Reliable, Performant Systems

Our membrane plants are built to unlock more value from your milk and whey streams. We design and install tailored UF, MF, NF and RO systems that deliver consistent separation, concentration and purification, helping manufacturers increase yields, cut waste and improve product quality. Every plant is engineered for reliability, easy integration and long‑term performance.

Spiral wound module selection

We have extensive experience in the selecting the correct membrane elements for the required duty. There are a number of considerations when selecting membrane elements, some of these include:

  • plant design requirements, MF, UF, NF RO
  • feed stock type, solids, flowrate and quality
  • feed stock temperature
  • required concentration factor
  • required mass balance of the process
  • CIP requirements
  • plant run time

All of these factors affect what type of membrane is required.

Feed pre‑treatment

As part of the overall process, there may be requirements for pre-treatment of the feed stock before supplying the membrane plant. We are able to provide a robust and reliable solution to many feed stock challenges. Some of these include:

  • Clarification
  • Separation
  • Pasteurisation
  • Inline filtration
  • Temperature control

Pumping, valving and instrumentation specification

There is such a wide range of process equipment on the market, selecting the correct device for the application can be difficult. We are able to select suitable pumps, valving, instrumentation, IO hardware and PLC components for use in hygienic food environments.

Automation with detailed process parameter monitoring

There is a wide range of instrumentation available to monitor the various process parameters of a membrane plant. Dependent upon the product, these could include the following:

  • flow
  • pressure
  • temperature
  • turbidity
  • pH
  • conductivity
  • total solids

Trials, commissioning, performance mapping and training

Membrane plants can demand a large capital expenditure which means justification and confidence in their capability to deliver is a requirement. To help customers get to this point, we are able to pilot production runs using test rigs of various sizes. These are able to process quantities from 25lr all the way up to 1000lrs to be able to prove the process at a scale that suits. All of the membrane types can be trialled in this way.

Once a full size plant is up and running, its performance can be monitored by the use of relevant instrumentation and by regular sampling. This is all part of the service we can offer. In order to keep the plant running efficiently, well trained and competent operators are a necessity. We are able to provide training as required into how the membrane plant works, how it should be operated and how to correctly maintain it.

Lifecycle support: integrity testing, membrane changeout, spares

All membrane elements have a lifespan which when exceeded can lead to poor performance, poor quality and usually an unhappy customer. Ideally, the membrane should be changed out before it reaches this point and at a time that suits the customers plant. This can be achieved by regular monitoring of the performance of the membrane plant to give a good idea of degradation of the membranes.

As part of supplying replacement membrane elements, we’re also able to install the elements. This can usually be fitted in around production requirements of site to minimise downtime costs. Replacement plant hardware such as o-rings, ATDs, permeate elbows or complete housings can also be supplied as required, often to match existing equipment.

Expansion of existing membrane filtration plants

As throughput and site capacities increase, membrane plants must follow suit. Membrane plants are very scalable and can be increased in capacity reasonably easily. When a customer wants to change the duty of a plant, there is some key information required:

  • flowrate
  • temperature
  • feed stock details
  • required runtime
  • required concentration
  • other upstream/downstream modifications

Based on this information, we will review the existing plant configuration and performance to identify what modifications will be required in order to achieve the new duty. Modifications could include:

  • Changing existing pumps or adding existing pumps
  • Changing line sizes
  • Adding vessels to existing loops
  • Adding complete loops to the plant
  • Changing the type or specification of the membrane elements

Cleaning strategy design (CIP sequences, chemicals, flux recovery)

CIP or ‘Cleaning In Place’ is a critical part of any membrane system. As part of any process, fouling will eventually occur on the membrane surface which can effect the product quality, plant performance and membrane lifespan. An effective CIP system needs to recover a plant to it’s original state ready for the next production run. The problem comes when trying to do this without damaging the delicate membrane surface.  There are a number of improvements that can make the CIP safe and effective:

  • tried and tested CIP regime to effectively clean the membrane plant. Control of feed flow, concentrate flow, loop boost, temperature, CIP bypass all contribute to achieving this.
  • automatic chemical dosing systems to insure a reliable and consistent introduction of chemicals.
  • an automatic flux test to check the performance of the membrane plant following each CIP. This gives a comparable flux figure to show CIP to CIP performance.
  • continuous pH monitoring to ensure that chemical strengths are within the chemical supplier recommended strengths to achieve effective cleaning, but also that they are not so strong that they can damage the membrane.
