Evaluation of disinfection by-products (DBPs) formation potential
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.
Challenges in Reusing Produced Water - Society of Petroleum Engineers
The DBP formation potential of treated produced water has not been investigated. Although the total organic carbon concentration of RO-treated produced water is low, the presence of iodide and bromide can potentially form DBPs that are much more toxic than chlorinated DBPs (Woo et al. 2002).
Predicting disinfection by-product formation potential in water
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).
Haloacetic Acids Formation Potential of Tropical Peat Water
Tropical peat water dissolved organic matter (DOM) fractions spectral parameters correlate with the formation of carcinogenic disinfection by-products (DBPs), haloacetic acids (HAAs). Peat water DOM has been fractionated using Superlite DAX-8, Amberlite XAD-4, and Amberlite IRA-958 resins to separate hydrophobic acid (HPOA), transphilic (TPH), hydrophilic-charged (HPIC), and hydrophilic
Management Strategies for Minimising DBPs Formation in
RBF was able to reduce 35–67% of dissolved DOC and THM- formation potential (FP), and HAA-FP reductions ranged from 57 to 73% and from 50 to 78%, respectively, in three full-scale RBF sites [ 45 ]. Removal of the DBP precursors is commonly used approach in order to reduce overall DBP formation.
- 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).
- Can disinfection byproduct (DBP) formation potential be evaluated?
- Disinfection Byproduct (DBP) Formation Potential. Two approaches were described in the selected articles to evaluate DBP formation, which are fully reported in SI, Extracted Data.
- What is the DBP formation potential of BFA?
- Both BFA stock solution and tap water were diluted until TOC was 1 mg/L. DBP formation potential of individual components, including urea, creatinine, uric acid, citric acid, l-histidine, hippuric acid and ammonium chloride, in BFA was also investigated.
- What is a good mw for DBP precursors?
- For all groups of DBPs, the correlated formulae generally had MW of <450 Da (Fig. 4) consistent with prior reporting that low MW compounds tend to evade coagulation (Bond et al., 2010). While THM and HAA precursors were relatively broadly distributed below 400 m / z, HAM and HAN precursors fell into a tighter range of ∼300 to 400 m / z (Fig. 4).
- Which aliphatic compounds are the primary precursors of DBPs?
- Low MW (<450 Da) aliphatic compounds, and highly unsaturated and phenolic compounds were the primary precursors of THMs, HANs, and HAMs, and the formation potentials (FPs) of these groups of DBPs were correlated with multiple individual molecular formulae. HAA FPs were correlated with low MW, highly unsaturated and phenolic compounds.
