Simul-Wash™ is a proven sustained, simultaneous air/water filter backwash system that extends the life of filter media, minimizes backwash waste, prevents mudballs from forming and frees nearly all captured filter debris – better than any other backwash method available. Simul-Wash™ works well in a variety of configurations, from horizontal and vertical pressure filters to low profile retrofit applications on gravity filters.
Tonka Water’s Simul-Wash™ backwash system is the only sustained air and water backwashing process using the “collapse-pulse” technique first documented by Amirtharajah in a landmark AWWA Research Foundation. Simul-Wash™ also meets Ten States Standards and has a low profile baffled trough design providing long and clear spans. Stainless steel is the standard construction for components uniquely suited for “vertically challenged” filters.
Simul-Wash™ is applicable with manganese greensand or any mono, dual or tri-media application. The key features of Simul-Wash™ are that it prevents media loss while using as little as half the water of a conventional backwash system. This allows the use of significantly downsized backwash system requirements. Construction costs and wash water consumption are also reduced, saving a substantial amount of money and water with every backwash.
