Introduction to Water Treatment Instrumentation & Controls: SCADA Sensors & Automation One of the most frequent and costly failures in modern water infrastructure is not structural or mechanical—it is a failure of visibility. When an aeration blower consumes 40% more energy than required because a dissolved oxygen sensor has drifted, or when a remote lift […]

Introduction In municipal and industrial water treatment, few parameters are as universally critical—or as frequently misunderstood—as pH. The precise control of hydrogen-ion activity governs the efficacy of coagulation and flocculation, regulates the toxicity of ammonia and heavy metals, prevents corrosive degradation of infrastructure, and dictates the metabolic health of biological nutrient removal (BNR) processes. Understanding […]

INTRODUCTION In municipal and industrial water and wastewater facilities, a failing analytical sensor does not just drop a signal—it cascades into process upsets that can cost tens of thousands of dollars in chemical overdosing, cause severe corrosion, or trigger immediate regulatory compliance violations. Relying on blind assumptions rather than real-time data is no longer viable […]

Introduction to Multi-Stage Water Filtration Systems: 2-Stage to 7-Stage Compared One of the most frequent and costly specification errors in industrial and municipal water treatment is the misalignment of multi-stage filtration trains with the specific influent water profile. Over-engineering a system with redundant stages unnecessarily inflates capital expenditure (CAPEX) and creates parasitic pressure losses. Conversely, […]

Introduction Membrane separation technologies have become the backbone of modern municipal desalination, industrial process water generation, and advanced wastewater reuse. However, misjudging feed water chemistry or specifying the wrong membrane configuration can lead to catastrophic fouling, severe hydraulic imbalances, and operational expenses (OPEX) that rapidly eclipse capital cost savings. To navigate RO Systems & Buying […]

INTRODUCTION One of the most frequent critical specification mistakes in modern water and wastewater engineering is treating a membrane module as a commoditized “black box.” An engineer might specify an ultrafiltration (UF) system based solely on pore size and nominal flux, only to experience catastrophic fiber breakage during rigorous air scouring or rapid permeability decline […]

INTRODUCTION For decades, municipal and industrial water treatment facilities have relied on conventional polymeric membranes—primarily polyethersulfone (PES), polyvinylidene fluoride (PVDF), and thin-film composite (TFC) polyamides—for microfiltration, ultrafiltration, and reverse osmosis. While these conventional materials revolutionized the industry, they are fundamentally constrained by the permeability-selectivity tradeoff (often referred to as the Robeson upper bound), high susceptibility […]

INTRODUCTION Applying standard municipal biological treatment parameters to a petrochemical effluent stream or a dairy processing plant is a fast track to biomass toxicity, frequent permit violations, and catastrophic plant downtime. The engineering discipline of Wastewater Treatment Applications: Industry-Specific Solutions exists specifically to address the radical variances in influent characteristics, hydraulic peaking factors, and regulatory […]

Introduction In municipal and industrial water treatment, inaccurate chemical dosing directly translates to regulatory permit violations, accelerated equipment corrosion, and thousands of dollars in wasted chemical expenditures annually. Specifying the correct dosing equipment requires navigating a complex matrix of fluid rheology, vapor pressure characteristics, turndown requirements, and control schemes. Welcome to the comprehensive Chemical Metering […]

INTRODUCTION The promulgation of stringent regulatory limits—including the EPA’s National Primary Drinking Water Regulation (NPDWR) setting Maximum Contaminant Levels (MCLs) for PFOA and PFOS at an unprecedented 4.0 parts per trillion (ppt)—has fundamentally shifted the landscape of municipal and industrial water treatment. For engineers, treating per- and polyfluoroalkyl substances as a monolithic contaminant class is […]
