  • Sewer Level Monitoring System - a case study

    Background - The business of sewage level monitoring in sewers is accelerating across many countries. Strict regulations, the need to avoid environmental disasters, violation fines, early warnings and planning needs are just some of the forces shaping this growing trend.   Challenges Quantifying sewage flow and level is one of the most ...

  • Development and Implementation of an Alternative Emissions Monitoring Program for Carbon Monoxide Compliance for Fluidized Catalytic Cracking Unit CO Boilers

    This paper presents the results of an alternative emissions monitoring test program for the Fluidized Catalytic Cracking Unit (FCCU) CO boilers at major oil refinery. Alternative emissions monitoring systems can be used in lieu of other compliance monitoring techniques (e.g., periodic emissions testing, continuous emissions monitoring) to relate monitored operating conditions which might indicate ...

  • Case study - UV systems for spas & hydro pools

    With the rise of health centres and leisure clubs throughout the UK, a key feature in many modern facilities is the inclusion of spas and hydro pools.  As a specialist aquatic application, spas and hydro pools feature high turnover rates, high bather loads, increased turbulence and water temperatures above 35oC.  This combination of factors provides a perfect breeding ground for harmful ...

  • miniSODAR

    The miniSODAR is a high-frequency Doppler sodar system that was designed to measure the atmospheric wind profile from 15 meters to 150/200 meters (data is often available to 250 meters) in 5-meter increments. It operates by generating a short tone burst (30 ms to 100 ms) in the frequency range of 4 kHz to 6 kHz. It monitors the low-level acoustic signal echoed by the atmosphere. The echo is ...

  • Fine particle capture in biomass boilers with recirculating gas cyclones: Theory and practice

    This paper addresses the theoretical development and experimental validation of optimized recirculating reverse-flow gas cyclones. The simulation of these systems is based on the predictive properties of a finite diffusivity model, modified to include partial recirculation of the cyclones' emissions. Experimental validation was obtained at laboratory and pilot scales at low temperatures (up to ...

  • Sierra helps Biotech firm build their Competitive edge - Case Study

    Challenged by their outdated gas mixing systems, budgetary constraints and a turbulent economy, a leading US biotech firm, who depends on precision gas mixing and blending to maintain synthetic air environments for research, sought out Sierra to help streamline and improve their processes and cut costs. Sierra engineers identified current system weak points and recommended the new  ...

  • Mono on the move with sintec

    Mono’s Widethroat W range pump forms an essential part of Sintec’s mobile system by pumping the thicker groutmixes more quickly and efficiently. Once the mobile system is in-situ and drilling of an exploratory hole is almost complete, a mixer combines the bentonite/cement grouts to form bentonite slurry. This is then transferred by the W Range pump to the holdingtank ready for injection into the ...

  • Information use in Nepal`s national adaptation programme of action

    Nepal is passing through a turbulent period of transition, reorganizing its internal political boundaries, establishing a federal structure, and changing the very nature of the national government. Since 2008, Nepal’s priorities have been dominated by these political imperatives, a post-conflict peace process, and attempts to integrate Maoist ex-insurgents into the national mainstream. This ...

  • Gill Instruments case study featured in AWE International

    AWE International magazine, which is focused on the environmental analysis industry, recently featured Gill Instruments in a case study about environmental monitoring with solid-state meteorological instruments. The case study includes information about all of the products within the Gill Instruments range, with information about their advantages within the environmental analysis field. We have ...

  • CU-Boulder leading study of wind turbine wakes

    While wind turbines primarily are a source of renewable energy, they also produce wakes of invisible ripples that can affect the atmosphere and influence wind turbines downstream -- an issue being researched in a newly launched study led by the University of Colorado Boulder's Julie Lundquist, assistant professor in the atmospheric and oceanic sciences department. The study, called the Turbine ...


  • Amassing Wind Information

    Wind is a variable resource, but not an indecipherable one. Second Wind encourages harnessing the full range of wind sensing technologies that are available today. When it comes to wind information, much attention is focused on the choice of wind measurement technology and data collection practices in wind resource assessment and project design. Right now, wind data plays a limited role in the ...


  • Replacement Fill Control Valves with Electronic Flow and Metering Improve Pressure, Stop Leakage and Prevent Valve Failures

    The City of Modesto, California is situated 90 miles east of San Francisco and has approximately 200,000 residents relying on 200,000 of gallons of water a day. The City needed to upgrade three water storage tanks that hold approximately 750,000 gallons each. After years of using motor operated valves to fill water storage tanks, the city recognized that there were just too many problems. ...

  • Skimming Oily Wastewater

    As large generators of oily wastewater tighten effluent controls, the U.S. Environmental Protection Agency (EPA) is targeting smaller generators. Some of the firms receiving their attention are smaller manufacturing plants, automotive garages, mobile equipment service shops and truck farms. Many of these firms do not have access to a sanitary sewer system that will accept oily wastewater. Because ...

  • UV disinfection for enhanced oil recovery and other oilfield applications

    One of the biggest challenges facing oil companies today is how to extract more oil from the discoveries made in the last 40 years. Estimates vary, but approximately 66% of the discovered oil gets left in the ground. The International Energy Agency has estimated that if, in the next 20 years, this figure could be reduced to 50%, then this would increase the world's recoverable oil by 1.2 trillion ...

  • RO Feedwater: Treat It Right

    Summary Crossflow membrane filtration systems, such as reverse osmosis (RO), nanofiltration (NF) or ultrafiltration (UF), are good alternatives to traditional filtration and chemical treatment. However, to get the best performance from them, careful attention must be paid to feedwater conditions. Pretreating feedwater can lengthen the life of membrane elements, improve the quality of the ...

  • Air Pollution Control in the Printing and Web Coating Industries

    For many U.S. companies in the printing and web coating business, the use of an Air Pollution Control System (APCS) to control harmful air pollutants is not new.  In these industries, depending upon their location, companies have been installing APCS since the early 1970's.  However, for some companies the clock is still ticking regarding their compliance with local, state and federal ...
