DEIONIZED WATER TO RINSE TANKS
2ECYCLE + MlNlMlZE + EVAPORATE ” INSEiY4TERSI (REGENBAW
WASTE) (REE;NT = 0 DISCHARGE
Recycling rinsewaters with Ion Exchange has long been known to reduce waste discharge. Conventional Ion Exchange systems, however, produce large volumes of regenerant waste, making evaporation expensive. The 786 series Rinsewater Recycling Systems from Hydromatix reduce regenerant waste by 98%, making ZERO Discharge feasible. For brochure or technical assistance call:

Method of Treating a Ceramic Body U.S. Patent 5,624,626. Apr. 2.9, 7997 TJ. Walz and /.S. Rossovsky, Seattle, Wash.
A method for treating a ceramic body to provide a wettable surface on the ceramic body comprising immersing the ceramic body in an alkaline hydroxide solution bath; connecting the ceramic body to form an anode of an electrolytic cell; connecting a stainless steel object to form a cathode of the electrolytic cell; imposing a difference
in electrical potential across the electrolytic cell sufficient to remove portions of the ceramic body to provide a pnted surface on the ceramic body, which is wettable; and removing the ceramic body from the alka-
line hydroxide solution bath.
Protection for Anodized Aluminum U.S. Patent 5,624.712. Apr. 29, 1997 G.FI Shulman, assignor to Alumitec Products Corp., Sierre Madre, Calif.
