2
00:00:01,240 --> 00:00:07,379
I'm

3
00:00:07,379 --> 00:00:11,320
theme

4
00:00:11,320 --> 00:00:14,450
do is that when I think it is

5
00:00:14,450 --> 00:00:20,160
0 a lot of people mistake wastewater
treatment biosolids for something

6
00:00:20,160 --> 00:00:23,890
well a bit grilled so we'll use that
stuff

7
00:00:23,890 --> 00:00:28,140
and where did all of the earth you know
goldman's

8
00:00:28,140 --> 00:00:31,320
what you see here is sludge or biomass

9
00:00:31,320 --> 00:00:35,070
did a the you know reproduced

10
00:00:35,070 --> 00:00:39,680
and then guard on primary purpose over
wastewater treatment plant is to

11
00:00:39,680 --> 00:00:41,190
accelerate major

12
00:00:41,190 --> 00:00:45,680
specifically to develop specific
conditions to grow some special bugs

13
00:00:45,680 --> 00:00:49,180
so what are these bugs all the bugs
being grown

14
00:00:49,180 --> 00:00:53,640
in the wastewater treatment plant are
natural and perform the same tasks

15
00:00:53,640 --> 00:00:57,190
albeit in a little less dense
populations in water

16
00:00:57,190 --> 00:01:00,970
and soil around the world ok

17
00:01:00,970 --> 00:01:04,819
the vast majority consist of various
populations of bacteria

18
00:01:04,819 --> 00:01:09,180
who performed the balkan the wastewater
treatment process such as beauty removal

19
00:01:09,180 --> 00:01:12,270
nitrification denies revision phosphorus
uptake

20
00:01:12,270 --> 00:01:16,400
so on generally these bacteria are
pretty boring to look at under the

21
00:01:16,400 --> 00:01:17,630
microscope

22
00:01:17,630 --> 00:01:22,160
but not all the bugs are boring looking
at a sample under the microscope will

23
00:01:22,160 --> 00:01:26,900
in fact reveal some other more exciting
guys better really contribute much to

24
00:01:26,900 --> 00:01:28,200
the overall process

25
00:01:28,200 --> 00:01:33,310
I can play an important role in process
controlling

26
00:01:33,310 --> 00:01:38,010
so who are these guys let me make a note
here that summer these guys will vary

27
00:01:38,010 --> 00:01:39,560
from process the process

28
00:01:39,560 --> 00:01:43,099
so you'll have to get to know your own
population

29
00:01:43,099 --> 00:01:44,330
are

30
00:01:44,330 --> 00:01:48,310
let's take a look at a family called
stocks earlier Spurs

31
00:01:48,310 --> 00:01:51,670
here we have a couple Verizon we're
gonna talk about

32
00:01:51,670 --> 00:01:56,700
first was born to sell 'em these guys
attach onto a block from bacteria

33
00:01:56,700 --> 00:02:03,120
have a retractable tale they can be
pretty quick ok

34
00:02:04,120 --> 00:02:09,759
then there's up a stylus similar but
more to sell ap a stylus also uses tale

35
00:02:09,759 --> 00:02:12,500
to latch onto bacteria flock formations

36
00:02:12,500 --> 00:02:15,590
however this guy's a little bit more
passive and does not have the

37
00:02:15,590 --> 00:02:16,360
retractable

38
00:02:16,360 --> 00:02:17,250
creature

39
00:02:17,250 --> 00:02:20,410
so he doesn't move around as much well

40
00:02:20,410 --> 00:02:24,539
now to the family of them free-swimming
sicilians

41
00:02:24,539 --> 00:02:27,650
these guys also come into view different
varieties

42
00:02:27,650 --> 00:02:31,560
I'll here's an ass but is going these
little critters are

43
00:02:31,560 --> 00:02:35,910
easily identified by their many crawling
likes I'll

44
00:02:35,910 --> 00:02:41,160
say hello to allies oneidas the I don't
know if I pronounce that correctly

