sampling events (TR x SE) and respective coefficient of variation (CV) for organic matter parameters in water of aquaculture systems: biochemical oxygen demand
(BOD), dissolved organic carbon (DOC), chlorophyll-a, thin sediment (TS) and thick sediment (ThS).
Nutrition composition Rate Crude protein > 42% Crude fat > 5% Crude fiber < 4% Crude ash < 12% Moisture < 10% 2.3.1 Biochemical oxygen demand
After one year, the biochemical oxygen demand
in the mulch treatments were not different from the bare soil control.
With an average treated flow of 75m3 per day (maximum flow of 1525m3 per day) and a BoD (biochemical oxygen demand
) of 890 kilograms per day at the Masham plant, the BoD consent level of 5 mg/I is being met reliably.
Biochemical oxygen demand
(BOD) biosensors have been developed to measure BOD faster than by the conventional method ([BOD.sub.5]), which requires a 5 day incubation of the solution.
The nine test were: temperature, pH, turbidity, total solids, dissolved oxygen, biochemical oxygen demand
, phosphates, nitrate, and fecal coliform.
Other data collected included: water temperature, depth, air temperature, secchi disk, dissolved oxygen, fecal coliform, pH, biochemical oxygen demand
(BOD), bird survey, invertebrates, vegetation and soil.
If the waste water ponds smell, they are not working properly and this directly causes irregular BOD (biochemical oxygen demand
Surcharges are based generally on the biochemical oxygen demand
(BOD), chemical oxygen demand (COD), suspended solids, oil and grease, nitrogen, phosphate and/or pH of the wastewater--and the heavier the level of organic matter in the wastewater, the higher the charge.
A significant problem was the high biochemical oxygen demand
(BOD) caused by chemicals in the wastewater.
Treating 80,000 gallons per day (GPD) of municipal sewage generated by approximately 1,600 users, it takes influent COD (Chemical Oxygen Demand) from 479 mg/l down to 30.4, while BOD (Biochemical Oxygen Demand
) is reduced from 241 mg/l to 7.0; TSS (Total Suspended Solids) from 161 mg/l to 3.00; and Ammonia from 14.6 mg/l to 0.25.
