ODOR CONTROL. WaterSolve odor control products are a low cost, non sensitizing, non toxic, material with no VOC’s. These products can be used in a variety of applications such as Geotextile dewatering, eliminating sludge odors in wastewater treatment.

Oct 15, 2018 · Ferric salts are another important class of inorganic coagulants. Given their low cost, fast settling velocity of ferric flocs, and lower toxicity, wider pH range of applications, better effect in low temperatures compared to PAC (Bratby, 2016; Lee et al., 2014), ferric salts are also favored in many wastewater treatment plants (Bień and Bień, 2014; Niu et al., 2013).
