The very low effluent levels of biological oxygen demand, suspended solids, nitrogen, and phosphorus attained by the system indicate that sustainable water recycling and reuse possibilities are within reach for future base camps.
In the third phase of biological treatment combined with air oxidation using organisms present in the waste-water after sedimentation all the 11 samples (100 %) characterized for biological oxygen demand (BOD) Parameter were in the limits of National Environmental Quality Standards (NEQS) and were suitable for disposal into the local water bodies.
Water samples were taken from the sites and the different selected parameters were used for water analysis including pH, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD), Total Dissolved Solids (TDS), Total Suspended Solids (TSS), Chloride and Sulphate.
In technical terms it is referred to as high Biological Oxygen Demand (BOD), which robs the waters of its life-sustaining capacity.
The vital chemical aspects of good water are: Biological oxygen demand (BOD), Chemical oxygen demand (COD) and the value of Totally Dissolved Solids (TDS) of less than 100 to 250 ppm for drinking water and less than 2000 ppm for industrial effluent discharge.
The present investigation has been carried out to analyse the water quality parameters like Colour, Odour, pH, Alkalinity, Total hardness, Calcium, Magnesium, Chlorides, Dissolved oxygen, Biological oxygen demand, Total solids and Total dissolved solids of partially treated distillery effluent and its leachate after passing the effluent through experimental soil profile (Lysimeter).
The Blackstone River is on the state's list of impaired water bodies owing to high biological oxygen demand and suspended solid readings, which come mostly from wastewater treatment effluents and urban runoff and heavy metals from industrial waste, according to Donna Williams, conservation advocacy coordinator at Massachusetts Audubon's Broad Meadow Brook Wildlife Sanctuary and Conservation Center.
The HiPAF system, working in conjunction with a tertiary sand filter, produces treated effluent with Biological Oxygen Demand (BOD) level sub 10mg/l and Suspended Solids (SS) level sub 10mg/l.
A leading manufacturer of decaffeinated and specialty teas reduces biological oxygen demand (BOD) levels with a liquid solid separator.
DO meters can also be used to calculate chemical oxygen demand (COD) and biological oxygen demand (BOD), although titrators and respirometers are also often used for these applications.
Factors contributing to rapid bacterial growth are temperature, retention time, high biological oxygen demand levels, and turbulence.
Alternatively placing material with a high biological oxygen demand at the soil surface such as animal manures or other agricultural wastes will be effective in reducing pyrite oxidation.
