The Power of Trio Ozone Chlorine Advanced Oxidation

DEL Ozone A Brief History Formed in 1975 Headquartered in San Luis Obispo, California Original Equipment Manufacturer Family of Ozone products for the residential and commercial Swimming Pool Industry based on thirty years of continuous research, experience, and applied ozone and chemical technology in swimming pools Expanded Ozone product line into Food Safety in 1995

Ozone A Brief History 1840 Identified by German Scientists 1906 Ozone Drinking Water Purification Plant in Nice, France 1937 Commercial Pool Installs Ozone, Mohawk Cruiser, Bryam, NJ 1940 Ozone Used to Purify the Indoor Pool Water at the U.S. Naval Academy in Annapolis, MD 1984 Olympic Games Competition Pools Began Ozone Purification

Ozone A Brief History Continued 1976 EPA Approves Ozone as an Antimicrobial 1982 IBWA Bottled Water Specifications Approve Ozone as an Antimicrobial for Product and Disinfectant for Filler Lines 1999 EPA Lists Ozone as Safe for Surface and Ground Water 2001 FDA/USDA Approve Ozone as an Antimicrobial Food Additive 2001 FDA/USDA Approve Ozone as a Food Surface Disinfectant 2002 USDA National Organic Program Allows Ozone as an Antimicrobial Food Additive and Food Surface Disinfectant

Ozone A Brief History Continued DuPont selects DEL Ozone as its North American Ozone equipment supplier for the Food Safety Industry Ozone is a well established and scientifically proven technology

What is Ozone Ozone is a gas that is used alone as Gaseous Ozone or injected into water, becoming Aqueous Ozone Ozone is a Strong oxidizer/sanitizer (1 PPM O 3 = 200 PPM Cl) Occurs naturally in Earth s atmosphere UV from the sun Electrical Energy from lightning Each ozone molecule consists of three oxygen atoms (O 3 ) Ozone has a clean, fresh scent noticed after a Thunderstorm The Ozone layer protects the Earth from harmful UV Rays

Ozone Produced by Ultraviolet Light Energy UV Ozone Creates low amounts of Ozone at very low concentration Ozone concentration output 300-500 PPM (Gaseous) Electrically inefficient to operate Decreasing ozone output over ~9000 hour lamp life UV Ozone was principally used in the Pool and Spa industry in the 1980 s and 1990 s

Ozone Produced by Electrical Energy Corona Discharge (CD) Ozone Creates high amounts of Ozone at very high concentration Ozone concentration output 1,500-35,000 PPM (Gaseous) Electrically efficient to operate More consistent ozone output over life of cell Introduced to the Pool & Spa industry by DEL Ozone in 1999

How Ozone is Made Oxygen molecules (O 2 ) are split, resulting in two individual oxygen atoms (O 1 ). Oxygen atoms (O 1 ) unite with other oxygen molecules (O 2 ) to produce OZONE (O 3 ). (O 1 ) + (O 2 ) = (O 3 )

How Ozone Works The third oxygen atom is held by a weak single bond. An oxidation reaction occurs upon any collision between an ozone molecule and a molecule of an oxidizable substance The weak bond splits off, leaving oxygen, O 2, as the only by-product. During an oxidation reaction, organic molecules are destroyed & dissolved metals are rendered insoluble. Weak Bond Oxidizable Substance Oxygen (O 2 ) Algae Bacteria Viruses Fungus Molds Suntan Oils Body Oils Sweat Urine

How Ozone Works in Pools Ozone is the Primary Sanitizer (continuous operation) Ozone Kills all known microorganisms (no resistance to kill) Effective against microorganisms (1 PPM O 3 = 200 PPM Cl) Provides Micro-flocculation of organics, improving water clarity Oxidizes dissolved minerals, allowing filtration to remove them Improves water quality by increasing O 2 level in the water Reduces the need for Chlorine use as an antimicrobial Ozone s short half-life makes a residual algaecide necessary

Ozone for Pools and Spas The majority of US residential spas are equipped with ozone Less than 1% of US residential swimming pools use Ozone Historical disappointment of low production UV Ozone Affordable CD Ozone still requires the addition of a residual algaecide A Chlorine Free Ozone system properly sized for the volume of water in a swimming pool, is not economically feasible for the average pool owner (too expensive) With recent improvement in Ozone technology (affordable CD systems) and the advent of a combination salt/ozone system, residential swimming pool owners can now have the best of both technologies

