A system for continuously treating water with residual oil and/or solids includes a treatment system with inline mixers. A pH adjustment fluid may be added to the water in a first inline mixer. A micro-encapsulating flocculating dispersion flocculant may be added in a second inline mixer. The addition of the micro-encapsulating flocculating dispersion flocculant may cause flocculation of residual oil and/or solids in the water to form a pin flocculant. An activator may be added in a third inline mixer and a conditioner may be added in a fourth inline mixer. Bulk flocculant may be formed from the pin flocculant after the addition of the conditioner. The resultant mixture may flow to a settling tank where the flocculants may settle to produce treated water. After settling, the treated water may flow through a mechanical filter and/or a sorption filter to produce water suitable for desalination and/or other downstream processes.
