Purite, a leading UK manufacturer of water purification equipment, has launched a new range of ultrafiltration systems that are capable of providing flow rates of between 5 and 100m3/hour The new systems are specifically designed for the pre-treatment of mains water, in particular for the removal of colloids from heavily contaminated raw waters

Water purification system options
Water is an essential raw material for a wide range of cleanroom applications, being used in production operations and for research and development: what are the options for purification?
The new Purite ultrafiltration plants are primarily for use in conjunction with high flow reverse osmosis systems and are designed to remove contaminants such as particulates, micro-organisms, inorganic colloids and organic macromolecules including pyrogens, from raw water.
Depending on requirements, the new ultrafiltration plants can be designed to incorporate multiple streams, with redundancy built in as necessary.
Unlike competing technologies, such as cartridge filters, the associated running costs are considerably lower.
Each filtration module within the ultrafiltration plant is constructed from hydrophilic polyether sulphone hollow fibres, this structure effectively guarantees high levels of physical and chemical stability.
The filters are capable of removing contaminants from 5000 - 150,000 Daltons.
Backwashing can be chemically enhanced to remove dissolved organics and bacteria through the use of alkalised agents, or a chlorine based disinfecting agent.
Additionally, cleaning and backwashing duties can be automated and constantly monitored and controlled by a dedicated microprocessor control system.
This automated approach allows plant performance to remain consistent, thereby helping to minimise any potential fall off in flow rate.
Automated cleaning cycles are triggered by the detection of an increase in differential pressure across the membranes, a reduction of flow or on a time basis.
In common with all Purite equipment, the new ultrafiltration systems are backed by the company's 24/7 service and support capability, available as a standard service contract, or a flexible package tailored to individual needs.
The 24/7 service facility gives customers access to highly qualified Purite engineers at any time of day or night.
