Environmental protection technologies in the production of sodium hypochlorite

Abstract

Today, regulatory and environmental acts have tightened requirements for the quality of drinking water. Sodium hypochlorite, in comparison with other chlorine-containing agents, is the least scarce and fairly cheap detoxifier. Due to its high antibacterial activity and a wide spectrum of action on various microorganisms, sodium hypochlorite is listed first in the list of chlorine substitutes, in addition, it is much cheaper and does not have such a strong corrosive effect on pipelines. Also important is the fact that the cost of sodium hypochlorite is 2.5–3 times cheaper than liquid chlorine. However, in the production of sodium hypochlorite, absorption gases with a chlorine content may enter the atmosphere.
