Carwash Recycle System

Vehicle waste water treatment uses a multi-step process to remove contaminants like oil, dirt, and chemicals, making the water safe for reuse or discharge. Key methods include oil-water separators, sand and membrane filtration, and often biological treatment to break down organic matter, with the treated water typically used for pre-washing.

Common treatment steps

Mechanical pre-treatment:

Oil and grease traps: Use gravity to separate lighter petroleum products from the water.

Sand filters: Capture larger solid particles and suspended solids.
Dissolved air flotation (DAF): Injects air bubbles to lift suspended contaminants to the surface for removal.

Biological treatment: Uses microorganisms to break down organic waste, reducing chemical oxygen demand (COD).

Filtration and separation:

Centrifugal separation: Uses force to separate heavier particles from the water.

Microfiltration and ultrafiltration: Use advanced membranes to remove finer contaminants, producing high-quality water.

Advanced treatment:

Activated carbon filtration (ACF): Further polishes the water by removing residual chemicals and odors.

Advanced Oxidation Processes (AOP): Used to break down stubborn pollutants.

Benefits of treatment

Environmental protection: Prevents water pollution in waterways and groundwater.

Water conservation: Recycles water for use in pre-washing and other non-potable applications.

Cost savings: Reduces water bills and sewage disposal costs.
