WASTEWATER FILTRATION WHITE PAPERS AND CASE STUDIES

Activating The Sludge In Small Municipal Facultative Waste Lagoon Systems

Wastewater treatment lagoons were originally facultative in design — shallow, single and multi-cell lagoon systems that counted on wind, sunlight, anaerobic bacteria, and time for the digestion of the organic components of the wastewater.

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.
