タイトルまたは説明
Sludge dewatering machine is widely used in breweries. It can
improve water quality, reduce energy and material consumption,
reduce pollutant emissions, and achieve the goal of energy
conservation and emission reduction. Multi disc screw press has
simple structure, convenient operation, low maintenance cost, large
processing capacity, energy saving and environmental protection,
and is suitable for the needs of different fields. Sludge
dewatering equipment has significant advantages and is suitable for
breweries of all sizes. Apoaqua can customize and manufacture
complete equipment for customers around the world.
Advantages of Sludge
Dewatering Machine in Treating Brewery Wastewater
Beer is a beverage, which has high requirements for environmental
hygiene. The front-end treatment can be done with underground
equipment or civil engineering pools. The sludge dewatering section
must be ground equipment. Sludge dewatering equipment has its own
spray cleaning device, which will not damage the environment
again.
Energy consumption cost issue. The energy consumption of sludge
dewatering machine is 0.*5Kw**5.9Kw, which is low. It is made of
**4 stainless steel and does not require filter cloth replacement,
reducing operating costs.
The sludge dewatering machine is small in size and occupies a small
area under the same processing capacity. It does not require
full-time personnel to supervise it during continuous operation,
which is more friendly to small wineries.
Characteristics of brewery
wastewater
Sources of brewery wastewater:
- Malt workshop (malt soaking wastewater).
- Saccharification workshop (saccharification, filtration and
washing wastewater).
- Fermentation workshop (fermentation tank washing, filtering
washing wastewater).
- Filling workshop (bottle washing, sterilization wastewater and
beer flowing out of broken bottles).
- Cooling wastewater for production, etc.
Difficulties in brewery wastewater treatment:
The amount of water used in the beer production process is very
large. Especially in the brewing and filling processes, a large
amount of wastewater is generated due to the large amount of fresh
water used. Due to the large number of beer production processes,
the water consumption and water quality per ton of beer in
different breweries vary greatly. Domestically, the total water
consumption per ton of beer from saccharification to canning is
****0 tons.
Harm of brewery wastewater to the environment:
According to national regulations, beer wastewater cannot directly
enter rivers, lakes and seas. If the brewery wastewater is not
treated, the BOD value of **0 tons of beer produced each year is
equivalent to the BOD value of *4,**0 people's domestic sewage. The
suspended solids SS value is equivalent to the SS of 8,**0 people's
domestic sewage. The degree of pollution is quite serious, so the
beer wastewater must be treated to a certain extent.
