Nanozymes for Treatment of Emulsion Wastewater

Emulsion wastewater contains mineral oil (or vegetable oil), waste soap, cutting agent, coolant, lubricant and other harmful substances. Its chemical composition consists mainly of acrylic acid, formaldehyde, ethyl acrylate, and other organic matter, mainly derived from the production and use of everyday chemical products. These organic substances have high concentrations, stable chemical properties, difficult degradation, complex composition, and poor biochemical properties. However, due to structural barriers and electrostatic repulsion between the droplets, it is difficult to separate the emulsion wastewater by conventional processes.

Nanozymes have received increasing attention due to their ability to not only achieve efficient demulsification, but also to effectively recover demulsifies. Creative Enzymes provides a variety of nanozymes for emulsion wastewater treatment, helping our customers worldwide in the nano-zymes field.

Treatment of Acrylic Acid in Wastewater with Nanozymes

• Acrylic acid is the main component in emulsion wastewater and is difficult to degrade due to its large molecular weight.
• From the perspective of substrates, the current studies on the photocatalytic degradation of organic matter by nanozymes are generally small molecules, while the degradation of macromolecular organic matter by nanozymes requires the modification of other metal nanozymes.
• Creative Enzymes uses precious metal silver doped nanozymes as photocatalysts, to study the photocatalytic degradation of common organic macromolecular acrylic acid in wastewater.
• We also prepare Fe nanozymes for the degradation of acrylate emulsion wastewater with high removal efficiency.

Treatment of Formaldehyde in Wastewater with Nanozymes

• Activated carbon fiber (ACF) is an excellent adsorption material, but in practical application, the limited adsorption capacity of organic pollutants such as formaldehyde, the need for activation after adsorption saturation, and the low surface tensile strength of forming materials restrict its wide application.

• We use ACF nanozyme composite with simulated enzyme catalyst and nano-silver fungicide, which can be widely used in formaldehyde removal.

Treatment of Emulsified Oil with Nanozymes

• Creative Enzymes prepares Fe₃O₄ nanozymes that can demulsify emulsified oil well under acidic and neutral conditions.
• We synthesize a novel amphiphilic composite by modification with 3-aminopropyl triethoxysiloxane (APTES) and graft Fe₃O₄ nanozyme on the surface of APTES, which has good demulsified effect and excellent salt resistance.
• The chitosan (CS) is coated on the surface Fe₃O₄, so we synthesize a new environmental protection material, which is used in the treatment of emulsified oil wastewater with good effect. The new synthetic material showed almost no effect on the demulsification performance after eight cycles.
