Electro-conductive properties were determined by measuring permeate electric conductivity, using a C535--Consort conductometer
The pH was measured with pH meter (Elico LI-120), electrical conductivity was measured with conductometer
(Elico Nitrite, Phosphate and Sulphates were estimated using colorimeter (Elico LI-120).
Conductivity was measured using a Metrohm conductometer
measuring cell and Metrohm model 644 conductometer
Conductivity measurements were made by using Digital Conductometer
Oxygen levels were monitored with a Microprocessor Oximeter OXI 96, the salinity with an LF 196 conductometer
The conductivity was measured using a WTW conductometer
, model InoLab[R] Cond level 2, with a TetraCon 325 electrode.
While conductivity measurements were carried out with a metrohm 660 conductometer
Electric conductivity of the solution samples were measured by the conductometer
LF 330/SET by WTW GmbH.
The ammonia removal has been monitored conductometrically, using a Radelkis OK-112 conductometer
and by swelling studies.
