Which company is strong at cutting fluid cleaning? McLain is here to help! I. Wastewater Treatment Methods for Water-Based Cutting Fluids: There are four main categories: physical treatment, chemical treatment, biological treatment, and incineration. 1) Physical Treatment: The purpose of this method is to separate suspended solids (such as chips, grinding swarf, fine powders, oil particles, and other substances with particle diameters greater than 10² m) from the aqueous solution. There are three primary approaches: Cutting Fluid Wastewater Treatment Methods – Baidu Search (baidu.com) Settling separation and flotation separation based on the density difference between suspended solids and water. Filtration separation using filter media. Centrifugal separation using centrifugal devices. 2) Chemical Treatment: This involves treating fine suspended particles or colloidal particles (substances with particle diameters ranging from 0.01 to 10² m) that were not separated by physical methods, or chemically converting harmful components in the wastewater into harmless substances. There are four main methods: Coagulation method: Using inorganic coagulants (such as polyaluminum chloride and aluminum sulfate) or organic coagulants (such as polyacrylamide) to promote the coagulation of fine particles and colloidal particles. Oxidation-reduction method: Employing oxidizing agents like oxygen and ozone, or electrochemical oxidation-reduction reactions, to treat harmful components in the wastewater. Adsorption method: Utilizing activated carbon or other active solids to adsorb harmful components in the wastewater onto the solid surface, thereby achieving treatment.

I. Water-based Cutting fluid Wastewater treatment methods:
There are four main categories: physical treatment, chemical treatment, biological treatment, and combustion treatment.
1) Physical treatment: Its purpose is to separate suspended solids in the coolant (such as chips, grinding swarf, powder, oil particles, and other substances with particle diameters greater than 10² m) from the aqueous solution.
There are three methods as follows: Cutting Fluid Wastewater Treatment Methods – Baidu Search (baidu.com)
Settling separation and flotation separation based on the specific gravity difference between suspended solids and water. Filtration separation using filter media. Centrifugal separation using a centrifugal device.
2) Chemical Treatment: This involves treating fine suspended particles or colloidal particles—particles with diameters ranging from 0.01 to 10² meters—that have not been separated by physical methods, or chemically treating harmful components in wastewater to render them harmless.
There are the following four methods:
Coagulation is a process that uses inorganic coagulants (such as polyaluminum chloride and aluminum sulfate) or organic coagulants (such as polyacrylamide) to promote the aggregation of fine particles and colloidal particles. Oxidation-reduction treatment involves using oxidizing agents like oxygen and ozone, or electrochemical redox reactions, to remove harmful components from wastewater. Adsorption is a method in which active solids, such as activated carbon, are utilized to adsorb harmful substances from wastewater onto their surfaces, thereby achieving the desired treatment effect.
