1. The
purpose of the economic, fast, effective and cost-effective RO/
ED/EDI
pre-treatment design of water nanometric polymer are
designed to purify the SDI contaminations of impurities, solids,
suspended solids, algae, bacteria, color, pesticide,
fertilizers, soap,
detergent, oil/grease, ammonia, phosphates, nitrates, urine,
manure,
organic
matter, chemical, toxic chemical, heavy metal clear up to
low
than 3.0~5.0 effectively: to improve the conventional RO/ED/
EDI
pre-treatment to eliminate the bacteria, algae, soap, detergent,
oil/grease, urine, manure, bio-matter, colloid contaminations
being
formed
the viscous cake and scale silt on the RO/ED/EDI unit
[description]
a. The
silt density index are the cake and scale factor to determine
how
much
the concentration of biofoulant, organic foulant, inorganic
foulant
and
silica foulant being accumulated on the RO/ED/EDI unit
b. The
bacteria, algae, soap, detergent, oil/grease, urine, manure,
bio-matter,
colloid
contaminations are the main contaminations being formed the
viscous
cake and scale silt on the RO/ED/EDI unit
2. The
purpose of water nanometric polymer applied at the RO/EDI/
ED
pre-treatment to concentrate, coagulated the contaminations of
impurities, solids, suspended solids, bacteria, algae, color,
pesticide,
fertilizers, soap, detergent, oil/grease, ammonia, phosphates,
nitrates, urine, manure, organic matter, chemical, toxic
chemical,
heavy
metal being transformed into silt sedimentation clear and
purified the silt density index of pre-treatment water low than
3.0~
5.0
of crystal clear water effectively: to purify the pre-treatment
water
up to crystal clear being reduced down SS/BOD/COD/toxic
chemical,
heavy metal contents, eliminated the loads of RO/EDI/
distillation post-treatment design and increased the treatment
effect
and
capacity of RO/ED/EDI/distillation post-treatment design
effectively
[description]
The
silt density index of pre-treatment water are the main guide to
determine
whether the effect of RO/ED/EDI/distillation treatment design
can do cost-
effective treatment and application or not
3. The
purpose of RO/ED/EDI pre-treatment to concentrate, coagulate
and
eliminate the bacteria, algae, soap, detergent, oil/grease,
urine,
manure,
biomatter,
colloid contaminations being formed the viscous
cake
and scale silt on the RO/ED/EDI unit: to increase the flush and
backwash effect to clean the filtrated silt out of RO/ED/EDI
unit,
eliminated the backwash and flush water wasted and recover the
RO/ED/EDI treatment effect effectively
[description]
a. The
viscous cake and scale silt are more less, The filtrated silt
are more
easy
to be backwashed and flushed clear effectively
b.
only needed small volumes of backwash and flush water to be
flushed
and
backwashed the low viscous cake and scale silt clear effectively
c.
prevented larger volumes of backwash and flush water being used
to be
eliminated
desalination cost and expense effectively
4. The
purpose of RO pre-treatment are applied to purify the silt
density
index of the backwash water clear effluent clear effectively
for
water reuse treatment: to do zero-discharge and wasteless
treatment, and eliminated purification cost and expense
effectively
