  • Porirua New Zealand – WaStop® DN225 - Case Study

    Porirua City located 20 km north of Wellington has over 70 storm water outlets into the harbour. A number of these outlets are very flat on their approach to the harbour which generally means they are severely influenced by high tides. The problem with these outlets is that if a rain fall event coincides with a high tide, the ability of the storm water network to discharge is severely restricted. ...

  • Capturing biogas energy to increase your business profits while safeguarding the environment

    Methane is a biogas produced from swine or cow manure, as well as food processing and meat packing waste. Methane is a natural gas, that when left uncollected, contributes to the harmful greenhouse gases in the earth’s atmosphere. When biogas is captured under a cover and becomes concentrated, it creates a corrosive and toxic byproduct called hydrogen sulfide. The gas generates a rotten egg ...

  • 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 ...

  • 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 ...
