Flovac’s first project in South Korea

/in , /by

This is a unique project, designed and installed by Flovac’s partners in South Korea Coway EnTech Co. Ltd.

Mr Changil Koh the Deputy Manager in charge of the project, said that vacuum systems are very useful in handling the wastewater from the offices and facilities in industrial projects such as Nuclear Power Plants.  they have also been installed in Oil Refineries and at airport facilities as no power is required at the collection points only at the vacuum station. This means that there are no points of ignition risk within the system.

Mr Koh said that the laying of the HDPE pipework was  a lot easier than using gravity sewers as it could be installed above ground where required or in shallow trenches. There is more than 2 kilometers of pipework involved. Most area’s where industrial complexes are built in flat areas with difficult to construct ground conditions. This is ideal for vacuum sewers.

The Shin-Kori Nuclear Power Plant #5,6 – Sanitary Water Transfer Facility in Busan will be providing much needed power by 2022. It is owned and operated by Korea Hydro & Nuclear Power, a subsidiary of KEPCO. Flovac was chosen for this important project after an exhaustive trial to ensure that all of the Flovac components could handle the extreme conditions where temperatures can often drop to well below freezing.

Upgrading your Vacuum Pump Station

/0 Comments/in , /by

The Vacuum Sewerage Industry is now 50 years old and for a variety of reasons some of the systems infrastructure will need to be replaced or upgraded. It could well be a move away from old liquid ring pumps. It could be that some of the equipment has just come to the end of its expected life. You may have inherited assets that were never looked after as per the suppliers manuals.

Hopefully you have a station that was designed with the future change out of equipment in mind. Large doors and a cranes to get pumps out of the building. A roof that can be dismantled without too much problem to get the tank out and replaced. Fortunately the building was designed so that upgrades or refurbishment could occur. A new stainless steel tank was installed. An upgrade can give the utility a chance to look carefully at the catchment area with fresh eyes. Have the daily household flow rates gone down, have you installed new monitoring systems that have sorted out any infiltration.

Are there more houses or another developer that you could now accept into your catchment if the pumps were slightly larger? The Flovac Engineering Group is often asked for advise on the upgrading of a vacuum pump station and as the group has designed more than 300 stations and probably designed the one you are now upgrading, they would be the best people to speak to.

The Flovac Operations Group is the next point of call. What changes have there been to suppliers equipment, what lessons have been learned from hundreds of systems around the world. Are there changes to health and safety regulations. What impact will there be on power use, ventilation and odor. The most important aspect is what is your plan to upgrade a system that is now live without major problems.

The operations group have been involved with the installation of more than 300 vacuum stations and the upgrade of more than 50 stations. Flovac can supply containerized vacuum stations to support the upgrade.
