Oil Water Separators For Automotive Workshops

Streamlined oil separation from auto workshop wastewater

Key wastewater challenges for the auto workshop industry

  • The discharge of wastewater containing oil, grease, and other contaminants.
  • Oily wastewater running municipal sewer systems can lead to violations and fines.
  • Reliance on equipment that requires lubrication results in oily water discharge.
  • Treating oily wastewater can be expensive, especially for smaller auto workshops.
  • Operational efficiency for an auto workshop decreases without a separation system.
  • The release of harmful substances into local water bodies.

Industry overview - managing oil in auto workshops

An oil water separator is used in auto workshops to effectively separate and remove oil, grease, and other contaminants from the wastewater generated during various automotive maintenance and repair processes. This ensures compliance with environmental regulations and prevents the release of harmful substances into the environment.

Cleanawater's oil water separator serves as a vital solution for the auto workshop industry, effectively addressing the challenge of managing oily wastewater. With capacities ranging from 1,000L to 5,000L nominal flow rate per hour, our separators can be easily installed and maintained, helping all auto workshops meet and maintain water authority regulations.

Understanding the oil removal process

Step 1


The pre-treatment stage involves filling the oil water separator with the contaminated water from engine wash down and vehicle washing practices. 

Step 2

Primary separation

Large oil droplets and other solids rise to the surface to form a floating layer of sludge. This can be removed mechanically.

Step 3


The water moves into a coalescing chamber equipped with specialised media packs to separate oil.

Step 4

Secondary separation

The remaining free-floating oil and smaller suspended solids continue to rise to the surface.

Step 5


The clarified water, which has undergone multiple stages of separation, exits the oil water separator system through the outlet pipe.
