screen area was necessary to achieve the overall goal of eliminating the chlorine with ultraviolet (UV) disinfection.
The park chose to install a 4-in. ORG-040-LE filter with a screen area that was more than five times greater and capable of handling the flow at a filtration level of 5 micron or .0002 in., which is 75% cleaner then drinking water in most municipalities.
The small footprint allowed the park to install the Orival filter in a tight area.
In early 2009, a UV disinfection system was installed, and the water is now a better quality than with the chlorine disinfection that was being used.
“We have some of the cleanest water available and have got rid of the expense and handling of large amounts of chlorine,” said Carl Tolsma, owner of Stanley Park. “Our filter has run great with very little maintenance and expense.”
