The 16 drops of sodiumthiosulfate converts to 16 x 0.5 or 8 mg of oxygen per liter, and drawing the line between the lower oxygen line on page 30 of the Field Manual for Water Quality Testing and the upper water temperature line yields a value of 87% oxygen saturation since our

Chemical Oxygen Demand (COD) Vial. WTW. Dichromate reactor digestion reagents for fast, easy, safe determination of low-, mid-, and high-range C.O.D. levels in wastewater. Premeasured reagent is packaged in flat-bottom ampules that are compatible with most spectrophotometers. Reagents have a two-year shelf life.

This perforated plate, or any other flat bottom support system, must be designed to distribute the backwash water at the maximum anticipated rate and to withstand the associated uplift force. The maximum backwash velocity at Pomona, 12 gpm/sq ft, although adequate for expanding 16 x 40 mesh carbon, is not sufficient to provide 50 percent expansion of 8 x 30 mesh carbon.
