100 max 75 75 WATER TREATMENT PLANT DESIGN2 Design Criteria This video is containing calculation of flash mixer and flocculator. The chemical water mixture is vigorously agitated within the chamber resulting in almost instantaneous mixing. Coagulation is an essential component in water treatment operations. Index of information discussing the topics of mixing coagulants and the design of Flash and/or Rapid Mixers in series with primary and secondary flocculation chambers of waste or water treatment plants. Flash Mixing Chamber A Flash Mixing Chamber is a chamber in which coagulants and other chemicals are blended with water or wastewater prior to flocculation. Conventional plants separate coagulation (or rapid-mix) stage from flocculation (or slow-mix) stage. The … A rapid mix basin employing alum was designed to treatment processes are covered by full and interlinked design examples which are built up throughout the series and the books, from the determination of the waste-water characteristics, the impact of the discharge into rivers and lakes, the design of several wastewater treatment processes and the design of the sludge treatment and disposal units. The population of Gatorsville is 150,000 persons who require a maximum of 120 gallons/person/day of potable water. 2.4 MIXERS 2.4.1 Equalization Unit Mixer 2.4.2 Precipitation Unit Mixer 2.4.3 Coagulation Unit Mixer 2.4.4 Flocculation Unit Mixer 2.4.5 Effluent Holding Unit Mixer ... includes the P/C/F equipment required for a water treatment plant to remove dissolved metals. Plants designed for direct filtration route water directly from flocculation to filtration. In conventional water treatment plants (WTPs), rapid mixing is typically conducted in a basin with a mechanical mixer or by hydraulic jump at a fixed G value less than 1000 s −1. The merits and drawbacks of other approaches to Evaluation and optimization of the coagulation/rapid mixing step of the water treatment process includes a variety of aspects. Information includes engineering and material specification, mixer sizing parameters based upon flash chamber geometry, maximum throughput or flow rate(MGD) and other useful information. These systems typically have a higher raw-water quality. The city of Gatorsville, Florida has decided to construct a surface water treatment plant that will remove arsenic from the groundwater and provide potable water to the city. To ensure the quality of the treated water, operators normally apply high concentration of coagulant to remove turbidity through sweep flocculation. Higher percentage of coagulant utilization leads to better treated water quality.

Coagulation and Rapid Mixing Coagulation is the process by which particles become destabilized and begin to clump together. Equations are developed to predict the volume of bubbles that potentially form during treatment processes, and a new device to physically measure the gas formation potential of a water is introduced. Flocculation Tapered flocculation Less energy input, better floc formation. ♦ Flash Mixing ♦ Jar Testing ♦ Turbidity PREPARATION TIME: LESSON TIME: Activity Kit 4 Water Treatment Plant 2 RAINWATER TO TAP WATER- THE PROCESS The process from rainwater to tap water is more complex than you might imagine.
