3. Textile waste water treatment
Effiënt design.
Agriculture and production of food and
beverage claim about 75% of worldwide fresh
water consumption. Second is the energy
industry, using about 15%. The remaining 10%
is split between domestic and industrial users.
• 1 jeans cost:
• 7000-8000 liter fresh water for
grow of cotton
• 500 liter waste water
• 1000 liter flushwater
Within industrial, textile is not only the biggest
consumer, but also one of the most polluting
ones. We will look at the waste water of textile
pre-treatment, dyeing, printing and finishing,
where the water consumption runs up to 10l/
kg for synthetic fibres and up to 20l/kg for wool
and cotton. Textile waste water can have up to
18 parameters to control such as pH, colour,
turbidity, total suspended solids TS, total
dissolved solids TDS, conductivity, dissolved
oxygen, biochemical oxygen demand BOD,
chemical oxygen demand COD, chloride,
nitrates, phosphates, some heavy metals and
odour.

4. Textile wastewater has a high pH value, high
concentration of suspended solids, chlorides,
nitrates, metals like sodium, manganese, lead,
coper, chromium, iron, and high BOD and COD
values. It can also have a dark-brown colour.
The levels of BOD, COD, and TS in textile
preparation and finishing waste water have
been extensively reviewed. The average
concentration and specific loads of TS for main
operations are 16 to 32mg/l for desizing, 7,6 to
17 g/l for scouring, 2,3 to 15g/l for bleaching,
6g to 1,9g/l for mercerizing and 0.5 to 14 g/l for
dyeing.
The conventional choice for textile wastewater
treatment usually consists of coagulation
and​ flocculation, which removes the colloidal
particles of colour, turbidity and bacteria. It
gives rapid removal of colour and significant
reduction of COD, but does not give a
completely satisfactory treatment, especially
not for highly soluble reactive dyes.
Coagulation has for a long time been the only
economical method for colour removal. It is
complicated however because a particular
flocculent is suitable for certain dyes only.
Coagulation can not remove all dyes. Cationic
or basic dyes, used for wool, silk, acrylic and
mod acrylic, do not coagulate at al, making their
removal by coagulation impossible. Acid, direct,
vat, mordant and reactive dyes do coagulate,
but the resulting floc is of poor quality and does
not settle well, even when using a flocculent.
Sulphur and disperse dyes coagulate well and
settle easily. In the presence of surfactants,
the amount of chemicals has to be strongly
increased to achieve satisfactory colour
removal. A disadvantage of coagulation and
flocculation is the generation of large amount of
toxic sludge. The next problem is reappearance
of colour in subsequent steps due to oxidation.
The major problem however is that it cannot
reduce the total dissolved solids TDS, and
sometimes even increases TDS.
An alternative for colour removal is adsorption
by activated carbon, but as a single process
is not efficient. Disperse dyes, vat dyes
and pigments have a low solubility and low
adsorption by carbon at room temperature,
while water-soluble dyes like acid, basic, direct
and reactive are not readily adsorbed by
carbon at al. When used in combination with
polymer flocculation, chemical coagulation or
biodegradation however, adsorption can be
an efficient way of dye removal. The size and
cost of the resulting system is usualy out of
proportion however and pay back is poor.

5. Dannenberg Industries is established in the
Netherlands.The Netherlands has a centuries
long history in developing technologies to
manage water. This technology makes it
possible for Dutch people to live in harmony
with the water surrounding them. Water has
over time been exposed to more and more
pollution by the industry, and nowadays water
has become a valuable commodity. To treat
industrial water to reduce or even prevent
pollution, is a high priority for Dutch research
and development companies.
Dannenberg Industries hereby presents a new
and practical combined technology to treat
waste water from the textile finishing industry.
All equipment has been designed in the
Netherlands by Dutch engineers withworking
experience in the textile processing industry,
leading to practical solutions with high
availability and low maintenance. The filter has
beenundergoing durability tests and has an
extremely long lifetime. The rods do not need
replacement giving high availability and low
operating costs.

6. Membrane filtration technology has been extensively applied in many process
industries to improve waste water. Membranes are classified according to
the size of the particles they separate. Screening is for particles above 1
m. Macro filtration is for 1 mm down to 5 micron, Microfiltration or MF for
5 down to 0.1 micron, while ultrafiltration or UF is used from 0.1 down to
0.001 micron.
F
inally Reverse Osmosis or RO
has range of 0.001 down to 0.001
micron. RO is the only process that
can completely filter out salt and
metallic ions from water, but the
small pore size means that a very high osmotic
pressure is required to force filtration. For sea
water this pressure is 60 to 70 bar. To simplify
filtration sizes in micron, MF is around 0.1, UF
around 0.01, NF around 0.001 and RO around
0.0001. A micron, also known as micrometre,
is a millionth of a metre or 0.01mm. It is
denoted with the symbol μm. Anything below
40 microns in size is invisible to the naked
human eye and requires a microscope to be
seen. UF filters have a pore size between 0.01
to 0.1 micron and an operating pressure of 2 to
7 bar. UF removes suspended solids, colloids,
proteins, bacteria, viruses, plastics, silica and
endotoxins. It produces water with very high
purity and low silt density.
The primary advantages of low-pressure UF
membrane processes are no need for chemicals
like coagulants, flocculants, disinfectants
and chemicals for pH adjustment. UF gives
constant filtration results in terms of particle
and microbial removal. An UF system is
environment friendly, compact and simple to
operate, automate and Next to applications in
the textile industry, membrane filtration is used
in the paper industry combined with membrane
bio reactors, in the poultry industry
combined with ozone disinfection, in the food
and beverage industry combined with UV
disinfection and for oily waste water combined
with ozone and UV treatment.

7. The heart of the system is a tubular filter with rods that have a filter size of
20nm or 50nanomicron.
Our standard size filter system is called “Duo-Cleaner” and consists of 2
tubular filters, each equipped with 19 rods. The capacity for filtering in m3/hr
is based on the pollution level of the waste water. For average waste water
the capacity of a 38 rod system is 3 -7m3/hr (87LPH) . The capacity and
result can be highly increased by combining a centrifuge and a coagulation–
flocculation process with the filtering. A coagulation–flocculation process can
already remove more than 95% of dye in waste water, while also blocking of
filter rods is strongly reduced.
