Case Study: Fluoride Removal Wastewater Treatment Project for an Automobile Manufacturing Plant
August 6, 2026
Project Background
With increasingly stringent industrial wastewater discharge standards, the control over characteristic pollutant fluoride has been elevated to quasi-Class III requirements under the Environmental Quality Standards for Surface Water (F⁻ ≤ 1.0 mg/L).Fluoride-containing wastewater generated from painting, phosphating, and surface treatment processes in the automobile manufacturing industry has become a key target for environmental management.
Project Overview
At a large-scale automobile manufacturer, the fluoride concentration in the effluent from the existing wastewater treatment system remained stable at approximately 15 ppm exceeding the latest local discharge limit of ≤1 ppm.Consequently, the enterprise initiated a dedicated upgrade and retrofit project, requiring the design of a high-efficiency fluoride removal system with a treatment capacity of 20 m³/h to ensure long-term compliance with discharge standards.
