- Specific details on test material used for the study:
- Batch number : 8613
Manufacturing date : October 25, 2018
Test item physical state : Slight yellow powder
Reception date : November 26, 2018
Theoretical Oxygen Demand : ThODNH4 = 2.416 mg O2 / mg test item
Theoretical Oxygen Demand : ThODNO3 = 2.482 mg O2 / mg test item
Storage conditions : Ambiant temperature ( 20 ± 5°C), Hydroscopic and keep away from light - Oxygen conditions:
- aerobic
- Inoculum or test system:
- activated sludge, domestic, non-adapted
- Details on inoculum:
- The inoculum was a fresh sample of activated sludge and was collected from the aeration tank of a sewage treatment plant receiving predominantly domestic sewage .
Laboratory preparation:
A filtration through a fine sieve (about 1 mm) was performed in order to remove coarse particles. After removal of any coarse particles, the sludge was washed by decantation in a mineral medium until sludge was considered free from excess substrate or inhibitor.
Inoculum pre-conditionning : Pre-conditioning consisted in aerating sludge (in mineral medium) for 5-7 days before the test and at the test temperature.
Sample site : Water treatment plant "STEP de Lille", 33290 Blanquefort (France) Tank 1
Date of sampling : January 24, 2019
Inoculum physico-chemical characteristic:
Suspended solid: 2.9 g/L
pH : 5.9
Dissolved oxygen: 9.1 mg/L
