Table 4

Nomenclature for reliability mathematical model.

S0, S3, S6:Operative state of Phytoremediation process.
S1, S2, S4, S5:Failure state of Phytoremediation process.
Sj:Water Quality Parameter COD range 100-2000 mg L−1
Ps:C. vulgaris is in unreactive mode (standby mode)
Po:C. vulgaris is in reactive mode.
S1F:Failure due to low range of j.
S2F:Failure due to high range of j.
TEi:Textile Effluent in different concentration
where i = 1-5(10%, 25%, 50%,75%,100%).
P1:Probability of j ≥ lower range of COD.
P2:Probability of j ≤ upper range of COD
P3:Probability of TEi in required concentration when i = 1-3.
P4:Probability in 500 mg L−1 C. vulgaris required amount.
q1:Failure Probability of i not greater than lower range of parameters.
q2:Failure Probability of i not less than upper range of parameters.
q3:Failure Probability of TEi of concentration when i = 4 & 5.
q4: Failure probability of C. vulgaris amount less than 500 mg.
XTP:Success state of treatment of TE.
XTF:Failure state due to TE of concentration i = 4 & 5.
XFP:Failure state due to algae with less amount.
r1:Replacement cost due to failure in initial stage (S1F and S2F).
r2:Replacement cost due to failure in treatment stage (XTF and XFP).
