Pulp Making by Soda-Anthracite Process
Introduction
Pulp and paper making needs a lengthy process of pulping and bleaching in order to produce quality paper products. In the past, sulfite processes were used in the production of pulp due to a number of advantages, such as good bleaching capabili......
chemical eye burns
Chemical Ocular Burns
Introduction
Chemical ocular burns occur when a person is exposed to any kind of caustic chemical, such as alkalis, acids, solvents, detergents, and bleaches. Ocular burns are serious medical emergencies and can lead to permanent vision loss, if not treated in time. The pur......
chemical precipitant
Chemical Precipitant
Chemical precipitants are compounds that, when mixed with a solution, cause the solution to become cloudy or otherwise change its physical state. Typically, the change is due to the formation of a solid-state precipitate that may be visible to the naked eye. Chemical precipita......
Hydrochloric acid pickling wastewater treatment design
Design of Sulfuric Acid Pickling Waste Solution Treatment
Abstract
The nickel industry is now a major consumer of sulfuric acid. The industrial scale production of sulfuric acid generates a large amount of spent pickling liquid. It is necessary to treat this kind of liquid before returning it to......
