Beer Brewing Industry
The brewing process generally generates unique, high-strength waste
water as a by-product. The waste water typically has a high
concentration of Biological Oxygen Demand (BOD) form the carbohydrates
and protein used in brewing beer. Brewery waste water usually has a
temperature of > 25 °C.
The high level of soluble COD and the temperature makes
brewery wastewater an ideal substrate for anaerobic treatment sometimes
followed by aerobic treatment, depending on the local discharge
requirements.Financial or regulatory pressures can encourage brewery
management to seek capital investment in the waste water treatment area
to reduce annual operating costs. The Upflow Anaerobic Sludge Blanket
(UASB) process and the External Circulation Sludge Bed (ECSB) process
from HydroThane are worldwide proven processes for the treatment of
brewery waste water.
HydroThane plants for breweries are constructed
in such a way (odour -free) that their plants can be located close to
urban areas and have a limited foot print.
