Use of reclaimed water from rose-flower distillation
4 June, 2050
Waste water source
The rose distillery process mixes hot water and rose flowers in a distillation apparatus. This mixture is heated with steam to 110 °C for 150 minutes. During the process a rose distillate is produced. On the other hand, the residues are drained to the receiving shaft where a separating screw press is fitted. A screw press separates the liquid from the solid fraction. The liquid fraction is then transported through a pump to a concrete tank for cooling. Once cooled, it is transported by another pump via metal pipes and hoses or by tank transport to the rose lands.
Distribution System
The water is transported to the fields by gravity flow pipelines, after which surface irrigation is used.
Farming system
Arable farming of roses destined for extraction of rose water and oil.
Waste water treatment description
Nutrient removal : none
Pesticide removal : none
Disinfection : none
Suspended solids removal : none
Other: A screw press seperates the water from the rose pulp used for extraction of oils.
Capacity
The daily wastewater flow accounts for 46.8 m³ of residue juice and 18 tons of solid fraction, both from the production, are released.
Extent of the agricultural beneficiaries
The irrigation is provided to 48 ha of the distilleries own crops.
Costs
The initiative is funded by the company itself.
Type of agreement
No agreement is needed because the water is reused in the same company.
