  • Building Energy Modeling 101: HVAC Design and Operation Use Case

    A great deal of energy use in buildings goes toward heating, ventilation, and air-conditioning (HVAC). In 2015, HVAC consumed 15.5 quads. The first step in reducing HVAC energy use is reducing heating and cooling load—i.e., the amount of heat that needs to be added to or removed from a building—typically by reducing heat from equipment and lighting; minimizing unnecessary ...

  • Search Query What are you looking for? How our minidot was swept up in a flood — and survived

    The miniDOT logger is a submersible water logger that measures dissolved oxygen and water temperature. Scientists working in aquaculture are familiar with the quality of PME instruments, which range from small loggers to larger monitoring systems. But what they may not be aware of is that PME’s innovative products occasionally become ...

  • How a Specialized Automatic Control Valve Solved Flooding

    The Colombian area of Antioquia creates much of its clean power from hydropower plants along the Guadalupe River. The Guadalupe IV hydroelectric plant generates power with three vertical axis turbines that discharge water below the river level. To prevent flooding, however, the plant needed a solution that ensured the ejector ...

  • Reconciling hydrology with engineering

    Hydrology has played an important role in the birth of science. Yet practical hydrological knowledge, related to human needs for water storage, transfer and management, existed before the development of natural philosophy and science. In contemporary times, hydrology has had strong links with engineering as its development has been related to the needs of the design and management of water ...

  • Diesel Engine Rebuild Facility

    The facility rebuilds both tractor and truck diesel engines. The process uses soaps and surfactants to clean the engine and parts during the rebuilding process. The wastewater generated is treated using the Floccin 1105 in a water reuse system designed by Integrated Engineers, Inc. All of the water is reused in this closed loop system. Here is an example of the jars before and after treatment ...

  • Engine manufacturer saves $45,000

    The Problem: An engine manufacturer was faced with costly lost production in their 10,000gallon central honing oil system. The central system had been contaminated with 1500 gallons of water. The oil supplier’s lead-time for replacing the oil was just over 72 hours, and draining, cleaning, and drying the system would add to the downtime. SRS had already been conducting a successful coolant ...

  • Advanced engineering for ATEX solutions

    The process of disinfecting water with UV light is a proven technology for drinking and process water in many industries, however the high standards required by the offshore industry command these systems to be engineered way beyond the normal specification of many manufacturers. When a leading offshore contractor based in Malaysia required two high specification ATEX systems for operation in ...

  • Engine detonation with bioethanol cavitation

    Bioethanol is an alcohol of an organic origin which receives from a sugar ferment reaction. In the process of ethanol formation, starch from grains of plants turns in simple sugar in reaction with enzymes. Natural sugar ferments with yeast and form a mix of alcohol, water and unfermented remains. Alcohol is separated from a mix in distillation capacities and additionally clears in rectifying ...

  • Wastewater engineers go with the flow

    The efficiency of maintenance work has been improved by water treatment engineers employing Intellisonde monitors in their final effluent. Designed primarily to measure water quality, the Intellisondes also measure flow, and this reading is being used to detect the accumulation of debris that necessitates a maintenance visit. Wastewater treatment efficiency is often measured by the analysis of ...

  • Flexible engineering designs for urban water management in Lusaka, Zambia

    Urban water systems are often designed using deterministic single values as design parameters. Subsequently the different design alternatives are compared using a discounted cash flow analysis that assumes that all parameters remain as-predicted for the entire project period. In reality the future is unknown and at best a possible range of values for design parameters can be estimated. A Monte ...

  • Equivalence of Air and Water Permeability Tests in Evaluating Engineering Fabrics

    Permeability characteristics of civil engineering filter fabrics are currently evaluated by three types of tests: air permeability and falling-head and constant-head water permeability. Test procedures for the falling-head and constant-head water permeability tests are discussed, and results from these tests are correlated to air permeability results for filter fabrics. Several commercially ...

  • Effect of water addition on the exergy balances of an LPG fuelled spark ignition engine

    In this paper, we investigate the effect of water addition on the exergy balance of a conventional engine. The present work is an analytical study depending on experimental measurements. A four-cylinder, LPG fuelled SI engine is used in this work, and water injection through intake manifold is used for water addition. The cylinder pressure versus crank angle, and water, air and fuel flow rates ...

  • FORUM: Balancing basics and applications in teaching environmental and water resources engineering

    This short forum suggest that engineering practitioners, asked about what they expect out of a fresh engineer immediately after their graduation in terms of on-job skills and technical training, prefer that an engineer be able to hit the road and run without too much on-job training. It suggests that engineering undergraduate curricula need to have a good balance in offering both basics and ...

  • Adsorption of crude and engine oils from water using raw rice husk

    The raw rice husk (RRH) was used as a low cost adsorbent to remove three oil compounds with different viscosities (crude oil, engine oil and spent engine oil) from an aqueous environment. Some of the sorbent specifications were characterized using a CHNSO analyzer, Fourier transform infrared, scanning electron microscope and inductively coupled plasma spectroscopy. With decreasing RRH particles ...
