Does 'Skin' Matter in TDS? The Effect of Biofilm on Water Quality Readings
•

Recent research has shown that revolving algal biofilms can reduce Total Dissolved Solids (TDS) levels in wastewater by up to 27%, highlighting the significant chemical activity of these microbial layers. This demonstrates that the 'skin' that forms on surfaces in contact with water, known as biofilm, is far from inert and can dramatically affect water quality measurements, including those from a TDS meter.
