Pure Water Systems

Window cleaners are faced with high expectations from customers to provide a streak and spot free finish, free from impurities such as particles, salts and ions that cause them. Not only this, but the service demands for high volumes of water, typically drawn from an IBC tank.

Tank fills need to be swift and regular when doing jobs on the daily, so you need a system that enables you to produce pure water quickly and on demand. This method is preferable to van mounted setups, where a tank is stored inside a vehicle, able to move to each cleaning location.

The most efficient way of producing this scale of purified water is using a reverse osmosis system, pre treated using particle and chlorine filtration to prolong the service life of the RO membrane. This process will remove ~99% of ions, salts and other contaminants, ready for a final polishing DI resin stage.

Deionised water is of ultra pure quality, meaning it attracts contaminants such as dirt to stabilise itself, leaving surfaces without any build up. The use of RO water during deionisation will also prolong the service life of the resin used, saving money and time on resin replacements.

Treatment Process

1

Particle Removal

Our cartridges offer outstanding absorption of sediment, dirt, sand and scale flakes to prevent filtration systems from blockage and microorganism growth.

2

Chlorine and Organics Removal

Carbon cartridges are a long established choice for the reduction and removal of chlorine, VOCs and heavy metals whilst reducing water hardness.

3

Reverse Osmosis

Pure water (permeate)  is produced during reverse osmosis by applying pressure to force water through a semi permeable membrane, leaving a majority of the present ions and dissolved solids on the other side to drain as waste (concentrate).

4

Post RO Deionisation

Our performance mixed bed resin is specially designed for deionisation directly after reverse osmosis. It holds a 1 : 1.5 ratio of strong acid cations and strong base anions to attract and remove all ions, salts and dissolved solids.

5

Storage

Water storage tanks are fed with purified water to hold, ready to be pulled to the point of use. They also act as the barrier between pure water and outside contamination, removing the risk of spoiled water.

6

Pumping

Water transfer pumps are the key to pulling stationary water, typically within an IBC tank. At the desired flow rate, they will boost pressures up to 100 psi (6.9 bar).
