factory waste neutralisation
Answers
Answer:The aim of neutralisation is to modify an acid or base water flow to a neutral pH (approximately 7). The most important objectives are to make the wastewater treatable using biological purification and/or make it comply with discharge criteria. In addition to neutralisations, various pH corrections are also performed for a variety of reasons:
Conditioning, stabilising raw wastewater
Emulsion breaking
Precipitation reactions / resolving precipitation
Checking chemical reaction speeds
Neutralisation generally takes place by adding chemicals directly to the wastewater flow. Thus equipment consists of storage and reaction tanks and a dosage and mixing installation.
To increase pH one uses a leachant (NaOH) or lime milk (Ca(OH)2); to decrease pH sulphuric acid (H2SO4), hydrochloric acid (HCl) or carbon dioxide (CO2) is used. Other acids and bases are also possible (organic acids/bases, for example), but are less commonly used for treating wastewater.
Answer:
Factory Waste of Neutralisation
The Factory waste contain acid if are allowed and kill fishes and other organisms
This factory waste are thus neutralisation
by adding basic substance
