1. A passive filter cell for filtering an effluent with suspended substances, the passive filter cell comprising:
a basin with a floor and two or more upright sidewalls forming a channel having a first sidewall, a second sidewall, back sidewall, and a front sidewall, said floor is configured on an angle from said first sidewall to said second sidewall;
an inlet having a width configured to reduce a velocity of a flow of the effluent and increase removal of suspended substances from the effluent, said inlet positioned proximate a top of said front sidewall to receive the effluent and an outlet having a width to reduce a velocity of a flow of the effluent and increase removal of suspended substances from the effluent, said outlet positioned proximate a top of said back sidewall to exit the effluent, wherein said front sidewall having a height configured to reduce a velocity of a flow of the effluent and increase removal of suspended substances from the effluent, said front sidewall is downwardly curved from said inlet to said floor; and
a discharge pipe positioned proximate a junction between said floor and said second sidewall.
