When the FOG Clears

Nicholas Drake Blog, News & Media, Precast

As today’s restaurants, hotels, hospitals, and other commercial locations cater to an ever-growing population, so do the systems that treat and transfer the wastewater these businesses generate. The demand is greater than ever for pretreatment devices that protect sewer lines and prevent blockages and sanitary overflows by removing fat, oil, grease, and grit (FOG). Those involved in the effort to maintain our sewer systems must look to robust devices that can stand up to the task. Precast concrete interceptors, separators, and their related appurtenances offer the best choice for engineers, contractors, and communities seeking FOG solutions.

Designing Pump Stations to be Wipes Ready (WEF eShowcase)

Brent Petring Blog, Jensen Water Resource Blog, Pump Stations

Our division manager recently had the opportunity to present an eShowcase webcast for the Water Environment Federation (WEF). The discussion focused on the effect that nondispersible wipes have on submersible sewage pump stations and what steps designers can take to overcome these challenges. The specific challenges that wipes present for pump stations include: Effects on submersible pumps (ragging, shaft deflection) Effects on level detection (electrical shorts, float failure) Collection of debris & Fats/Oils/Grease (FOG) layer Each challenge has its own unique solution, or combination of solutions. By understanding the challenges that each unique pump station application presents and pairing the appropriate solution, designers can …
