Proven Disinfection Systems For Wastewater Recycling

A solution by

Waste Water Recycling

• Wastewater created because of household, Industrial or commercial usage needs to be treated before disposal. If not treated, toxic substances find their way into groundwater, lakes and rivers and pollute them, causing grave harm to the environment.

• Also, rather than just wasting this waste water, it can be re-used if properly treated, thus saving substantial amounts of freshwater, which is getting scarcer. Treated waste water can be utilized for gardening, flushing, farming.

Why Is Waste Water Disinfection And Reuse Needed?

• Sources of fresh water are limited Demand of water is increasing with population growth and urbanization

• We experience dry or wet droughts frequently.

• Sending untreated waste water with harmful chemicals and pathogens directly to fresh water reservoirs contaminate

useful water resources.

• UV light is used to effectively disinfect waste water in an environmentally friendly way

• UV treated waste water is recycled and used for gardening, flushing or farming and billions of liters of water saved.

Why Is UV Disinfection Required?

• Wastewater has a very high concentration of disease causing pathogens.

• Typical tertiary treated wastewater samples (before disinfection) on average contain coliform counts of more than 1 million colony forming units per 100 ml of the sample. These cannot be seen with naked eyes.

• Wastewater used for gardening and flushing also requires disinfection due to the high possibility of human contact.

Why Is UV Disinfection Required?

• The United States and many other countries have stringent standards requiring these coliform/fecal coliform counts to be less than 2.3/100ml

• Unfortunately, India currently has no specific standard for bacterial/coliform counts for wastewater reuse applications (only discharge standard exist). Most users/ consultants therefore follow well established USEPA standards for reuse.

What Is UV Technology?

• The UV treatment process is an extremely rapid physical process, that causes a molecular rearrangement of the genetic material, known as DNA, of the microorganism which renders it inactive and incapable of causing infection

What Is UV Technology?

• DNA is the main constituent of all chromosomes of all organisms, known as deoxyribonucleic acid, and is self replicating.

• Once microorganisms are exposed to UV light they are rendered inactive and can no longer replicate – meaning they can no longer produce colonies or cause infection.

• Due to individual cell makeup, different microorganisms require different levels of UV energy for their destruction, this energy level is known as dosage.

Ultraviolet Germicidal Irradiation(UVGI)

• Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses 254 nanometer ultraviolet (UV) light to kill microorganisms.

• It is effective in destroying the nucleic acids in these organisms so that their DNA is disrupted, leaving them unable to perform vital cellular functions.

• UVGI is a proven method for removing volatile organic compounds(VOCs)

• UVGI is also referred as UVC or UV-C

Ultraviolet Germicidal Irradiation(UVGI)

The UV lamp emits powerful ultraviolet light energy at a wavelength of 254 nm.

Alfaa UV’s WWR Series

Unique Features of Alfaa’s WWR SeriesFully Automatic Cleaning

The first of its kind fully automatic wiper systemsWiper systems continuously monitors the condition of the quartz

sleeves and automatically starts the cleaning cycle as soon as it

detects a drop in the intensity, ensuring a fully automated solution

system free of manual operation.

Unique Features of Alfaa’s WWR SeriesUnique Reactor Design

A unique torque controllerIt ensures the wiper system will automatically stop in case of

jamming, thus safeguarding the delicate quartz tubes inside the

reactor.

Dual temperature safety cutoffs ensure automatic power down of the

lamps in case of high temperature buildup due to no flow condition.

Unique Features of Alfaa’s WWR SeriesUnique Reactor Design

Specially designed UV reactorsFor wastewater which contain high levels of dirt, BOD, and suspended

solids.

Product range includes standard models suitable for secondary treated

effluent with BOD/TSS values of 35 ppm as well as for MBR streams with

BOD/TSS <5 ppm

Unique Features of Alfaa’s WWR SeriesIntelliDose

Alfaa Intellidose UV controllerIt features a unique dose mode that can display the actual UV dose being

imparted by the system- in real time!

This informs the user if all the organisms in the water are being

adequately disinfected, triggering an alarm or optionally sending a SMS

in case of a fault.

Advantages of UV Disinfection Technology

• Lower running costo UV disinfection plant is much more economical to run as

compared to Chlorination or Ozonation.

• Simple and fail safe operationo It needs little or no user intervention. The online monitoring

system constantly checks the disinfection process and will alert the user in case of any drop in performance.

• Compacto It is online process and needs no storage tank, saving valuable

real estate.

Advantages of UV Disinfection Technology

• Environmentally Friendly

o It uses no chemicals and forms no by-products unlike Chlorine which produces dangerous carcinogens which pollute our environment.

• Energy efficient

o Alfaa Systems use highly energy efficient UV radiation sources which consume very less electricity as compared to other technologies like Ozone.
