  • The natural way to clean wastewater

    John Todd founded Ocean Arks International in the 1980s, where he started to experiment with processes that mimic natural ways to purify wastewater. He built a greenhouse and ran sewage through a series of tanks, with plants suspended in the flowing waters, and constructed marshes made of sand and gravel. No chemicals were added, but plenty of aquatic creatures from snails to small fish were ...

  • Monitoring flammable gas in boiler houses

    The most common fuels in use for space and water heating are Oil, Natural Gas and Liquid Petroleum Gas (LPG). By far the most popular, clean and cost effective solutions are utilising Natural Gas or LPG. The traditional safety measure derived from the time of oil fired boiler houses is the use of a fusible link placed above the each boiler. The fusible link is intended to melt if it becomes ...

  • Offshore oil spill clean up case study

    In the event of a major incident occurring offshore, for example a tanker casualty running aground or breaking up for any reason, it is of paramount importance to deploy emergency response to protect and save human life. Once this has been done an assessment of the casualty should be made on whether it is possible to salvage the vessel and its contents and to assess the type and amount of oil ...

  • Air Monitoring for the Gulf Oil Spill

    Ambient air monitoring is a priority in the ongoing efforts to contain and manage the oil spill from the Deepwater Horizon in the Gulf of Mexico. The following provides information about the kinds of airborne contaminants that are currently being monitored in the Gulf, how they are collected and how they are analyzed. For a given project, a suitable sampling plan – developed by ...


  • Air Separation Plants and the Use of Oxygen Monitors

    Air separation plants are critical for many different industries, from clean energy to manufacturing. Nowadays, cryogenic is the most common type of distillation used to separate air into its component gases - nitrogen, oxygen, and inert gases including helium and argon. If your industry relies on air separation for product development or manufacturing, then knowing how the process works is ...

  • Analysis of monitoring results of the separation and greywater treatment system at Chester Woods Park, Olmsted County, Minn.

    Introduction In 1993, Olmsted County installed an advanced individual sewage treatment system (ISTS) at the caretaker's residence at a County-owned park to demonstrate waste load reduction and downsizing of drainfield area. The subject system has two components--1) a composting/vermiculture blackwater system and a 2) aerobic graywater treatment system. The separation of the high strength ...


  • Case study - Safety, Protection against corrosion and cabinet pressurisation in refineries

    The environment in a refinery is highly corrosive. This makes it necessary to deploy control systems not only to protect staff but also to protect the equipment controlling the processes, in order to ensure their reliability. Bioconservacion has equipment that is specially designed for the safety of staff, and for protecting against corrosion in control rooms and cabinet pressurisation equipment. ...
