Pure water systems installation – explained

Pure water is needed for a huge variety of purposes, be it for domestic, hospitality, or healthcare facilities, or for industrial applications and manufacturing processes. Read on for pure water systems installation – explained.

What pure water systems are available?

The type of system depends on the final water specification and volume requirement. A system for domestic drinking water would vary in size and specification compared to a car manufacturer using 25,000 litres/ hour, for instance. Large industrial applications can require upwards of 30,000 litres/ hour at European or US Pharmacopeia specification. A pure water system installation may include several stages and types of equipment to achieve the necessary standard and volume of water.

How are pure water systems installed?

A water purification system can be installed anywhere it is needed. It will be designed, manufactured, and installed by specialist water treatment engineers. We carry out a site visit to assess the customer’s requirement and the physical space available. If space is at a minimum, we find a way to accommodate the most appropriate system. For instance, we’ve previously designed a bespoke RO system with wall mounted units for a compact space. Installation is often as simple as placing the new system on a desktop and plugging it in, or it could take several weeks. It depends on the business and its operation.


What impurities need removing to produce pure water?

Everything that is a negative component dissolved in water needs removing. It also depends on the final water specification supplied by the customer or suggested by us. The types of impurities in water include dust, dirt, chemicals, biological contaminants, organics, gases, and suspended solids.

Is there a scale for measuring water purity?

Yes, water purity is measured either by electrical conductivity in micro-Siemens, or electrical resistivity in megohms, over a given distance (1 cm). Generally, the more impurities present in a water sample, the higher the conductivity (an electric current will pass through it more easily) and the lower the resistivity. Conductivity and resistivity are the inverse of each other, and 1 micro-Siemen is equal to 1 megohm.

What are the most common pure water systems?

Ion Exchange forms the basis of many forms of water purification and is perhaps the most common method used when designing a system. Filtration also forms at least some part of most systems and Reverse Osmosis (RO) is also quite common.

What are the running costs?

Running costs vary widely but are typically manageable for businesses. Initially the cost of feed water has to be factored in, followed by electrical supply and any chemicals used for regeneration. Consumable parts such as filters, servicing, and maintenance should be considered too. The reality is that it’s not possible to generalise on the cost of a pure water system without a site survey and water testing to assess the requirement.
