### Environmental Science: Hazardous Waste Management#### 10. What is needed for bioremediation techniques to work on a hazardous waste spill?- **Microorganisms:** Appropriate microbes that can degrade pollutants.- **Nutrients:** Essential nutrients to support microbial activity.- **Environmental Conditions:** Optimal temperature, pH, and oxygen levels.- **Containment:** Proper containment systems to prevent the spread of waste.#### 11. What is pyrolysis and how is it used to treat hazardous waste materials?- **Definition:** Pyrolysis is a thermal decomposition process that occurs in the absence of oxygen.- **Application in Hazardous Waste:** - Converts hazardous organic materials into safer byproducts such as gas, oil, and char. - Reduces volume and toxicity of hazardous waste. - Can break down complex chemical compounds, rendering them harmless. #### 12. What conditions are adverse to the use of phytoremediation?- **Extremely Polluted Soils:** High concentrations of pollutants that can be toxic to plants.- **Unsuitable Climate:** Extreme weather conditions that impact plant growth.- **Poor Soil Quality:** Lack of necessary nutrients for plant growth.- **High Contaminant Mobility:** Fast-moving contaminants that exceed the plant's uptake rate.- **Site Accessibility:** Areas that are difficult for plants to colonize or where planting is not feasible.

Draw a complete process flow diagram for a conventional filtration drinking water treatment plant, labeling each component and indicating its purpose (what it is designed to remove or how it affects removal in subsequent processes). Disinfection by-products: why are they a problem, how are they formed, and how does a conventional filtration plant minimize their formation? The purpose of coagulation and flocculation is to prepare colloidal particles for removal from water or wastewater by a downstream process of settling and/or filtration. The coagulants that are commonly used have two different functions that you should explain. Explain how (the dreaded chemistry) the addition of alum decreases alkalinity and tends to lower the pH of the treated water. (you may want to have a separate slide or graphic to help you explain this). Make sure to discuss how the mixing systems differ between the coagulation (rapid mix) and flocculation (slow mix) steps in the process. Talk about the…

An industrial waste with a flowrate of 110 L/min contains 40 mg/L of zinc. Calculate: 1.) the pH required to maintain a zinc concentration of 2.6 mg/L (EPA's industrial limit for discharge into a sanitary sewer), and 2.) the dose of hydrated lime (Ca(OH)2) required (g/min).
Your organization has been hired to provide a water treatment process or device toremove toxic Chromium 6 [Cr(VI)] from water emanating from an underground source.Your organization has developed a treatment process that removes most of the Cr(VI)from the water to a residual concentration of 0.05 mg/L which is an acceptable level inline with the World Health Organisation. The underground water flows at 40 m3/h andhas Cr(VI) concentration of 100mg/L. The effluent flow rate is 97% of the influent flowrate, and the remainder of the water is discharged as wastewater. Calculate theconcentration of Cr(VI) in wastewater.

ANSWER QUESTION 5-23
A waste water plant produces 1000 kg of dry solids per day at a moisture content of 95%. The solids are 70% volatile with a specific gravity of 1.05 and the remaining are non-volatile. Find the volume of volatile solids in m³ after digestion, which reduces volatile solids content by 50% and decreases the moisture content to 90%. Report your answer correct to two decimal places.
