Plant Description: The BCA Model ST-1100-3 Water Treatment Plant is designed to treat raw water for the removal of color, turbidity and other impurities and to provide a high-quality effluent for potable and domestic use. The plant combines the time proven principles of mixing, coagulation, flocculation, tube settler assisted clarification and high-rate filtration. The treatment process is a completely automatic, gravity flow operation. It consists of three process trains each rated to treat 367 gallons per minute and comprising the following components:

• Raw Water Flow Control.
• Chemical Coagulation and Rapid Mixing for:
  • Liquid Alum as Primary Coagulant
  • Soda Ash for pH Adjustment 
  • Polymer Coagulant Aid.
• Mechanical Flocculation (14 minutes Detention with Tapered Flocculation)
• Clarification Within a Tube Settler 31 Minutes Detention, 1.61GPM/Ft² Average Rise Rate at Maximum Flow.
• Filtration Through Dual Media Filter With Maximum Loading of 3.95 GPM/Ft² Post Treatment Soda Ash and Sodium Hypochlorite Injection
