Study Notes
Calculating Annual Quantity of Zinc Sulfate
- The annual quantity of zinc sulfate handled is calculated by summing the quantity used, produced, and imported.
Activated Sludge Treatment
- The removal efficiency of the activated sludge treatment mentioned is not specified.
Calculating Quantity Shipped in Products
- The quantity shipped in products is calculated by multiplying the quantity of products shipped by the concentration of zinc sulfate in the products.
Conversion Factor for Zinc Sulfate
- The conversion factor from zinc sulfate (7 hydrate) to zinc represents the weight ratio of zinc to zinc sulfate (7 hydrate) in the calculation.
Landfill Designation
- The purpose of designating landfills as 'stable' or 'administrated' by the Law is to differentiate landfills based on their management and environmental impact.
Reporting Exemption
- Reporting is not required if waste is sold for recycling because it is considered a beneficial reuse.
Process Flow Example
- In the process flow example, the main destination of Zinc sulfate heptahydrate is the production of zinc oxide.
Calculating Releases and Transfers
- The purpose of calculating releases and transfers in typical processes is to quantify the environmental impact of the process.
Calculating Transfers of Chemical Substances
- The formula used to calculate the transfers of chemical substances contained in waste color and broke is not specified.
Calculating Maximum Potential Releases
- The step that involves calculating the maximum potential releases to the environment is the release estimation step.
Calculation for Quantities Shipped in Products
- Part of the calculation for quantities shipped in products includes the quantity of products shipped and the concentration of zinc sulfate in the products.
PRTR
- In the calculation method provided, 'PRTR' stands for Pollutant Release and Transfer Register.
