  • Chemical Engineering Magazine: Odor Issues and Solutions for Wastewater Treatment

    Today, there has been a dramatic increase in the number of industrial operations that are located within or near small towns and even large cities. When local residents constantly smell these industrial processes – particularly from wastewater treatment — unhappy neighborhoods are generally the result. In addition, many wastewater facilities can no longer produce odors without facing ...

  • Aeration and Mixing Bring Hussain Sagar Lake`s Ecosystem Back to Life

    Overview Hussain Sagar Lake in India faced an inflow of untreated waste and pollution causing decreasing DO levels and foul odors in the nearby community. An even more critical threat was eutrophication, or an excessive number of nutrients in the body of water, choking out the natural aquatic life. Given the lake is stagnate, circulation and the distribution of efficient aeration ...

  • Water Active: Borehole Management in Civil Engineering Projects

    Groundwater wells are common to many civil engineering schemes and their operational performance can play a crucial role in the successful delivery of a project, whether used for construction dewatering, alternative water supplies for facilities or any other application , the well performance must be optimized and high levels of operational efficiency and service availability achieved. A ...

  • Get More Out of Water Resources Engineering Models

    by Venu Kandiah, PhD, P.E. Senior Water Resources Engineer The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and ...

  • Get more out of Water Resources Engineering Models

    The effort required to develop water resources engineering models can be significant. But once developed, in many instances the models are only evaluated for a limited, or a single set of conditions. The results and predictions obtained from these evaluations are the ones used in design, presented in reports and conveyed to decision makers and the public. This approach might serve ...

  • Engineers without borders: sustainable engineering for developing communities

    Through integrated design strategies and a longstanding commitment to communities, students from Johns Hopkins and University of Maryland chapters of Engineers Without Borders and professionals from the Chesapeake EWB section collaborated on potable water, sanitation, and irrigation projects in developing communities worldwide. In Baan Bo Mai, Thailand, a pipeline was installed to provide the ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
