SUSTAINABLE WATER SOLUTION
30% reduction in CO2 released during operation. The technology itself is constructed using materials that have a 99% recyclable potential, facilitating effective reuse when it reaches the end of its long service life. Veolia Water Technologies commented: “Working with those that know and trust our products is always great, but it is particularly rewarding to be able to build on a relationship with a new piece of technology that will continue to reliably deliver, as the existing unit has, for many years to come.”

Veolia Water Technologies’ ORION 2000S has helped expand pharmaceutical production capacity and reduce water footprint
fter purchasing Veolia Water Technologies’ new ORION 2000S RO and CEDI unit, a major healthcare goods manufacturer has been able to significantly expand its production capacity and reduce its water footprint by up to 40%. In addition to its range of consumer healthcare goods, the facility in the southeast of England was seeking to expand its production capabilities to include a range of allergy relief products, of which water is a major component. In order to achieve this, the customer needed to expand its capacity for the production of pure water that would comply with US pharmacopoeia standards. An ORION 4000S has previously been used to supply the purified water required for the manufacturer’s existing site. When a system was needed for the new facility, the customer felt confident reaching out to Veolia Water Technologies for a solution. The team recommended an ORION 2000S, providing an additional 2000l/hr of purified water. The ORION series, developed for the pharmaceutical and cosmetics industry, uses a combination of pretreatment, reverse osmosis (RO) and continuous electro- deionisation (CEDI) technologies to deliver high-purity water for a variety of applications. The system can be regularly hot water sanitised above 80˚C, offering preventative microbial protection over the system’s lifespan. The ORION S is the most sustainable model in the range as it reduces energy and water consumption and optimises water recovery, enabling the system to reduce the volume of water sent to drain. The ORION S also delivers minimal OPEX costs. This also facilitates a lower environmental impact, providing a potential
A 26 APRIL 2025 | PROCESS & CONTROL CLAMP-ON TECHNOLOGY IMPROVES EFFICIENCY AND SAFETY
low measurement plays a critical role in industrial processes, particularly in the chemical industry, where accuracy and safety are paramount. Traditional flow measurement methods often pose challenges when dealing with highly corrosive gases like hydrogen chloride (HCl). To overcome these difficulties, clamp-on ultrasonic flow measurement has emerged as a non-intrusive, efficient, and safer alternative.

Hydrochloric acid is a fundamental chemical used across multiple industries, from ore processing to pharmaceuticals. Its production involves the absorption of hydrogen chloride gas into water, with precise control over the gas and water flow rates being essential to achieving the target concentration of 38% HCl.
At an industrial site producing high-purity hydrochloric acid, the flow of HCl gas into an absorption column was traditionally measured using a differential pressure-based flow meter. However, this method presented several challenges: • The HCl gas had low pressure, making traditional differential pressure-based flow measurement challenging.
• The gas’s high corrosiveness necessitated plastic pipelines and specialised equipment. • The previous system required two shut-off valves for maintenance, demanding extensive protective measures, including full breathing apparatus for personnel. In order to enhance plant safety and operational efficiency, engineers sought an alternative measurement solution. Non-intrusive clamp-on ultrasonic flow measurement technology provided a simple yet highly effective option. This method operates by transmitting ultrasonic signals through the pipe walls and analysing their interaction with the gas flow inside. Since there is no direct contact with the medium, maintenance issues are reduced.
Given the low-pressure conditions of HCl gas, initial scepticism surrounded the feasibility of ultrasonic measurement. However, a four-week trial demonstrated that the technology could reliably and accurately measure gas flow under these conditions. The success was largely attributed to the acoustic properties of the plastic piping, which facilitated effective ultrasonic signal transmission even at atmospheric or negative pressure. The adoption of clamp-on ultrasonic flow measurement delivered several key advantages: • Enhanced Safety: Eliminating invasive components reduced exposure risks, improving workplace safety. • Lower Maintenance Costs: No direct contact with the corrosive gas eliminated the need for frequent equipment replacement and complex maintenance procedures. • Accurate Measurement Across All Operating States: Unlike pressure differential methods, ultrasonic technology provided consistent readings across varying flow rates, from system start-up to shutdown.
