Fluorine-containing
Wastewater Treatment Facilities
Fluorine-containing wastewater is generated from glass substrate etching, equipment producing non-chromium wastewater and so forth from various types of production facilities, and wastewater treatment must lower fluorine content to 8 mg or less.
NCE has continued its research of fluorine treatment for many years, successfully developing facilities capable of meeting wastewater emission regulation standards. In addition to calcium treatment agents, we propose two-stage flocculation-sedimentation treatment, adding of phosphoric acid, chelate resin adsorption following flocculation and sedimentation, and other treatment methods depending on the properties of the water.
Components of Fluorine-containing Wastewater Treatment Facilities
The following equipment is used to treat fluorine-containing wastewater.
Flocculation-Sedimentation Equipment
This equipment removes heavy metals, suspended solids (SS), colloidal substances and other substances found in inorganic wastewater.
Hazardous substances in the water can be quickly separated and precipitated out.
Rapid Filtration Towers
Our rapid filtration equipment provides filtration of supernatant water in the sedimentation tank and removal of solid matter, suspended particles, etc. in such water. The upper filter media can efficiently remove everything from large particles to small suspended solids (SS).
Activated Carbon Adsorption Towers
Even after flocculation-sedimentation, filtering and other such treatments, subtle odors and small amounts of organic compounds will remain. Our activated carbon adsorption towers can clean your water even further.
Fully Automated Compression Filter Presses
Our fully automated compact filter press equipment boasts 0.7 MPa of compressive strength, making it possible to produce low-water-content filter cakes from high-viscosity slurry.
