Chemical Oxygen Demand Reagent Tubes

This CAI Method SB1500 determines COD by oxidation of waste water sample with potassium dichomate followed by measurement of the decrease in the amount of the oxidant present (for the low range determination), or by the measurement of the increase of the amount of reduction of product formed (for the high range determination). Both of these chromium species are colored and are measured using a spectrophotometer. The CAI Method SB1500 may be used in place of other NPDES-approved spectrophotmetric methods for the determination of COD.

Waterra Groundwater filters use a polyethersulphone 0.45 micron media with a unique open pleat geometry providing excellent partical retention with prolonged media life. These filters also offer more flexibility then the competitors with the compund inlet. It has both a 3/8" threading with 1/2" hose barbs allowing the filter to attach easily to a varity of pumps and tubing.
