As a national-level "Little Giant" enterprise specializing in niche sectors, a national-level green factory, and a national-level high-tech enterprise, Fujian ZhanHua Chemical adheres to high standards, continuously investing funds in technological transformation and R&D innovation. Its products feature low energy consumption, high quality, and resistance to caking, with relevant energy consumption indicators exceeding the advanced level of industry standards. As the chairman unit of the China Persulfate Association, Fujian ZhanHua Chemical takes the lead in formulating a number of national standards, industry standards, and group standards for persulfates, holding high discourse power and a leading technological position in the industry.

The occurrence of secondary contamination is often associated with substandard quality of the agents used in the remediation process. Some low-quality agents lack effective control during the production process and may contain unreacted impurities or harmful components. When these substances enter the soil, they not only fail to achieve the expected remediation effect but also become new sources of contamination. In addition, insufficient stability of the agent may also lead to secondary contamination—when environmental conditions change, the agent may decompose inappropriately and release substances harmful to the soil ecosystem.

The hazards of secondary contamination are concealed and long-term. It damages the original physical and chemical properties of the soil, affects the soil's air permeability and water retention capacity, and thereby hinders plant growth. At the same time, contaminants may seep through the soil into the groundwater system or enter the food chain through plant absorption, posing potential threats to the surrounding ecological environment and human health. This traps soil remediation work in a vicious cycle of "remediation - contamination - re-remediation".

The quality of raw materials is the foundation for determining the quality of Sodium Persulfate products. Large-scale manufacturers have established strict screening standards in the raw material procurement process, conducting comprehensive inspections and evaluations of suppliers to ensure that the selected raw materials comply with relevant quality specifications. This eliminates the entry of raw materials with high impurity content or substandard quality into the production process from the source, laying a solid foundation for the subsequent production of high-quality Sodium Persulfate.

Large-scale manufacturers possess mature and professional production process systems, ensuring the stability and purity of Sodium Persulfate through refined production management. During the production of Sodium Persulfate, Fujian ZhanHua Chemical strictly monitors and adjusts various process parameters to avoid product quality degradation caused by process fluctuations. It adopts advanced production equipment and technologies, which not only improve production efficiency but also ensure the consistency of product quality.

A sound quality testing system is an important means for large-scale manufacturers to control the quality of Sodium Persulfate. These manufacturers have established a full-process testing mechanism from raw material warehousing to finished product delivery, equipped with professional testing personnel and advanced testing equipment to conduct strict testing on various indicators of the products. Fujian ZhanHua Chemical has always adhered to the principle of "quality first", strictly implementing international standards in every link from raw material procurement to production processes. It has obtained ISO 9001 quality management system certification and established a sound quality management framework, providing systematic guarantee for the production of high-quality Sodium Persulfate products that are stable, consistent, and meet specification requirements.

Sodium Persulfate produced by large-scale manufacturers has strong oxidizing properties and can efficiently decompose organic contaminants in the soil. During the remediation process, it can react with target contaminants, oxidizing and decomposing them into low-toxicity or harmless small-molecule substances. This significantly reduces the organic pollution load in the soil and improves the quality of the soil environment.

For soil with composite contamination (especially cases where organic matter and heavy metals coexist), high-purity Sodium Persulfate produced by large-scale manufacturers can play an important role under specific conditions (such as combined use with other agents or technologies). Its strong oxidizing property helps degrade the organic matter bound to heavy metals, releasing heavy metal ions and creating conditions for subsequent stabilization treatment.

Compared with low-quality products containing more impurities, high-purity and high-stability Sodium Persulfate produced by large-scale manufacturers can significantly reduce additional ecological risks caused by unknown impurities. Its reaction process is more controllable, and its by-products are clearer, which helps reduce unpredictable negative impacts on soil microbial communities, animals, and plants, thereby improving the overall environmental compatibility of the remediation process.

In the process of soil remediation, guarding against secondary contamination is essential, and high-quality chemical agents are an important cornerstone for safeguarding soil remediation projects. Fujian ZhanHua Chemical has a strict quality control system. Through comprehensive quality control from the source to the end, it ensures the purity and stability of its products, providing a reliable and consistent source of agents for remediation projects and effectively reducing the risk of secondary contamination caused by substandard agent quality. Sodium Persulfate from such large-scale manufacturers, with its excellent quality, has become a trusted choice in the field of soil remediation.
