Passive Screens versus Intake Structures
What are the main pros and cons for both intake systems to lean forward any of them when designing abstraction of raw water? From the environmental point of view, suction velocity at the intake structure can be set up in such a way to minimize impingement.
My first thought is that passive screens would skip the requirement to install coarse and fine screens and also serve as intake structure, two in a row and therefore a more budget friendly solution.
Regarding cleaning and chlorination, also these are requirements for regular intake structures, therefore in my opinion always passive screens are a better option.
