the hull cell is a miniature plating unit designed to producecathode deposits on a panel that correlates the characteristicsof the plating unit being evaluated. interpretation ofthe as plated cathode panel give rapid information aboutbrightness levels, irregular plate deposits, uniformity of deposits, coverage, throwing power, impurities, and plating bathchemistry.

application

a portable miniatureplating cell is employed using the following components.

• a rectifier(d.c. power source) with variable controls foramperage from 0-10 amps, 0-12 volts. this power sourceshould have less than 5% ripple
• hull cell anodeas the same asis in the plating unit or as recommended by the chemicalsupplier. example: zinc anode for zinc plating bath.
• color coded coated cablescapable of carrying the currentrequired with an alligator clip soldered to cell end. colorcode recognized universally is as follows: anode +black; cathode red.
• hull cell cathode panelstwo most widely used are zincplated steel and thin plastic protected brass panels.dimensions:10cm x 6.5 cm
• hull cell potwith prescribed solution level line, 267 ml, 524 ml, or 1000 ml size. the most commonly used size is the 267ml. hull cells are available in pp, acrylic, pvc
• agitation hull cellspecially designed for introducingair into the miniature plating unit to duplicate air agitationoperations.
• timerseparate or built into the dc power unit depending upon the sophistication desired.
• heater and temperature controller if required

features

wastewater from metal finishing industries contains high concentrations of contaminants which are hazardous to the environment.it is necessary to provide treatment of effluent before it is suitable for discharge into the sewer.the equipment for treatment of effluents may be classified under following major headings
batch treatment plants
continuous flow treatment
fundamentally, all effluent treatment systems consist of a series for suitably lined process tanks with appropriate mixing and regent dosing facilities, followed by sedimentation tanks, filters, flow and ph monitoring as required. additional facilities for sludge and strong waste process solutions handling are also necessary
