Solution

Trickling filter is an ideal way for purifying oil refinery wastes.

Explanation:

Oil refinery wastes contain dissolved organic pollutants such as hydrocarbons and phenols. A trickling filter is a biological treatment method in which wastewater is passed over a bed of rocks or plastic covered with microorganisms. These microorganisms break down the organic pollutants in the presence of oxygen and help purify the wastewater.
