  • 5 Essential tips about snowmobile safety

    Extreme conditions and fast speeds are what make riding so much fun, but they come with risks. When you ride with your family and friends, you need to be aware of potential risks.  A modern snowmobile can weigh over 600 pounds and travel up to 90 mph. Due to poor judgment, excess speed, and alcohol — approximately 200 deaths and 14,000 injuries occur every year. But this does not mean ...

  • ‘Smart’ flood alleviation system protects Portsmouth

    In late 2014, Southern Water completed a major project to reduce the risk of sewer flooding in parts of Portsmouth and Southsea. Substantial works were undertaken to divert runoff and tidal ingress, and a ‘smart’ hydrometeorological monitoring system was installed to enable prompt diversion of excess water during periods of high rainfall. Sewer level monitoring is undertaken in ...

  • How to Assess Fall Hazards

    Fall hazards are an ongoing concern in most workplaces and include both falls from heights as well as falls from the same level. Slips, trip and falls from both categories consistently rank among the top causes of both disabling injuries and deaths in all types of workplaces, from construction sites, to manufacturing operations to warehouses to offices. In fact, the only other category of ...

  • CO2 monitoring for Sustainagro - Case Study

    Challenges the customer faced According to former development manager for Sustainagro, Adrian Parker, before the lab had the G100 and could measure in real-time it used a titration method: "It took ages, several hours, just to do one." How the product helped The G100 has made the process much quicker; the lab can have several different flasks and ...

  • Wastewater Level Measurement Techniques

    Level monitoring and control is a fundamental requirement in any wastewater treatment process. You will find level instrumentation installed at even the simplest treatment plants for pump control, chemical storage tanks and process level controls or alarms. Operators have only limited or emergency control over treatment plant influent, so level controls and instrumentation play an important role ...

  • Deep soil mixing shoring system to construct a 60 MGD, 40 foot deep wastewater pumping station

    The City of San Mateo, CA operates three wastewater pumping stations on a 80' wide lot located in a residential area near San Francisco Bay. The age of the stations range from 12 to 50 years, the stations have difficulty pumping peak wet weather flows, and have structural and maintenance problems. For these reasons, a new station was proposed to replace the existing stations. The site layout is ...

  • An artificial intelligence approach for optimizing pumping in sewer systems

    This paper presents details of a fuzzy logic system developed for the control of sewer pumping stations for energy costs savings. This is part of an ongoing collaborative project between Anglian Water and the University of Sheffield. The model rules and operation are developed for one representative pumping station in order to enable the identification of potential benefits and inhibitors to ...

  • Municipal waste water treatment plant case study

    A municipal WWTP in the North of England was experiencing significant problems with accumulations of FOG in the Wetwell at the head of the treatment plant. The FOG would form a solid cap over the well several feet thick. This put considerable strain on the pumping gear, interrupted the performance of the float switches and required regular manual intervention from the staff. High costs were also ...

  • Hydraulic modeling - Bethel Park Municipal Authority - Case Study

    Treatment plant hydraulics is often overlooked as one of the most important aspects of treatment plant design, especially in plant upgrade scenarios where retrofitting new equipment or processes into the existing treatment train will create additional hydraulic restrictions.  Many existing plants already have a minimal amount of head available for passing peak flows through the system, which ...

  • Computation Fluid Dynamic Modeling of a Proposed Influent Pump Station

    Traditionally pump intake hydraulics have been investigated using scale physical hydraulic models. Computational fluid dynamics (CFD) is a rapidly improving technology that in some cases can be used as a cost or time effective alternative to traditional physical model methods for evaluation of pump intake hydraulics. This paper presents a case study on the use of CFD modeling to re-evaluate and ...

  • An Update on the Columbus Wet Weather Management Plan

    ABSTRACTUndergoing a system wide program for a metropolitan area of over 1 million people to address SSOs is a challenge. The same can be said for addressing CSOs throughout a system. Columbus is addressing both at once, creating a particularly daunting challenge. Columbus submitted one large report, the Wet Weather Management Plan (WWMP), to the Ohio EPA on July 1, ...

  • Model Testing Optimizes and Verifies Design of a 200-MGD Trench Wet Well for the Sugar Creek WWTP
