Complete set of oily wastewater equipment

Oily wastewater mainly comes from industrial sectors such as petroleum, petrochemicals, steel, coking, gas generation stations, and mechanical processing. Oil pollutants in wastewater have a relative density of less than 1, except for heavy tar which has a relative density of 1.1 or higher.

Oil containing wastewater - Explanation
Oil substances usually exist in three states in wastewater.
(1) Floating oil with droplet size greater than 100 μ m, easy to separate from wastewater. The dispersed particles of oil in wastewater are relatively large, with a particle size greater than 100 microns, making them easy to separate from the wastewater. In petroleum wastewater, this oil accounts for 60-80% of the total oil content in the water.
(2) Dispersed oil. The particle size of oil droplets ranges from 10 to 100 μ m and is suspended in water.
(3) Emulsified oil, with droplet size less than 10 μ m, has a very small dispersed particle size in wastewater and is in an emulsified state, making it difficult to separate from the wastewater.
(4) Dissolved oil, the state in which oil dissolves in water.
