BREAKPOINT CHLORINATION AS AN ALTERNATE MEANS OF AMMONIA/NITROGEN REMOVAL AT A WATER RECLAMATION PLANT by Matthew A. Brooks Adil N.

Breakpoint Chlorination as an Alternate means for Ammoia-Nitrogen removal at a Water Reclamation Plant study was to define optimum breakpoint pilot plant operating conditions which could then be applied to the design of a full scale breakpoint facility and serve as an emergency backup to biological nitrification.

Actual and calculated total chlorine demand during, (a) breakpoint chlorination (breakpoint chlorination was carried out by spiking total chlorine of – mg Cl 2 L −1) and, (b) re-chloramination (re-chloramination was carried out by maintaining initial total chlorine residuals of mg Cl 2 L −1 in the breakpoint chlorinated samples).Cited by: 3.

After chlorination process, the relevance ratios of effluent standard of the coliform group in BOD removal type Johkasou and Nitrogen removal type Johkasou were % and %, respectively.

Breakpoint chlorination experiments were conducted using raw and partially treated waters from City A and City B, in order to evaluate the influence of Cl 2: total NH 3-N ratios on NDMA the purposes of this paper, total NH 3-N refers to the sum of ammonia added during chloramination experiments (1 mg/L) plus ammonia already present in water ().Cited by:   Wastewater Treatment Technologies for the Removal of Phosphorous Controlling phosphorous discharged from municipal and industrial wastewater treatment plants is a key factor in preventing eutrophication of surface waters.

Phosphorous is one of the major nutrients contributing in the increased eutrophication of lakes and natural waters.

Chemical Precipitation: In Chemical Precipitation, supernatant of an aerobically digested activated sludge was used as the substrate with the aim of phos-phorous and nitrogen removal.

The goal of disinfection of public water supplies is the elimination of the pathogens that are responsible for waterborne diseases. The transmission of diseases such as typhoid and paratyphoid fevers, cholera, salmonellosis, and shigellosis can be controlled with treatments that substantially reduce the total number of viable microorganisms in the water.

All of the biological processes for nitrogen removal include an aerobic zone in which biological nitrification occurs. Gas stripping for removal of ammonia or breakpoint chlorination as the primary means for nitrogen removal is not commonly employed in wastewater reclamation applications in the United States.

The National Academies. Nutrient Removal covers environmental and regulatory issues and provides an integrated approach for combined nitrogen and phosphorus removal, including details on ammonia and dewatering liquors treatment. Natural treatment systems are also discussed in this definitive guide.

A novel system integrating Johannesburg (JHB) and sulfur autotrophic denitrification (SAD) process was proposed to enhance nitrogen removal in treating low COD/TN ratio (COD mg/L, TN 29 mg/L on average) municipal wastewater at low temperature ( ± °C).

When using chloramines, two decisions must be made as to the specifics of application • Chlorine/nitrogen ratio • Order of addition. The chlorine to nitrogen ratio is very important as it determines the equilibrium.

This report assesses the health effects and safety of using reclaimed water as a sole source or as a component of the potable water supply. The report was prepared by the Committee to Evaluate the Viability of Augmenting Potable Water Supplies With Reclaimed Water, which was appointed by the National Research Council (NRC) to evaluate issues associated with potable reuse of municipal.

Zone III: Chloramines are broken down and converted to nitrogen gas which leaves the system (Breakpoint). Zone IV: Free residual. Therefore, it is very important to understand the amount and type of chlorine that must be added to overcome the difficulties in the strength of the disinfectant which results from the wastewater's characteristics.

Topics that are covered include: the organisms responsible for nitrification and denitrification, stoichiometry, variables that impact performance, the different types of unit processes (fixed films and activated sludge) that can be used for nitrogen removal, ion exchange, and breakpoint chlorination.

During full-scale runs it was possible to reduce ammonia by 50 to 70 % for most of the time. Diurnal and seasonal fluctuations, however, still caused appreciable chlorination control problems which could be alleviated to some extent by the introduction of a quality equalisation basin9.

Simultaneous nitrogen removal and formate depletion was achieved at the molar ratio of formate to nitrate of 3. The outcome of this study opens a new avenue to abate excess nitrogen in aquatic environment and provides insightful guidance on designing efficient treatment process for nitrogen removal.

The UV/breakpoint chlorination process. Nitrogen removal from wastewater through partial nitrification/Anammox was investigated. The objectives of the research were divided to three distinctive and related areas: Partial Nitrification (PN) process, Anammox reaction and green house gases emission from partial nitrification and Anammox reactor.

In the PN process, research objectives were to determine: 1) the effect Dissolved Oxygen Author: Fatemeh Kosari. Full text of "Selected water resources abstracts" See other formats.

All breakpoint testing utilized a 50 to. The membrane filters provide enhanced removal of microbial pathogens with the extent of removal depending on pore size.

This removal is enhanced by formation of a cake layer on the surface of membranes during operation, which effectively reduces pore sizes and increases removal of small particles such as viruses (Branch & Le-Clech, ).

Total nitrogen measured in the final, disinfected reclaimed water before groundwater recharge must not exceed a monthly average of 10 mg/L N or a sample maximum of 15 mg/L N." Although there are biological means to remove nitrogen, the rule should permit other means to achieve the same water quality results (e.g.
