Design Specifications
The AguaClara Full Scale Plant removes large sediment and grit before introducing coagulant and chlorine through a chemical dosing process. After this, the water begins a flocculation and sedimentation process where the sediment and particulate matter is collected in a flock blanket and disposed of as waste. The residual water passes through angled plates and enters a six-layered Stacked Rapid Sand filter. The effluent water is collected in a distribution tank for use.
