Prior to design, HDS validated the biochemical oxygen demand (BOD) numbers at the site by effluent water testing which showed the campus facilities generated high strength wastewater due to the site’s residential dormitory and cafeteria daily functions. The effluent is averaging 800 to 1100. To treat this high strength wastewater the recommendations of the Kentucky Health Department were to utilise the following treatment tank designs. Two (2) 8,000 Gallon Concrete Pretreatment Tanks, Three (3) 2,700 Gallon Fiber glass Fuji Clean USA Aerobic Treatment Units (ATU) and, One (1) 9,720 Concrete Dosing Tank. In addition, the Kentucky Health Department also recommended the installation of 23,000 lineal feet of drip tubing with each drip emitter capable of an effluent application rate of 0.6 gallons per day, per square foot of soil.
Two 8,000 Gallon Concrete Pretreatment Tanks:
Aeration devices were installed inside to reduce the strength of wastewater to a BOD level of ±300 mg/L.
Three FujiClean USA CE30’s:
These tanks are designed without any mechanical moving parts inside for low maintenance requirements, high energy efficiency which lines up with the primary goals of Isaiah House Board of Directors. Each unit only draws 4.08 kWh/day of power which for Isaiah House is calculated a little over a dollar a day for all 3 units. (Each treating a hydraulic load of 2,700gallons per day).
One 9,720 ConcreteDosing Tank:
With alternating duplex dosing pumps to send to the Perc-Rite® Drip Dispersal system.
Twenty-three linear feet of American Manufacturing Drip Tubing:
The disposal of the treated and filtered wastewater effluent, utilizing subsurface drip irrigation (SDI) is a unique, but tried and true dispersal system for distributing effluent into the soil. The system incorporates disc filtration, time and level-controlled application, and an ultra-low rate of drip distribution. This equals4.4miles of tubing in the softball field.
