Controlling <strong>the</strong> “Green Goddess”• Martin Tiernan in deference to <strong>Chlorine</strong> wrote his paper “Controlling <strong>the</strong> GreenGoddess”. He wrote,•“Well may <strong>Chlorine</strong> be called <strong>the</strong> Green Goddess, because of <strong>the</strong> important place sheoccupies in <strong>the</strong> chemical field, and <strong>the</strong> tremendous scope of her influence and power;her ability to do good or evil <strong>for</strong> mankind and <strong>the</strong> ever increasing realm of her activity.Corrosive to practically all things, she is safe and docile when properly handled but canat times be most vexatious and dangerous to those who would woo her without anunderstanding and appreciation of her nature”• Tiernan wrote this years ago and we are still using <strong>Chlorine</strong> today.Page 1Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012.

<strong>Chlorine</strong> Chemistry• <strong>Chlorine</strong> when injected into water hydrolyses as follows:•Cl 2 + H 2 O HOCl + HCl• HOCl dissociates depending on <strong>the</strong> pH e.g. at 7.5 pH• 50% HOCl + 50% OCl - <strong>the</strong> two added are Total Free <strong>Chlorine</strong>• Total <strong>Chlorine</strong> is <strong>the</strong> sum of Chloramines and Free <strong>Chlorine</strong>. Chloramines orcombined <strong>Chlorine</strong> are <strong>for</strong>med when Ammonia mixes with Free <strong>Chlorine</strong>.• It is important that residual <strong>monitoring</strong> devices are capable of providing;reliable and repeatable measurements, when <strong>the</strong> pH varies, without having anaffect on <strong>the</strong> measured residual•CCP – Chlorinination•> 0.5 mg/l with a pH of 6.5-7.5Note: Laboratory and hand held tests (titration and DPD) measure Total Free<strong>Chlorine</strong> and Total <strong>Chlorine</strong>Page 2Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012.

Analysers <strong>for</strong> Control in Water Filtration Plants• What do we want to achieve?• Understand <strong>the</strong> problems of;•Variable lag, fixed lag and cell lag.Cell lag orT90 response<strong>Chlorine</strong>injectionFixed lagVariable lagPage 5Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
Analysers <strong>for</strong> Control in Water Filtration PlantsVariable Lag<strong>Chlorine</strong>injection• Variable lag can provide many problems and it is often too long but can also betoo short• It is recommended that at least 60 pipeline dia. be allowed after <strong>the</strong> injection of<strong>Chlorine</strong> be<strong>for</strong>e a sample is taken. Some installations prevent this and we haveseen distances of between 40 – 10 pipeline dia.• As an example a plant operating at 130 Ml/d thru a 1.0 m dia. pipe would give avariable lag of about 30 seconds, using <strong>the</strong> 60 pipeline dia rule. Obviously if <strong>the</strong>flow reduced by half <strong>the</strong>n <strong>the</strong> variable lag would be 60 seconds• We recommend, <strong>for</strong> good control, that variable lags should be no more than fiveminutesVariable lagPage 6Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
Analysers <strong>for</strong> Control in Water Filtration PlantsFixed Lag• Fixed lag is <strong>the</strong> time it takes <strong>for</strong> <strong>the</strong> sample to get from <strong>the</strong> samplepoint to <strong>the</strong> measuring cell• The fixed lag can be very long depending on <strong>the</strong> length and diameterof <strong>the</strong> sample pipe e.g. a 50m long pipe with a diameter of ½” will havea volume of;V = π r 2 x HV = π 6.25 2 x 50m = 6.13 litres• A typical <strong>Chlorine</strong> analyser cell uses 33l/h<strong>Chlorine</strong>injection° ° ° <strong>the</strong> fixed lag is 11.14 minutes, which is too longFixed lagVariable lagPage 7Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
Analysers <strong>for</strong> Control in Water Filtration PlantsFixed Lag - Improvements• Locate <strong>the</strong> <strong>Chlorine</strong> analyser close to <strong>the</strong> sample point• This is not always possible as <strong>the</strong> sample points are oftenlocated in chambers underground<strong>Chlorine</strong>injectionVariable lagFixed lagPage 8Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
Analysers <strong>for</strong> Control in Water Filtration PlantsFixed Lag - Improvements• Install a by-pass valve to increase <strong>the</strong> velocity of <strong>the</strong> sample in <strong>the</strong>sample line•This method wastes a lot of water as <strong>the</strong> sample by-pass is sent todrain<strong>Chlorine</strong>injectionFixed lag>>By-passvalveVariable lagPage 9Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
Analysers <strong>for</strong> Control in Water Filtration PlantsFixed Lag - Improvements• Install a booster pump and returning <strong>the</strong> sample back to <strong>the</strong> process• This method not only speeds up <strong>the</strong> sample time but also providesadditional pressure<strong>Chlorine</strong>injectionFixed lagBoosterPumpVariable lagPage 10Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
Analysers <strong>for</strong> Control in Water Filtration PlantsCell Lag• This cannot be adjusted by manipulating <strong>the</strong> installation of <strong>the</strong> analyser or <strong>the</strong> pipework• As <strong>the</strong> variable and fixed lags are often out of our control it is important to keep <strong>the</strong> celllag or T90 response as short as possible• For <strong>analysers</strong> that are to be used in a control loop <strong>the</strong>n <strong>the</strong>T90 response should be less than 60 secondsNote: T90 response is <strong>the</strong> time it takes <strong>the</strong> analyser to respondto a 90% step change in <strong>Chlorine</strong> residual in a specified periodCell lag orT90 response<strong>Chlorine</strong>injectionFixed lagVariable lagPage 11Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012.

