The Royal United Hospitals NHS Foundation Trust has identified an urgent requirement for the flushing/treatment of heating systems as
part of its wider Decarbonisation Project. The Trust is seeking to improve the operational efficiency, reliability and longevity of several
Low Temperature Hot Water (LTHW) heating systems across the estate through the implementation of a comprehensive water treatment
and side-stream filtration solution.

The existing heating systems require ongoing protection from the adverse effects of corrosion, scale formation, suspended solids,
magnetite accumulation and air ingress, all of which can reduce system efficiency, increase energy consumption and contribute to
premature plant failure. As part of the Trust's decarbonisation objectives, maintaining optimal water quality within these systems is
essential to support efficient heat generation and distribution, reduce energy losses and minimise maintenance requirements.
The proposed solution comprises the installation and commissioning of ENWA EnwaMatic® side-stream filtration and water treatment
units across six separate LTHW systems serving the Wolfson, MRI, South, X-Ray, Z-Level and Central plant areas. The equipment
provides continuous side-stream filtration to below 10 microns, pH control, corrosion inhibition, scale control, air removal and reduction
of bacterial growth potential within the heating systems. The solution is designed as an alternative to conventional chemical dosing
regimes and is intended to provide long-term maintenance of water quality and system performance.
The requirement includes the supply of filtration units, automated backwash controls with Building Management System (BMS)
integration, dedicated circulation pumps, break tanks, delivery and manufacturer-led commissioning. Manufacturer commissioning is
required to validate equipment warranties and ensure the systems are operating in accordance with the intended design parameters.
Delivery and installation of the water treatment solutions will support the Trust's objectives of improving heating system efficiency,
reducing lifecycle maintenance costs, protecting critical infrastructure and contributing towards the Trust's sustainability and carbon
reduction targets.
