What is the Reverse Osmosis Equipment Manufacturer's (ROEM) Role in Membrane Water Treatment?

Posted by Julie Nemeth-Harn on Feb 14, 2020 11:00:00 AM

In conventional construction projects there are three main parties: the water treatment plant owner, the engineer, and the contractor. In specialized process projects a system supplier with particular expertise on the process is also usually involved. This party is also called an Original Equipment Manufacturer (OEM). For membrane treatment projects this entity is commonly called the Reverse Osmosis Equipment Manufacturer (ROEM) or the Membrane System Supplier (MSS). The ROEM or MSS may have a separate contract with the water treatment plant owner, or they may be a subcontractor to either the engineer or the main general contractor.

How Global Warming and Climate Change Presents Major Water Treatment Challenges

Posted by Julie Nemeth-Harn on Jan 31, 2020 10:48:00 AM

The effects of global warming and climate change are continuously being felt on the earth. In fact, we are expected to experience a 2-5 degrees Celsius increase in global temperatures within the next 30 years. An effect of climate change that often gets overlooked is its impact felt on water treatment processes.

Climate change poses major challenges to the effective treatment of water. Some of these challenges include inundated water supplies that lead to higher levels of contaminants in the water, pressure on the operation of current water infrastructure, and the effect of inclement weather on water systems.
