Cost Calculation: Detailed Breakdown

ENERGY COSTS

 

LOFT evaporator unit

Power requirement: approx.. 70 kWh/m³

Energy consumptiont: 1,440 m³/year × 70 kWh/m³ = 100,800 kWh

Energy costs: 100,800 kWh × 0.10 €/kWh = 10,800,- €/p.a.

Total =                                                                                                                        10.800,- €/Year

 

Chemical-physical treatment

Power requirement: approx.. 0.2 kWh/m³

Energy consumption: 12,100 m³/year × 0.2 kWh/m³ = 2,420 kWh

Energy costs: 2,420 kWh × 0.10 €/kWh = 242.- €/p.a.

Total =                      ________                                                                                          242,- €/Year



MAINTENANCE AND SERVICE COSTS, OPERATING MATERIALS, CHEMICALS, ANALYSIS COSTS, OFFICIAL APPROVALS:

LOFT-evaporator unit

The amount normally required for maintenance per year is: approx. 4,000,- €

Operating materials, cleaning agents, oil etc. amount each year to: approx. 800,- €

Laboratory analysis and testing are not required

 

Total =                                                                                                                          4.800,- €/Year

 

Chemical-physical treatment

The amount normally required for maintenance per year is: approx. 6,000.- €

 

For chemicals: approx. 5,150,- €

Costs of laboratory analysis and testing: approx. 800,- €

 

Total =                                                                                                                        11.950,- €/Year



PERSONNEL COSTS

 

LOFT-evaporator unit

Required supervision time per evaporator

approx.1 h/week × 45 weeks/year = 45 h/year

Costs: 45 h/year × 40.- €/h = 1,800.- €/year

Required supervision time for peripheral equipment

approx.1 h/week × 45 weeks/year = 45 h/year

Costs: 45 h/year × 40.- €/h = 1,800.- €/year

 

Total=                                                                                                                           3.600,- €/Year.

 

Chemical-physical treatment

Personnel requirements

approx. 20 h/week × 45 weeks/year = 900 h/year

Costs: 900 h/year × 40 € /h

 

Total=                                                                                                                         36.000,- €/Year.



WATER REPLENISHMENT COSTS

 

LOFT-evaporator

The distillate from the evaporation process is recycled back into the production process. This provides savings both in terms of water replenishment and wastewater disposal.

The only water consumed is small amounts entrained in the concentrate, here on the order of approx. 280 m³/year benötigt: 280 m³/year × 3.70 €/m³

 

Total=                                                                                                                           1.036,- €/Year.

 

Chemical-physical treatment

Overall water content sent away in wastewater: 12,100 m³/year

Costs: 12,100 m³/year × 3.70 €/m³

 

Total =                                                                                                                        44.770,- €/Year



DISPOSAL COSTS

 

LOFT-evaporator unit

Disposal of evaporator concentrates

58 m³/year × 80.- €/m³

 

Total =                                                                                                                          4.640,- €/Year.

 

Chemical-physicaltreatment

Overall volume to be disposed of: 60 m³/year

Costs: 60 m³/year × 90 €/m³

 

Total=                                                                                                                           5.400,- €/Year.
