Many engineers size the system to continuously filter the cooling tower basin water at a rate equivalent to 10% of the total circulation flow rate.

This way, you're not fighting gravity or going against the way your circulation flows, so you'll get the optimum effect.

These keep your circulation flowing, your balance fine-tuned, and your muscles fit.

Interestingly, forced circulation evaporators in the food industry use modified designs that mimic the original system however involve extra secondary steam units to enhance forced circulation flow.
