Treatment of specific effluents
The reed bed filter process is gradually being used for industrial wastewater treatment. We are actively participating in this development through our R&D Service.
Château Montredon
Château Mont Redon is a 200-ha. vineyard that produces 6000 hectolitres of wine a year.
The Chateau is composed of three domains, in Chateauneuf-du-Pape, along the banks of the Rhône and in Lirac.
The domains have to submit declarations indicating that they respect the environmental protection regulations.
To handle their own vineyard wastewaters, the managers decided to install a waster water treatment plant, and chose the reed bed Filter system designed by SINT engineering firm and constructed by Epur Nature:
- A horizontal reed bed filter to treat effluents from the vines’ plant health treatments
- A system composed of four parallel drying beds to dehydrate biological sludge from cellar effluents after they have passed through
a closed aeration tank and a “biological disk” wheel.
- Two parallel vertical filters used alternately during the first treatment of household wastewaters.
- Combined final treatment of winery effluents and household wastewater during last horizontal filtering prior to discharge in the
surrounding environment.
The different wastewaters from the domain and the rainwaters are collected in separate systems.
PURIFICATION OF WINERY EFFLUENTS
In this operation, data on household waste are insignificant (and thus not recorded) in comparison to data on the volume and load of winery effluents.
Step 1 : The screened effluents are collected in a closed tank with air blown in for slight aeration in order to limit offensive odours.
Step 2 : The aerobic biological treatment is carried out in a biological disk-type Stahlermatic reactor that operates non-stop
(designed and built by ALBA).
Step 3 : The final step prior to discharge in the natural environment is carried out using reed planted in a horizontal filter.
Regulations concerning discharge into the natural environment:
pH : 4 à 8.5 SS : < 100 mg/l COD :< 300 mgO2/l BOD5 : < 100 mgO2/l.
The waste water treatment plant has been operating since 2002.
