Check together during selection
Differentiate programs by oil phase, salinity, temperature and downstream use. Evaluate demulsification, separation, scale control and microbiological control separately.
Compare candidate products below by treatment objective. Evaluate different routes separately; the list does not imply simultaneous dosing.
Oily Industrial Wastewater & DAF Support: 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 oil phase, source of emulsification, pH, current products and flotation or settling equipment. This helps distinguish oil, particle, scaling and microbial-control tasks and narrow the product and specification range.
Then confirm assessment limits
