Case Study
Hard Water Problems with New Boiler System
Overview
Project Overview: Following a client’s installation of 2 new Bosch Boilers in their boiler house they contacted Newsome Ltd to establish if there could be a solution found to the problems being experienced with hard water despite having an existing water softening system installed.
Following the installation of two new Bosch Boilers in their boiler house, a client reached out to Newsome Ltd to address persistent hard water issues that remained unresolved despite having an existing water softening system in place.
Background
Hard water entering a boiler is severe as it can lead to excess use of chemicals and deposits of scale on the boiler heat exchanger. Even small amounts of scale reduce fuel & water efficiency increasing operating costs. Soft water is free from such metals as Calcium, Iron, or Magnesium.
Objectives
Newsome were contacted to find a solution to the ongoing hard water problems that persisted despite the client’s existing water softening system.
Solutions
Boilers are fed from 2 hot water wells. To prevent further damage a water softening system was designing to meet peaks in demand which also needed to take into account the ability to operate independently or simultaneously with a piping system, control valves and sensors. The system provided constant availability at an instant with an available flow of 4m3/h.
Analysis
The system design was a “duplex co current ion exchange softening system with salt regeneration” controlled volumetrically by a water meter which ensured softened water 24/7 at optimal efficiency.
Installation
A pre-packaged skid mounted system was designed & built with high efficiency resin to ensure minimal waste of salt and water. Included was a low voltage control panel to take level sensors and motorised valves. A simplified control logic could be applied to control each hotwell feed independently or simultaneously as required by demand.
Conclusion
In conclusion, the implementation of the pre-packaged skid-mounted system, designed with high-efficiency resin, successfully addressed the client’s hard water issues by minimizing salt and water waste. The inclusion of a low voltage control panel and motorized valves, along with simplified control logic, ensured efficient and flexible management of the hotwell feeds, meeting the client’s demand requirements effectively.
