SINOKLE Heterogeneous Ozone Catalyst: Redefining the Cost-Effectiveness Frontier of Water Treatment Through Innovation

1. The cost dilemma facing the water treatment industry

In advanced industrial wastewater treatment, ozonation has become a mainstream choice thanks to its high efficiency and freedom from secondary pollution. However, synthesising conventional homogeneous catalysts requires high-quality raw materials, sophisticated synthesis equipment and strict control of synthesis conditions, all of which raise catalyst preparation costs.

In addition, catalyst synthesis may generate large amounts of waste, and disposing of it incurs further costs. Although heterogeneous ozone catalysts can be recovered and reused, the cost of recovery and reuse in practice cannot be ignored either.

Catalysts may deactivate during reaction through adsorption, deposition and other mechanisms and require regeneration. Regeneration not only consumes large amounts of energy and chemicals but may also affect the catalyst's structure and performance, reducing reuse efficiency.

The heterogeneous ozone catalyst series developed by SINOKLE Environmental through a cross-disciplinary integration of materials science and reaction engineering achieves a dual breakthrough in treatment efficiency and economic benefit.

2. Understanding the technical cost advantages

1) Material innovation

The heterogeneous ozone catalysts developed by SINOKLE use silicon-aluminium materials such as natural clay, kaolin and fly ash. Compared with costly, difficult-to-prepare carriers such as molecular sieve zeolites and carbon nanotubes, they are inexpensive and widely available.

In terms of active component design, SINOKLE's heterogeneous ozone catalyst is doped with core-shell structured nanometals (such as composite oxides of Fe@C, Mn-Ce and other metals). Core-shell catalysts can exploit their special lattice strain and ligand effects to optimise the geometric and electronic properties of the surface shell metal.

The lattice strain in this structure arises from lattice mismatch between the metal core and the shell, can be maintained within a few atomic layers and significantly influences the electronic structure of the shell metal, greatly tuning the catalyst's catalytic performance.

Second, doping can further regulate and optimise the performance of core-shell catalysts. Doping with suitable ions can improve the shell's oxygen uptake and conduction capability or other catalysis-related properties. For example, in solid oxide fuel cell research, doping with transition metals such as Ce and Ga improves the oxygen ion conductivity of the catalyst particle shell material, thereby enhancing catalytic performance.

Moreover, doping of core-shell structured nanometals helps prevent metal agglomeration and improves catalyst stability and dispersion. During catalytic reaction, dispersed metal ions help organic matter convert into nanostructured carbon during high-temperature carbonisation, which in turn facilitates electron transport and the catalytic reaction, providing strong support for the development of new, highly efficient catalysts.

2) Significant energy savings

3. Key benefit points:

1) Extended catalyst life

The heterogeneous ozone catalyst independently developed by SINOKLE has a service life of more than five years, far exceeding the industry average of 2-3 years. This significantly extended life means less frequent replacement and lower maintenance costs. At the same time, the catalyst's high efficiency, stability and long life ensure continuous, highly efficient operation of the wastewater treatment process, improving overall treatment efficiency.

2) Sludge reduction and hazardous waste cost savings

Using a heterogeneous ozone catalyst significantly reduces sludge generation. During catalysis, the catalyst effectively promotes ozone decomposition to produce more hydroxyl radicals. These radicals have extremely strong oxidising power and efficiently degrade organics, thereby reducing sludge formation.

In addition, the catalyst exists in solid form and separates easily from water, effectively reducing catalyst loss and secondary pollution. More importantly, because of the catalyst's stability and long life, the hazardous waste disposal costs associated with metal leaching from catalyst replacement are reduced - estimated at CNY 500,000-800,000 saved each year.

3) Automation compatibility and lower labour costs

SINOKLE's heterogeneous ozone catalyst supports linkage with intelligent dosing systems, enabling automated control. This makes catalyst dosing and adjustment more precise and efficient and reduces the complexity and error rate of manual operations. Automation compatibility also reduces the need for manual involvement, lowering labour costs.

It is estimated that, with intelligent dosing system linkage, labour costs can be reduced by more than 60%. This not only improves work efficiency but also lowers operating costs, providing strong support for the long-term stable operation of wastewater treatment plants.

4) Contribution to carbon reduction

Through energy savings and sludge reduction, SINOKLE's ozone catalyst achieves a notable carbon reduction effect in wastewater treatment. Specifically, carbon emissions are reduced by 1.2 kg CO2 per tonne of water treated. This achievement not only eases the environmental burden but also aligns with the global trend of carbon reduction, earning enterprises a strong environmental image and social responsibility profile.

5) Resource recovery

After SINOKLE's ozone catalyst reaches the end of its service life, the metal components in the spent catalyst retain high recovery value. The recovery rate exceeds 90%, meaning most precious and transition metals can be effectively recovered and reused. This not only lowers the cost of spent catalyst disposal but also achieves resource recycling, in line with the requirements of green chemistry and sustainable development. Through resource recovery, enterprises can further reduce costs and improve economic returns while reducing demand for virgin resources - a positive contribution to environmental protection.

4. Redefining the cost-effectiveness frontier

Through the technical path of high-activity component design plus long-life stability engineering, SINOKLE's heterogeneous ozone catalyst has successfully compressed the overall cost of water treatment to 70%-80% of the industry average. We provide not only catalyst products but also whole-life-cycle cost optimisation solutions, helping customers achieve both environmental compliance and economic benefit.
