Background
The growing pollution of our environment is a problem concerning everyone of us. Especially the pollution of lakes and rivers has increased to alarming proportions over the last years.
The miniplant be desinged and manufactured, the advantages as below:
• Easy to Transport, Move, and Expand

Challenge
Incoming wastewater is the livestock processing wastewater. This treatment is designed to remove Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), ammonia and from the wastewater.
The Inlet and outlet design values of the MiniPlant as follows:
| Parameter | Unit | Inlet values | Outlet values |
| COD | mg/L | 3,500 | 60 |
| BOD5 | mg/L | 2,000 | 20 |
| NH4-N | mg/l | 100 | 10 |
| OIL | mg/l | 15 | 10 |
Solution
This MiniPlant consists of three system: DAF, MBBR and Clarifier.
For the first stage, the grid be used to remove the larger impurities. The second DAF (Dissolved Air Flotation) treatment stage could remove the relative density which is close to that of water. The third or biological treatment stage is designed to substantially degrade the wastes in the sewage water.