45
00:02:41,160 --> 00:02:46,050
lemme and here's trickled field

46
00:02:46,050 --> 00:02:50,479
look at this guy go Duke

47
00:02:50,479 --> 00:02:54,080
I yes and rotifers bizarro

48
00:02:54,080 --> 00:02:58,050
higher life form with cool Harry
Mandelson are much larger than many of

49
00:02:58,050 --> 00:02:59,560
the other bugs we see here

50
00:02:59,560 --> 00:03:03,340
some forms are much more mobile and move
around constantly

51
00:03:03,340 --> 00:03:08,310
others little bit less sagged

52
00:03:08,310 --> 00:03:11,349
on our were friends to me my toons

53
00:03:11,349 --> 00:03:16,509
these tiny worms you can be activer just
swimmingly isley around the neighborhood

54
00:03:16,509 --> 00:03:19,889
can also be remembered europe's
uncertain visions

55
00:03:19,889 --> 00:03:25,709
of nematodes and Rutherford scan be
indicative of an older bacterial biomass

56
00:03:25,709 --> 00:03:30,180
and in wastewater are indicative a
higher degree a purification or seeding

57
00:03:30,180 --> 00:03:33,240
from the cats growth system

58
00:03:33,240 --> 00:03:37,740
another important bacteria to know are
called filamentous bacteria are

59
00:03:37,740 --> 00:03:40,940
these include my birth Rex Parviz lol

60
00:03:40,940 --> 00:03:46,489
Nocardia are by Arthrex old and a whole
bunch of other characters with no names

61
00:03:46,489 --> 00:03:48,020
but are classified as type

62
00:03:48,020 --> 00:03:51,720
light light light light light titled
0914

63
00:03:51,720 --> 00:03:57,030
as you would expect filaments can also
be used to identify conditions are sluts

64
00:03:57,030 --> 00:04:02,160
there's a whole suite a Vindicator tests
available to identify which kinda

65
00:04:02,160 --> 00:04:03,599
present in your sludge

66
00:04:03,599 --> 00:04:08,970
ok so do we care who's in our process
and how many of them there are

67
00:04:08,970 --> 00:04:12,620
great question the answer is yes here's
why

68
00:04:12,620 --> 00:04:17,089
the new research is that England several
years ago

69
00:04:17,089 --> 00:04:21,000
a fight with presence insulated
organisms and treatment plans

70
00:04:21,000 --> 00:04:24,230
but they did was here the effluent
quality

71
00:04:24,230 --> 00:04:28,990
cue the organisms that were present and
they developed table

72
00:04:28,990 --> 00:04:32,110
which correlated which organisms were
present

73
00:04:32,110 --> 00:04:35,339
based upon what the f for quality was
like

74
00:04:35,339 --> 00:04:40,918
by defined the film's and by qualified
and tracking their presence one can use

75
00:04:40,918 --> 00:04:41,978
that information

76
00:04:41,978 --> 00:04:44,990
to understand and identify the

77
00:04:44,990 --> 00:04:48,228
potential effluent quality UNC for
example

78
00:04:48,228 --> 00:04:53,668
Marcella and that the stylus RC normally
with high-quality effluence whereas

79
00:04:53,668 --> 00:04:58,668
of the Q era is seen more often in a
lower quality f1

80
00:04:58,668 --> 00:05:03,060
this English study was updated to
reflect the condition for nitrification

81
00:05:03,060 --> 00:05:07,490
nearly wastewater treatment plant and
what he did was compare

82
00:05:07,490 --> 00:05:12,509
what particular a ciliated organism for
president when nitrification was

83
00:05:12,509 --> 00:05:15,430
occurring and what organisms were
present

84
00:05:15,430 --> 00:05:19,899
when it was no longer nitrifying in the
second study a table was prepared

85
00:05:19,899 --> 00:05:25,139
and yet showed the abundance of
organisms that are more likely to

