Publication number: 20200408583Abstract: A foam-level detector is disclosed. The foam-level detector includes mesh disposed on one or more arms attached to a carrier. The carrier is configured to engage a tube so as to be slidable along the longitudinal axis of the tube. The mesh is configured to engage a foam layer such as to float at or near the surface of the foam. The arms may be pivotally attached to the carrier. The carrier may include a magnet configured to magnetically engage a magnet disposed in the tube. The magnet in the tube may be configured to electrically connect two materials, each material having an electrical resistance per unit length of the material. A measure of the resistance of the conductive path formed by the magnet in the tube and the two materials may be used to infer the position of the foam-float along the tube.Type: ApplicationFiled: June 30, 2019Publication date: December 31, 2020Applicant: Probe Technology Services, Inc.Inventors: Rich Thibodeaux, Kent Dawson

Publication number: 20150053619Abstract: Both the hardness and boron content of wastewater may be reduced by contacting the wastewater with liquid sodium silicate (LSS) in an effective amount for such reductions followed by one or both of two additional procedures. The additional procedure may be contacting the wastewater with an Al(3+)-containing compound in an amount effective to at least partially remove silicon from the wastewater, where the contacting is before, during or after the wastewater is contacted with LSS. The second additional or alternative procedure involves, subsequent to contacting the wastewater with LSS, treating the untreated water with an electrocoagulation (EC) apparatus for a period of time effective to at least partially remove silicon from the wastewater. The EC procedure may also further remove boron from the wastewater.Type: ApplicationFiled: August 21, 2013Publication date: February 26, 2015Applicant: Baker Hughes IncorporatedInventors: Jiasheng Cao, Daryl D. McCracken, Evan Kent Dawson
