More wastewater treatment plants and industrial enterprises are utilizing volcanic rock filter media. Here are a few suggestions for purchasing volcanic rock filter media that we hope will assist you.
To conduct on-site inspections to assess the capacity for mass processing and stringent quality assurance. Production enterprises usually have their own mines as the source of raw materials, with the quality of the ore from the mine determining the quality of the finished products. There are numerous volcanic rock sites in Datong, with ample supply and good quality materials for forming volcanic rock groups.
2. Genuine volcanic rock filter material manufacturers offer competitive prices, typically requiring payment before shipment. This is due to the fact that processing companies have thousands or tens of thousands of cubic meters of finished products in various particle sizes, eliminating the possibility of fraud or lack of payment security.
3. Calculate the shipping costs by truck or train, as the price of volcanic rock filter material is not high, the shipping fees are generally higher than the product price. Properly calculating shipping costs is a key aspect in saving funds.
4. Set the shipment schedule: approximately 15 trucks can be loaded daily for bulk goods, while for bagged goods (40 tons) loaded onto trains, a one-week advance planning is required to arrange for train cars and short-distance transportation from the production site to the station.
5. Ensure the color of the required product (volcanic rock filter material comes in black and red, with black being preferable), particle size (mm), and packaging requirements. Options include 50 kg woven bags, ton packaging (the stacking density varies with particle size, ranging from 700 kg to 900 kg per package), or loose shipment of volcanic rock filter material, which can save 50 yuan (including packaging and bagging fees).
Volcanic rock filter media is not widely produced in domestic factories due to the limited number of volcanic sites in China. Moreover, the volcanic rock mines capable of processing volcanic rock filter media are even scarcer. Currently, the volcanic rock mines suitable for producing volcanic rock filter media are located in Datong City, Shanxi Province, the Wulung area of Inner Mongolia, and the Zhangjiakou area of Hebei Province. No other areas in China have been found to have volcanic rock ore suitable for processing into volcanic rock filter media.
7. Products must undergo inspection by the Water Treatment Filter Material Quality Supervision and Testing Center of the Ministry of Construction, fully meeting the quality standards for water treatment filter materials. Additionally, processing enterprises should be familiar with the use of volcanic rock filter materials.
