ALUMINIUM DROSS....

Aluminium dross is transported in large-volume sacks to our plant and they are stocked in the closed covered stock house. These sacks are transported to the own technological line. The mechanical final sorting of input into several fraction is as the first operation. Roughest metal content fraction is sold for product RECAL. The middle-size fractions are finish-milled and repeatedly sorted. Finest fraction is used for own input treatment. This treatment consists in catalytic decomposition of input material under the higher temperature and pressure with water, in under the circumstances multi step heated reactors. Generating gaseous products with hydrogen, methane and ammonia content are exhausted to the combustion chamber and generated heat is used for heating of decomposition process or for evaporation of water from brines. The brine is generated from the separation of solid and liquid phase of produced sludge from desintegrative reactor. Further the solid phase is washed multiply; thereby it gets clear of rest water-soluble materials to the required level. An inert product, free of hazardous characters with aluminium oxide, aluminium hydroxide, aluminium oxide-hydroxide content and with accompanying elements (silicium, magnesium, calcium, ferrum) is generated by input material decomposition and additional washing. Inert material is mixed with cementing material and additional raw materials and pelletizing of this inert material is made. Pellets are finish-dry at required minimal moisture, dust parts are sorted and final product is dispatched. Liquid phase with water-soluble soil content evaporates. Washing water is generated by cooling of exhausted waste vapour and final washing water is used for decomposition water to the reactors water. Brine concentrated solutions are put into crystallization. Generated crystals get dry, are mixed with appropriate components and the result is covering or refining soils, which are used on aluminium metallurgy (e.g. EKOSOL B or ECOSAL).

The technology is specialized to use all waste materials, to be wasteless. Solid phase is used for products named ALCATEN, ALMAGEN and other products are in process; these products are used among others as the substitution of fluor-spar for ferrous metallurgy.

Our company KVS EKODIVIZE a.s. has all legislative premises for operation with objective technology, regulated by Law of Czech Republic including permit for import of hazardous waste assigned category from abroad.
