NOV Mono pressure system receives accolade in Australia

NOV Mono has secured a major industry certification for its Pressure Sewer System (PSS).

Mono's InviziQ system has been awarded the certification by the Water Services Association of Australia (WSAA) making Mono the only PSS manufacturer in Australia to receive this recognition. The WSAA certification is awarded for various criteria, including meeting WSAA standards, technical compliances, manufacturing quality and performance.

The system is gaining popularity as a replacement for conventional gravity-fed domestic sewer networks, as it offers the freedom to build in new areas without the need to worry about sewering restrictions, slope requirements, environmental concerns or difficult terrain. InviziQ does not rely on gravity and provides a more reliable and controllable transfer of sewage from the household to the treatment plant than conventional alternatives. As a sealed system it also eliminates many of the traditional environmental issues such as leakage (which contaminates ground water supplies) and unpleasant odours from raw sewage.

Mono's standard InviziQ system has a storage tank with an approximate 900l capacity, a Progressing Cavity (PC) pump incorporating a macerator which grinds the sewage to a workable slurry, and an automatic electronic controller which regulates the flow, monitors fluid levels and protects the pump.

The system also has a Dry Well feature, which keeps the pump motor, fluid level sensor and electrical systems separate from the fluid being pumped. This unique system uses a vertically-mounted pump cassette inserted into the tank through a hole in the Dry Well, and ensures that the pump is suspended without the requirements for a foot which can cause ragging. From an operational health and safety perspective, this also makes accessing the system for servicing a far easier and safer process which involves no contact with the sewage.

InviziQ offers environmental management benefits by allowing effective control and monitoring of sewage networks. This allows the water authorities to manage sewage inflows into the treatment plants effectively.
