Pneumatic ejectors are designed to lift liquids and solids in suspension by means of compressed air. Is this statement true or false?

The statement is true because pneumatic ejectors operate by using compressed air to create a lifting force that can elevate both liquids and solids in suspension. This mechanism relies on the principle of air pressure, which, when applied in a specific manner, can effectively move materials. Pneumatic ejectors possess the ability to handle a mixture of solids and liquids, making them versatile for various applications, especially in wastewater treatment processes where the removal or transfer of sludge and other materials is necessary.

In different contexts, the design and operational specifications of pneumatic ejectors might vary. Some may be tailored more towards lifting solids, others towards fluids, or both, but the fundamental principle behind their operation as described remains valid. Thus, acknowledging that pneumatic ejectors function effectively for both liquids and suspended solids supports the accuracy of the statement.
