Answer / raj kumar

mixd bed has the mixture of resin as strong base anion and
strong acid cation. so due to presence of acid cation ph is
reduced

Answer / amrut maisuria

why water passes first in SAC and then SBA ?

Answer / a n jha

it seems ratio of cation and anion resin quantity are not in
balance.if the cation resin is more than anion resin,ph of
dm water shall go less than 7 i.e. it will be acidic in nature.

Answer / nitesh raghuwanshi

When water passed from SBA AND COMES IN MB , MB CATCH SOME MORE ION THAT WHY WE GET LESS PH & LESS CONDUCTIVITY , LESS SILICA Water . Another reason in MB IN TOP ANION RISEN IN BOTTAM CATION RISEN SO WHEN WATER COMS IN MB FIRST ITS ALKALI BECAUSE OF ANION RISEN AFTER ITS ACIDIC FOR CATION RISEN.

Answer / shaik.subhani

dm plant heart of the mb this meaning mixed bed first of all
sac out let water is coming now mbvessul top side anion
reesin bottom side cation resin water is comming anion that
is the high ph water converted to low ph

Answer / alok behera

In Mb, cation resin release H+ ion, and Anion resin released OH ion. That means H+ and OH- ion. So that is pure water. Normally pure water ph is 6.2 to 7.5. So mixed bed ph decrese.

Answer / amit katiyar

Mixed bed is used only for polishing of impurities which is remain or slippagefrom SBA like sio2 sodium act due to it lower size and shape. mixed bed contains both resin cation and anion so here remained inpurities are exchanged and pure water gained that means lower in ph conductivity and silica act.

Answer / adas

Due dissolve carbon dioxide the PH is acidic

BIOCHEMICAL ENGINEERING INSTRUMENTATION - EXAMPLE 29.4 : The resolution of separation, Rs for chromatography is given by the formula Rs = (difference in retention time) / (average width at the base). In a chromatogram, 3 peaks a, b and c are found. Average widths W at the bases of the solutes are : Wa = 20 s, Wb = 40 s, Wc = 30 s. Resolutions of separation, Rs for solutes b and c in comparison to a are 2 and 4 respectively. The differences in retention times T for b and c in comparison to a are (Tb - Ta) and (Tc - Ta), Ta = Tc - Tb : (a) Form 2 equations involving Rs as a function of Wa, Wb, Wc, Ta, Tb and Tc. (b) Find the values of Ta, Tb and Tc.

BIOPROCESS ENGINEERING - EXAMPLE 14.2 : An aqueous solution with 2.5 g of a protein dissolved in 600 cubic centimeters of a solution at 20 degree Celsius was placed in a container that has a water-permeable membrane. Water permeated through the membrane until the h - level of the solution was 0.9 cm above the pure water. (a) Calculate the absolute temperature of the solution, T in Kelvin, where T (Kelvin) = T (degree Celsius) + 273.15. (b) Calculate the osmotic pressure, P of the solution by using the formula P = hrg where h is level of the solution, r is density of water with 1000 kg per cubic meter, g = 9.81 N / kg as gravitational acceleration. (c) Calculate the concentration of the protein solution, C in kg / cubic meter. (d) Calculate the molecular weight of the protein, (MW) = CRT / P where R = 8.314 Pa cubic meter / (mol K) as ideal gas constant.
