Packaged Plants

Polypropylene Construction 

300 m3/d (80,000 GPD) Package WWTP Installed Within a Residential Subdivision
Polypropylene packaged plants are fabricated from very durable polypropylene panels welded by heat fusion. Composed of one or more bioreactor modules, plants ranging up to 20,000 GPD/100 m3/d (or population equivalent of 350 PE) are supplied. (Larger package plants have been manufactured, however steel or concrete tank construction is generally more cost efficient). The plants are strong but light and easily shippable. Installation is undemanding. After setting the tanks on concrete or compacted sand bed pads, pipes are connected and the tanks are backfilled. The tanks are installed below ground (or partially below ground) and covered with lockable wooden planks or reinforced plastic lids.
Steel Construction Steel construction packaged plants are shop pre-fabricated from ¼“ thick plate, sandblasted and painted before shipment and installation on a concrete pad above or below ground. Plants ranging up to 100,000 GPD/380 m3/d (or population equivalent of 1,200 PE) are supplied. (Larger steel tank packaged plants have been manufactured, but concrete tank construction is generally more cost efficient). 90 m3/d (25,000 GPD) Subdivision And Golf Course WWTP
