Where does your water come from

Where does your water come from?

  • Municipal water supply

  • Well

  • Lake

  • Bore hole

  • Cistern

www.sunshineworks.com


What is in your water

What is in your water?

  • Bacteria- e. coli, other coliforms

  • Viruses

  • Parasites – Giardia, Cryptosporidium

  • Pesticides

  • Fecal matter

  • Algae

  • Medications dissolved in drinking water

  • Dissolved solids – salts, minerals, heavy metals

  • Suspended solids – dirt, silt

How filtration systems work

How Filtration Systems Work

  • Ultrafiltration sieves out contaminants by molecular size and weight.

  • Reverse Osmosis sieves out contaminants AND removes dissolved solids (salts, minerals, metals and other ions).

  • Both Reverse Osmosis and Ultrafiltration systems create a barrier to remove contaminants.

  • Pore size is extremely small on reverse osmosis systems and a bit larger on ultrafiltration systems.

  • The pore size affects the amount of pressure, and therefore energy, required to push the water through the membrane.

Ultrafiltration in use

Ultrafiltration In Use

  • Physical barrier to contaminants

  • Removes bacteria, viruses, parasites, pesticides, medications, algae, dirt, silt and other suspended solids

  • Low energy requirement

  • Good for lakes, streams, wells

  • Not for seawater or brackish water

Definition of reverse osmosis

Definition of Reverse Osmosis

  • High pressure feed water is forced against a dense, membrane surface.

  • Water molecules diffuse through the membrane leaving the concentrated salts, other ions and contaminants behind.

Reverse osmosis in use

Reverse Osmosis in Use

  • Removes dissolved salts, minerals, metals and sugars

  • Removes algae, bacteria, viruses, parasites, pesticides, medications, dirt, silt and other suspended solids.

  • Best method for producing very pure water.

  • Only viable method for large volume desalination of brackish water or seawater.

  • Energy intensive

  • Requires prefiltration

Ultra violet light system in use

Ultra Violet Light system In Use

  • Feed water flows past an ultra violet light bulb.

  • The UV rays destroy the DNA in organisms.

  • Effectiveness is determined by water clarity, flow rate and UV ray output.

Ultra violet light pros and cons

Ultra Violet Light Pros and Cons

  • Effectiveness-UV light destroys DNA in bacteria and viruses, effectively killing the organism.

    • The light source must be sufficiently bright and the feed water must have the proper flow rate to be effective. Difficult to determine effectiveness without lab testing.

    • Turbidity-Dissolved solids that turn water dark will also block UV light, making it much less effective.

      • The feed water must be absolutely clear to effectively kill all the organisms.

    • Limitations UV only kills microorganisms.

    • UV cannot remove salts, minerals, heavy metals, pesticides and other inorganic compounds from water.

    • Best as a final stage after ultrafiltration or reverse osmosis.

Ultrafiltration or ultra violet

Ultrafiltration or Ultra Violet

  • Designed for NON POTABLE WATER

  • UF provides a PHYSICAL BARRIER to organisms

  • SystemREMOVES 99.9999% of bacteria and 99.999% of viruses

  • ASIMPLE integrity test validates performance

  • ALOW ENERGY requirement

  • HasPASSED EVP/EVT test protocol

  • For HIGH CAPACITY filtration

  • VeryLOW WASTE stream

  • VerySIMPLE to setup and maintain

  • ProducesCRYSTAL CLEAR WATER

  • Drinking water that TASTES GOOD

Designed for PRETREATED WATER

UV is NOTA BARRIER to contaminating organisms.

Effectiveness depends on water CLARITY, flow rate and bulb position

UV has NO SIMPLE FIELD TEST

Requires POWER to illuminate

Has NO TESTING CLAIMS

Portable units for LOWCAPACITY treatment only

Requires ABSOLUTELY CLEAR water source

Best as final stage
