| ChemicalOxygenDemand / COD | Calc | The oxygen required for chemical oxidation of material in the content (such as by potassium dichromate), reported as a liquid concentration of aqueous oxygen (O2(aq)). This is calculated by multiplying the Total Organic Carbon (TOC) by a user-defined factor which is set on the WaterQuality tab of the Plant Model. |
| UltimateBiochemicalOxygenDemand / UBOD | Calc | The ultimate amount of oxygen required by micro-organisms to break down organic material in the content, reported as a liquid concentration of aqueous oxygen (O2(aq)). This is calculated by multiplying the Total Organic Carbon (TOC) by a user-defined factor which is set on the WaterQuality tab of the Plant Model. |
| BiochemicalOxygenDemand5 / BOD5 | Calc | The oxygen required by micro-organisms to break down organic material in the content in the first 5 days, reported as a liquid concentration of aqueous oxygen (O2(aq)). This is calculated by multiplying the Ultimate Biochemical Oxygen Demand (UBOD) by (1-10^(-5k)), where k is the user-defined rate constant (units /day), which is set on the WaterQuality tab of the Plant Model. This equation assumes that any oxidation is a first-order reaction. |
| Nitrogen (as N Concentration) | ||
| Nitrogen.Total | Calc | The total concentration of nitrogen in the content (both solids and liquids), reported as a slurry (liquids + solids) concentration. All liquid and solids species which contain nitrogen will contribute to this value. |
| Nitrogen.Organic | Calc | The concentration of organic nitrogen in the content based on the user selected organic nitrogen species on the WaterQuality tab of the Plant Model, reported as a liquid concentration. |
| Nitrogen.Ammonia / NH3 | Calc | The Ammonia Nitrogen is the concentration of nitrogen present in aqueous ammonia (NH3(aq)) and the aqueous ammonium ion (NH4+(aq)), reported as a slurry (liquids + solids) concentration. |
| Nitrogen.Nitrite / NO2 | Calc | The Nitrite Nitrogen is the concentration of nitrogen present in the aqueous nitrite ion (NO2-(aq)), reported as a slurry (liquids + solids) concentration. |
| Nitrogen.Nitrate / NO3 | Calc | The Nitrate Nitrogen is the concentration of nitrogen present in the aqueous nitrate ion (NO3-(aq)), reported as a slurry (liquids + solids) concentration. |
| Electrical Conductivity | ||
| Conductivity | Calc | The electrical conductivity of the content. This is calculated by multiplying the Total Dissolved Solids (TDS) by a user-defined ratio which is set on the WaterQuality tab of the Plant Model. |
Qualities Section
The Qualities section appears on the first tab page of the Feeder and Makeup Source models.
This relates to Qualities such as Size Distribution, Lockup, etc. Some of these options are only available as specified in the model's configuration file.
| Tag (Long/Short) | Input / Calc | Calculated Variables / Options |
|---|---|---|
| Qualities | ||
| (These options are only available as specified in the model's configuration file.) | ||
| Lockup.Action | Input | The user may choose to Create the Lockup quality. The 'Lockup' values are set on the 'DLockup' tab. The field displays the actual state of the Lock Up function: If this has been enabled then this will display 'Lockup.Action(On)', otherwise it will display 'Lockup.Action'. Please see LockUp for more information. Note: Lockup must first be enabled on the Plant Model - Qualities Tab before the user may create it here. |
| MatTrack.Action | Input | The user may choose to Create the Material Tracking quality. The 'Tracking' values are set on the 'DTrack' tab. The field displays the actual state of the Material Tracking function: If this has been enabled then this will display 'MatTrack.Action(On)', otherwise it will display 'MatTrack.Action'. Please see Material Tracking for more information. Note: Material Tracking must first be configured on the Plant Model - Qualities Tab before the user may create it here. |
| SzDist.Action | Input | The user may choose to Create the Size Distribution quality. The 'Size Distribution' values are set on the 'DSz' tab. The field displays the actual state of the Size Distribution function: If this has been enabled then this will display 'SzDist.Action(On)', otherwise it will display 'SzDist.Action'. Please see Size Distribution (PSD) for more information. |
| SzSSA.Action | Input | The user may choose to Create the Specific Surface Area (SSA) quality. The 'SSA' values are set on the 'SSA' tab. The field displays the actual state of the SSA function: If this has been enabled then this will display 'SzSSA.Action(On)', otherwise it will display 'SzSSA.Action'. Please see Specific Surface Area (SSA) for more information. |
| Lockup.InUse | Display | Displays the state of the LockUp function: Yes or No. |
| MatTrack.InUse | Display | Displays the state of the Material Tracking function: Yes or No. |
| SzDist.InUse | Display | Displays the state of the Size Distribution (PSD) function: Yes or No. |
| SzSSA.InUse | Display | Displays the state of the Specific Surface Area (SSA) function: Yes or No. |
