As a result of long-term and industrial tests it was found that Taurit filtrate-sorbent may be used as a filtering material during the drinking water technological processing and improves the organoleptic indicator (odor, taste and sediment concentration) of polluted water to regulatory and engineering requirements.
Since 2003 Taurit has been widely used as a filtering material in waste water treatment facilities, completely or partially replacing traditionally used materials (activated carbon, zeolite, clay, sand, haydite).
Taurit showed itself as a good filtering material with a high technical abrasion resistance and grindability, which does not require annual reloading of the filters.
Analyzing the obtained data on changes in the content of elements in polluted and treated water, the following conclusions can be made:
Taurit effectively, even at low concentrations treats water, removing heavy metals, such as: lithium, magnesium, copper, zinc, strontium, niobium, cadmium, tellurium, mercury and lead.
During processing Taurit saturates silver ion water, thereby disinfecting water, which is another positive aspect when cleaning water with Taurit. Silver is an element of Taurit natural composition.
Taurit filtrate - sorbent:
Nowadays, impact of contaminated industrial wastewater of large metallurgical and chemical enterprises on reservoirs and rivers in cities around the world greatly influences on environment and society. A solution for the problem contributed to development of new expensive filtering materials and sorbents, providing only short-term cleaning of drains. “Koksu” company conducted a number of tests aimed at reduction of the level of industrial environment pollution by offering own-produced alternative low-cost filter material, possessing excellent sorption characteristics to a wide range of organic and inorganic contaminants.
The results of Taurit application in purification of wastewaters of non-ferrous metallurgy and chemical industries showed high efficiency of its application at water treatment plants as well as in filters and permitted the following conclusions:
Disposal of drilling sludge
It is known that during drilling and construction works a so-called drill cutting, which must be subjected to a binding process recycling, inevitably appears. Especially dangerous is the impact on the soil and the environment of oil contained in the oil sludge. It should be noted that today the problem of disposal of drilling waste is studied quite actively, in connection with which specialists offer a variety of ecological solutions that can improve the process of disposal of drill cuttings and make it maximally safe for the environment.
Technology of drilling sludge utilization in oil-production was developed on the base of carbonaceous sorbent-destructor converting the drilling waste into soil of V hazard class. The essence of this technology is application of Taurit based new sorbent-destructor, which is an "incubator" for oil oxidizing organisms and, at the same time, a catalyst of oxidation of organic compounds of different structure. This destructor-sorbent has been tested and has received positive feedback on the effectiveness of its application. The new sorbent is also effective to absorb oil from the soil when spilling and liquidating the oil sludge. Pilot-scale remediation of drill cuttings was conducted. According to the results of an independent biotesting and agrochemical examination, oil products content in the soil decreased by more than 150 times.
In world practice, a number of ways to localize and eliminate anthropogenic mercury pollution such as thermal vacuum processing of mercury-containing waste, use of chemicals, dumping in isolated cemeteries of different designs, screening based on a "slurry wall" and others are applied. Certainly, the main condition for environmental measures is the efficiency of work, exclusion or minimization of the impact of anthropogenic pollution on the environment. Taurit is an environmentally friendly mineral, which is used to shield the surface of sites contaminated by mercury.
In 2003, studies of sorption - desorption properties of Koksu shungite (Taurit) to metallic mercury vapors were conducted on the subject of man-made pollution, on the basis of which it is established that Taurit absorbs metallic mercury vapors; and fine-dispersed Carbonate Taurit possesses best sorption properties.
Taurit grades, possessing high sorption capacity, are characterized by timely stable mercury content after their removal from the desiccators, i.e. irreversible sorption process is observed during 5 months.
The findings suggest the possibility of Taurit application at anthropogenic mercury contamination objects, as an effective absorber layer, excluding the possibility of mercury air pollution, indicating the absence of migration of element vapors into the atmosphere through the thickness of the raw material during the period of studies.
