Industrial Wastewater Pretreatment Application in Portland, Oregon
Versatile Industrial Filtration Uses
Bead filters are a very versatile tool for the industrial sector with applications such as pretreatment of water supplies, integration into the production cycle, wastewater treatment, runoff treatment, cooling towers, and water recycling. Applications can be as diverse as algal harvesting to mineral recovery associated with mining operations.
Use of the units as a roughing filter takes advantage of the units’ robust resistance to biofouling. A typical HPPG or Propeller Bead® application is used as a solids removal device to reduce high suspended total suspended solids levels (300-1000 mg/L) down to a level that can be discharged into a domestic sewage system without penalty. Simple solids removal can show dramatic improvement in BOD as well as TSS levels whenever the solids are principally organic. The RCPG application is more appropriate whenever dissolved organics (soluble BOD) removal is required. The recycling capability permits oxygen transfer to be increased while extending the contact time with the biofilms. Typical roughing applications include mixed industrial wastes, food processing wastes, sludge lagoons overflows, wash down waters, and landfill leachates treatment.
Consolidate Treatment Processes
In many low flow applications, a bead filter can be used as a single step treatment in preparation for reuse or discharge. Process water for example that is contaminated with fine solids can be polished for reuse, and wash down waters that may contain a wide variety of contaminants can be concurrently treated to achieve a water low in both organics and particulates. Other applications with higher flows or dissolved compounds that are not impacted by biological decay utilize the bead filter as a tool in a treatment train to attack specific contaminants. For example, an industry with a wastewater treatment plant that must now meet more stringent effluent standards that include ammonia can use an RCPG to specifically attack this parameter (See Nitrification).
