In the engineering construction, the excavation of foundation pit and the piling of foundation are necessary, and these processes will produce a lot of high concentration of sand sewage. In order to ensure environmental safety, the sand sewage generated by foundation piling must be properly treated before discharge, and the treated mud cake needs to be transported to the designated place for landfill. So, what is the effective treatment method for foundation piling sand?
The foundation pile grouting is mainly composed of kaolin particles, fine sand and bentonite, and its PH value and composition vary from region to region. At present, compared with the sedimentation tank method, natural drying method and traditional machine and equipment treatment, drug flocculation treatment is favored because of its advantages of economic and environmental protection and resource recycling. Therefore, many customers tend to use polyacrylamide (PAM) as a flocculant to treat the foundation pile sand.
As a water-soluble polymer, polyacrylamide has shown excellent performance in sludge treatment. When PAM is mixed with the suspended sludge containing fine mud particles, it can effectively play multiple roles such as flocculation, adsorption, bridging, precipitation and trapping. Specifically, PAM can destroy the stability of the sludge, and promote the sand particles to quickly condense and precipitate from the water to achieve effective separation of the sludge. The separated water can be directly recycled, while the sediment can be further dedried by the filter press, and finally transported to the storage yard or backfilled to the designated area.
YUANBO, as a polyacrylamide manufacturer, is committed to providing customers with full service support and product customization, design and implementation of cost-effective wastewater treatment solutions. We have accumulated rich practical experience in the field of foundation piling mud treatment, and have successfully applied in many project sites, and won high praise from customers. The polyacrylamide chemicals produced by the company are not only cost-effective but also have high molecular weight, which can effectively help customers reduce treatment costs. With deep system knowledge and technical strength, we are able to accurately solve various water environmental problems encountered in the treatment of urban building foundation piling sand slurry, ensuring that customers obtain satisfactory treatment performance.
