  • UrinSolve - Urine Odor Eliminator and Uric Acid Degrader for Humans & Animals Datasheet

    Urine is liquid waste excreted by the kidneys and is produced by a process of filtration from blood. This waste is eventually expelled from the body in a process known as urination. Healthy urine is a clear aqueous solution, varying in color from dark yellow to colorless, depending on dilution. The constituents besides water are Urea, Creatinine, Uric acid and Urochrome. Urine also contains ...

  • SCR technology

    How does SCR work? Catalysts perform by lowering the temperature required to allow a chemical reaction to occur. In this case, a reduced nitrogen compound (ammonia or urea) is introduced into the air. The "oxidized" chemical (NO or NO2 or both) then reacts with the other nitrogen compound forming elemental nitrogen and water. The two common sources of neutralizing chemical are either ...