Analysers <strong>for</strong> Control in Water Filtration PlantsAnalyser Selection•The Depolox 5 cell is able to be connected to <strong>the</strong> Depolox 3+, MFC and <strong>the</strong> SFC•The Cl 2 ++ cell and pH probe is able to be connected to <strong>the</strong> Depolox 3+ and <strong>the</strong> MFC•The SFC BA package includes an SFC electronic moduleDepolox 3+ MFC SFCPage 12Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
Analysers <strong>for</strong> Control in Water Filtration Plants• Variable lags need to be long enough to ensure full mixing of <strong>the</strong> <strong>Chlorine</strong> butshort enough avoiding long sample lines, which create poor control loops• Fixed lags need to be as short as possible and by-pass valves and sample pumpscan be used to reduce delays in long sample lines• Analysers that are used <strong>for</strong> control should have a quick T90 response. TheDepolox 5 and Cl 2 ++ provide a T90 response in less than 20 seconds. The SFCBA provides a T90 response in less than 60 seconds.Page 13Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
<strong>Chlorine</strong> <strong>analysers</strong> <strong>for</strong> <strong>monitoring</strong> <strong>the</strong><strong>storage</strong> <strong>network</strong>• <strong>Chlorine</strong> <strong>analysers</strong> <strong>for</strong> <strong>monitoring</strong> purposes only• Draw a sample from reservoir• Analyse <strong>the</strong> sample• Return <strong>the</strong> sample to <strong>the</strong> reservoirPage 14Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
<strong>Chlorine</strong> <strong>analysers</strong> <strong>for</strong> <strong>monitoring</strong> <strong>the</strong><strong>storage</strong> <strong>network</strong>• Draw a sample from reservoir• Where <strong>the</strong> sample is drawn from willdetermine how it is handled. If <strong>the</strong> sample istaken from <strong>the</strong> base of <strong>the</strong> reservoir <strong>the</strong>n<strong>the</strong>re will usually be sufficient pressure todrive <strong>the</strong> sample thru <strong>the</strong> cell. If <strong>the</strong> head from<strong>the</strong> reservoir is low or <strong>the</strong> sample is takenfrom <strong>the</strong> top of <strong>the</strong> reservoir <strong>the</strong>n a boosterpump should be utilised.• We recommend that a pressure of at least 5mhead is available to <strong>the</strong> cell.Page 15Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012. All Rights Reserved.Water Technologies
<strong>Chlorine</strong> <strong>analysers</strong> <strong>for</strong> <strong>monitoring</strong> <strong>the</strong><strong>storage</strong> <strong>network</strong>• Analyse <strong>the</strong> sample• As <strong>the</strong> analyser is only <strong>monitoring</strong>, <strong>the</strong>T90 response is not as critical. There<strong>for</strong>e<strong>the</strong> use of buffered cells can be avoidedand membrane style <strong>analysers</strong> can beselected. The T90 response from a<strong>monitoring</strong> analyser should be less than180 seconds. As <strong>the</strong> sample does notcontain any buffer <strong>the</strong>n <strong>the</strong> sample drainis allowed to be collected and <strong>the</strong>nreturned to <strong>the</strong> reservoirPage 16Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012.

<strong>Chlorine</strong> <strong>analysers</strong> <strong>for</strong> <strong>monitoring</strong> <strong>the</strong><strong>storage</strong> <strong>network</strong>• Return <strong>the</strong> sample to <strong>the</strong> reservoir• The discharge from <strong>the</strong> cell is typicallybetween 6 – 33 l/h. The sample water is easilycollected in a tank, which is monitored <strong>for</strong> lowand high level by level switches. The levelswitches provide signals to a booster pump,which in turn draws water from <strong>the</strong> tank andreturns it to <strong>the</strong> reservoir.Page 17Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012.

Monitoring of <strong>the</strong> reticulation <strong>network</strong>•Typically <strong>analysers</strong> have been located inroadside cabinets as shown here. Theyusually require a concrete pad and need tobe connected to mains voltage. The<strong>analysers</strong> are <strong>the</strong> same as those used in<strong>the</strong> <strong>storage</strong> <strong>network</strong>. The samples have tobe returned to <strong>the</strong> main due to <strong>the</strong> largequantities of sample water used•For years water companies have beenlocating pressure transmitters belowground. These battery operated devicestransmit <strong>the</strong>ir in<strong>for</strong>mation using GPRS,which is typically uploaded to web serversand SCADA.Page 23Siemens Water & Waste Water AcademyFor internal use only / © Siemens AG 2012.
