Construction & Industrial Stormwater: treatment requirements and optional routes. Branches do not represent a complete process or a requirement to dose products together. Process selection depends on water quality and project conditions.
Your process challenges
Chemistry matched to real operating conditions.
Start with the contaminant profile and project boundary, then compare a selective, testable treatment route.
Treatment approach
Construction & Industrial Stormwater: understand the treatment stages first.
Compare interception, settling and any conditional dosing / filtration according to runoff pollution zones and flow variability. Chemical treatment is not required for all stormwater.
Check together during selection
Screen materials or treatment routes by target species, background water quality and disposal conditions. Assess engineered treatment and natural-water applications separately.
Compare candidate products below by treatment objective. Evaluate different routes separately; the list does not imply simultaneous dosing.
Construction & Industrial Stormwater: match requirements to each treatment stage.
Compare treatment objectives, chemical functions and verification criteria stage by stage. Products in the table may be alternatives or serve different stages; they are not necessarily dosed together.
Define influent and objectives first
Share rainfall or incoming-water conditions, particles, pH, site contaminants and drainage targets. This helps organize suitable routes around the target contaminants and narrow the product and specification range.
Then confirm assessment limits
Screen materials or routes against target species, background water chemistry and disposal conditions. Assess engineered treatment separately from natural-water applications.
