High purity (usually requiring ≥99%) is the core guarantee for Sodium Persulfate to generate sufficient sulfate radicals and achieve efficient oxidative degradation. Excessively high levels of impurities (such as iron and heavy metal ions) not only consume oxidants and reduce reaction efficiency but may also introduce new environmental risks. Meanwhile, Sodium Persulfate is prone to moisture absorption and caking, so it is necessary to select products with tight packaging and easy storage, and store them in a dry environment to ensure their chemical activity remains stable until use.

Sodium Persulfate needs to be activated to exert its strongest oxidative efficiency. Different site conditions (such as pH value, temperature, and groundwater quality) are suitable for different activation methods (such as thermal activation, iron activation, alkali activation, etc.). Therefore, when selecting products, it is necessary to combine the designed remediation process, evaluate its compatibility with specific activation methods and reaction efficiency, and ensure efficient free radical generation under on-site conditions.

In addition to purity, the active oxygen content of Sodium Persulfate is a key performance indicator, which directly determines the treatment efficiency of the oxidant. A reliable supplier should be able to provide a Certificate of Analysis (COA) for each batch of products to ensure batch consistency of key indicators (such as purity and active oxygen content). It is recommended to conduct small-scale tests before large-scale application, using on-site actual soil/groundwater samples to verify the product’s reactivity and removal rate of target pollutants, and use data to guide model selection and dosage design.

As a manufacturer of high-efficiency oxidative Sodium Persulfate raw materials, Fujian ZhanHua Chemical has become a high-quality partner for petroleum-contaminated site remediation projects by virtue of multiple advantages.

ZhanHua Chemical has a complete Sodium Persulfate production system, forming a standardized process closed loop from raw material procurement to production and processing. Its annual production capacity of Sodium Persulfate reaches 50,000 tons, ensuring continuous product supply. Meanwhile, the company has dedicated hazardous chemical warehouses in Guangzhou, Suzhou, Chengdu, and Wuhan, which can provide sufficient raw materials in a timely manner according to the needs of remediation projects, avoiding project delays caused by raw material shortages.

Quality control is the core focus of the company’s production process. Fujian ZhanHua Chemical has established a full-process quality inspection mechanism. Every step, from incoming inspection of production raw materials, real-time monitoring during production, to multi-dimensional inspection of finished products before leaving the factory, follows strict standards. Through systematic quality control, it ensures that the produced Sodium Persulfate consistently meets requirements in key indicators such as stability and purity, and can adapt to the raw material quality needs of petroleum-contaminated site remediation, providing reliable support for remediation effects.

In the remediation of petroleum-contaminated sites, the concept of ecological environmental protection needs to run through the entire process—raw materials must be environmentally friendly, and the raw material production process must also be green. As a "National-Level Green Factory", Fujian ZhanHua Chemical always practices the concept of green production when producing high-efficiency oxidative Sodium Persulfate. It optimizes production processes to reduce energy consumption, and at the same time, standardizes the treatment of waste generated during the production process to reduce the impact on the surrounding environment. This green production model can not only provide high-quality raw materials for remediation work but also avoid additional environmental burdens caused by the raw material production process, further ensuring the ecological value of remediation work.

Choosing a high-efficiency oxidative Sodium Persulfate raw material manufacturer with strong strength and high-quality products is the key to the steady progress of petroleum-contaminated site remediation. Relying on its mature production system, strict quality control, and green production concept, Fujian ZhanHua Chemical provides high-quality raw materials and comprehensive support for remediation projects, contributing to the improvement of the ecological environment and the restoration of soil functions.
