Condensing results Initial data sets benchmarking standard glass media have shown ~ 40 % water capture from the vapour stream
Drainage rate (or passive collection) 32˚ 67.7˚ 78.7˚ Synthetic urine vapour. Flow rate (4 LPM), BV (0.13 L), v (2.9 m/min), EBCT (1.95 s), temperature differential (< 2°C) 32.0° Increased hydrophilicity apparently enhances moisture retention Does hydrophobicity govern drainage efficiency?

Lipids contain the elements Carbon Hydrogen Oxygen There are two main groups: Triglycerides Phospholipids.
Freeze Drying fish. Introduction In freeze drying, foods are dried in two stages, first by sublimation to approximately 15% moisture content (on wet weight.
What are Lipids? – Nonpolar, organic molecules – Composed of hydrogen (H), carbon (C), and oxygen (O) – Lipids consist of two types of molecules - glycerol.

What is Osmosis? Osmosis is a form of passive transport (no extra energy needs to be used) where water molecules move down their concentration gradient.
