In-Pipe Technology improves water quality for discharge or reuse by reducing influent organic loading and effluent pollutant levels. In-Pipe has helped compliant plants function more effi ciently and has helped non-compliant plants achieve their targets.

By initiating productive microbiological activity in the collection system, In-Pipe digests organic matter as it moves through the entire system improving the influent bioavailability.

In-Pipe can structure treatment design to address industrial inputs into the
collection system. It works with both conventional treatment processes and new
designs using membrane bioreactors.

Figure 4 compares influent Total Suspended Solids (TSS) at a 14 MGD municipal
plant during In-Pipe treatment with those of the same months of the preceding year
prior to treatment. With In-Pipe, the plant achieved a 25% reduction in total pounds
of infl uent TSS concurrent with a 6% MGD fl ow increase.

Figure 5 compares effl uent Biological Oxygen Demand (BOD) at an 8 MGD municipal
plant during 3 years of In-Pipe treatment with those of the same months of the
preceding 3 years without In-Pipe treatment. With In-Pipe, the plant achieved a 65%
reduction in the BOD load in the effluent.
