The combination allows for a high solids detoxification treatment.

Abstract: A system (10) and methods of use for determining the level of a body of liquid (16), e.g., a chemical, in a storage tank, irrespective of the specific gravity of that liquid. The system (10) comprises a pressure transducer (22) and an elongated tubular, flexible sheath (24). An operating liquid (26) of lower specific gravity than the body of liquid (16) is disposed within the sheath (24). The transducer (22) is also disposed within the sheath adjacent the bottom end. The sheath (24) is immersed in the body of liquid (16) so that its top end (28) is above the liquid's surface. The pressure applied to the sheath (24) by the liquid (16) causes the sheath to collapse to a minimal internal cross sectional area, whereupon the operating liquid migrates up the sheath to form a very thin column (44). The operating liquid forming a pool (46) is located at the top of the very thin column (44). Thus, the sheath expands outward adjacent the surface (16A) of the body of liquid to retain that pool.

Abstract: The present invention utilizes low volatility amines or alkanol amines to control caustic corrosion which can take place when a boiler system, treated with a coordinated phosphate/pH program, is "out of control".N-substituted hydroxyalkyl piperazines are also capable of mitigating caustic corrosion in coordinated phosphate/pH programs. Combinations of the compounds of the present invention and phosphate have also been shown to be efficacious at mitigating caustic corrosion in coordinated phosphate/pH programs.
