- 11. What is pyrolysis and how is it used to treat hazardous waste materials?arrow_forwardAn industry wants to locate a chemical plant in your city, they expect to generate 25,000 gal/hr of waste containing 800 mg/L of BOD wastes (reactive) and 15,000 mg/L of inert (non-reactive) materials. The industry wants to recycle 300 gal/min (containing 20 mg/L BOD and 400 mg/L of salts) of discharge (effluent) from the municipal wastewater treatment plant to dilute their waste to 6,000 mg/L of inerts prior to pre-treating the wastes on their own property. If the rate constant for the first order degradation of BOD5 to be 0.75/hr, how big must the reactor be to treat the BOD entering the reactor to 200 mg/L?arrow_forward47.

- They both have their advocates and detractors. On one of the flyers (printedon paper) they said:Plastic bag does not emit toxic fumes when properly incinerated. When burned in waste-to energy plants, the resulting by-products from combustion are carbon dioxide and water vapor. The bag is inert in landfills, when it does not contribute to leaching, bacterial or explosive gas problems. The bag photo-degrades in sunlight to the point that normal environmental factors of wind and rain will cause it to break into very small pieces. Thereby addressing the unsightly litter problemQ: Is all of it true?

- Write briefly about stages of Municipal solid waste process collection in an urban area.arrow_forwardExplain why waste to energy incinerators do not burn used tires.arrow_forwardCan I get a thorough step by step for the following question? The US EPA requires hazardous waste incinerators to meet a standard of 99.99% destruction and removal of organic hazardous constituents injected into the incinerator, which is referred to as "four nines DRE". The efficiency is calculated by measuring the mass flow rate of organic constituents entering the incinerator and the mass flow rate of constituents exiting the incinerator stack, as shown in Figure 1. Draw a mass-balance diagram and determine the allowable quantity of contaminant in the exit stream if the incinerator is burning 1.2000 g/s of hazardous constituents. If the incinerator is 96% efficient in destroying the hazardous constituents, what scrubber efficiency is necessary to meet the EPA standard?arrow_forward
