Company Introduction

Asia Symbol (Shandong) Pulp and Paper Co., Ltd. is a world-leading vertically integrated pulp & fiber enterprise under Singapore-headquartered RGE Group. RGE Group operates across forestry, high-grade paper, green fibers, palm oil processing, clean and new energy worldwide, with presence in Indonesia, China, Brazil, Canada, Spain and beyond. It owns total assets over US$35 billion and more than 80,000 employees globally.

Background Shouxin Environmental Protection

The client optimized suppliers for its air-flotation process to eliminate traders and find a capable polyacrylamide manufacturer with stable quality. The client pointed out that previous suppliers conducted small-scale tests merely based on sedimentation principles with rudimentary equipment, resulting in unprofessional and inaccurate model selection.

Solution

As the global polyacrylamide brand with stable quality, our company is the Chairman Unit of the Polyacrylamide Industry Association. Mr. Gu Shiyou, Chairman of the Association, praised "Shouxin as the only company to win this honor without its own factory". This innovative industry model perfectly matches the client's requirements.
Upon receiving the client's demand, leveraging our extensive product portfolio with over 100 PAM models available, we immediately organized a professional technical team to visit the site with specialized selection equipment. Drawing on our rich experience in serving pulp and paper enterprises, we carried out multiple rounds of on-site verification and selection to identify the most suitable product models .

Result

The client highly praised that "Shouxin is the only supplier capable of simulating onsite working conditions with professional selection equipment to achieve flotation floc formation for accurate model screening".

After large-scale model selection, the optimal model was successfully identified. Supported by Shouxin's formula R&D system focused on product quality stability, academician Shen Yinchu has deeply participated in our core technology development and quality control system construction. He has provided systematic technical guidance to improve product stability, ensuring steady performance under complex application scenarios. We have effectively addressed the client's practical needs by not only selecting the perfectly matched model, but also delivering longterm stable onsite treatment performance.

Test Data Record Sheet

Test Conditions / Detection Indicators	Shouxin No.7 Polyacrylamide	Other Brands Used by the Client	Comparison Conclusion
Test Water Sample Volume (mL)	500	500	Same Conditions
PAM Concentration (%)	0.5	0.5	Same Conditions
PAM Dosage (mL)	6	6	Same Conditions
PAM Consumption (ppm)	6	6	Same Conditions
Floc Size	Larger flocs with dense and compact structure	Smaller flocs with loose structure	Shouxin shows significant advantages
Flotation Rate	Rapid	Slow with higher residual carryover	Shouxin shows significant advantages
Supernatant Turbidity (NTU)	23.6	31.8	Shouxin shows significant advantages
Overall Evaluation	Treatment performance fully met operational requirements while reducing chemical consumption and operating costs	Higher dosage was required to barely achieve target treatment performance, resulting in increased operating costs	Under the same dosage conditions, Shouxin No. 7 Polyacrylamide demonstrated significantly superior overall treatment performance compared with competing products. It can directly replace the existing chemical program while optimizing both operational efficiency and cost control.

Clear Water Volume Comparison

Under the same time condition, Shouxin No.7 forms a noticeably thicker supernatant layer than client's existing on-site brands. It achieves faster flocculation, more efficient separation between flocs and water, and delivers a higher final yield of clear water.

Flotation Volume Rate Comparison (mL/s)

Shouxin No.7 delivers a faster initial reaction and quickly generates floatable flocs. This allows it to process larger volumes of wastewater in equal time. It also achieves a higher peak than client's existing on-site brands, boasting the best maximum flotation efficiency and optimal floc separation performance.
