Introduction to Tertiary Filtration Selection For municipal and industrial engineers, the tertiary filtration stage is frequently the final safeguard between regulatory compliance and permit violations. As National Pollutant Discharge Elimination System (NPDES) permits tighten—particularly regarding total phosphorus (TP) limits of < 0.1 mg/L and strict turbidity requirements for Title 22 water reuse—the margin for error […]

INTRODUCTION One of the most persistent debates in municipal water treatment and tertiary wastewater polishing centers on the choice between proprietary membrane technologies and versatile packaged filtration systems. Engineers are frequently caught between the absolute barrier protection of ultrafiltration (UF) and the robust, forgiving nature of adsorption clarifiers or conventional multimedia filtration. This decision affects […]

Leading Water Treatment Equipment Manufacturers and Their Innovations Overview of Key Players in Water Treatment Equipment Manufacturing The landscape of water treatment equipment manufacturers is dominated by a few key players that command significant market share due to their established technologies and broad product lines. Companies like Xylem, Veolia, and SUEZ are recognized for their […]

1. Introduction The oxidation ditch is a modified activated sludge biological treatment process that utilizes long solids retention times (SRTs) to remove biodegradable organics. Oxidation ditches are typically complete mix systems, but they can be modified to approach plug flow conditions. Ideally suited for small- to medium-sized municipal wastewater treatment plants, these systems are renowned […]

Introduction In the complex ecosystem of municipal and industrial treatment facilities, the “Big Three”—pumps, pipes, and valves—often dominate the initial design conversation. However, the operational success of a plant frequently hinges on the specialized auxiliary equipment that supports the primary treatment train. When engineers search for the Top 10 Other – Other Manufacturers for Water […]

Introduction In the municipal and industrial water sector, data integrity is the bedrock of process control. Yet, a surprisingly high percentage of plant alarms—estimated by some automation audits to be over 40%—are nuisance alarms caused not by process failures, but by instrumentation drift, fouling, or improper specification. For the design engineer or plant superintendent, the […]

Introduction The movement of dewatered biosolids, screenings, and grit is often the final bottleneck in modern treatment facilities. While headworks and biological processes receive significant engineering attention, the conveyance of “cake” solids remains a frequent source of operational headaches, from housekeeping nightmares to complete mechanical failures. Engineers tasked with facility upgrades often face a critical […]

1. Introduction to Thickening Equipment in Water and Wastewater Treatment In the hierarchy of unit processes within municipal and industrial wastewater treatment facilities, sludge thickening represents a critical intermediate step between liquid treatment and solids handling. While often overshadowed by the biological treatment processes upstream or the final dewatering and disposal downstream, thickening is the […]

Selecting the Right Wastewater Management System for Your Municipality Assessing Current and Future Wastewater Needs Municipalities must accurately assess both current and future wastewater needs to select an effective wastewater management system. This assessment is best for municipalities experiencing rapid growth or those with fluctuating industrial activities. Evaluating Population Growth Projections Population growth projections are […]
