Our membrane modules and housings have been carefully designed to achieve the maximum membrane surface area. They allow optimum operating parameters, such as crossflow velocity, pressure and temperature to be established ensuring optimum membrane performance. Tubular membranes are mostly intended for high solids or large suspended solids, are usually polymeric with range from 4 – 25 mm internal diameter.
Modules and Housings
Depending on application type; a wide range of module type can be used. Ranging from an A series module configuration in A5, A19 and A37 system in stainless steel housing or A8 system in GRP or stainless-steel housing; with membranes cast in epoxy resin at each end. The B1 series comprises of 18 perforated stainless-steel tubes in a form of shell and tube, with each tube fitted with a membrane element and housed in a stainless-steel module. The C10 series comprises of 72 perforated plastic support tube, with each housing a membrane element and a module in ABS material.
Developing a System
PCI Membranes has over 50 years’ experience in developing cost effective solutions to liquid separation problems. Its comprehensive range of laboratory services and pilot plants enables PCI Membranes to tackle a wide range of applications from antibiotic broths to dye house wastewater.
Experience with a wide range of crossflow membranes and an unbiased membrane selection procedure means a truly independent solution for each application can be developed.
Choosing the right membrane
A full range of polymeric tubular membranes is offered. This range allows PCI Membranes to test right across the filtration spectrum from reverse osmosis, through nanofiltration and ultrafiltration to microfiltration.
Trials can either be carried out in PCI Membranes’ laboratories or on-site by clients, with or without assistance.
Versatile pilot plants
PCI Membranes pilot plants are designed for pilot scale work and may be used to process a wide variety of aqueous solutions using reverse osmosis, nanofiltration, ultrafiltration or microfiltration membrane. A wide range of membranes is available to suit the application requirement. And can be operated over a range of pH, temperature, pressure and flow rate.
The pilot units are equipped with instrumentation necessary for scale up data to be collected accurately and easily, whilst customization is possible to allow for small scale production requirements in continuous, semi-continuous or batch operation.
Optimising plant design
Using a dedicated applications database, engineers objectively select the best membrane and geometry for a given application. During pilot trials these membranes can be evaluated and the process tested.
The optimum full-scale plant design can be developed using proprietary design programs for batch or continuous plant operation.
PCI Membranes manufactures and assembles engineered systems in-house working to the appropriate industry requirements such as FDA. Plant control and automation can be developed and fully validated in-house prior to delivery.
Systems can be installed and commissioned under the direction of PCI-Membranes engineers who would be responsible for ensuring that the upstream and downstream conditions satisfy the operating requirements of the system.
Operator training is considered to be one of the most important services provided. This is an integral part of the whole design, build and supply package which PCI Membranes specialises in providing.
PCI membranes can provide technical support, training, commissioning, process optimisation and a remembraning service to clients.
Regular service visits can be offered on a contract basis to maintain plant installations and to ensure optimum plant performance.
