FBR Container, Buffer Aeration System, Dissolved Air Flotation Unit (DAF), Big Bag Dewatering Unit, ClearFox® Eccentric Screw Pump
SITUATION
A tobacco company from Egypt contacted us to help solve their industrial waste water treatment problem.
PROBLEM
Tobacco wastewater comes from two sources: industrial wastewater which accounts for around 50-60% of the wastewater. It comes from washing water and cleaning of the silk making/roll-adhesive equipment. The other 40-50% comes from domestic use and miscellaneous wastewater.With a normal waterflow of 5m³/day and a peak of 10m³/day the average wateflow should not exceed 7,5m³/day.There was an existing buffer tank with three chambers already installed with following data:
11510mg/l BOD influent – [Effluent Limit 600mg/l]
19184mg/l COD influent – [Effluent Limit 1100mg/l]
1960mg/l TSS influent – [Effluent Limit 800mg/l]
100mg/l Oil influent
3.9mg/l Total P influent
pH 4.36mg/l influent
SOLUTION
Our specialists designed a solution incorporating chemical pretreatment, DAF and a sludge big bag dewatering unit in the first chamber. In addition to this, a FBR biological industrial waste water treatment system with a clarifier in the second chamber was specified.
Energy consumption:
| Consumer | kw | Running time in (h) | Consumption(kWh/d) |
| DAF complete (dosing pumps, multiphase pump, compressor) | 4 | ~10 | ~40 |
| Aeration fixed bed reactor | 2,2 | ~16 | ~35,2 |
| Control unit, room equipment | 1,5 | ~10 | ~8 |
| Option aeration system | ~1,5 | ~10 | ~ 15 |
ADVANTAGES
Our Clearfox products are developed and manufactured in Germany. All of our treatment modules have been tested and have the highest standard on technology while being easy to maintain. Our price/quality relation was the best compared to other competitors which was the crucial point for the tobacco company to choose us above others.Other advantages of the products:
- Reduced energy costs because of power save mode
- Big efficiency rate for every process; for example special fine bubbling aeration
- Less noise as everything is housed within a container
- Low costs for projecting and construction management
- Absolutely odorless
- Highly efficient in COD/BOD/FOGs reduction (up to 99%)
- Totally automatic operation
- Two stage DAF – not just single stage like standard DAF systems
In 2022 the ClearFox® expanded the DAF system with an FBBR module. Now the treated wastewater is used for irrigation. Read more here!
