Much appreciated.
Must be properly design such as the settling velocity of the flocs and the max flow. If not, you may experience some carry over flocs which will affect your final water quality.

Pro:
High removal in a small footprint.
Cost-effective way to upgrade an existing plant
Cost-effective on sites that have footprint issues, such as coastal sites
May enhance the removal of suspended solids
Con:
May perform badly if flows exceed design maximum
Will perform badly if sludge blanket is allowed to get high and enter tubes
Tubes may break
Tube less easy to clean than plates, if they get fouled
UK experience is that they require regular cleaning, so may impose greater operational cost
Shorter life than conventional concrete-based settling tanks
Typically produce larger volumes of sludge, with lower DS, than conventional systems

Definite advantage in terms of space relative to conventional Dortmund or flat bottomed scraped settlers
Be wary of spacing between plates and angle of plates - there are minimum design criteria
work well on inorganic chemical treatment processes and low sludge biological process applications, as secondary settling behind RBC for example
But be mindful of bio fouling at high sludge concentrations
anything else, drop me a line

This facility is for a drinking water treatment plant and hence i feel biological process shall not be of prime importance. Moreover, the highest level of turbidity around the year is 90 NTU maximum.

Then it should perform well if operated within the design constraints, good luck

It depends of use. If it is used in WWTP be careful with clogging.

smaller footprint but higher per ft2 construction cost. look at https://youtu.be/nL8IhkFt3bs
