The factory is considered one of the important solutions for effective use of currently available sea sand resources.
The plant uses Phan Thanh sand cleaning and sifting technique developed by Vo Tan Dung for rinsing sand. Dung authorized Viet Sand Cleaning and Sifting Company and Kim Thuy Lam Trading Service JSC to install the technology.
The technique uses water pressure to cut the structure of sea sand and remove salt and organic impurities, then filters it again to extract sand that could be used for building projects.
With a maximum capacity of 200 cubic meters per hour, the plant can make beach sand finer by washing and sifting it and separating the impurities. The final sand products can be used to make concrete and mortar for construction and to serve other industrial activities.
Earlier this year, the technology creator had set up a sand cleaning and sifting machine to pilot its operations with inspections from experts of the Institute of Concrete Technology at the Ministry of Construction. The test results showed that the sea sand taken from Phu Quoc after being processed by Phan Thanh technology met the standards for construction sand.
Vo Tan Dung expressed his hopes the sand cleaning technique will contribute to cooling down the construction sand fever that has been raging across Vietnam, leading to illegal sand mining in rivers and coastal areas.
At the same time, the factory contributes to promoting the advantages of using local raw materials, reducing the cost of sand and transporting sand in construction investment, thus improving the efficiency of using the project.
Therefore, the factory will initially solve the demand for construction sand for projects that are deployed on Phu Quoc island, saving on the cost of transporting river sand to the island, contributing positively to solving severe land erosion due to a shortage of sediments in the Mekong Delta.
