Introduction to Submersible Pump Metallurgy One of the most persistent and costly challenges in modern wastewater management is the premature degradation of submersible pumping equipment due to shifting influent chemistry. As water conservation efforts reduce flow rates, wastewater becomes more concentrated. Simultaneously, longer retention times in force mains and collection basins accelerate septicization, leading to […]
Introduction The modern wastewater stream has undergone a radical transformation in the last two decades. The proliferation of non-dispersible synthetic fabrics—commonly known as “flushable” wipes—combined with water conservation mandates that reduce transport velocities, has created a perfect storm for municipal and industrial operators. For engineers involved in lift station design and treatment plant operations, the […]
Biosolids Management: Best Practices for Treatment Plants Biosolids management is where regulatory pressure, operational cost, and community risk collide—get the decisions right and you control disposal costs and recover resources; get them wrong and you face fines, complaints, and rising hauling bills. This practical guide gives treatment plant operators and engineers a technical roadmap for […]
