Industrial zero emissions

Zero Liquid Discharge (ZLD) has become a key option for China's future industrial green and low-carbon transformation.

ZLD aims to maximize the recycling of industrial wastewater through comprehensive water treatment technologies, minimizing or even eliminating final liquid waste.

Among the many technological pathways for achieving ZLD, advanced oxidation (UV-AOP) technology plays a crucial role.

UV-AOP technology, due to its ability to generate highly oxidizing hydroxyl radicals (.OH), is particularly suitable for treating difficult-to-degrade, highly toxic organic wastewaters in the chemical industry, such as those from fine chemicals, pesticides, dyes, and pharmaceutical intermediates.

UV-AOP is often used as a deep treatment or pretreatment unit to improve the biodegradability of wastewater, reducing the burden and toxicity impact of subsequent biological treatment.

The electronics manufacturing industry places extremely high demands on process water purity, and ultrapure water (UPW) is an indispensable key material in its production.

UPW has extremely strict control standards (such as SEMI standards) for ions, organic matter (TOC), microorganisms, particulate matter, and dissolved gases.

The wastewater generated during the electronics manufacturing process is complex in composition, some of which is highly toxic. Achieving zero discharge of electronic wastewater places even higher demands on UV advanced oxidation technology.

Ultraviolet Advanced Oxidation (UV-AOP) Applications

UV Disinfection Applications

ZLD Applications:

UV disinfection is often used as a final safeguard before water reuse or in specific treatment steps (such as as an auxiliary means of TOC removal or to prevent biofilm growth).

Ozone is primarily used for deep oxidation (degradation of COD and TOC), decolorization, deodorization, and biodegradability in wastewater. It is also used as a component in certain advanced oxidation processes (such as O?/H?O?).

UV-AOP is a key technology for the decomposition of recalcitrant organic pollutants. It can degrade these stubborn pollutants, thereby improving the treatment efficiency of the entire ZLD system and ensuring effluent quality.

Clear Medium Pressure UV Disinfection System

The ONYX-Clear-SZ in-line medium-pressure UV sterilizer utilizes medium-pressure multi-spectral UV lamps to not only destroy DNA/RNA but also intracellular enzymes and proteins, resulting in more thorough sterilization. It is designed to disinfect and degrade toxic micropollutants in water, including NDMA, 1,4-dioxane, endocrine disruptors (EDCs), pesticide residues, cyanobacterial toxins, GSM (geosmin), and 2-MIB (dimethylisoborneol).

In addition, combining oxidants such as O? and H?O? with UV light, such as UV-O? and UV-H?O? processes, can be used to oxidatively remove recalcitrant substances and organic matter, such as CC14 and polyaminobiphenyls, from wastewater.

MOL Ceramic Plate CD Ozone Generator

The ONYX-MOL plate-type ozone generator features a modular design that allows for block-type assembly based on gas production capacity, resulting in a compact structure.

Utilizing high-purity aluminum-based ceramic electrodes and a highly resistant micro-arc oxidation process, the system delivers stable and reliable performance with an ultra-low attenuation rate. Uniform micro-gap high-frequency discharge delivers energy savings of 20-35%. The ozone concentration is adjustable from 0 to 240 mg/L, saving up to 40% oxygen.

The power-on auto-start design eliminates the need for manual intervention. It features self-diagnosis during operation, error handling, and intelligent recovery. Edge computing and cloud service coordination are integrated for operational status.

UV-Fenton

Photo-Fenton is an advanced oxidation process (AOP) that combines the traditional Fenton reaction with photochemical excitation. It significantly enhances the oxidation capacity of the Fenton system through ultraviolet irradiation, achieving efficient mineralization of difficult-to-degrade organic pollutants. Its core principle is to utilize light energy to accelerate the circulation of iron ions and promote the generation of hydroxyl radicals (·OH). It offers significant advantages in reducing iron sludge production, increasing reaction rates, and lowering operating costs. It is particularly suitable for treating high-concentration, highly toxic industrial wastewater.

UV-AOP Advanced Oxidation

Ultraviolet Advanced Oxidation Process (UV-AOP) is an environmentally friendly technology that uses ultraviolet radiation to trigger oxidation reactions. Its core principle is to use UV light to excite oxidants to generate highly oxidizing free radicals, which in turn degrade organic and inorganic pollutants. UV-AOP is characterized by high efficiency, environmental friendliness, and zero secondary pollution. UV-AOP systems can be categorized into various types depending on the type of oxidant, the most common of which include UV/hydrogen peroxide, UV/ozone, and UV/chlorine.

ONYX-Clear-SZ-AOP can serve as the UV light source for UV-AOP. This UV-AOP system can be used to degrade toxic micropollutants such as nitrosodimethylamine, 1,4-dioxane, endocrine disrupting chemicals (EDCs), pesticide residues, cyanobacterial toxins, GSM (geosmin), and 2-MIB (dimethylisoborneol).
