This paper has presented application and implementation of fuzzy logic controller (FLC) for feed chemical concentration process. It is desired to improve the chemical composition of a feed chemical concentration control system whose initial response was undesirable. In order to achieve the objective of the paper, the dynamic model of a typical chemical concentration with a feed-flow valve is obtained and presented in the form of a transfer function. A fuzzy logic controller is designed using fuzzy block of the Simulink. Simulations are performed in MATLAB/Simulink environment considering two cases. The first simulation was performed considering the case where the designed controller has not been added to the closed-loop. The second simulation was performed considering the case where the FLC has been included in the close-loop. The Simulation results obtained showed that the output composition performance of the process was largely improved and maintain steady state within the acceptable percentage of the output composition
