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 […]
INTRODUCTION Grit removal efficiency is often the silent variable that dictates the lifespan of downstream biosolids equipment, clarifier drives, and digesters. While the civil design of grit chambers (vortex vs. detritor vs. aerated) garners significant attention during the design phase, the mechanism for extracting that captured grit—the grit pump—is the common failure point. Engineers often […]
1. Introduction In the complex hierarchy of municipal and industrial water and wastewater infrastructure, piping accessories—couplings, expansion joints, repair clamps, tapping sleeves, and restraint mechanisms—often receive less scrutiny than high-capital assets like pumps or membrane bioreactors. However, these components constitute the critical connective tissue of the entire conveyance system. They are the primary defense against […]
1. Introduction In municipal and industrial wastewater treatment, the management of residual solids—commonly referred to as sludge handling—represents one of the most complex and cost-intensive portions of the plant lifecycle. While the liquid treatment train often garners the primary focus regarding effluent compliance, the solids handling train dictates operational efficiency, disposal costs, and often the […]
Strategies for Volatile Solids Reduction in Wastewater Treatment Understanding Volatile Solids in Wastewater Volatile solids (VS) are a critical component of wastewater, representing the organic matter that can be decomposed by microorganisms. They play a significant role in the efficiency and effectiveness of treatment processes. Effective volatile solids reduction is essential for optimizing resource recovery […]
Introduction Aeration systems consume approximately 50% to 70% of the total energy usage in a typical biological wastewater treatment plant. For consulting engineers and plant directors, the selection of aeration equipment is not merely a component choice; it is the single largest determinant of the facility’s 20-year lifecycle cost profile. A common friction point in […]
INTRODUCTION For municipal and industrial wastewater treatment plants, aeration typically accounts for 50% to 70% of total plant energy consumption. Consequently, the selection of air generation technology is arguably the single most critical decision influencing a facility’s 20-year operational expenditure (OPEX). Engineers tasked with upgrades or new plant designs frequently encounter a choice between market […]
Top Water and Wastewater Conferences 2024: Industry Insights and Networking Key Themes Shaping the 2024 Water and Wastewater Conferences The focus on emerging technologies in water treatment is paramount for the 2024 water and wastewater conferences. These technologies, including advanced filtration systems and real-time monitoring solutions, are best suited for municipalities aiming to enhance operational […]
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. […]
