Industrial Wastewater Treatment
It helps in chemical treatment after removing large and small particles through physical treatment. The chemical treatment can remove heavy metals and non-degradable organic materials, and can save on cost on the required site. It is applied to sewage and wastewater that cannot be treated through the biological treatment method, and helps the biological treatment process to proceed smoothly.
As the first step in wastewater treatment, it protects the pump and removes large floating particles to increase the efficiency of the next step.
Physical & chemical precipitation
It is a method of aggregating and precipitating floating contaminants by dropping the coagulant to clear the supernatant.
It is a method of removing contaminants attached to air particles by dissolving air in the wastewater.
It is divided into aerobic decomposition and anaerobic decomposition, and it can remove organic matters in wastewater. Required drug costs are reduced. The combination of aerobic and anaerobic decomposition processes can remove nitrogen and phosphorus.
Activated sludge process
As a type of aerobic treatment, it is usually applied in the secondary treatment. It is considered economical and highly efficient in wastewater treatment.
As a process that uses a contact medium, its principle lies in the microorganism attached to the medium, decomposing and removing organic matter in wastewater.
It is suitable for the unbalanced wastewater BOD/COD ratio of 1 or less, and it can actively deal with bulking that occurs during microbial treatment.
It is applied in removing contaminants to meet the emission standards limit in the final stage. The method is suitable to the treatment targets, including inorganic ions, nutritive salts, heavy metals, and non-biodegradable organic matters according to the feature of the wastewater.
It mainly removes substances that affect taste, smell, and color, and it disinfects at the same time.
It is excellent in the removal of non-degradable substances and color-causing substances, and is mainly introduced into the dyeing wastewater treatment process.
