    Metal foam - Wikipedia

    A metal foam is a cellular structure consisting of a solid metal (frequently aluminium) with gas-filled pores comprising a large portion of the volume. The pores can be sealed (closed-cell foam) or interconnected (open-cell foam).The defining characteristic of metal foams is a high porosity: typically only 5–25% of the volume is the base metal.The strength of the material is due to the

    Filtration is a process that removes particles from suspension in water. Removal takes place by a number of mechanisms that include straining, flocculation, sedimentation and surface capture. Filters can be categorised by the main method of capture, i.e. exclusion of particles at the surface of the filter media i.e. straining, or deposition within the media i.e. in-depth

    May 26, 2017 What is a Septic Tank Pump? A septic tank pump often refers to a submersible water pump that is installed either in the final chamber of a septic tank or in a separate pump sump after the septic tank. A septic tank pump is a small electrical water pump that can be submerged in wastewater. A float switch will turn the pump on and off as the chamber fills with

    Soil Washing

    Jan 29, 2013 Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone
