Russia ’s Southern Ural State University has developed a mixed adsorbent that can clean sewage, which can efficiently adsorb heavy metals from sewage. At present, this adsorbent has passed the test and obtained a patent. The adsorbent has a large surface and highly open porous structure. It is composed of a particulate heat-treated mixture formed of silicate, hydromica, and volcanic glass, which greatly improves the ability to suck heavy metals from sewage. Dmitri Ulrich, director of the University ’s Institute of Architecture and developer of adsorbents, said: “The composition of the mixture is selected to ensure that the filtration rate of the cleaned sewage is not lower than the speed specified by the technology. An important indicator of the adsorption process It is the contact time between the adsorbent and contaminated sewage, so depending on the selected ratio, the structure of the adsorbent ensures the optimal porosity of the system. " Ulrich claims that the new adsorbent can absorb heavy metal salts (copper, lead, zinc), petroleum and petroleum products, radionuclides, toxins, pesticides and other toxic compounds. Currently, researchers are seeking industrial partners-mining companies and metallurgical companies interested in clean sewage. Heavy Bamboo Veneer SPC Flooring is the synthetic flooring of heavy bamboo veneer and stone plastic plank. Heavy bamboo veneer is more fine than common bamboo veneer, it is a kind of high density bamboo veneer, generally, it is made of high-quality bamboo over five years old, with the stone plastic core on the tenacity, high stability, health and environmental characteristics, many customers who worry that pure bamboo flooring is not durable enough but love it so much ,have a better choice.
