    Permeability and Fluidisation Studies Apparatus

    The apparatus can also be used for a part of the testing of media for water andwaste water filtration.

    Demonstration Capabilitie

    • Pressure drop measurements and correlations for flow through packed beds
    • Verification of Kozeny’s equation
    • Characteristics of a liquid fluidised bed
    • Measurement of permeability of selected solids
    • Attrition tests.

    Description

    A bed of granular medium (usually sand, but other materials can be used such as Ballotini or anthracite) is placed in a readily demountable tube through which water can be made to flow in either a downwards or upwards direction.

    Flow from a laboratory tap passes through a constant head tank, which also allows air bubbles to be released, and is controlled by hand with a needle valve. The rate of flow is indicated by a variable area meter.

    Pressure drop across the bed can be measured either by a 0.5m length water differential manometer or a 0.5m length Mercury manometer (see recommended accessories), depending on the magnitude. Valves are fitted for isolation of various parts of the circuit, together with air release valves.

    The test section tube and all tubing connections are transparent so that operation can be observed and the presence of air bubbles easily detected. All metal fittings are corrosion resistant.

    No power connections are required and the whole apparatus can be lifted and transported by one person. Test material (Ballotini) for the packed bed is supplied but Mercury for the manometer is not included.

    Sedimentation Studies Apparatus

    Sedimentation is the process for the simplification of water and wastewater. Particles settled from the suspension depends on the two things which is the concentration of the suspension and the characteristics of the particles.

    In this process, the sedimentation is the process to study the different characteristics of sedimentation. Students can resolve the effects of initial concentration and initial suspension height on sedimentation rates. With these effects you can also determine the effect of particle size distribution and the using of flocculating agents.

    Flocculation Test Unit

    It is used  to conduct  to conduct the flocculation test in the laboratory. This test is also known as “Jar Test”. It consists of 6 Nos. of Glass Flocculating vessels.  These are situated on  translucent base and lightened from the bottom by a florescent lamp.

    Specification:
    • A bench top unit comprising an internally illuminated base and a backboard supporting a control console.
    • Six stirrers with stainless steel paddle shafts and blades linked to a variable speed motor.
    • Stirrer speed range typically 25-240 rpm.
    • Stirrer assemblies are easily demounted to allow the test vessels to be removed and cleaned.
    • Digital timer 1-99 minutes.
    • Two adjustable pre-set programs.
    Capabilities:
    • Determination of optimum coagulant dosage
    • Determination of optimum pH
    • Effect of mixing time and intensity on aggregation
    • Coagulation tests in conjunction with activated carbon.
    Description:

    Analysis of a water or waste preparatory to the design of a treatment sequence often involves coagulation and flocculation tests, ‘Jar tests’, in the laboratory.
    Jar tests are routinely used for the control of plan operations and are performed by treatment plant operators.

    The tests serve to indicate the optimum chemical dosages for removal of turbidity and colour, including such parameters as pH adjustment, and the supplemental use of activated carbon. Jar tests, furthermore, yield a wealth of qualitative information on the rate of agglomeration as a function of energy input (paddle speed), the settleability of the floc formed, the clarity of the supernatant water (which might be related to the subsequent length of filter run).

    Coagulation and flocculation tests may be used, in conjunction with other tests, to study basic processes including, for example, the kinetics of reaction and the removal of trace constituents from aqueous solution.

    A bench-mounted framework incorporates facilities for six tests to be carried out simultaneously. The glass flocculating vessels stand on a translucent base which is illuminated from below. Each flocculating vessel incorporates a stirrer paddle driven by a variable speed drive. The paddle assemblies are easily withdrawn for removal and cleaning of the test vessels.

    The paddle shafts are made of stainless steel to resist corrosion. Paddle speed is accurately maintained by electronic feedback control. A digital display clearly indicates the speed which is fully variable. Alternatively, the use of two adjustable presets allows repetition of pre-selected speeds.

    A digital timer can be set to count down from 1 to 99 minutes. After count
    down the paddles stop and an alert sounds.

    Technical Details:

     

    • Dimensions of paddle blade: 50mm x 15mm
    • Stirrer speed range: 25-240rpm (approx.)
    • Sample volume: 1 litre (each vessel)

    Ion Exchange Unit

    • Food & beverage,
    • Hydrometallurgy,
    • Metals finishing,
    • Chemical & petrochemical,
    • Pharmaceutical
    • Sugar & sweeteners,
    • Ground & potable water,
    • Nuclear,
    • Softening & industrial water,
    • Semiconductor,
    • Power

    Demonstration Capabilities

    •  The exchange capacities of different resin materials
    • Water softening using a cationic resin
    • Regeneration efficiency of a softening system
    • Demineralisation using two-bed exchange
    • Regeneration efficiency of a cationic and anionic resin

     

    Water Softening Theory
    The usual ion exchange material employed in water softening is a sulphonated styrene-based resin, supplied in the sodium form. This has a strong affinity for calcium and magnesium ions and will also remove ferrous ions after the almost complete removal of calcium and magnesium. Softening may be carried out as a batch process by stirring a suspension of resin in the water until equilibrium or an acceptable level of hardness is reached. It is more convenient to operate as a continuous flow process, passing the water slowly downwards through a column of resin beads. The exchange reaction takes place rapidly enough for the upper layers of the bed to approach exhaustion before the lower layers are able to exchange ions. Thus there is a zone of active exchange which moves down the column until the resin at all depths becomes exhausted. The position at an intermediate stage is illustrated.

    When the zone of active exchange reaches the bottom of the column the emerging water begins to show an increasing hardness. This is the breakthrough point when it becomes necessary to regenerate the resin with a strong sodium chloride solution.

    Pump: Self priming diaphragm type
    Flowmeter range: 10-80ml/min
    Sump tank capacity: 20 litres

In addition the following basic differencies of the two stages of the process can be demonstrated:
    • the low level of methanogenic activity during acidogenesis compared to methanogenesis
    • the low level of COD removal exhibited by the acidogenic stage compared with the methanogenic stage.
