Realistic Filtration Device

The Problem

High-capacity reliable seawater microfiltration technologies are sought after in many sectors; oil and gas, aquaculture, water production and shipping to mention only a few. However, field tests and operational experiences show that many of the existing ļ¬lters on the market have inadequate self-cleaning abilities, resulting in serious clogging problems. This results in significant unexpected downtime, unscheduled maintenance, higher energy costs and inadequate water treatment with the risk of severe downstream process failures.

The Approach

From experiencing disappointment in applications using filtration systems delivered from reliable suppliers this project was initiated. Improved reliability beyond that of the competition, minimisation of pressure and energy losses, optimisation of stresses and strains and full scale long and short term testing of a concept prototype has been carried out. To effectively present envisaged product to investors and potential suppliers the benefits of virtual modelling were utilised in order to demonstrate and portray the application and potential of the technical innovation at low cost.

The Result

The first mild-steel single multi-screen high capacity microfiltration unit was built in 2011 with retention capability at 40 micrometres and a flow rate of 3300 m3/hr. Later, a range of filter units were developed providing high quality filters in duplex steel quality at a cost competitive to that of inferior mild-steel products. The competitive advantages being massive weight savings, hugely improved quality and maintenance free housings. IPR development has focused highly and the products are successfully patented.
