In Australia, guidance has been developed for water utilities to help them understand and control the impact of NOM. Yet, increased NOM concentrations trigger the need to increase the coagulant dose to achieve neutrally-charged floc particles; otherwise, suboptimal coagulation conditions exist and a loss in pathogen log removal can occur.

MF and UF are referred to as low-pressure membranes and are used for particle/pathogen removal. (1999). COD: because COD measures oxidizable organic matter, a highly reactive source with 2 mg/L TOC and a less reactive source with 4 mg/L TOC can have comparable COD concentrations (Stoddart and Gagnon, 2014; Dabrowska, 2016).

Multiple factors affect the biostability of distributed water: type and concentration of organic and inorganic nutrients, type and concentration of residual disinfectant, biofilms and sediments, and distribution system conditions (e.g., disinfectant residual decay, water temperature, residence time, hydraulic conditions, pipe material and diameter, pH, corrosion rate) (LeChevallier et al., 2015a; Prest et al., 2016). Water Research Foundation, Denver, Colorado. Four types of pressure-driven membranes are currently used in drinking water treatment: microfiltration (MF), ultrafiltration (UF), nanofiltration (NF) and reverse osmosis (RO).
