Technology of using powdered activated carbon: the experience of SUE «Vodokanal of St. Petersburg»

Summary

In the context of progressive urbanization of territories, increasing anthropogenic impact on the environment, global climate change, high probability of environmental and manmade disasters, depletion of natural resources and the current demographic situation, the risk of reducing the level of safety of drinking water supply increases. At present, the threat of probable pollution of water sources due to possible terrorist sabotages or manmade disasters has significantly increased. There is a potential hazard of detecting toxic chemicals in intake water. Surface sources of water supply are subject to significant fluctuations in water quality owing to the impact of natural and anthropogenic factors. One of the key tasks to be considered is possible prompt and effective neutralization of the water source pollution with organic substances of natural and artificial origin in order to eliminate supplying water of non-normative quality to the consumers. The feasibility of increasing the reliability of sorption technologies alongside with introducing production processes that meet modern requirements has been estimated.
