Myth: “If oil isn’t visibly floating on top, then there's no oil in the water.”
Fact: Not all oil separates into a visible layer. Industrial processes, detergents, agitation, and heat can create emulsified oil (tiny droplets suspended throughout the water) that may not be visible to the naked eye. Even when wastewater appears clean, residual oil can interfere with treatment systems, impact discharge quality, and create compliance challenges. Understanding the difference between free oil and emulsified oil is often a critical first step in selecting the right treatment approach.
Valicor works with facilities and manufacturers to evaluate oily wastewater streams and identify treatment strategies that address both visible and hidden contaminants.
