  • Raising Dead Ships: Derelict Vessel Removal

    One of Global’s specialties is vessel salvage – if your vessel runs aground or sinks, we’ll raise it and hopefully refloat it for you. But what happens to the thousands of old, worn out vessels that sit abandoned along the coasts and harbors? Often they sink, where they pose an environmental and navigational hazard. That’s why Washington, Oregon, California and Alaska have ...

  • Cleaning Up With Rent-a-Chemical

    Lease programs are emerging as a safer, more environmentally friendly way to manage chemicals.

  • An Unmatched Combination of Carpet Cleaning Machines and Green Chemicals

    A nice carpet can perk up the appeal of your room. But, as carpet fibers are highly absorbent, they quickly accumulate dust, dirt, oil, and stains. The traditional technique of vacuuming is effective only for removing particles on the surface. Constant scrubbing with harsh brushes can actually do more harm than good to your carpets because delicate fibers can be damaged by excess water and ...

  • Membrane chemical cleaning: why is it required and how is it performed?

    Membrane fouling, defined as the accumulation of particles and organic matter at the surface or in the pores of membranes occurs during membrane filtration. Membrane fouling results in membrane performance loss, i.e. lower rejection values, lower permeate flux and higher pressure drop, which translates into higher operational cost. The extent of fouling depends on the feed quality, operating ...
