Liquid wastewater samples were taken from the output of the secondary treatment, the clarifier-settled tank effluent, whereas the sludge samples were collected from drying tanks that were exposed to the outdoors.

There are some areas, like Chicago, that have not seen a spike in roadside service calls from drivers with dry tanks, but roadside assistance agencies said the calls had increased so sharply coast-to-coast that they started monitoring closely for repeat callers.
Thus, we develop a novel device, Chemical Post-Processing Integrated Equipment (CPPIE), which can deal with crystallization, filtration, washing and drying in the same tank by changing the position of it.
Short-term interruptions of the continuous and automated system operation were mainly caused by external problems, such as "supply pump dry run", low level or completely dry inflow tank, and the aeration chamber level was very low.
Feed and fecal samples were dried, pooled on tank basis (applied for feces only) and homogenized by grinding before subsequent analyses of dry matter, nitrogen, energy, lipid and yttrium oxide.
