00:06In the past, we have been taking a while.
00:10It is a 90 L per capita per day.
00:13It is a 135 L per capita per day.
00:17For our Domestic Use

01:12Compared to all other disinfection technologies
01:15Chlorine Disinfection
01:17Which is very cheap and economical
01:18And
01:19That's why we use chlorine
01:21Disinfection
01:22Commonly

02:11to disinfection.
02:13The benefit of the direct benefit is that,
02:16if there is a waterborne disease,
02:21the microorganisms, bacteria, and virus will kill.
02:26If you do disinfection,
02:29you will get a lot of help.
02:32If you have cholera, typhoid, diarrhea, dysentery,
02:37then, we use disinfection directly to disinfection.
02:44But, it is 120 years old.
02:46It is indirect and impacted.
02:50Chlorine, with natural organic matter,
02:53has reacted to disinfection byproducts,
02:56a unwanted byproducts.
02:59U.S. EPA,
03:01a lot of disinfection byproducts.
03:06In this case,
03:08there are two types of disinfection byproducts.
03:11One is trihalomethines,
03:13and one is halocytic acids.
03:16So, what is our BIS standard?
03:19The drinking water quality standard is
03:21chloroform 200 mcg per litre,
03:23bromoform 100 mcg per litre,
03:25bromodichloromethane 100 mcg per litre,
03:29and di-bromochloromethane 60 mcg per litre.
03:33And all these are trihalomethines,
03:36less than 100 mcg per litre.
03:40In this case,
03:42we have a high acid acid,
03:44which is the standard standard.
03:47But,
03:48in this disinfection byproducts,
03:50microgram per litre,
03:52this is why we have greater concern to human health.
03:57This is the suspected carcinogens.
03:59That's why we have to avoid disinfection byproducts.
04:07In this disinfection byproducts,
04:09every quantity of pharmacos,
04:11there is a complex chemistry.
04:14There are many factors that influence.
04:17pH, reaction time, chlorine dosage,
04:20and disinfection time,
04:23all the organic matter,
04:25there are many factors that influence.
04:29So,
04:30in this case,
04:33we are supposed to move on to better, cleaner disinfection technologies.
04:51So,
04:52chlorination,
04:53other alternate disinfection technologies,
04:55to move on to correct time.
04:58UV disinfection,
05:01and ozone disinfection,
05:04there are advanced oxidation processes.
05:08However,
05:09there is a large quantity of water disinfection.
05:13We have to optimize the cost.
05:16That's why
05:18we have a novel
05:21UV photo reactor design.
05:24UV with ozone combined.
05:27We have designed the disinfection system.
05:30So,
05:31that there is no formation of disinfection byproducts.
05:34The cost of work out,
05:37for 10 MLD plant,
05:40the cost of conventional chlorine disinfection,
05:44the cost of equivalent chlorine disinfection.
05:46That's why
05:47it has a small report.
05:48That's why
05:49the technology
05:50could be considered
05:53as an potential alternative
05:55to the chlorine disinfection technology.
05:56This one
05:58will be applicable to water treatment.
06:00It is also
06:02for waste water treatment.
06:03Waste water treatment plant
06:05In the waste water treatment plant,
06:06the wastewater treatment plant,
06:07in the river or land,
06:08in the land,
06:09can be addressed to the disinfection
06:11and kill microorganisms.
06:13So, there is also a chlorine disinfection that is in the case of the disinfection byproducts. So, for that, there is also a chlorine with the organic disinfection byproducts. So, for waste water disinfection, UV-based advanced oxidation process, we will do it in the case of the disinfection.
06:33UV disinfection, for small scale, decentralized, in a high school level, it is proven now. That is why we use UV disinfection.
06:46Chlorine disinfection, after the disinfection, there is a residual chlorine in 0.1 to 0.2 mg per litre treated water. Whereas, UV disinfection, there is no residual effect.
07:01Then, chlorine disinfection is done by DBP. UV disinfection is done by DBP. UV disinfection is done by DBP.
07:10Ozone UV is done by disinfection byproducts.
07:15The two are the shortest time period, very rapid microorganisms.
07:21That means, reactor design is correct. We will do large quantity of water or waste water treatment.
07:29So, we can use this technology as well.
07:33We can use this technology as well as we can use this technology as well.
07:36If we can use this water treatment, we can use these diseases as well as we can use it.
07:43all these chemicals are destroyed by disinfection.
07:47We generate waste water that we use to generate waste water.
07:55100 liters per capita per day,
07:58100 liters per day,
08:02100 liters of waste water.
08:05There are millions and millions of microorganisms.
08:12So, waste water treatment,
08:15without disinfection,
08:18the river will be polluted.
08:24Therefore, waste water treatment,
08:27the disinfection will be done.
08:30In the R.H.E.,
08:32the Central Government,
08:33the Central Public Health Environment Engineering Organization,
08:36they are responsible for bringing up the design guidelines
08:39for water treatment units and waste water treatment units in India.
08:43So, they are aware of this technology,
08:47this lab scale level,
08:50comprehensive study,
08:52and kinetics and cost economics work out.
08:56With funding,
08:58the research team has done,
09:00the results will be given
09:02which is under consideration with the CPHEO.
09:04Once they approve,
09:06they publish the design guidelines manual.
09:08and publish the manual.
09:10And,
09:11let's publish the manual.
