Descrição do serviço

Wastewater which contains chromium and other heavy metals is classified as high toxic wastewater. For this type of wastewater is required qualitative and effective treatment. There are different chromium removal methods such as chemical precipitation, adsorption and biosorption, reverse osmosis, ion exchange, electrodialysis, photo-catalysis. We offer to use breakthrough technology – electromagnetic vortex layer with rotating ferromagnetic particles (AVS-100 or Intensifier of Technological Process). As we already noted in our previous articles, offered method is very effective and allows reduce reagent consumption in 1.5-2 times, reduce energy consumption is 2 times and decrease working area of treatment facilities in 10-15%. Typically wastewater which contains chromium compounds treated in 2 stages. First we need change hexavalent chromium Cr6+ to trivalent chromium Cr3+. As result we need obtain non-toxic materials. Engineers from PC GlobeCore have investigated the effectiveness of AVS usage in following versions: I – sterilization of chromium-containing wastewater by reduction hexavalent chromium to trivalent chromium, II – combined neutralization of chromium-containing and acid-base wastewater with simultaneous purification from heavy metals ions. On the basis of performed investigations and production experiments of AVS application for wastewater treatment, we offered and implemented manufacturing schemes of wastewater treatment on different treatment facilities. The wastewater with metal hydroxides (after processing in AVS unit) enters the settling tank for defecation and then – the sewerage or the water recycling (to the shopfloors for engineering purpose). The sludge from settling tank is dewatered by vacuum filters. Application of AVS unit allows obtaining the quality of treatment lower than maximum permissible concentration, reduce reagent consumption in 1,5-2 times, reduce energy consumption in 2 times and decrease working area of treatment facilities in 10-15%.
