With EPAeration you're buying the best:
- The best ozone generators
- The best air-diffusion tubing
- The best compressors available
And yet the EPAeration difference is more than just equipment - it's the experience we've gained in aerating lakes, ponds, and water features of all descriptions, in all sorts of climates. When we recommend a solution for your water problems, you can be sure that you're getting more than a one-size-fits-all type of answer - you're getting the EPAeration difference.
EPAeration utilizes bottom laid, fine bubble aeration:
- Increasing dissolved oxygen levels throughout the water column
- Eliminating thermal stratification
Because our lake and pond systems use standard household current (120 VAC, 15-amp circuit), and because we pump air, not water, our customers realize significant savings in installation, operation and maintenance costs.
Our current, modular systems are the result of more than 10 years of development, and 20 years of ozone generation and lake and pond aeration experience. The modular nature of the system allows us to recommend the most effective - and cost effective - solutions for your water problems
EPAeration utilizes proprietary air-diffusion tubing in its lake and pond ozonation/aeration
system modules. In use for more than 35 years in the wastewater treatment
industry, this keel-weighted, bottom-laid tubing features the highest documented
oxygen transfer rates in the business. The keel weighting ensures that the tubing
lies on the bottom, at the sludge layer, with the air release slits always upright.
Available with air release slits cut on 6-inch centers, 3-inch centers,
and 1 ½-inch centers, the tubing can also be manufactured in "triple cut", or
three air release slits at each position, for more demanding jobs. The air release
slits are precisely cut to produce a calculated bubble size and rate of rise
(no more than .8 ft. per second). No other air diffusion system, including competitive
tubing, has the proven performance of that used by EPAeration, which is why it was
selected originally more than 10 years ago, and why it is still in use today.
The precise cut, and material memory ensure that the slits only open with 2 psi or more of pressure, and close immediately on shut-down. This ensures that minimal amounts of water and/or dirt can enter the tubing, minimizing cleaning and maintenance.
Made of low-density polyethylene copolymer with 2% carbon black for ultraviolet stabilization, the tubing has an interior diameter of .5". The tubing meets r exceeds Federal Specification L-P-3906, REA PE-200, and ASTM D1248.
Although EPAeration system modules generally utilize tubing laid in a straight line on the bottom at the deepest part of the water feature, the tubing is also available on custom-made diffusion disks for deep holes or unusual pond configurations.
Ozonation...
- Dissolves into water 13 times faster than O2
- Kills viruses, bacteria, molds, spores, and cysts up to 3000 times faster than chlorine
- Keeps the inside of bottom-laid tubing clean and maintenance free
- Oxidizes organic nutrients, chlorohydrocarbons
- Precipitates iron, manganese, and heavy metals from water
- Produces increased water clarity
- Has been shown to affect soil absorption rates of salts and other compounds
EPAeration systems generate ozone in two ways, each of which mimics the way ozone is produced in nature.
Generally, our lake and pond systems utilize ultraviolet light to produce the small amounts of ozone
appropriate to that application. In our recirculation, closed-loop water treatment systems, we utilize
corona-discharge (high-voltage electricity) generators, which produce larger quantities of ozone
which are usually injected directly into the recirculation or pump system. The availability of
both types of ozone generators and the modular nature of our systems allows us to customize systems
recommendations to solve the myriad of specific problems possible in a wide range of applications.
The use of ozone in most lake and pond applications is not intended to "kill algae" or sterilize the water
feature. Instead, our lake and pond systems are designed to:
- Address the Biochemical Oxygen Demand (BOD) of the water with Aeration
- Use ozone to increase oxygenation in the water
- Oxidize hydrogen sulfide
- Precipitate out certain metals and suspend solids
- Keep the aeration tubing clean and maintenance-free
Of course, if circumstances demand larger quantities of ozone, we have the capabilities of meeting such demand.
Generally speaking, EPAeration's aeration/ozonation systems are compatible with other non-chemical strategies, such as the use of bio-augmentation systems. While it is true that ozone will kill bacteria, (even beneficial ones) on contact, only a small number of sludge-eating bacteria, for example, will come into contact with the ozone at the point of bubble release. Ozone will usually be consumed by other substances in the water, and never reach the surface to be recirculated.
Ozone's primary byproduct is oxygen. It is unstable, and does not produce a long-term residual. It is an important adjunct component in out lake and pond aeration systems. Ozone is an appropriate primary treatment for closed-loop and/or recirculation systems.
