How does the SBR process work?
The sequencing batch reactor (SBR) is a fill-and- draw activated sludge system for wastewater treatment. In this system, wastewater is added to a single “batch” reactor, treated to remove undesirable components, and then discharged.
What is the correct order of phases in a SBR operation cycle?
The operation of an SBR is based on a fill-and-draw principle, which consists of five steps—fill, react, settle, decant, and idle. These steps can be altered for different operational applications. During the fill phase, the basin receives influent wastewater.
What are the 5 wastewater treatment steps?
The Wastewater Treatment Process
- Stage One — Bar Screening.
- Stage Two — Screening.
- Stage Three — Primary Clarifier.
- Stage Four — Aeration.
- Stage Five — Secondary Clarifier.
- Stage Six — Chlorination (Disinfection)
- Stage Seven — Water Analysis & Testing.
- Stage Eight — Effluent Disposal.
What are the 3 steps to wastewater treatment?
The three stages of wastewater treatment are known as primary, secondary and tertiary. Each stage purifies water to a higher level. In some applications, only one or two stages are necessary. The level of treatment necessary depends on the water’s intended use case, and what environment it will be discharged into.
How does ETP work?
The principle of operation of ETP is Physico-Chemical treatment followed by Polishing Treatments like –Sand Filtration, Activated Charcoal treatment (Adsorption), Ozonisation (Chemical Oxidation), Ultra Filtration (UF), Reverse Osmosis (RO) and evaporation (If required). Features : Semi-automatic Operation.
What is COD and BOD in ETP water?
The biochemical oxygen demand (BOD) represents the amount of dissolved oxygen (DO) consumed by biological organisms when they decompose organic matter in water. The chemical oxygen demand (COD) is the amount of oxygen consumed when the water sample is chemically oxidised.
Is SBR soluble in water?
PH: 4.5-6.5. Viscosity: (NJD-5S,25 degrees Centigrade) 20-250 mPa. Storage temperature: 0-38 ℃ Solubility: Water soluble.
