TOC Correlation to BOD or COD

by GE Analytical Instruments     based in Boulder, COLORADO (USA)

Challenge: Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) are traditional parameters analyzed in the laboratory to determine organic matter in water and wastewater. Wastewater facility operators need to have constant data to monitor their discharges and optimize treatment processes (biological treatment, chemical dosing, etc). The requirements of BOD and COD analysis prevent them from being implemented as control parameters, however. The BOD five-day analysis time requirement does not allow an operator to use the data for process optimization and. although COD requires less time than the BOD, its analysis includes the use of hazardous chemicals and has no constant analysis capability.

Odor Scrubbers Applications with Hydrogen Peroxide

by USP Technologies     based in Atlanta, GEORGIA (US) (USA)

Hydrogen Peroxide as a Replacement for Sodium Hypochlorite Hydrogen peroxide may be used in both mist scrubbers and packed tower scrubbers as a replacement for sodium hypochlorite (bleach). Like bleach, the process involves two concurrent mechanisms: 1) absorption of the odors (H2S) into the alkaline scrubbing solution; and 2) oxidation of the absorbed sulfide in solution. Step 1: H2S + NaOH → NaSH + H2O Step 2: 4H2O2 + H2S → H2SO4 + 4H2O Typical dose ratios are 5 parts H2O2 per part H2S or, when used in place of bleach, one gallon 50% H2O2 for every 10 gallons of 15% sodium hypochlorite (NaOCl). This generally translates into a break-even cost scenario. Sufficient caustic soda (NaOH) is added to maintain a pH of 10.0 - 10.5 in the scrubbing solution. There is also in practice a process which uses H2O2 in series with bleach to scrub composting odors. This process relies on a series of three packed tower scrubbers: the first is a pH neutral water wash (to remove ammonia and amine odors); the second uses a conventional caustic/bleach solution in which the bleach is purposely overdosed (to oxidize the complex organic sulfur odors); and the third uses a caustic/H2O2 solution (to remove the unreacted chlorine vapors carried over from the second stage). H2O2 + HOCl → HCl + H2O + O2 Typical dose ratios are 0.5 parts H2O2 per part hypochlorite (OCl-), with sufficient caustic soda (NaOH) added to maintain a pH of 8.5 in the scrubbing solution.

Filamentous Bulking Control with Hydrogen Peroxide

by USP Technologies     based in Atlanta, GEORGIA (US) (USA)

Basis of Control with Hydrogen Peroxide Hydrogen peroxide may be used to correct a serious filamentous bulking situation or, preferably, to prevent one from occurring until adjustments can be made to remove the cause. When applied to the return activated sludge, hydrogen peroxide supplies dissolved oxygen which helps restore the microbial activity necessary for effective operation, while selectively oxidizing the filaments which retard settling. The effective dose of hydrogen peroxide is a function of time and concentration, and varies from plant to plant. To correct a serious bulking problem, immediate results may be obtained by adding 100 - 200 mg/L H2O2 to the biosolids recycle line. Once control of bulking is obtained, the dose may be reduced to 25 - 50 mg/L H2O2 to prevent re-occurrence. Practical Considerations Filamentous bulking of municipal activated sludge is not a normal occurrence, and suggests more fundamental problems may be at work (e.g., low dissolved oxygen, high sulfide input, heavy organic loading, nutrient imbalance, improper sludge age, or rapid changes in influent characteristics). Consequently, the use of chemicals such as hydrogen peroxide to control bulking should be pursued in concurrently with more fundamental corrective measures.
