A cross-flow horizontal shaft paddle wheel flocculation basin is to be designed for a flow of 25000m3d a mean velocity gradient of 267sec at 10C and a detention time of 45 minutes.
. Maximum Day Flow. Water is pumped from the reservoir into a basin about 8 deep 15 wide and 80 to 100 long. And 50 mgl for low concs.
Chemical application in combination with energy transferred into the water from the flocculators allows particles to build in size and be removed in subsequent processes. Small G and large t produce big but light flocs. The flocculation basin is to be divided into 3.
Design a horizontal flow baffled channel flocculatorfor a treatment plant of 10000m 3day capacity. Total number of treatment trains basins in parallel. Figure 34 Horizontal Paddle Flocculator Design An 2017 Bottom left.
Drag coefficient C 0. Amwell paddle wheel flocculators provide engineers and water treatment facilities with well designed well crafted flocculator systems engineered for long life and minimal maintenance. 4 Total number of compartments stages in series per train.
Alum coagulant was used for 70 test runs at 85 mgl for high kaolin concs. 4 Design flow rate. Paddle area A 0.
Vertical paddle wheel flocculators consist of a drive assembly containing a gear motor stainless steel drive stand shaft coupling shaft collar thrust bearing and drive shaft which connects. Flocculator mechanisms can be oriented horizontally or vertically depending upon drive location andor customer preferences. Horizontal flocculator drives can have a dry well requiring a wall penetration or a wet well arrangement.
MRIs Paddle Wheel Flocculator provides a unique advantage. PWS Publishing Company 1996. JMS Mega-FLOC Horizontal Paddle Wheel Flocculator is one of the most efficient flocculators to date.
Water density p 0. Flow to the flocculator was 30 or 40 lmin at temperatures of 15 20 or 28 oC for 4 flocculator bed slopes 1 in 40 48 60 and 120 and various arrangements of the baffle types shown in Fig2 as listed in Table 1. To remove these materials a method called flocculation is used.
Typical horizontal paddle wheel flocculator. Tapered flocculation is to be provided and the three compartments of equal depth in series are to be used. On each paddle wheel having a common horizontal shaft.
Paddles revolve around a horizontal shaft driven by a motor and reducer through a chain and sprocket arrangement. This enables a varied paddle configuration and achieves the use of a range of G-values which in turn advances the ability to control flocculation outcomes. The paddle size the number of paddles diameter of the paddle wheels on the various horizontal shafts the rotational speed of the various horizontal shafts 46 Ref.
Using robust components and a complete stainless steel design MRIs Vertical Paddle Wheel Flocculators will create optimal floc for years to come. This is a traditional flocculator design for water treatment appli-cations. Paddle Flocculators Amwell paddle wheel.
11 Tapered flocculation may be obtained by varying. The GT value should be from 50000 to 100000. JMS Mega-FLOC HPWF have been utilized in thousands o.
JMS Mega-FLOCS Paddle Wheel Flocculators are available for all of your flocculation needs. Power input is varied by changing the paddle tip speed while adding. Big and dense flocs are desirable - this can be obtained by.
Amwell flocculators are available in your choice of horizontal or vertical configurations for all water applications. Vertical Paddle Wheel TYPE FHPP. Cross section and close up of each wheel showing each one has 4 arms with 3 paddle boards on each arm.
Top view of the unit showing 2 parallel trains and each train is to be made of 5 wheels compartments in series. Low tip speeds create a gentle rotary mixing which promotes floc devel-opment. Design the first compartment of one train of a Horizontal-Shaft Paddle Flocculator.
Unit Operations and Processes in Environmental Engineering. Provide energy and gentle mixing to induce particle collisions that form large flocs which will settle in a sedimentation basin or clarifier. Example Paddle wheel flocculator design A cross flow horizontal shaft paddle wheel tapered flocculation basin with 3 compartments square in profile having equal depths are to be designed for a flow of 65 MGD.
WesTech can also supply all supporting equipment for a complete package such as torque monitoring and protection. Day flow with all trains operating. The flexibility to install a number of flocculators on a single drive.
Horizontal Paddle Wheel TYPE FVPW. Relative paddle velocity to water v. Typical G-t for flocculation is 2 x 10 4 - 10 5.
Flocculator Design Overview Analysis of hydraulic flocculators Ratio of maximum to average energy dissipation rate Inefficiency of energy use due to nonuniformity of energy dissipation rate The great transition at Ø 55 Flocculator Design Head loss collision potential residence time. Relative paddle velocity to water v 0. Large G and small t produce small but dense flocs.
Application Description Most drinking water is stored in surface reservoirs where the water picks up materials such as dirt and plant matter. Water density p 0. Top Bottom left.
Proper flocculator design affects the ability of the treatment facility to remove particles in standard treatment facilities. JMS can design and manufacture 3 styles of Flocculators.
