Introduction For municipal and industrial engineers, few instruments cause as much operational frustration as the humble pH/ORP analyzer. Despite being fundamental to process control—dictating coagulation efficiency, biological health, and disinfection compliance—these electrochemical sensors are notorious for drift, fouling, and frequent replacement requirements. In many wastewater treatment plants (WWTPs), it is not uncommon to find up […]
Introduction For municipal and industrial engineers, the failure of a water control gate is rarely a minor operational annoyance; it is a critical vulnerability that can lead to catastrophic flooding, regulatory non-compliance, and significant safety hazards. While pumps often receive the lion’s share of attention in hydraulic modeling, the static and dynamic isolation provided by […]
INTRODUCTION In municipal water and wastewater treatment, the failure of a chemical feed system is rarely a minor inconvenience; it is often a reportable event. According to industry reliability studies, chemical dosing failures account for a significant percentage of process upsets, leading to disinfection by-product (DBP) violations, coagulation failures, or pH excursions. For the design […]
FACILITY BASIC INFORMATION Official Name: Steven M. Clouse Water Recycling Center (Formerly Dos Rios Water Recycling Center) Location: 3495 Valley Road, San Antonio, Bexar County, Texas 78221 Operating Authority: San Antonio Water System (SAWS) Design Capacity: 125 MGD (Average Daily Flow) Current Average Flow: ~75–85 MGD Population Served: Approx. 1.2 million (Greater San Antonio Metro) […]
1. Introduction Automation in the municipal water and wastewater sector serves as the central nervous system of critical infrastructure. Unlike discrete manufacturing, where systems function in controlled environments with predictable cycles, water and wastewater automation must contend with geographically dispersed assets, variable biological loading, hydraulic non-linearities, and harsh operating conditions. For consulting engineers, plant managers, […]
Sodium Hypochlorite Disinfection: Chemistry and Application in Water Treatment Chemical Properties of Sodium Hypochlorite When it comes to disinfecting water, sodium hypochlorite is like that overachieving student in class — always raising its hand to answer questions and impress everyone with its capabilities. But what exactly makes this compound so effective? Let’s break down the […]
