Surface and Ground Water Treatment (Clarification System)


Surface and groundwater treatment refers to the processes and methods used to purify water sourced from rivers, lakes, reservoirs, and groundwater wells. These treatments remove impurities, contaminants, and undesirable substances from water so that the finished quality meets government and industry standards.

Water treatment typically involves several stages, including pre-treatment, coagulation, flocculation, sedimentation, filtration, disinfection, and pH adjustment. Pre-treatment may include screens or barriers to remove the large debris that can accompany raw water.

Coagulation and flocculation require chemical addition to cluster smaller organic particles into larger clumps, called “floc”. The result is sedimentation, a layer of organics that are easy to remove and facilitate filtration, which filters the remaining suspended particles.

Solutions like BW Water’s Hydro-PAQ™ facilitate the clarification process by hosting the coagulation, flocculation, and settling of solids in a single vessel.

Site-specific surface and groundwater treatment processes can vary based on the water source and desired water quality. The ultimate goal is to ensure that the final product meets the required drinking, irrigation, and/or industrial standards.
