Brush discharge plastics. The ability of an electrical discharge to cause an explosion in flammable atmospheres is measured by the "effective energy" of the discharge. The effective energy of brush discharges is 10-20 mJ, much larger than that of corona discharges 0.1 mJ. Therefore, brush discharges are considered an explosion hazard, while corona discharges are not. Brush discharges can occur from charged insulating plastics (for example polythene) to a conductor. Brush discharge A brush discharge is an electrical disruptive discharge similar to a corona discharge that takes place at an electrode with a high voltage applied to it, embedded in a nonconducting
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
