Sedimentation involves one or more basins, called "clarifiers." Clarifiers are relatively large open tanks that are either circular or rectangular in shape. In properly designed clarifiers, the velocity of the water is reduced so that gravity is the predominant force acting on the water/solids suspension.
These pumps are proving their reliability and efficiency worldwide in: • minerals processing; • coal preparation; • chemical processing; • effluent handling; • sand and gravel; • and almost every other tank, pit or hole-in-the-ground slurry handling situation.
A study was performed using modified swirl sedimentation tanks. The vortex separators (OW, OWK, OWR and OWKR) have been studied under laboratory conditions at liquid flow rate from 2.8⋅10-5 to 5.1⋅10-4 [m3/s]. The pressure drop and the efficiency of purification of liquid stream were analyzed.

The width of influence 'B' in open waters is obtained as 'B' = [ 7.7 + 20 (1-Cb)2] b, where 'b' is the breadth of the ship. The 'B' value in open waters varies from about 8*b for large tankers to about 9.5*b for general cargo vessels to about 12*b for container and passenger ships.
Concrete ring tank sections can be used to form water tanks with a capacity of around 2 000 litres. enough in the well to be submerged in water at all times. The pump handle is connected to the plunger by means of a long Domestic, stock Slurries domestic. Chapter 19 - Water supply and sanitation. SS is removed by filtration and sedimentation. BOD is mainly reduced by aerating the water.
3 THEORY Also referred as 'SEDIMENTATION TANKS'. Settling- process by which particulates Gravity settling- the particles will tend to fall to the bottom of the vessel, forming a slurry at the vessel base. 8 DESIGN In specifying a water and wastewater sedimentation tank size, the major features to be sedimentation tanks; three conditions are commonly considered: - solid handling capacity...
Conversely, temperatures which are too low will result in a high asphaltic content slurry. Safe work practices and appropriate personal protective equipment are needed when handling spent catalyst. Following pretreatment, suspended solids are removed by sedimentation or air flotation. Tanks are also provided for fire water, process and treatment water, acids, air and hydrogen, additives and...

The opportunity of technological and modified lignosulphonate wastes, process water, oxygenized brown coal with high content huminic acid (to 60 %) with alkali usage as plasticizer agent in the coal-water slurry (CWS) production technological process was checked.
Therefore, the process can handle caking coals, unlike the conventional dry-ash gasier. Approxi-mately 50% of the coal ash drops out as slag into a slag quench tank below the gasier. Fluidized coal is mixed with either oil or water to make it into pumpable slurry. gasication never be attempted in a severely fractured area, in shallow seams, or in coal seams adjoining porous sedimentary layers.
Flocculation tank: raw water with flocculants flow into flocculation tank from inlet pipe, through the agitator, suspended solids are reacted with flocculants and become alum flocs. Sedimentation tank: alum flocs flow to sedimentation tank, by th plate settler/lamellar, solid and liquid are separated.

Water-treating equipment that makes use of gravity separation includes skim tanks, API separators, plate coalescers, and skim piles. CPIs require frequent cleaning of the plate packs in which large amounts of sediment are handled. Water and sediment flow outward against the underside of the disc. The lime (calcium oxide) is premixed in water as slurry and fed immediately below the spray.
The coal-water slurry is pumped through an externally heated, coiled, metallic tube and flashed into a suspension of coal particles in steam. A rapid increase in the velocity of this suspension causes some size degradation and considerable turbulence, both contributing to a rapid reaction between steam and coal.
