Calibration and support

Enviroquip based in Austin, Texas is among the manufacturers that utilizes our field support services. We provide a comprehensive support package to them for every MBR (Membrane Bio Reactor) they provide to private and municipal sewerage authorities within our territory.

We provide a walk through with the customer, general contractor, electrical contractor and Enviroquip approximately 2 weeks to 2 months prior to the startup. This helps ensure that all components have been installed and wired properly and nothing has been overlooked during the construction of the facility.

The MBR systems provided by Enviroquip can be complex. They are generally made up of three large concrete inground tanks, various pumps and level switchs controlling the pumps and blowers. There are usually two types of blowers for the systems. The systems also have automated valves, mixers and based on levels and flows various components interact with each other. There can be a SCADA system or the main system can be integrated into an existing SCADA system. The main system also has various HMIs and digital totalizers. The systems range in size and scope from ~$1 million to over $15 million.

During startup up we spend from one to four weeks calibrating, configuring, wiring and checking every component, HMI, PLC, transmitter, meter, totalizer, level switch setting, etc. We follow the factory recommended setup procedures for every device on the system. We also document everything we do for our follow report.

We also usually have to configure an automated dialer to dial out to an operator if an alarm condition exists in off hours.

While on site we also perform system training for the operators with a recommended maintenance schedule where necessary.

After the startup our followup documentation package includes electrical and mechanical drawings of any changes, copies of any PLC program changes that were made, photographs of the system once complete, photographs of any issues or problematic components and a comprehensive daily log. We also include a list of any punch list items or open items that need further action, by others or by us.

During the warranty period if Enviroquip requires a representative on site to perform any troubleshooting we typically represent them. We perform any repairs or swap out components as necessary.