Salt Chlorine A Brief History Discovered in 1774, the origin of all Chlorine is Salt In-line Salt Chlorine Generation Systems for pools have been in use for 25+ years In-line Salt Chlorine Generation Systems have become very popular in the US over the last five ten years In-line Salt Chlorine Generation Systems are often referred to as Soft Water Sanitation Systems In-line Salt Chlorine Generation Systems offer many advantages over traditional chlorine

Salt Chlorine Advantages Automatic operation Continuous oxidation of microorganisms in the water Oxidation in moderation no highs and lows No need for shocking the pool Water feels soft and silky No chlorine chemicals to buy, store or handle Once salt is added to the pool it is constantly recycled into chlorine

Salt Water Advantages Ancient Egyptians, Greeks and Romans used salt extensively as a remedy for skin disorders, diseases of the skin and to sooth eyes and nasal membranes Twentieth Century medicine discovered salt in the form of Saline Solution has the same fluid quality as blood plasma and is currently in use today as intravenous infusions Human life could not exist without salt; basic physiological functions depend on the balance between salts and liquids in the body Blood, sweat and tears all contain salt; eyes and skin are protected from infectious bacteria by the anti-bacterial effect of salt

Salt Water Advantages continued Swimming in a Salt Water pool is comforting and pleasant Salt levels in the pool water are ~3,500 PPM (human tears are ~6,000 PPM) and normally non-detectable by human taste buds In comparison, normal household softened water is ~350 PPM and the average ocean water is ~35,000 PPM Skin feels soft and silky after swimming in a Salt Water pool Salt water (3,500 PPM) is non-corrosive to equipment Salt water (3,500 PPM) is gentle to pool surfaces

Ozone System Sizing U.S. Ozone Systems are sized according to the pool water volume and bather load; always assuming 24 hour operation For optimum water quality, use the following ozone sizing formulas (applied ozone dose 1.6 PPM/Minimum 0.06 PPM 60 min.) Total gallons X 1.6 X 0.227 / 120 = Grams/hr O 3 Spa (94-104 F) Total gallons X 1.6 X 0.227 / 240 = Grams/hr O 3 Wading Pool (80-88 F) Total gallons X 1.6 X 0.227 / 720 = Grams/hr O 3 Therapy Pool (86-94 F) Total gallons X 1.6 X 0.227 / 1440 = Grams/hr O 3 Lap/Main Pool (78-85 F) Example Pool 125,000 Gallon Main Pool 125,000 X 1.6 X 0.227 / 1440 = 31.5 = CD-45 Other situations may need to be taken into consideration when sizing ozone for individual pools; DEL Ozone can assist 17

Ozone/Br & Cl Compatibility Ozone/Bromine (Br) Ozone converts spent Bromine (Sodium Bromide) back to useful Bromine while eliminating Bromamines This Process reduces Ozone Ozone/Chlorine (Cl) Ozone converts Chlorine to Chloride Ion while eliminating Chloramines and its offgas This Process reduces Chlorine Ozone provides the main oxidation and disinfection in the pool while the residual halogen (Chlorine or Bromine) provides a chemical residual Proper installation of an Ozone system suggests distancing the ozone feed location from the halogen feed location in an effort not to reduce either of the sanitizing capabilities The Ozone is installed first with a contact/degas vessel; or on a separate return line Ideal Chlorine level is 0.3 1.0 PPM; Over-sizing residual Cl level may result in higher chlorine losses due to reaction with Ozone (increased probability of contact) Ideal Bromine level is 1.0 2.0 PPM; Over-sizing the residual Br level may result in reduced Ozone oxidation effectiveness in the pool 24

Ozone vs. UV Sterilizers Both Ozone and UV provide very effective anti-microbial action as documented by NSF Standard 50, Annex H Ozone Destruction of Chloramines Ozone breaks down Chloramines by oxidation in two ways By breaking down the N-Cl bonds of the Chloramine molecules through oxidation by ozone (this process occurs at the point of ozone injection and continues the oxidation process as it passes at low levels into the pool) Ozone also forms hydroxyl radicals, adding to the Chloramine oxidation process Ozone reduction of Chloramines is known to reach zero UV Destruction of Chloramines UV can break down Chloramines in two ways By breaking the N-Cl bonds of the Chloramine molecules with UV light energy (this process occurs in the UV chamber only) By forming small numbers of hydroxyl radicals with UV light energy, which oxidize Chloramines (this process occurs within nanoseconds, effectively occurring only in, or very near the UV chamber) UV reduction of Chloramines has been documented to never reach zero 25
