A common misconception concerning IFAS systems is the longevity of the installation and down time a basin has to suffer. A lot of people aren’t aware that the process is actually quite painless. Entex Webitat units come preassembled. Therefore, there is no field assembly required.
The Entex Technologies Webitat System is generally used as a secondary wastewater treatment application. Its primary purpose is to increase nitrification capacity by adding surface area for additional biomass growth.
Entex Technologies generally works as a subcontractor to the General Contractor and Consulting Engineer during municipal projects. There are only four steps involved in the Entex Webitat installation.
Step 1: The Lift
Entex Webitat units are assembled with a minimum of 6 heavy duty lifting lugs. This helps to maximize the customers lifting options. A crane is typically used to lift the modules. Shackles are recommended for crane lifts. Units can weigh up to 3,000 pounds. The rigging and lift process takes approximately 10 minutes per unit.
Step 2: The Placement
Entex engineers design each unit to avoid interferences with other in basin equipment while simultaneously maximizing treatment benefits. Under normal circumstances, the units are oriented such that the BioWebTM is parallel with the direction of flow. The placement and orientation of each unit normally takes less than 10 minutes.
Step 3: The Anchor
Each leg has a square base plate with 3 holes for anchoring. Once the units have been positioned correctly, each leg is typically anchored into the concrete using either epoxy style anchors or expansion anchors. Drilling will be required. The anchor process typically takes 30 minutes per unit.
Step 4: The Air Connection
Each Webitat unit comes preassembled with an integral coarse bubble air scour system located underneath each unit. The air scour will be made of either 304L SS or SCH 80 PVC. The final step in the installation process is connection of an external air supply to the 2” MNPT connection underneath each unit. Connection time will take less than 5 minutes per unit.
