Question

definition of priming , homing, scale, slug, lime soda process, zeolite soda process,ione exchanger process, gravity sand filter

Answer 1

 Lime Soda process is a method of softening hard water. This process is now obsolete but was very useful for the treatment of large volumes of hard water.

Priming: a substance which primes something for use or action, in particular.

Homing:  the inherent ability of an animal to navigate towards an original location through unfamiliar areas.

Ion exchange:  Ion exchange is an exchange of ions between two electrolytes or between an electrolyte solution and a complex. In most cases the term is used to denote the processes of purification, separation, and decontamination of aqueous and other ion-containing solutions with solid polymeric or mineralic "ion exchangers".

zeolite solution:  Zeolite process for water softening has become a commercial success for the reason that zeolite can be easily regenerated.

Answer 2

Priming = it's a technique which influences one stimulus to the other without intention
Homing= ability of an animal to return to its territory after traveling away
Scale= small bony plates protecting the bony plates of fishes and reptiles
Slug= any apparently she'll least animal
