Info

1 Lab-Module M 20The Lab-Module has a membrane area of 7.9 sq ft. (0.72 sqm). The module is equippedwith polysulfone membrane support and spacer plates. The module can operate ata pressure of up to 1000 psi (80 bar), pH 0-14 and temperature up to 212 degF(100 degC). The membrane used in the module may be less resistant and therebyset operating limits.Each membrane support plate is provided with a small outlet to collect the permeateindividually which allows for simultaneous testing of multiple flat sheetmembranes.The module base is a built-in hydraulic cylinder, activated by hand operated hydraulicpump, to be able to compress the module after mounting the membranes.1 Pressure Regulating ValveThe module pressure can be regulated by the spring-loaded valve. Itfunctions as a safety valve for the feed pump. The valve outlet isconnected with a hose to direct the flow.1 2540 Membrane VesselThe housing is 2.5” in diameter and 40” long. The housing is rated up to 1000 psig.The housing is 316SS.1 Ceramic HousingThe ceramic housing is constructed of 316 stainless steel for testingdiameter by 250 mm length ceramic elements.10mm18
Process Description and Plant OperationWater Quality SpecificationsWater used for flushing, cleaning and disinfection of Model L plants must conform to thefollowing standards to obtain the best possible results.It is a prerequisite that the following standards be adhered to for membrane guarantee to bevalid. It is also recommended that the water be analyzed at least every three months toensure proper quality. If the water quality does not meet these standards, consult a NiroInc. representative.Iron (Fe)Manganese (Mn)Silicate (Si02 )Aluminum (Al)Hardness as CaCO 3ParticlesTurbiditySilt Density Index(SDI)Total Plate CountColi CountChlorineLess than 0.05 ppmLess than 0.02 ppmLess than 10 ppmLess than 1 ppmLess than 10 gr/gal (170 ppm)ppmLess than 25 micronsLess than 1 NTULess than 3Less than 1000 per ml0 per 100 mlUndetectableOxidizer IntoleranceAny deviation from the above may influence the performance of the plant.If you have a reverse osmosis or nano-filtration system, the membranes have no tolerancefor oxidizers. Introduction of any oxidizers, especially chlorine (sodium hypochlorite),will cause permanent damage.19
