Reduces ammonia, COD, BOD and TSS in a complete biological wastewater treatment system for wastewater from landfills
Company Name: Stirling Landfill Site – Polmaise
Location: Scotland
Year: 2001
Topic: Leachate treatment from water generated from landfills Fluids that flow through or come out of solid waste. which may contain solutions, suspensions, mixed wastewater from garbage dumps, leachate from garbage, leachate from garbage Highly contaminated wastewater and has acidic conditions seep through or coming out of the landfill There are organic substances, inorganic substances, pathogens and heavy metals. If water from the waste spills contaminates the environment Can cause pollution problems to the surrounding environment, such as leakage into groundwater sources
Goals: Reduce ammonia content, COD (Chemical Oxygen Demand) wastewater measurement from chemical wastewater, BOD (Biological Oxygen Demand) is a measure of wastewater from the water we waste. or from leaf litter and TSS (Total Suspended Solid) all suspended solids in water.
Capacity: 500 cubic meters/day
Water source for treatment: leachate from waste landfills.
Problems encountered:
- Wastewater from landfills has a high content of organic matter and ammonia.
- The contaminated wastewater is located near the water source.
- The oxygen-depleted state creates a nuisance of smell in nearby communities.
Technical solutions:
The process of operation is as follows.
- Provide nutrients and adjust pH (PH)
- Use SBR (Sequencing Batch Reactor: SBR) as a biological treatment system. Removes organic matter and ammonia effectively. (Each process has different oxygen conditions)
- Filter the water with the AFM® filter – a glass filter that effectively removes solids and suspended solids. Residual organic matter and minerals
Result:
| Required Value | Before-Treatment | After-Treatment | |
|---|---|---|---|
| Turbidity (NTU) | 5 | 5 | 3 |
| Ammonia (PPM) | 5 | 1000 | 3 |
| COD (PPM) | 5000 | 5000 | 150 |
| BOD (PPM) | 2000 | 2000 | 7 |
| TSS (PPM) | 1000 | 1000 | 5 |
| TOC (PPM) | 1000 | 1000 | 10 |
| Odor | Minimum | – | Minimum |
