The cost saving on labour and chemicals may be as much as 80 percent.
Consequently,
research shows that compared to other methods, chemical control is by
far the cheapest, also when including indirect costs (treatment costs
drinking water companies). Costs comparison procedures euro cent/m2/year| Method | Productivity(m2/hr)) | Energy consumption(kJ/m2)
