Advanced Technocracy Inc. is Manufacturer, Exporter & Supplier of SCR Commutation Techniques.
The Filterability Apparatus utilises a bed of granular material, which can be chosen by the investigator to suit their own purposes.
The measurements taken with this apparatus enable a filterability number to be calculated, which has significance in deep-bed filter performance.
The apparatus can also be used for a part of the testing of media for water andwaste water filtration.
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.
Flow meter range:
Apparatus to verify Darcy’s Law, to examine Kozeny’s equation and to observe liquid fluidisation behaviour of a granular bed. Equipment consists of a metal framework, constant head tank and transparent test section for observation. Flow is indicated by a Rotameter.
A 0.5m water differential manometer and 0.5m Mercury manometer are included for pressure drop across the bed.
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.Technical Details:
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:
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.
Ion Exchange Unit is used to exchange the ions. The transfer of ions occurs between two electrolytes or between an electrolyte solution and a complex. Ion exchange refers to purification, separation, and decontamination of aqueous.
Applications of Ion Exchange:
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.

There are various types of Anaerobic Digester:
Types of Anaerobic Digester:

In addition the following basic differencies of the two stages of the process can be demonstrated:
It is the process which is used for biological treatment such as aerobic microbes to stabilize the solids. The mass of received organic waste is also reduced by using biologically destroying volatile solids.
Aerobic and facultative microorganisms use oxygen and get the energy from the accessible biodegradable organic matter in the waste sludge. For this process, we have all products of best quality.Specification:
