| Parameter | Value | Unit | |-----------|-------|------| | Avg. Daily Flow | 108 | m³/day | | Peak Flow | 13.5 | m³/hr | | BOD Load | 32.4 | kg/day | | Aeration Tank Volume | 210 | m³ | | Clarifier Diameter | 2.4 | m | | Blower Air Flow | 2100 | m³/hr | | Daily Sludge Volume | 4.2 | m³/day |

It is common to add a 10–15% safety margin to account for groundwater infiltration or unexpected surges. 3. Sizing Key Treatment Units stp design calculation

STP design calculations involve several steps to ensure that the plant can effectively treat wastewater and meet regulatory requirements. By accurately estimating the average daily flow, peak hourly flow, hydraulic loading rate, BOD5 removal efficiency, aeration tank design, and sludge production, engineers can design a reliable and efficient STP. | Parameter | Value | Unit | |-----------|-------|------|

The HLR is the flow rate per unit area of the treatment tank. Sizing Key Treatment Units STP design calculations involve

| Parameter | Unit | Example Value | |-----------|------|----------------| | Population Equivalent (PE) | persons | 1000 | | Per capita water supply | LPCD | 135 | | Sewage generation factor | % of supply | 80% | | Influent BOD | mg/L | 300 | | Influent COD | mg/L | 600 | | Influent TSS | mg/L | 350 | | Required effluent BOD | mg/L | ≤ 20 | | Required effluent TSS | mg/L | ≤ 30 |

Once the flow rate is established, individual tanks are sized based on , which is the time wastewater stays in a specific tank. Tank Volume:

The PHF is calculated using the ADF and a peak factor.
