Introduction In the transition from traditional cast iron sluice gates to modern fabricated stainless steel and aluminum slide gates, municipal engineers often find themselves evaluating two dominant North American manufacturers. The analysis of Golden Harvest vs Whipps – C for Gates: Pros/Cons & Best-Fit Applications is a critical exercise for any design engineer or utility […]
Introduction In municipal and industrial water treatment, flow measurement is arguably the single most critical variable for process control, yet it remains a primary source of operational inefficiency. It is estimated that flow measurement errors contribute significantly to the 20-30% of Non-Revenue Water (NRW) losses seen in many aging distribution systems. Furthermore, in wastewater treatment, […]
Introduction One of the most persistent debates in municipal water and wastewater treatment plant design centers on the selection of isolation and flow control gates. For decades, engineers have grappled with the choice between traditional heavy-duty cast iron sluice gates and modern fabricated stainless steel slide gates. This decision often crystallizes into a comparison of […]
INTRODUCTION In the realm of anaerobic digestion and cogeneration, the protection of downstream assets—whether internal combustion engines (ICE), boilers, or renewable natural gas (RNG) membranes—is paramount. Engineers often face a critical disconnect: the anaerobic digester produces valuable fuel, but that fuel is laden with hydrogen sulfide (H2S), siloxanes, and moisture that can destroy capital equipment […]
Membrane Bioreactor Technology: Advanced Treatment for Modern Facilities Fundamental Principles of Membrane Bioreactor Technology Membrane bioreactor technology (MBR) excels in integrated wastewater treatment, particularly for facilities aiming to enhance effluent quality while managing space constraints. It fits best when high-quality effluent is necessary for water reuse or when dealing with complex industrial wastewater that requires […]
Introduction One of the most persistent challenges in water and wastewater treatment design is the “black box” mentality regarding filtration. Engineers often focus heavily on media selection—anthracite size, sand uniformity coefficients, or GAC iodine numbers—while underestimating the critical mechanical and hydraulic interfaces that support that media. However, industry data suggests that over 70% of catastrophic […]
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 Grit accumulation remains one of the most pervasive and costly “silent failures” in municipal wastewater treatment. While headworks screens provide visible capture, grit often bypasses preliminary treatment, settling in aeration basins, reducing digester capacity by up to 30%, and causing premature abrasion failure in downstream pumps. For consulting engineers and plant directors, the selection […]
Introduction One of the most persistent and costly challenges in wastewater treatment plant (WWTP) operation is the accumulation of inorganic solids in downstream processes. Industry data suggests that up to 40% of digester volume in older plants can be lost to grit accumulation, significantly reducing volatile solids reduction and gas production. For municipal consulting and […]
