From tapto glass
Aksu installs water filters for homes and offices in Baku. Tap water passes through five stages and reaches the glass as drinking water.

Water travels a long way
Baku's water travels more than 180 kilometres along the Samur–Absheron canal and the Oguz–Gabala water main. It is treated at the plant, but it passes through old pipes and reaches your tap hard and tasting of chlorine.
- 182 km
- Samur–Absheron canal, since 1956
- 262 km
- Oguz–Gabala–Baku water main, since 2010
- Kura
- the city's other source, silty river water
Five stages
Each stage takes out one layer of the water. The order is deliberate: coarse particles are caught first so the fine membrane does not clog early.
Sediment filter
Polypropylene fibre holds back everything larger than 5 micron: sand, rust, pipe debris. It is the first gate, and it protects the filters after it.
Granular carbon
Activated carbon from coconut shell absorbs chlorine and its smell. Chlorine also damages the membrane, so it is caught here.
Carbon block
Compressed carbon filters more finely. It takes out organic compounds, traces of pesticides and any remaining taste.
Reverse osmosis
Under pressure, the water passes through a 0.0001 micron membrane. Dissolved salts, heavy metals, nitrates and bacteria go to the drain.
Mineral and final carbon
Calcium and magnesium go back into the clean water, and the final carbon polishes the taste. The water is soft but not empty.
Aksu RO-5
Under sink, 5 stages
- Stages
- 5
- Output
- 190 l/day
- Tank
- 12 l
- Inlet pressure
- 2.8–6 bar
- Size
- 380 × 420 × 140 mm
The main kitchen system: a separate tap, a 12 litre tank and up to 190 litres of drinking water a day.
Aksu RO-6 Mineral
Under sink, 6 stages
- Stages
- 6
- Output
- 285 l/day
- Tank
- 12 l
- Inlet pressure
- 2.8–6 bar
- Size
- 400 × 420 × 150 mm
A mineraliser is added to the RO-5. It puts calcium and magnesium back into the water, so the taste is softer.
