sodium hypochlorite


Liquid waste and wastewater, that contain hypochlorites, are formed during the production of chlorine and caustic soda; electrolytic production of magnesium and chlorine; in the production of pulp and paper products etc. Such wastewaters belongs to sub-standard, therefore they are not reused in corresponding technological processes. In accordance with the current normative documents, hypochlorite wastewaters must be disposed of at the local treatment facilities of the enterprises where they are produced.

Investigation of disposal of liquid wastes from olefin production by sodium hypochlorite solutions

It has been studied an effect of ratio between arene and alkene organic compounds, as components of olefin production wastewaters, and sodium hypochlorite, as liquid waste of caustic soda and chlorine synthesis, on their interaction. The organics total content was expressed by a value of chemical oxygen demand. A fundamental possibility of the mutual neutralization was confirmed. Use of a cavitation field significantly reduces duration of the process and the ratio between sodium hypochlorite and organic compounds.

Інтенсифікація очищення стоків ват “Карпатнафтохім” розчинами натрію гіпохлориту в кавітаційних полях

In this paper it was set that in cavitation fields of different power the oxidation rate of organic industrial wastewater by sodium hypochlorite solutions as a liquid waste significantly increases. Influence of main technological factors on this process was found. 
Установлено, що в кавітаційних полях різної потужності швидкість окиснення органічних компонентів промислових стічних вод відхідними розчинами натрію гіпохлориту істотно зростає. З’ясовано вплив головних технологічних чинників на цей процес. Ключові слова: натрію гіпохлорит, органовмісні стоки, очищення, кавітація
