Introduction In the design of water and wastewater treatment facilities, the rapid and uniform dispersion of chemicals—coagulants, disinfectants, and neutralizing agents—is a fundamental determinant of process efficiency. A surprising statistic in the municipal sector indicates that up to 30% of chemical costs are wasted due to inefficient mixing, leading to overdosing to achieve regulatory compliance. […]

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 One of the most persistent challenges in water and wastewater engineering is the interface between disparate systems. Whether connecting a new ductile iron pipeline to an existing asbestos-cement main, retrofitting a modern submersible pump onto a 30-year-old discharge elbow, or automating manual valves with electric actuators, the success of the project often hinges on […]
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 […]
Introduction Aeration systems represent the single largest energy consumer in biological wastewater treatment, typically accounting for 50% to 75% of a facility’s total electrical demand. For decades, the industry relied on robust but inefficient positive displacement (PD) lobe blowers or uncontrolled multistage centrifugal systems. However, the modern regulatory environment, characterized by strict nutrient limits and […]
