  • Replacement of Hot Caustic Paint Stripping Process with High Pressure Water Jet System: Ford Australia

    Ford Australia Ltd replaced an existing hot caustic paint stripping process, used for cleaning car skids, with a high pressure water jet system. This project has resulted in annual savings in the order of $300,000 from reduced chemical, energy and waste disposal costs. Significant improvements in paint quality were also achieved through the ability to clean the skids on a more regular basis than ...


  • The case for water jet tank cleaning

    To maintain a consistently high level of product quality, today's processing plants must ensure that their tanks and reactors are thoroughly cleaned on a regular basis. The direct expenses involved can be substantial, and adding indirect costs {e.g., downtime and compliance with safety and environmental regulations) puts extreme pressure on tight operations budgets. To meet this challenge, more ...

  • Simulation of overflow nappe impingement jets

    Rectangular jets constitute one of the energy dissipation methods in the overtopping of dams. The high turbulence and aeration phenomena that appear in falling jets and dissipation basins make it difficult to carry out studies based only on classical methodologies. There are studies modelling spillways with computational fluid dynamics which produces accurate results. However, the study of ...

  • Pressure Washing Equipment for Temperature Control

    Pressure washing equipment with heating capabilities has one advantage over non-heated pressure washing equipment. These machines can use hot as well as cold water. Therefore, when purchasing pressure washing equipment, it is always a good idea to purchase machines that allow for temperature control. Hot Water Applications Hot water cleans where cold water cannot. Heat acts on ...

  • Industrial Pressure Washer for Removing Heavy Layers of Grime and Grease

    An industrial pressure washer usually has pressure level ranging from 1000 to 3500 psi. This machine also heats water to high temperatures; a commercial pressure washer can reach temperatures as high as 330°F. This combination of heat and high pressure works to dissolve dirt and grease and wash it away from the surface. An industrial pressure washer may also use cold water when heat is not ...

  • Lanes high-powered jetter relieves village flooding risk

    Lanes for Drains engineers have saved a community near Bristol from the threat of flooding by cutting tonnes of calcite from a pipe taking spring water to the River Avon. They brought in a trailer-mounted jetting unit that can deliver water at up to 15,000 PSI Ð up to twice the pressure of a conventional HPWJ machine Ð to blast the mineral deposits. Engineers at the Lanes for Drains ...

  • Spray flash evaporator for low-temperature saline water desalination application

    A new spray-type flash evaporator is suggested for the application of saline water desalination. The flash evaporator is 1000 mm in height and 1200 mm in diameter, with a water injection arrangement inside. The evaporator design is based on experiments conducted at vacuum pressures between 10 and 18 mm of Hg, and at saline feed water temperatures between 26?C and 32?C. The saline water is ...

  • ELECTRONIC WATER TREATMENT REDUCES FOULING AND CORROSION IN PIPELINES

    Increasing pressure loss in the pipeline is often caused by scale corrosion or product fouling of the internal surfaces. This condition slows transmission and distribution capacity, and can require more than just routine maintenance if it remains unaddressed. Interior corrosion, fouling and leakage in pipeline systems will adversely impact bottom-line operations. ...

  • Electronic water treatment reduces fouling in heat exchangers

    The deposition of material on heat transfer surfaces is called fouling which significantly impacts on the thermal and mechanical performance of heat exchangers. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers as well as impeding fluid flow, accelerating corrosion and increasing pressure drop across the heat ...

  • Use of Water Based Paint To Reduce Solvent Emissions: Brisbane Motor Bodies

     Background For the last twelve months Richard Powell has been using water based 'base coat' paints in his smash repair business at Woolloongabba. These paints use water, instead of solvent, as the carrier for the basic paint constituents, and do not release any harmful vapours to the atmosphere. Richard has been in the smash repair business for more than twenty five years and ...


  • How a new source of water is helping reduce conflict in the Middle East

    Scientists and others look to desalination as a way to unite longtime enemies in a common cause. Ten miles south of Tel Aviv, I stand on a catwalk over two concrete reservoirs the size of football fields and watch water pour into them from a massive pipe emerging from the sand. The pipe is so large I could walk through it standing upright, were it not full of Mediterranean seawater pumped ...

  • Dredging Technology – Underwater Excavation and Construction

    The presence of water is ussualy considered a nuisance in construction, particularly when excavating removing water is common practice. In some cases however, water can be a very useful tool that may simplify things greatly. With the “flooded excavation principle”, the construction site is flooded after the retaining walls have been installed (e.g. sheet pile). When the ...