86
00:05:25,139 --> 00:05:28,360
reflect like if I conditions versus
those that

87
00:05:28,360 --> 00:05:32,250
are present 19 99 fine conditions

88
00:05:32,250 --> 00:05:35,769
it all the studies I it was stressed by
the researchers

89
00:05:35,769 --> 00:05:39,978
and should be understood by anyone using
this identification technique

90
00:05:39,978 --> 00:05:44,709
that the relative abundance will
probably change based upon the specific

91
00:05:44,709 --> 00:05:48,668
operating conditions and the wastewater
stream characteristics

92
00:05:48,668 --> 00:05:52,329
four th in every wastewater treatment
plans as such

93
00:05:52,329 --> 00:05:55,759
the tables provide a good starting point

94
00:05:55,759 --> 00:05:59,350
but should only be used as a starting
point and if

95
00:05:59,350 --> 00:06:03,180
one wants to be certain what's going on
they develop the table

96
00:06:03,180 --> 00:06:06,649
for their old facility using the studies

97
00:06:06,649 --> 00:06:10,569
one can see that when you see printer
searches for a seller

98
00:06:10,569 --> 00:06:14,769
when you see the shell to me because
when you see some types rotifers

99
00:06:14,769 --> 00:06:18,360
you see those only when there's low
beyond the present in the wastewater

100
00:06:18,360 --> 00:06:21,720
that's not always the case but it's
usually an indication that those

101
00:06:21,720 --> 00:06:23,160
conditions

102
00:06:23,160 --> 00:06:26,418
the best solution for any wastewater
treatment plant is to do their own

103
00:06:26,418 --> 00:06:27,279
analysis

104
00:06:27,279 --> 00:06:30,380
prepare their own table %uh and if you
do that

105
00:06:30,380 --> 00:06:34,529
you'll be able to use the I stock silly
it's the rotifers

106
00:06:34,529 --> 00:06:37,870
Andean neighbors to indicate what is
happening

107
00:06:37,870 --> 00:06:41,949
and possibly predict the future and
whether it's going to change

108
00:06:41,949 --> 00:06:45,680
buck as previously touched upon

109
00:06:45,680 --> 00:06:49,459
film in tracking can be another powerful
tool to monitor conditions and

110
00:06:49,459 --> 00:06:51,370
wastewater treatment plant

111
00:06:51,370 --> 00:06:55,000
the abundance and type of elements
present can indicate various process

112
00:06:55,000 --> 00:06:56,120
conditions such as

113
00:06:56,120 --> 00:07:00,199
low dissolved oxygen low after I am
ratio

114
00:07:00,199 --> 00:07:03,899
septet City 0 excessive grease and oil

115
00:07:03,899 --> 00:07:06,939
nutrient deficiency and low pH

116
00:07:06,939 --> 00:07:11,439
I'll checking film it requires the use
of staining tests

117
00:07:11,439 --> 00:07:15,559
tests for sulfur granules cell size and
present some scepter

118
00:07:15,559 --> 00:07:19,189
as well as identification I've attached
growth on the filament day

119
00:07:19,189 --> 00:07:23,800
Jenkins Richard and a agar develop the
chart to use the evaluation process

120
00:07:23,800 --> 00:07:28,619
Jim with sufficient testing the exact
filament can be identified

121
00:07:28,619 --> 00:07:32,240
the dominant some a filament indicates
the operating conditions

122
00:07:32,240 --> 00:07:35,339
if you want to change the biomass change
the underlying condition

123
00:07:35,339 --> 00:07:39,199
which supports that filament for example
type 1701

124
00:07:39,199 --> 00:07:42,509
individual rodeo protect 1851

125
00:07:42,509 --> 00:07:47,050
indicates a low ebb damn ratio so what
physical parameters could very well

126
00:07:47,050 --> 00:07:50,178
correlate with your micro organism
populations

127

better and the better you operate

136
00:08:24,610 --> 00:08:28,119
the cleaner the water is and that makes
it all worth it

137
00:08:28,119 --> 00:08:31,190
