US-headquartered SPX FLOW, Inc., a provider of process solutions for the nutrition, health and industrial markets, has launched a sustainability initiative the company said drastically reduces the total amount of clean water a homogenizer uses.

The Homogenizer Water Recycling System (HWRS) is designed to recycle up to 97% of the water used by homogenizers. Traditionally, a continual flow of water gets supplied to homogenizers to cool the transmission oil and lubricate the plungers. The HWRS technology recaptures that water, sanitizes and chills it, then returns it to the homogenizer.

The amount of water that can be saved depends on the homogenizer, but SPX FLOW said the HWRS can save up to 2m gallons each year (7,500m3). For context, it takes almost three seconds for that much water to flow over Niagara Falls.

“Water recycling has become increasingly urgent as the cost of water and sewer bills rise and the availability of water shrinks,”​ said Con O’Driscoll, SPX FLOW’s global product manager of dispersion products.

“We believe sustainability is paramount, and we are continually developing innovative processes and solutions to help our customers reach their goals. The HWRS is a great example.”

The HWRS meets the drinking water regulatory standards set by the Pasteurized Milk Ordinance (PMO).

It can be used with both new and existing homogenizers made by any manufacturer. It is compact at 21 x 32 inches (533.4 x 812.8 mm), and if any problems emerge, the HWRS has its own control system, including features that would default to fresh water without causing downtime.

“This is a proven, plug-and-play technology,”​ O’Driscoll said.

“It’s easy to retrofit and simple to implement.”

The HWRS is the latest water-saving technology from SPX FLOW: The company holds more than 850 patents worldwide, and approximately 44% of the patent families are related to sustainability and clean technology.
