2. Identify the environmental benefits of switching to "water free" technology, considering water conservation, reduced sludge generation, and overall environmental impact.
3. Create a simple cost-benefit analysis comparing the traditional wet system with the "water free" solution, considering the long-term costs and benefits.
4. Summarize your findings in a report that outlines the potential benefits and justifies the investment in "water free" technology.

Techniques

Chapters on "Water Free" Grit & Screenings Gates

Chapter 1: Techniques

1.1 Traditional Wet Processes

• Grit Removal:
  • Wet Screens: Coarse screens with water flow for removing larger debris.
  • Grit Chambers: Settling tanks with water flow to allow heavier grit to settle.
• Screenings Removal:
  • Screens: Bar screens or fine mesh screens to catch screenings.
  • Shredders/Grinders: Used to reduce screenings volume and aid in disposal.

1.2 "Water Free" Innovations

• Dry Grit Screening:
  • Vibratory Screens: Utilize vibration to separate grit from wastewater without water.
  • Air-Assisted Separation: Combines air flow and mechanical screening to efficiently remove grit.
• Dry Screenings Handling:
  • Compactors: Compress and dewater screenings using mechanical force.
  • Air Drying: Use forced air to remove moisture from screenings.
