WebThe Maine Department of Environmental Protection's maximum holding time for BOD 5 and CBOD 5 analysis is 24-hours from completion of grab sampling or 24-hours from completion of composite sampling to incubation of samples. Data from samples analyzed outside the 24-hour holding time must be “flagged” when reported. WebJan 25, 2024 · #12. Holding Time Index: It is a measurement of time at which the concentration of the added chemical into the cooling water system decreases to 50% of its original value. This happens due to blowdown & drift loss of water from the system plus the addition of new makeup water in the system. The ideal value for HTI is 24 hours. laki-laki adalah pemimpin rumah tangga https://alicrystals.com
