—Seasons affect the rainfall and river current. Thus,
the quality of raw water from rivers as well as the property of
water treatment residue (WTR) from water treatment plant are
season-dependent. In this research, the season-dependent
properties of WTR as compacted clay from five treatment plants
located in the central of Thailand has been studied. These
properties included Liquid Limit (LL), Plastic Limit (PL),
Shrinkage Limit (SL), particles size, Optimum Moisture
Content (OMC), and Unconfined Compressive Strength (UCS).
It is found that the seasons and the sources of raw water in
Thailand slightly affected the properties of WTR. The highest
quality WTR was obtained from Tha Chin River, especially,
those collected at the end of winter. A comparison between clay
and WTR properties showed that their physical properties were
similar. However, their strength and permeability were
different. Clay-WTR mixture with the ratio of 1:1 is
recommended for landfill liner because it offers comparable
properties with clay but with a lower material cost.
