OASE Products: Bitron C UV Clarifiers

Bitron

The New Power For Clean Water

The newest revolution among UV-Clarifiers with the highest level of efficiency thanks to an even longer water dwell time (time in which the water is in contact with UV Light). Irradiation times are regulated automatically and thus energy costs are reduced by as much as 50%! The clever cleaning automation ensures permanent, intensive UV irradiation from 120 – 240 W.

Works with perfected efficiency«

The Bitron C becomes one of the most efficient UVC reactors in controlling algae and bacteria, through a combination of strong features, such as irradiation capacity, water dwell time and thorough mixing. All these features together make the powerful innovation perfect.

 

Patented cleaning rotor:

Via the water flow the cleaning rotor is continuously guided around the quartz glass tube and thus prevents debris from settling.

Easy Maintenance:

By pressing our locking button and twisting the unit, we have full access to easily change the UV. No difficult task and can done in a matter of minutes.

Incredible UV Power

The Bitron is our most powerful UV Clarifier currently offered. from 36W to an impressive 110W we have the UV Clarifier for any pond size. Make an investment in clear water and install a Bitron C UV Clarifier in your pond system today.

OASE Bitron 36C UV-C Pond Clarifier

Item#:  56935

The UV-C technology in Bitron C clarifiers helps ensure consistently clear and healthy water by flocculating (“clumping”) microscopic green algae that are the main contributors to green and unsightly pond water.

Aqua Ultraviolet UV Series Test

Aqua Ultraviolet UV Series Test By Manufacturer

Real Science . Not Science Fiction

At Aqua Ultraviolet as with any successful business, competitors will attempt to mimic your products. While the old adage states “imitation is the sincerest form of flattery,” some of our competitors marketing claims have unfairly maligned our products and distorted the facts.

If you follow our competitor’s information then our units shouldn’t work at all, we wouldn’t even be in business, and yet we are number #1 year after year. Aqua Ultraviolet designs, tests and brings to market innovative products each year while our competitors criticize, then copy us.

We sympathize with the competition, how can they possibly market against the best? By making misleading claims about lamp performance, ultraviolet exposure, and chamber design, they are basically creating propaganda.

Let us give you the facts.

Simply put, Aqua Ultraviolet sterilizers will clear your water in 3 to 5 days, sometimes overnight and keep it that way. We don’t require you to slow your flow rates down to accommodate dirty green water; we eliminate it.

Aqua Ultraviolet has been in business for over 27 years, we have designed units for many industries including drinking water purification, food preparation and manufacturing applications. Remember that in many of these industries the specifications are very stringent. Some of our competitors, have even sought us out to design and produce UV’s for them.

Why do our products trump the competition? Here are a few reasons:

• Our UV sterilizers are easier to use than the competitions, and they offer a longer lamp life – 14 months over about 9 months for the competition.
• Our products are generational. We keep parts and supplies for all models, and the parts will always work within the generations.
• Our high-powered units are compact. The competition’s are larger and need more space for installation.
• Our lamps are rated at the end of life, not at the beginning.
• Our initial testing is performed in-house and field tested, and then results are verified by independently laboratories. Therefore, the testing is fair and unbiased.
• Our products come with Technical support people to help with installation questions and other inquiries.
• Our technical support staff has even assisted consumers with competitors products.
• A live person is available Monday through Friday 8:00 am to 4:30 pm.

Ultima II Filter Series Test

 

Filtration Test By Manufacturer

Ultima II Filter Outperforms Bead Filters – Independently Verified!!!

The Ultima II is proving to be the best, with the results of an independent certified testing laboratory. Gillespie Laboratories is an aquatic toxicity-testing laboratory that also cultures various freshwater, marine fish and crustaceans. The test is being performed by an independent laboratory to set aside the misinformation, misunderstanding and unsubstantiated claims that prevail. We noticed that some claims are being made without testing, or better yet the tests are performed by people who have no knowledge of how to perform an educated test. We also noticed that all published tests are done by people who profit from the sale of their filters. The questions we asked “How accurate are the tests? What was left out? Did they tell the public everything? Or did they just lie?” Aqua Ultraviolet is committed to truth in advertising. Remember, while we are paying for the test, Gillespie Laboratories is certified and the information cannot be altered or changed. Should our filter perform less, we will be fair in publishing the results. Just a note, the Ultima has been field and laboratory tested by Aqua Ultraviolet for years. The Ultima II is taking names and setting new standards. Look out beads!

Equipment and System Setup

Each system (four) consists of 500-gallon circular tanks outside, containing 450 gallons of de-chlorinated laboratory water. Piping is 1.5 inch pvc. A standpipe with 100 half-inch holes sends culture water to pumps and filters. Each system uses a 1/3 horsepower Performance Pro Artesian pump provided by Performance Pro. Each system is stocked with 300 Koi provided by Purdin Koi Farms, which are approximately 6.5 cm (2.5 inches) in length. During the eight weeks all filters were backwashed weekly at approximately the same time, the same volume of water is removed from each system during backwashing. The Koi in each system are fed 4 grams of Pond Flakes twice daily. The filters that are being tested are Hydrabead#36™, BBF-1B™, Aquadyne1.1™, and the Ultima 2000™. The Hydrabead is difficult to setup. BBF is difficult to setup. Aquadyne is easy to setup, but the beads had to be installed . The Ultima 2000 was easy to setup, and the only filter to come with media inside the housing.

Performance

At week nine the Ultima was out front!

Ultima 2000
First system to attain nitrification. Very good consistent flow. Very good solids removal. Operation performance very consistent. Filtration system seems to require the least amount of maintenance.

Aquadyne 1.1
Second system to reach nitrification. Efficient solids removed. A significant decrease of flow starting week #6. Flow was not increased by backwashing. A decrease in pH and flow could indicate caking of filter beads by organics. The end of week #8 a greater decrease in flow and water becoming a dark brown color.

Hydrabead #36
Did not attain full nitrification until week #7. Water in system muddy-brown color. Solids removal is not as good as other systems. A reduction of pH along with increasing muddy colored water could indicate caking of filter beads by organic materials.

BBF-1B
Very good water flow. Very difficult to backwash. Instructions call for daily backwashing. After backwashing, a significant amount of “dirty water” flows back into culture tank. This clouds the water for a day. Due to time constraints, laboratory discontinued daily backwashing after Week #2. This has not caused any detrimental effects to fish.

Solid removal for filters, Lower numbers indicate fewer solids in water.
Ultima 2000          Aquadyne 1.1         Hydrabead#36        BBF-1B
.066                           .122                           .688                      .113

In fairness to bead filters on the market we could not test everyone’s. Since all are based on plastic beads and similar in filtration concepts, we would hypothesize that these other bead filters on the market would test the same as the ones chosen in our experiment. We have tried blowers and air compressors, which have proven to just be a band-aid to conceal a problem. If any of our dealers have any suggestions or would like to see us test different filters, of course give us a call.
