Chemical oxidation is used in water treatment to aid in the removal of inorganic con-taminants such as iron (Fe 2+), manganese (Mn ), and arsenic (As3+) to improve re-movals of particles by coagulation or to destroy taste- and odor-causing compounds. Oxidation can also be used prior to coagulation, filtration, adsorption, or sedimenta-

Coagulation filtration is a process that introduces a coagulant, typically an iron or aluminum salt, to pretreat water contaminated with arsenic , iron, manganese , and/or sulfides . The process allows for significantly higher flow rates per square foot of media, creates less backwash water than other conventional treatment approaches, and has a smaller footprint which allows for lower operating and capital costs. Advanced oxidation processes (AOPs) utilizing powerful hydroxyl or sulfate radicals as a major oxidizing agent were first proposed in the 1980s for potable water treatment. Later, AOPs were broadly applied for treatment of different types of wastewaters because the strong oxidants can readily degrade recalcitrant organic pollutants and remove certain inorganic pollutants in wastewater. • Fed as part of Advanced Oxidation Process –UV + H2O2 –3-5 mg/l dose • Try to carry 2 mg/l onto filter –UFRV regularly > 50,000 –Minimize zooplankton regrowth on top of filter –Control extracellular polymeric substances (EPS) –Improve IFE turbidities and particle counts. Electrocoagulation is a technique used for wastewater treatment, wash water treatment, industrially processed water, and medical treatment. Electrocoagulation has become a rapidly growing area of wastewater treatment due to its ability to remove contaminants that are generally more difficult to remove by filtration or chemical treatment systems, such as emulsified oil, total petroleum hydrocarbons, refractory organics, suspended solids, and heavy metals.

The effluent of advanced oxidation was directed to an aerated membrane filtration . The characteristics of the final effluent are shown in Table 3 . The achieved removal rate of the COD, BOD, TSS, oil and grease, S 2− , TKN and TP was 97.2, 97.0, 93.0, 87.4, 96.2, 75.0, and 40.8% respectively ( Table 3 ).

Even after coagulation and flocculation, sedimentation does not remove enough (They can also be employed in advanced wastewater treatme Design considerations for coagulation and flocculation processes include: the For direct filtration, the detention time required is usually less, typically 15 minutes. Advanced oxidation processes (Section 5.14.4 Advanced Oxidatio Advanced Oxidation-Coagulation-Filtration (AOCF) has been investigated for producing drinking water with less than 1 μg L-1 of As through a series of bench advanced oxidation processes and electrocoagulation, Linnaeus University The two columns of the sorption/filtration unit were made from polyvinyl. chloride Advanced Oxidation Treatment of Recalcitrant Wastewater from a Electrocoagulation coupled to activated carbon sorption/filtration for treatment of cleaning wastewater treatment resulting in a chemical-free, low energy technology.
