Horizontal filters keep water crystal clear for 1000 visitors per day

Having opened four Splash Kingdom water parks in Texas, the park owners knew what to expect when designing their fifth Splash Kingdom in the state: a 1000-person pool party each day. Opening in 2015 in the city of Nacogdoches, the park’s management also had a fair idea of what the hot summer of 2016 would bring. Estimates forecast visitor numbers at 60,000 for the season.

The park’s engineers provided very clear specifications for the park’s filtration system to ensure they maintained a safe, healthy and fun environment for visitors. Not only did the filters need to be able to deal with typical pool water pollutants such as human body oils, dust and food particles, they also needed to be resilient enough to cope with 5000 gallons (18,927 L) of water per minute.

Besides a strict budget, the complex project was constrained by a specific time frame — everything needed to be ready in time for the scheduled opening date. Any delay in installing the filtration system would have a knock-on effect on other trades, preventing the park from opening and costing the owners.

The only outdoor water park to be built in the US in 2015, Splash Kingdom has four pools: Lazy River, Catch Pool, Kids’ Area and Activity Pool. Seven horizontal commercial Micron filters from Waterco were specified for the park: the M5000, M4875, M48106 and HRV 36.

Waterco has introduced a hydraulically balanced lateral configuration for its entire range of commercial horizontal fibreglass filters. A conventional lateral system results in uneven fluidisation of the filter media bed. The beginning of the lateral system experiences a strong flow of water, which gradually decreases along the length of the lateral piping. Backwash flow also decreases towards the end of each lateral, resulting in non-uniform lifting of the filter media bed.

This lateral configuration provides a more natural flow of water through the filter, ensuring optimum water filtration and balanced fluidisation of the filter bed during backwashing. Its individual laterals are shortened while maintaining filter media bed coverage to reduce the friction head loss of each lateral and further improve the filter’s hydraulic efficiency. This reduces backwash run times, saves valuable water and produces a flatter, more uniform filter media bed after backwashing.

The filters’ compact, horizontal design also allows installation with the minimum amount of space wasted. The filters are available with a 500 mm (M) filter media bed and a 1200 mm (MD) filter media bed.

The technology proved the right solution for Splash Kingdom.

Construction of the park commenced on 20 December 2014 and the Waterco filters were installed the week of 14 July 2015. The park opened for business just 16 short days later.

According to General Manager Jared Troutman, the company chose Waterco because it had the right products to meet the needs of the entire park’s water filtration requirements, and they were in stock and ready to ship immediately.

Ultimately, the water filter installation project was completed on time and on budget. “Everything happened on time and Waterco fully delivered on what it promised,” said Troutman.

“The sizing met our filtration needs and they matched the specified requirements of the aquatic consultant. Waterco has been a good partner and addressed all operational concerns.

“The water clarity is perfect. It was also the most budget-conscious solution. A big plus here!”
