There are three chemicals normally applied to destroy chlorine in water systems. These are: 1) Tramfloc® 905 Dechlorination Solution 2) Tramfloc® Dechlorination Tablets 3) Tramfloc® Ascorbic Granules. The following text describes the three different reagents.

TRAMFLOC DECHLORINATION SOLUTION

It is sometimes desirable to apply Tramfloc® 905, a dechlorinating solution, which lends itself effectively to continuous flows of chlorinated water where regulations prohibit the discharge of any chlorine or sulfite residual. Please consult Tramfloc, Inc. for Tramfloc® 905 dosage rates and application techniques. We frequently use a chemical metering pump to administer Tramfloc® 905. The application of our dechlorination liquid reagent often lends itself to a lower maintenance requirement. This can be very helpful to dechlorination applications. Tramfloc® 905 is NSF 60 compliant, which means that the reagent can be fed to drinking water without deleterious effects. Tramfloc® 905 is a very benign dechlorinating solution. This reagent can be delivered to the chlorinated water stream by a simple chemical metering pump. We can provide such equipment or recommend a local supplier for your project. We use a stoichiometric dosage of 5 ppm solution/1 ppm Cl2. Tramfloc® 905 is the simplest and easiest to apply dechlorination reagent and is the product of choice in small and temporary dechlorination projects. Please the product data for this formulation. This dechlorination approach requires the lowest labor input of the three reagents. This is very important to project contractors and system owners.

TRAMFLOC DECHLORINATION GRANULES

In certain applications it may be desirable to use an entirely different chemical reagent to destroy the chlorine, this reagent is ascorbic acid, commonly known as, Vitamin C. Ascorbic acid is applied as a granular material to create a solution which is fed to a chlorinated stream to completely destroy the chlorine. In certain regulatory environments ascorbic acid is the preferred dechlorinating agent because our material is so benign and is actually beneficial to aquatic plants and animals. The end-user would be wise to consult the regulators in his locality to determine which of our reagents would be the most acceptable in a specific dechlorination application. We use a stoichiometric dosage of 4 ppm granules/1 ppm Cl2. For feeding techniques and dosage information, please contact Tramfloc, Inc.

For additional information about these three dechlorination reagents, please see our product data section on the home page and review both the Tramfloc MSDS and technical information documents. Please contact our technical department for recommendations for your specific application details, product dosage and project cost estimates. Regulators are increasingly requiring contractors to apply on ascorbic acid granules due to safety and environmental concerns about other chemical reagents, even if these other chemicals are known to be benign. While treatment costs with ascorbic acid tend to be higher than the our tablet or liquid costs, the regulators usually always give their unqualified preference and approval to this special “Vitamin C” reagent.

Please be sure to review the link about our “H2O Neutralizer Device” which is used to deliver the dechlorinating solution made from: liquid Tramfloc® 905, Dechlorination Tablets or Dechlorination Ascorbic Granules/Tablets. This device is used to accurately apply the selected dechlorinating solution at the optimum dosage rate to produce complete chlorine destruction with the lowest reagent usage to control your costs.

TRAMFLOC DECHLORINATION TABLETS

Tramfloc® Dechlorination Tablets are uniquely formulated to provide an efficient and cost effective way of reducing or removing free and combined chlorine from water systems. When used in an approved gravity flow tablet feeder, Tramfloc® Dechlorination Tablets provide a stable and controlled release of environmentally safe sodium sulfite, to insure the effective reduction of chlorine residual while maintaining overall effluent quality. Introduced after years of research and development, Tramfloc® Dechlorination Tablets contain a unique chemical formulation that protects effluent quality while neutralizing both free and combined chlorine. Research proves that higher concentrations of sodium sulfite can degrade beneficial dissolved oxygen levels, increase BOD5 and reduce overall effluent quality. The superior formulation of Tramfloc® Dechlorination Tablets provides consistent reduction or elimination of chlorine residual without significantly reducing dissolved oxygen. Packaged in 45 lb. DOT approved containers, Tramfloc® Dechlorination Tablets are a preferred alternative to costly and hazardous liquid, gas or mechanical dechlorination systems. If your treatment system requires dechlorination, please consider the advantages of Tramfloc® Dechlorination Tablets.

DECHLORINATION: TABLET PROPERTIES AND USAGE

When used as directed, Tramfloc® Dechlorination Tablets provide an environmentally safe dose of sodium sulfite capable of neutralizing free and combined chlorine present in water systems. Research shows that high concentrations of sodium sulfite will degrade beneficial dissolved oxygen in receiving environments, producing harmful effects on the ecosystem. Tramfloc® Tablets shall provide consistent reduction or elimination of residual chlorine without affecting water quality, dissolved oxygen or other discharge parameters. A unique combination of sustained release agents and sodium sulfite maintain a consistently uniform application rate regardless of flow, temperature or humidity. Tramfloc® Dechlorination Tablets generally lower chemical consumption and provide reliable reduction of chlorine residual in a more thorough, safe and economical manner than simple sodium sulfite. Therefore, the use of other tablets of similar composition probably will not produce optimum results.

DECHLORINATION: TABLET PRODUCT APPLICATION

Tramfloc® Dechlorination Tablets are effective in the reduction or elimination of residual chlorine without releasing excess quantities of sodium sulfite into the receiving environment. Tramfloc® Tablets weigh about 5 ounces or about 140 grams. The tablets are 2.625” in diameter and 0.812” thick. Tramfloc® Tablets are considered non-hazardous under U.S. Department of Transportation (DOT), U.S. Environmental Protection Agency, RCRA, CERCLA and Sara Title III listings.
The following is a list of some common applications where Tramfloc® Dechlorination reagents may be utilized: municipal wastewater treatment plants, municipal water treatment plants, septic tanks, sand filters, extended aeration plants, wastewater treatment lagoons, package wastewater treatment systems, spray irrigation systems, potable water filtration backwash, hydrant flushing, new pipeline dechlorination, water tank cleaning and water towers. We use a stoichiometric dosage of 3 ppm tablets/1 ppm Cl2. Tablet feeders are available or one may employ a rudimentary mesh bag or a perforated bucket to feed tablets. This feeding technique works very effectively in low flow, no electrical power, and little labor availability applications.

DECHLORINATION COEFFICIENT OF TREATMENT COST

Our chemists have developed an expression of cost, the coefficient of treatment cost, Ctc, to express the relationship of reagent cost to the performance of one of three treatment modalities. The Ctc has been assigned to each reagent to help the engineer to make decisions about the economics of each treatment modality. Once this factor has been considered, the engineer is better able to make an informed purchasing decision based on labor demands and capital equipment requirements, regulatory concerns, owner’s preferences and the all important chemical costs. The lower the coefficient, the lower the treatment cost is. This cost is one of the engineer’s consideration. For further details and specific cost calculations, please contact Tramfloc, Inc. at
