WETWINE – Innovations in the application of constructed wetlands at wineries
WETWINE - Innovaciones en la aplicación en bodega de humedales construidos (wetlands)
Objectives
A) Objectives of La Vinyeta:
- HUSB digester: Verify digester efficiency in suspended solid retention at different hydraulic retention times (HRT).
- Check the correct operation and sizing of the system:
o Water line
o Sludge line
B) Objectives in Raimat (Codorniu):
- Management of a conventional sludge dewatering system using an SDRB providing more sludge than in conventional feed.
- Check whether the sludge stabilisation rate from a biological winery WWTP is different from that observed with sludge from an urban WWTP.
- Estimate the design and costs for an SDRB for CODORNIU.
Objectives
- La Vinyeta:
- Digestor hidrolítico (HUSB): Comprobar su eficacia en retención de sólidos.
- Comprobar el correcto funcionamiento del sistema :
- Línea de aguas: HUSB + humedal artificial de flujo horizontal (FH)
- Línea de fangos: humedal de deshidratación de fangos (SDRB) para tratar los procedentes del HUSB
- Raimat (Codorniu):
- Gestionar un sistema convencional de SDRB aportando más fango de lo habitual
- Comprobar si la velocidad de estabilización de los fangos procedentes de EDAR biológica de bodega difiere de la observada en los procedentes de depuradora urbana
- Estimar el diseño y los costes para un sistema de deshidratación con humedales construidos (SDRB) para CODORNIU,
Activities
A) La Vinyeta:
In la Vinyeta was installed a pilot system for the winery's wastewater (dregs) treatment:
A commissioning period was necessary, by which time a 3-point analytical plan had already been carried out: HUSB digester input and output and the HSSF wetland output to assess change in system efficiency.
B) Raimat (Codorniu):
In Raimat, an SDRB was reproduced in eight 1-m3 containers. In four of them, so-called ‘classic’ sludge feeds were applied and in the other four, experimental feeds were applied, initially at triple the volume, although this was later reduced to double
Activities
- La Vinyeta:
Instalación del sistema piloto para el tratamiento de las aguas residuales de la bodega (vinazas).
Ha sido necesario un período de puesta en marcha, momento desde el cual ya se ha llevado a cabo un plan de analíticas en 3 puntos: entrada y salida del digestor HUSB, y salida del humedal de flujo horizontal (FH), para evaluar la evolución de la eficiencia del sistema.
- Raimat (Codorniu):
En Raimat se ha reproducido un humedal de deshidratación de fangos en 8 contenedores de 1 m3. En 4 de ellos se ha aplicado una alimentación con fangos que se ha denominado clásica, y en los otros 4 se ha aplicado una alimentación experimental que, inicialmente, era el triple de caudal, aunque luego se redujo al doble
Contexte
The general objective of the WETWINE project is to test two wetland-based systems built for on-site treatment of wastewater (dregs) and treatment sludge, and their subsequent use on the vineyard itself (circular economy).
In the La Vinyeta winery, located in Mollet de Peralada, a pilot demonstration system was installed in which the wastewater line combined a hydrolytic (HUSB) digester and a horizontal subsurface flow (HSSF) constructed wetland, with the aim of ensuring purified water of sufficient quality for its discharge into public waterways or reuse for irrigation. For the sludge line, a sludge drying reed bed (SDRB) was used, allowing sludge from the digester, once dehydrated and stabilised, to be incorporated into the soil as a fertiliser for the vineyards.
A pilot plant was installed in the Raimat winery, located in Raimat and part of the Codorniu group, to check the effect of innovative management of a sludge dewatering system using a constructed wetland (SDRB). The system was conventionally designed, but the innovative management of the sludge feed sought to optimise the surface area required to achieve stabilisation, in order to reduce required investment costs. The results obtained in this pilot project have been applied to establish the design and cost of an SDRB system to treat all sludge generated in the biological activated sludge plant at the Codorniu winery in Sant Sadurní d'Anoia.
