In March 2023, Zeofixer®, a silicon-based phosphorus sequestering agent, was applied to Lake Ziyang in Wuhan for phosphorus reduction.
Location of Lake Ziyang
Ziyang Lake is located in the south of Snake Mountain in Wuhan, Covering an area of about 20 hectares.
Application on Lake Ziyang
The pre-treatment total phosphorus concentration in the water body was 0.115mg/L.
According to the requirements of the local environmental protection bureau, the total phosphorus in the water body should be reduced below 0.05mg/L after carrying out the application.
In March 2023, Zeofixer®, a silicon-based phosphorus sequestering agent, was applied to Lake Ziyang to reduce the phosphate concentration in the overlying water and permanently “cap” the sediment.
Result of the Application
Sixty days after the application, the total phosphorus concentration in the overlying water had stabilized at 0.04-0.05mg/L (Removal Rate: 65%), which achieved our customer’s needs.
Comments from Our Customer
“Zeofixer® not only makes the project quality meet our expectations, but also saves at least half of the material purchasing budget for phosphorus sequestering agent.” said Mr. Luo, GM of ORCA (Wuhan) Intelligent Technology, who is the owner of this project and used to be a user for conventional LMB.
“The dosage is halved since the active ingredient is doubled, zeofixer® makes the dosing more efficient, compared with common LMB.” said Mr. Wang, project manager of ORCA (Wuhan) Intelligent Technology.
