Patent ID: 7470361

Claim:
A liquid treatment system comprising: a) a control structure member having a housing containing an upstream control chamber and a downstream control chamber separated by a partition, an upstream convergence drain pipe opening into said upstream control chamber, and a downstream convergence drain pipe opening into said downstream control chamber; b) a first end of a treatment water inlet pipe extending into the upstream control chamber of said control structure member; c) a second end of said treatment water inlet pipe connected to an interceptor structure member, said interceptor structure member including a housing containing an upstream interceptor chamber and a downstream interceptor chamber; d) a first end of a treatment water outlet pipe connected to the downstream interceptor chamber of said interceptor structure member; e) a second end of said treatment water outlet pipe extending into the downstream control chamber of said control structure member; and f) wherein the housing of said control structure member is spaced apart from the housing of said interceptor structure member, whereby said control structure member and said interceptor structure member may be independently constructed and independently installed at different times.
