Solution Cases: Livestock Processing Wastewater Solutions 20 M³/D Capacity
Solution Case: MBBR Mini Plant
Start Up: June 2016
Capacity: 20 m³/d
Project Background
The growing pollution of our environment is a problem concerning every one of us. Especially the pollution of lakes and rivers has increased to alarming proportions over the last few years. At the same time, legislation is demanding more and more of wastewater quality. Therefore the use of innovative technologies has become indispensable for future-orientated wastewater treatment.
The MBBR mini plant is designed and manufactured, the advantages are as below:
* Easy to transport, move, and expand.
* Quick start-up - fully automatic and mess-free.
* No additional Shelters are needed.
* Any capacity, any effluent requirements.
* No odor - low power requirements.
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 MBBR mini plant as follows:
| Parameter | Unit | Inlet Values | Outlet Values |
| COD | mg/L | 3500 | 60 |
| BOD5 | mg/L | 2500 | 20 |
| NH4-N | mg/L | 100 | 10 |
| OIL | mg/L | 15 | 10 |
Solution
This MBBR mini plant consists of three systems: 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, such as micro suspended matter, colloid, oil and grease. The third or biological treatment stage is designed to substantially degrade the wastes in the sewage water.
