  • How Seismic Use Group Classification affects your Water Storage Tank

    When purchasing a bolted steel tank or a welded steel water storage tank, one of the key criteria determining the design parameters of the tank is the Seismic Use Group (SUG) classification. The term Seismic Use Group is essentially the same as the terms Occupancy Category and Risk Category used by the International Building Code (IBC) and the ...

  • Tetrapak, Alfa Laval, Westfalia, Cream separators and Sialex®Ring - Case Study

    Tipperary Co-operative, use Sialex®Ring to help control "Scaling" on Plate Heat and Shell and Tube heat exchangers on their " hot water circuits". A further area suitable to benefit from Sialex® is in the Cream separators. These devices are prone to "Scale" build up on flushing jets. Cleaning requires did-assembly and cleaning. This can occur several times during a year. Platetek ...

  • Atomic Layer Etching – Changing the Art of the Possible

    The society of vacuum coaters (SVC) deserves to be better known. It was founded in 1957 during a surge in the use of vacuum coating techniques such as sputtering and evaporation. The techniques go back a very long way: that man Edison filed a patent for coating phonograph cylinders in 1892 (It will never catch on). Did you know that the shiny surface inside your crisp packet is a vacuum ...

  • Reverse Osmosis and Nanofiltration Membrane Filtration Systems: Common Problems and How to Fix Them

    Reverse osmosis (RO) and nanofiltration (NF) are membrane filtration technologies that are designed to remove solute ions and molecules from a pretreated liquid stream. Well-designed RO/NF units are compact and demand relatively little maintenance, making them an attractive alternative to conventional treatment trains. Even despite the merits of today’s efficient RO/NF technologies, it pays ...

  • Oil Recycling - Case Study

    The problem: Waste oil recycling contributes very much to climate protection through (CO2) energy saving. Compared to the production of base oil the re-refining of waste oil uses 34 % less resources. In the sixties the German government was subsidising the re-refining of waste oil. Because of that the use of waste oil as a fuel was neglected. The used oil re-refining is the ...

  • Kansas Facility Finds Fast, Reliable Fix to Cavitation Damage

    The Hutchinson (Kansas) Water Plant gets its water from 20 wells. The water is pumped out of the wells and into a reverse osmosis water treatment center to purify and ensure safe drinking water. At that point, a portion of the water is taken off from the main line, run through the reverse osmosis system and then mixed back ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...
