DBP Formation Potential - Real Tech Water
DBP Formation Potential - Real Tech Water DBP AND FORMATION POTENTIAL MONITORING Chemical disinfection can cause the formation of harmful byproducts when disinfectants like chlorine react with naturally occurring compounds such as organic matter in water.
Evaluation of disinfection by-products (DBPs) formation
has a low specic TCM formation potential of 0.778 mmol/mmol C and a trichloronitromethane (TCNM) formation potential of 0.0725 mmol/mmol C, leading to a TCM and TCNM formation potential ratio of 10.7. We found that substrate utilization of anammox did not enhance DBP yields, and the DBP formation potential decreased after 10 hour starvation.
Evaluation of disinfection by-products (DBPs) formation
2.4 DBP formation potential (DBPFP) tests DBP formation potential tests were conducted to evaluate the maximum DBP formation ability of the water samples. Free chlorine was used as the disinfectant in DBPFP tests. The oxidation of ammonium in the effluents by chlorine will generate chloramine, which would affect DBPs formation.
Predicting disinfection by-product formation potential in water
Water samples from W/WWTPs across the USA were collected and DBP formation potentials (DBPFPs) in the presence of free chlorine and chloramine were obtained for trihalomethane (THM), haloacetic acid (HAA), haloacetonitrile (HAN), and N-nitrosodimethylamine (NDMA).

- What is DBP formation potential (dbpfp)?
- DBP formation potential (DBPFPs) experiments are designed to maximize reactions between the precursors and disinfectant (e.g., Krasner et al., 2008). With knowledge of trends between precursors and DBPFP, unit processes capable of reducing more important precursors can be employed to reduce overall DBP levels in treated water.
- What are DBP precursors?
- DBP precursors are defined as a mixture of organic and inorganic compounds that can form DBPs under some level of disinfection. DBP formation potential (DBPFPs) experiments are designed to maximize reactions between the precursors and disinfectant (e.g., Krasner et al., 2008).
- What are the external factors in DBP estimation models?
- Unlike other DBP estimation models, the models in this study did not consider the external factors (e.g., disinfection dosage, temperature, dosage, etc) in order to streamline a better understanding of the DBP precursors’ origin, constituent, reactivity, and adjusting factor.
- Can power function models predict dbpfp levels in potable water sources?
- Conclusions Power function models based upon DOC, UVA and bromide were able to predict DBPFP levels across several classes of C-DBPs and N-DBPs in both potable water sources and wastewater effluents.
- What is the formula for dbpfp?
- Equation (1B): DBPFP = a × DOC b × UVA 254 c × ( Br + 1) d × ( N ∗ + 1) e. Analytical variances of various types of waters. Note: The units of DOC and bromide are mg/L; UVA is 1/cm; AV is %; SE and DBPFP concentrations are μg/L except NDMAFP (ng/L) for weight-based models; the units are μM/L except NDMA (nM/L) for molar-based models. 4. Conclusions
- What is DBP formation in water reuse treatment?
- Policies and ethics DBP formation in water reuse treatment may follow trends that do not necessarily follow what is commonly observed in drinking water treatment. This is because organic precursors in treated wastewater can exhibit different characteristics than organics found in...
