Introduction In municipal and industrial pumping systems, the selection of check valve technology is the primary defense against destructive hydraulic transients (water hammer) and reverse flow damage. Engineers are frequently faced with a divergent choice when specifying pump discharge control: specifying an active, electrically or pneumatically actuated solution (often synonymous with Rotork actuation on a […]
Aqua Aerobic Systems: Innovative Solutions for Wastewater Treatment Mechanisms of Aqua Aerobic Systems Aqua aerobic systems are best suited for municipalities and industries that require efficient and effective wastewater treatment solutions with a focus on biological processes. These systems leverage aerobic digestion to break down organic matter, making them particularly advantageous in settings where space […]
Introduction to Tanks and Covers in Water and Wastewater Systems Liquid containment and headspace management are foundational elements of municipal and industrial water and wastewater infrastructure. Tanks and covers serve not merely as passive storage vessels but as critical process components that define the hydraulic profile, chemical safety, biological stability, and environmental compliance of a […]
Introduction One of the most persistent challenges facing water and wastewater utility engineers is the management of disinfection byproducts (DBPs) and the volatility of chemical supply chains. While gas chlorine remains a staple in legacy infrastructure, the industry has seen a massive shift toward liquid sodium hypochlorite due to safety concerns and risk management planning […]
Introduction In municipal water distribution networks, the management of water age and the maintenance of residual disinfectant levels are critical regulatory and public health mandates. While standard fire hydrants have historically been utilized for flushing activities, the evolution of distribution system engineering has necessitated the development of dedicated hydrant flushers. These devices—ranging from manual blow-offs […]
Solids Management in Wastewater Treatment: Strategies and Technologies Overview of Solids Management in Wastewater Treatment Did you know that nearly 80% of the solids generated in wastewater treatment plants end up in landfills? That's a staggering amount of waste that could be managed more effectively. Solids management is not just a regulatory requirement; it's a […]
Introduction In municipal water distribution and industrial fluid handling, the “valve selection paradox” is a frequent challenge for consulting engineers: the most expensive valve upfront is often the cheapest over 20 years, yet the wrong hydraulic application can destroy even the highest-quality equipment in weeks. A surprising statistic from hydraulic efficiency studies suggests that up […]
Introduction In municipal and industrial hydraulic systems, the management of high pressure differentials presents a distinct physical challenge: cavitation. When water accelerates through a valve restriction to the point where the static pressure drops below the fluid’s vapor pressure, vapor bubbles form. As the fluid recovers pressure downstream, these bubbles collapse with violent force, generating […]
Introduction In the landscape of municipal and industrial water and wastewater treatment, the dry pit pump configuration remains a cornerstone of reliability, maintainability, and hydraulic versatility. Unlike submersible installations where the pump and motor are submerged in the process fluid, dry pit installations separate the fluid handling equipment from the wet well. The pump is […]
Introduction The sudden urgency surrounding PFAS/PFOA compliance, combined with the perennial need for taste, odor, and organics removal, has placed Granular Activated Carbon (GAC) technology at the forefront of utility capital planning. For many consulting engineers and plant directors, the challenge is no longer just selecting a media type, but specifying the mechanical vessel systems […]
