WASTEWATER FILTRATION WHITE PAPERS AND CASE STUDIES

New Membrane Technology Handles High Solids, Aids Water Reuse

As global conditions place more stress on water resources, a great deal of attention is being paid to water reuse technologies, particularly those that facilitate the reuse of the next level of difficult-to-treat or highly variable raw water sources.

Pilot Studies In North Carolina With Hydrex™ Odor Solutions

Two municipalities were faced with odor issues and required corrosion prevention in their collection systems. Monitoring in the sewer lines indicated peak H2S atmospheric concentrations of 300-500 ppm. Both clients desired H2S < 20 mg/L to prevent corrosion and preferably lower to prevent H2S odor.

ABOUT WASTEWATER FILTRATION

Wastewater filtration is often part of the tertiary treatment process that involves the final removal of suspended particles from water that has passed through both the primary and secondary treatment phases and immediately precedes disinfection. As the water passes through the filter, residual suspended material and bacteria is trapped in the filter and are removed from the filtered water. Passage can be blocked by physical obstruction, biological action, adsorption, absorption or a combination of ways. Wastewater filtration is usually the final step in the solids removal process.

With regulations increasing around wastewater effluent, the use of ultrafiltration and microfiltration systems in further polishing effluent has grown. Sand or activated carbon filters can provide a media for bacterial decomposition of nutrients, converting nitrates into nitrogen gas. The rise of water reuse applications is also fueling the increasing use of filters during the final polishing stages of the wastewater treatment process.
