Q9

Thickening in sludge management is removal of ________.

  • A) Water
  • B) Non-organic matter
  • C) Organic matter
  • D) Pathogenic organisms
AI Explanation
Sludge thickening primarily removes water from sludge to increase its solids concentration. It reduces sludge volume before subsequent treatment processes such as digestion or dewatering.

…………..involves heating of the sludge to 70 0C for 30 minutes.

  • A) Maturation ponds
  • B) Sterilization
  • C) Pasteurisation
  • D) Chlorination
AI Explanation
Pasteurisation involves heating sludge to a specified temperature for a set period to reduce pathogenic organisms. A common sludge pasteurisation condition is about 70 °C for 30 minutes.

Q11

Stages of sludge processing involve?

  • A) All
  • B) Digestion and dewatering
  • C) Final disposal
  • D) Thickening
AI Explanation
Sludge processing includes several stages such as thickening, digestion, dewatering, and final disposal. These stages collectively reduce sludge volume, stabilize organic matter, and prepare it for safe disposal or beneficial use.

Q12

Which of the following sludge management stage accomplished through the removal of the biodegradable organic matter of the sludge?

  • A) Conditioning
  • B) Dewatering
  • C) Thickening
  • D) Stabilization
AI Explanation
Sludge stabilization is the stage designed to remove or biologically degrade biodegradable organic matter. This reduces putrescibility, odours, and potential health risks associated with untreated sludge.

Q13

For sludge stabilization, chemical stabilization is accompanied by ……. of an organic matter. ororganic matter?

  • A) Reduction
  • B) Oxidation
  • C) Bacteria
  • D) Both B& C
AI Explanation
Chemical stabilization involves chemical reactions that help reduce the biodegradable nature of organic matter in sludge. Oxidation is a key mechanism by which organic matter can be stabilized.

Q14

A process in sludge management for preparation for dewatering is known as_________.

  • A) Conditioning
  • B) Disinfection
  • C) Dewatering
  • D) Stabilization
AI Explanation
Sludge conditioning is performed before dewatering to improve the release of water from sludge. It commonly uses chemicals or other treatments to enhance the efficiency of dewatering.

Q15

---------is the principle component to inactivate the pathogenic microorganisms in the composting.

  • A) Ozonisation
  • B) Pressure
  • C) Tempersture(55-650C)
  • D) UV radiation
AI Explanation
Temperature is the principal factor responsible for inactivating pathogenic microorganisms during composting. Maintaining temperatures around 55–65 °C for an adequate period promotes pathogen destruction.

Q16

A sludge with a solids load of 120 kgSS/d and a solids concentration of 2.0 % (20,000 mg/L) will have a flow of?

  • A) 4.0 m3/d
  • B) 6.0 m3/d
  • C) 5.0 m3/d
  • D) 7.0 m3/d
AI Explanation
A 2.0% solids concentration is approximately 20 kg solids per m³ of sludge. With a solids load of 120 kg/d, the flow is 120 ÷ 20 = 6.0 m³/d, so the correct option is actually B.

Q17

Which of the following sludge management stage include preparation for dewatering?

  • A) Stabilization
  • B) Thickening
  • C) Dewatering
  • D) Conditioning
AI Explanation
Sludge conditioning is the preparation step performed before dewatering. It alters sludge properties, often through chemical or physical treatment, to improve water release during dewatering.

Q18

---------- metallic coagulants is/are used in conditioning of sludge.

  • A) Aluminium sulphate
  • B) Ferrous chloride
  • C) Ferric chloride
  • D) Both A& B
AI Explanation
Metallic coagulants such as aluminium sulphate and ferrous chloride can be used in sludge conditioning. They promote floc formation and improve the separation of water from solids.

Q19

..........is the main natural water removal mechanism/s in the sludge dewatering.

  • A) Digestion
  • B) Percolation
  • C) Landfill
  • D) Incineration
AI Explanation
Percolation is a natural mechanism for removing water from sludge during dewatering, particularly in systems such as drying beds. Water moves through the sludge and drainage layer under gravity.

Q20

Disposal of sludge in the mining areas is known as--------.

  • A) Ocean disposal
  • B) Sanitary Landfill
  • C) Maturation ponds
  • D) Land reclamation
AI Explanation
Disposal or placement of sludge in mining areas can be used to restore and improve disturbed land. This practice is known as land reclamation.

Q21

Removal of organic matter in sludge management is known as-------.

  • A) Dewatering
  • B) Disinfection
  • C) Volume reduction
  • D) Mass reduction
AI Explanation
Removal or destruction of organic matter reduces the mass of solids in sludge. This is therefore considered a mass reduction process rather than dewatering, which primarily removes water.

Density of sludge in processing stages is close to?

  • A) 100kg/m3
  • B) 1000kg/m3
  • C) 10kg/m3
  • D) 500kg/m3
AI Explanation
The density of sludge is generally close to that of water, which is approximately 1000 kg/m³. The exact density varies with solids concentration and composition.
