  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • Top 10 Reasons to Choose a Diaphragm Actuated Control Valve

    Every water system typically consists of piping networks that distribute water from a source or storage reservoir to the end users. This frequently requires miles of piping mains along with pumps systems and controls that all have to be monitored and controlled somehow. Whether this control is to regulate pressure, a level or a flow, this usually will require some form of a ...

  • Self-Cleaning Pre-Filtration for RO Membrane Systems

    ABSTRACT A few years ago physical processes could only remove suspended solids from a water stream. Recent advances in technology now allow the removal of selected molecules and ions from a water stream by physical means using membranes. The membrane process has recently become very efficient and economically feasible for many industrial, commercial, municipal and even residential customers. ...

  • Introduction to the BioCar Nature Based Transportation Systems

    The people of the world are rapidly growing aware of the full impact of current transport systems upon their safety, economy, health and environment. This has not been lost on the major auto companies who have spent millions of man-hours and billions of dollars over the last decade in pursuit of the Next Generation Vehicle. But they have little to show for their efforts having been increasingly ...

  • AquFlow (formerly Hydroflo) metering pump helps make fireproofing system a success

    Problem: Part of developing innovative technology is making its application as easy for the user as possible. So when W.R.Grace&Co.-Conn. went to market with an accelerator for its Monokote family of fireproofing products, a key priority was making the system user-friendly. The accelerator can save users money because it makes the product more efficient to apply and increases ...

  • New developments of vibratory feeders for large bulk material reclaim systems

    Summary The efficient economical storage, movement, control and blending of large tonnages at coal handling installations such as mines, power plants and port facilities require new and improved designs of vibratory equipment.

  • Wind Generators as Role Models

    Advanced speed control methods are available for the regulation of wind generators. Working together with SET Sustainable Energy Technologies GmbH, Sulzer made use of one of these new concepts on pumps for the first time and implemented it with great success on a feedwater pump in a refinery. Unregulated pumps consume unnecessary drive energy when demand fluctuates. By controlling ...

  • Invasion of the non-indigenous nuisance mussel, Limnoperna fortunei, into water supply facilities in Japan

    ABSTRACTThe aquatic nuisance mussel, Limnoperna fortunei, arrived in Japan before 1987 possibly with the Asian clam imported as food from mainland China. Now the mussel’s distribution has spread to two river systems in central Japan. Water authorities reported several cases of damage caused by L. fortunei. Most cases of damage were caused by dead mussels clogging small diameter pipes for raw ...
