If you have a historic parts cleaning problem, we’ve probably had some experience cleaning a similar part or material. Since 1951 tilue Wave has been applying the power of ultrasonic cavitation to cleaning aluminum, brass, ceramics, cop per, glass,iron, nickel, plastics, printed circuit boards, steel, zinc and others. If you have a new or ongoing cleaning problem, let Blue Wave make it a thing of the past. Call us at 1-800-373-0144.

Process for Removing Heavy Metals from Water U.S.Patent 5,545,331. Aug. 13, 1996 R.G. Guess, assignor to Romar TechnologiesInc., Danvers, Mass. A process for removing dissolved heavy metals from aqueous solutions, which comprises in a first reaction step, admixing and reacting a first aqueous solution with iron particles at a pH between 0.1-4 to effect precipitation; separating the precipitated heavy metals to form a first liquid effluent; in a second step, admixing with an acidic aqueous solution containing chelated or complexed heavy metals to produce a second liquid effluent containing dissolved heavy metals and dissolved ferrous ions, wherein at least a portion of the dissolved heavy metals are produced by replacement with ferrous ions of the chelated or complexed heavy metals; in a third reaction step, admixing and reacting the second liq-
uid effluent with a water-soluble alkali composition to produce a metal hydroxide slurry containing heavy metal hydroxides and ferrous hydroxide and a third liquid effluent; separating the metal hydroxide slurry from said third effluent; and recycling the slurry to at least one of the first, second, or third reaction step.
