In which process of membrane separation, the accumulated particles are brought back into the feed solution?

In which process of membrane separation, the accumulated particles are brought back into the feed solution? Correct Answer Microfiltration

The particles accumulated in the process of membrane separation are brought back into the feed solution by the shear induction erosion of the cake in the process of microfiltration. The factors other than that like particles-particles interaction as well as the inertial lift forces accounts to the back-transport of the particles away from the membrane.

Which of the following statements are correct regarding the general difference between cell and nuclear membranes? 1. A cell membrane occurs in both Eukaryotes and Prokaryotes while a Nuclear membrane occurs only in Eukaryotes.  2. Both cell membrane and nuclear membrane persists throughout the lifetime of a cell. 3. The main feature of the nuclear membrane is the presence of two lipid bilayer structures while a cell membrane has single lipid bilayer structures.

A chemical solution appears green when the salt concentration is 8 grams per litre (gpl) and red when it is 10 gpl. Pure water was added to the solution of 1 litre of 15 gpl solution till it turned green. Then 125 ml of the green solution is taken out and x grams of salt is added to the green solution to make it red. Another 500 ml of the final solution was taken out and y litres of green solution is added to get a resultant solution of concentration 9.6 gpl.  Assume adding salt doesn’t change its volume and find the ratio of x and y. 
The critical reasoning question is based on a short argument, a set of statements, or a plan of action. For each question, select the best answer of the choices given. The size of particles is directly linked to their potential for causing health problems. Small particles less than 10 micrometers in diameter cause the greatest problems, as they can get deep into the lungs and some may get into the bloodstream. One being exposed to such particles can affect both the lungs and the heart of a person. But there are particles that are causing environmental effects too, few of which are given below.  Which among the following below options does not talk about the effects of these particles on the environment?

It is desired to concentrate a 20% salt solution (20 kg of salt in 100 kg of solution) to a 30% salt solution in an evaporator. Consider a feed of 300 kg/min at 30°C. The boiling point of the solution is 110°C, the latent heat of vaporisation is 2100 kJ/kg and the specific heat of the solution is 4 kJ/(kgK). The rate at which the heat has to be supplied in (kJ/min) to the evaporator is
