Due to the rapid growth of this automotive parts manufacturer, water demand within the plant had outgrown its water production capabilities.
After reviewing treatment options, Tonka Water’s proposed filter layout was chosen. The raw water entering the plant had high concentrations of iron, manganese, and moderate hardness that needed to be reduced prior to plant distribution. Water usage is around the clock to keep this plant on line, with peak demand of approximately 500 gpm.
The water treatment facility consists of chemical oxidation of iron and manganese, one OptaCell Plus™ pressure filter, a booster pump station, a hydropneumatic storage tank, followed by RidION™cation ion exchange vessels for softening prior to plant distribution.
The OptaCell Plus™ pressure filters are designed with multiple cell compartments above AND below the underdrain within for a total of six individual filter cells. Five cells are currently utilized with one additional cell available for future plant expansion. This unique filter design allows for an individual cell to be backwashed or taken completely off line while the others remain online.
Each filter cell supplied includes the Simul-Wash™ backwash process. This is a key process design that is saving MACI money every time they backwash. As the demand for water increases, the hydropneumatic tank discharges water through the softeners and out into the plant. The RidION™ ion exchange softeners reduce the water hardness prior to plant distribution.
The raw water analysis summarized below reflects moderate to high concentrations of iron manganese and hardness existing in the water. The treatment process has been highly efficient in delivering high quality water as indicated below.
|Iron (Fe)||1.5 – 2.3 mg/L||Not Detected|
|Manganese (Mn)||0.07 mg/L||0.02 mg/L|
|Hardness (CaCO3)||< 300 mg/L||< 90 mg/L|
