Technical Note for Engineers: This article provides a specification-level overview of Solids Dewatering Equipment for municipal and industrial applications. It focuses on engineering selection criteria, operational realities, and an impartial analysis of specific Original Equipment Manufacturers (OEMs). 1. Introduction Solids dewatering represents one of the most critical unit operations in the water and wastewater treatment […]

Introduction In the complex infrastructure of municipal water and wastewater treatment, the actuation of valves is the muscle behind process control. While electric actuation has gained ground due to advances in network connectivity, pneumatic valve actuators remain a cornerstone of industry reliability, particularly in applications requiring rapid response, high duty cycles, and fail-safe operation. For […]

1. INTRODUCTION In municipal and industrial water and wastewater treatment facilities, the containment of process basins, channels, and reservoirs is a critical engineering discipline. While historically treated as secondary accessories, cover systems and associated walkways have evolved into essential components for odor control, process stability, safety compliance, and algae mitigation. The shift from heavy concrete […]

Introduction In municipal water and wastewater treatment, valve selection is rarely the most glamorous part of the design process, yet it accounts for a disproportionate amount of maintenance hours and operational frustration. A surprising industry statistic suggests that while valves represent approximately 5% of a plant’s capital cost, they can account for up to 60% […]

Introduction In the hydraulic architecture of municipal and industrial water systems, strainers function as the primary defensive barrier for critical downstream assets. While often overshadowed by dynamic components such as pumps and control valves, the strainer is the sentinel that prevents catastrophic failure caused by entrained solids, scale, biofilm, and debris. For consulting engineers, plant […]

1. Introduction In municipal and industrial wastewater treatment, the management of odors is not merely an aesthetic concern; it is a critical operational parameter that impacts regulatory compliance, community relations, facility safety, and infrastructure longevity. Odor Control Systems (OCS) represent the primary defense against the release of nuisance compounds—principally hydrogen sulfide (H2S), mercaptans, ammonia, and […]

Introduction One of the most persistent challenges in municipal water and wastewater design is the “interface gap”—the point where mechanical flow control meets electrical automation. When a critical isolation valve fails to close during a storm event, or a modulating control valve oscillates wildly, creating damaging water hammer, the root cause often lies in a […]

Introduction Ultraviolet (UV) disinfection has transitioned from an “alternative” technology to the industry standard for pathogen inactivation in municipal water and wastewater treatment. However, a critical disconnect remains in the engineering community: the assumption that UV systems are static, “plug-and-play” appliances. In reality, an improperly specified UV system can become the plant’s largest energy consumer […]

1. Introduction In the hydraulic architecture of municipal and industrial wastewater treatment plants, telescoping valves—frequently referred to as slip pipes, decant valves, or sludge draw-off valves—serve a critical, albeit mechanically straightforward, function. Unlike pressurized isolation valves used in distribution networks, telescoping valves operate primarily in open-channel or gravity-flow environments within clarifiers, sludge thickeners, settling tanks, […]
