- 1. Physical MediaSand and Gravel Filters: Simple yet effective for removing larger particles, commonly used by Sewage Treatment Companies to ensure initial water quality improvement.
Activated Carbon: Highly porous, it adsorbs organic compounds and certain heavy metals, making it a favored media in many Sewage Treatment Company processes.
Media Filtration: Uses specialized grains like anthracite or zeolite for advanced particle removal, enhancing the overall efficacy of Sewage Treatment Company operations.
- 2. Biological AgentsActivated Sludge: A suspension of microorganisms that consume organic pollutants, essential in the biological treatment processes employed by Sewage Treatment Companies.
Biofilms: Colonies of bacteria attached to surfaces, commonly used in fixed-film reactors, providing a robust biological treatment layer in Sewage Treatment Company setups.
Algae-Based Systems: Utilize algae's ability to consume nutrients and produce biomass for energy, representing innovative approaches adopted by forward-thinking Sewage Treatment Companies.
- 3. Chemical AdditivesCoagulants and Flocculants: Enhance particle settling by aggregating smaller particles into larger, denser flocs, critical steps in the treatment workflows of Sewage Treatment Companies.
pH Adjusters: Maintain optimal pH levels for biological processes, ensuring that Sewage Treatment Company treatments remain effective and efficient.
Oxidants: Such as hydrogen peroxide or ozone, used for advanced oxidation processes to degrade refractory organics, offered by Sewage Treatment Companies as part of their advanced treatment services.
- 4. MembranesMicrofiltration (MF): Removes particles larger than 0.1µm, playing a crucial role in the membrane-based treatments implemented by Sewage Treatment Companies.
Ultrafiltration (UF): Targets particles and macromolecules larger than 0.01µm, commonly deployed in Sewage Treatment Company setups for enhanced filtration.
Nanofiltration (NF): Removes small molecules, ions, and dissolved organics, adding another layer of purification in Sewage Treatment Company processes.
Reverse Osmosis (RO): Provides the highest level of purification, suitable for producing potable water, often utilized by Sewage Treatment Companies for reuse applications.
