Car Wash Water Treatment
Water treatment for car washes: a water softener additive against hard-water spotting, and HydroFloc to clear wash-bay wastewater for reuse or discharge.
Hard water in, dirty water out
Water quality decides both the finish and the running cost of a car wash. Hard water leaves mineral spots and reduces how well shampoo foams; wastewater full of suspended dirt cannot be reused or discharged as it is.
- Water softener additive — conditions hard water so shampoos work better and cars dry with fewer spots.
- HydroFloc — added to a settling tank, it makes dirt and suspended particles clump and settle, so clear water can be drawn off the top. Typical dose 50–100 ml per 100 L of wastewater.
Fewer spots, less water
Softer water reduces the chemistry needed per car and the spotting customers complain about. A settling tank treated with HydroFloc makes water recycling practical for rinse stages. Where spots do appear, a water spot remover takes them off, and a drying agent helps water sheet off the car.
Why do cars get water spots after washing?
Minerals in hard water stay behind when droplets evaporate. Softening the water, using a drying agent and drying promptly all reduce it.
