Corona discharge with a discharge current of a few hundred microamperes can blow out a small candle flame within about 1 cm of a discharge point. A pinwheel, with radial metal spokes and pointed tips bent to point along the circumference of a circle, can be made to rotate if energized by a corona discharge; the rotation is due to differential electric attraction between the metal spokes and the space charge shield region that surrounds the tips. Corona discharge A corona discharge is an electrical discharge brought on by the ionization of a fluid such as air surrounding a conductor that is
Wastewater discharge standards in Latin America skin and also several problems in the respiratory system. This is a component present in the industries of chemicals, leather, textile, electro painting among others. The minimum requirement for this element is presented in Bolivia (0.1 mg/lt), and the maximum is presented in Mexico(0.75 mg/lt). Despite Brazil being one of the main producers of chromium, it doesn't have a maximum limit as do other countries. Wastewater discharge standards in Latin America Wastewater discharge standards protect water sources from pollution and mismanagement. Each country in Latin America has its own set of standards, and these vary according to types of water
