WASTEWATER TREATMENT TRAINS MAKE FOR HAPPY CAMPERS FOR YEARS TO COME

Project: Camp Courageous in Monticello, Iowa, USAFactsCamp Courageous is a non-profit organization that provides year-round recreational and respite care for people with special needs.

In 1974, when Camp Courageous first opened its doors to campers, it had five buildings on 40 acres of land and served 211 people. The camp now has 25 buildings on 300 acres of land and hosts more than 9,000 campers each year.

The camp’s original wastewater treatment system could not cope with the site’s growing needs. Rather than scale back operations – and turn people away – Camp Courageous looked for a long-term solution to effectively treat its wastewater.

ChallengesThe project presented several challenges, including:

Flow and wastewater strength fluctuations Seasonal flow fluctuations were expected between peak use during the summer and low-use periods. There would also be fluctuations during the winter, when more people visit the camp on weekends and holidays than on weekdays.

Flow fluctuations were expected to impact wastewater strength. For example:• Peak use = Frequent toilet flushing with high NH4 • Food preparation = High BOD5 and FOG

Surface discharge into a sensitive area Treated wastewater would be discharged into the adjacent Maquoketa River in Pictured Rocks County Park.

SolutionShive-Hattery, the engineering firm in charge of the project, needed an economical system with the flexibility to handle flow and strength fluctuations and the proven performance to meet Iowa’s wastewater treatment standards.

Premier Tech Aqua’s technologies checked all the right boxes. Shive-Hattery designed two independent treatment trains – each using the EcoprocessTM MBBR (Moving Bed Biofilm Reactor), Ecoflo® Coco Filter, and a disinfection unit – to ensure effective wastewater treatment tailored to Camp Courageous’ needs.

ResultsThe Camp Courageous treatment trains were installed in September and November 2017 respectively. Both trains have performed well in the field, as demonstrated by the results in the following table:

“Premier Tech Aqua was a pleasure to work with... from design through installation, and, most importantly, support after completion. The results speak for themselves.”

Combining high performance with a compact and robust design, the EcoprocessTM MBBR is the clear-cut treatment solution for projects with fluctuations in daily flow and wastewater strength. This modular system is designed to reduce high loads of BOD5 and NH4 and is ideal for:

• Truck stops, hotels, and campgrounds• Convenience stores with food preparation• Fast food chains• Breweries and wineries • Projects where space is limited

1. Primary treatment tank 6,000 US gal.• Captures suspended solids• Screens trash and reprocesses biological sludge

2. Equalization tank 2,000 US gal.• Provides metered dose to secondary treatment tank• Controls aerator operating time (when there is no water

at the tributary, the blowers stop)

3. EcoprocessTM MBBR 4,500 US gal.• Fixed-film media keeps biomass inside the tank• Aeration moves media and self cleans bacterial support

(increasing surface area and improving performance)

4. Clarification tank 4,500 US gal.• Separates solids from liquids in the sludge and scum resulting

from the treatment process

5. Ecoflo® Coco Filter 15,000 US gal./d• Requires no energy for treatment• Organic filtering media is renewable and recyclable

6. DiUV Self-Cleaning 15,000 US gal./d• Ensures constant and controlled flow• Optimizes exposure of pathogens to UV rays
