Coating Process Wastewater Treatment Facilities
Pretreated wastewater from coating processes can be broadly classified as water containing zinc phosphate, iron phosphate or fluoride. Furthermore, wash water used after electrodeposition which contains high BOD and COD levels must undergo nitrogen and biological treatment.
NCE’s coating process wastewater treatment starts with the selection of an inorganic flocculant appropriate to the wastewater being treated, and we then provide equipment for flocculation and sedimentation, biological treatment, rapid filtration, activated carbon adsorption, and finally reduction of BOD and COD to below regulation values.
Components of Coating Process Wastewater Treatment Facilities
The following equipment is used to treat wastewater from coating processes.
This equipment is used in inorganic wastewater treatment.
Heavy metals, suspended solids (SS), colloidal substances and other substances contained in the wastewater are neutralized and then quickly separated and precipitated out.
Pressure Flotation Equipment
This pressure flotation equipment is used to separate floc, oils, suspended solids (SS) and other organic compounds.
Micro-bubbles are brought into contact with substances, separating them via flotation to the top in a short period of time.
Biological Treatment Equipment
Biological treatment is the most common method of treating of organic wastewater.
NCE recommends an aerobic wastewater treatment approach. We offer treatment methods tailored to the contents of the wastewater to be treated.
Nitrogenous Wastewater Treatment Equipment
Nitrogenous and phosphorus substances in industrial wastewater must be removed thoroughly for the protection of natural environment.
NCE can provide nitrogen removal technologies through this equipment, based on the knowledge that NCE has acquired from the experience of wastewater treatment for long time.
Rapid Filtration Towers
This equipment provides supernatant filtration and removal of solid matter, suspended particles and so forth via rapid filtration.
The upper filter media can efficiently remove everything from large particles to small suspended solids (SS).
Activated Carbon Adsorption Towers
Even after passing wastewater through flocculation and sedimentation treatment and filtering it, trace colors, odors and quantities of organic compounds will remain.
Activated carbon adsorption towers can be used for secondary treatment. BOD and COD reduction are also possible.
Fully Automated Compact Filter Presses
This fully automated compact filter press equipment removes water from sludge.
It is designed to handle difficult-to-filter slurry, and the resulting filter cake can be reliable removed using a removal device.
