- Vacuum Systems: Use negative pressure to move waste, ideal for specialized applications like airports and marinas.
Treatment Facilities
- Primary Treatment: Removes large solids and sediments from wastewater.
- Secondary Treatment: Uses biological processes to break down organic matter.
- Tertiary Treatment: Provides advanced filtration and disinfection for high-quality effluent.
Innovative Technologies
- Bioreactors: Employ microorganisms to treat wastewater efficiently.
- Membrane Filtration: Utilizes semi-permeable membranes to remove fine particles and contaminants.
- Aerobic and Anaerobic Digestion: Breaks down organic waste, producing biogas as a renewable energy source.
