The dependence of the scattered radiation on the degree of flocculation is the basis of instruments designed to measure flocculation. Flocculation tanks are to be designed for a total flow rate of 49200 m3d. Many water treatment plants use a combination of coagulation sedimentation filtration and disinfection to provide clean safe drinking water to the public.

It is an. It seems prudent therefore to design flocculat-ing and mixing equipment with over-sized variable-speed drives so that the mixing intensity can be adjusted to suit changing conditions. The flocculation basin has a width of 2743 m to connect with the adjacent sedimentation.

A flocculation basin is 50 ft long by 22 ft wide and contains water to a depth of 11 ft 6 in. The basin is to be a cross-flow horizontal-shaft paddle-wheel type with a mean velocity gradient of 267sec 1 at 50F a detention time of 45 min and a GT value from 50000 to 100000.

A The basin dimensions if increments of 1in. The flocculation basin is 8 feet deep 19 feet wide adn 50 feet long. This preview shows page 1 - 2 out of 3 pages.

Assume a water temperature of 10 C a detention time of. Horizontal flow is used for very high flow rates to avoid building the plants even. The Flocculation Monitor developed by Tioxide Europe Ltd measures the flocculation of pigment in wet and dry films.

Detention time 5 min G 150s 1 at 10C length 2 times width depth 30m diffuser depth 275m. They enable floe to toler-ate higher mixing intensities. A flocculation basin is to be designed for a water coagulation plant and the design flow for the basin is 130 MGD.

Download scientific diagram Details of coagulation tanks Flocculation Flocculation is the process of slow mixing that can be achieved in a basin which is known as a flocculator. Example Problem A cross-flow horizontal-shaft paddle-wheel flocculation basin is to be design for a flow of 65 MGD a mean velocity gradient of 30 s -1 at 50F and a detention time of 50 min. The basin is to be squared with a depth equal to 125 times the width.

A plant treats a flow of 24 MGD. How many gallons of water are in the tank. Volume ft 3 50 ft x 19 ft x 8 ft.

The total flocculation time is to be 21 min and the water temperature is 15 C. Now you can calculate the basin volume. The basin is to be a cross-flow tapered agitation system with a total detention time of 45 min.

Volume ft 3 Length ft x Width ft x Depth ft. First determine the volume of the flocculation basin in feet. Flocculation aids are being used in-creasingly.

The GT value should be from 50000 to 100000. This flocculator program determines the size number and spacing of the flocculator channels and baffles based on the results of the Computational Fluid Dynamics CFD team and the specification of horizontal flow. For dry films samples of different thicknesses are irradiated with light of 25 μm wavelength.
