Our operations and maintenance team are experts at optimising and improving efficiency of membrane filtration systems, which has led to significant cost savings for customers and increased the lifespan of their assets.
In this article we explain the various membrane and filtration systems available, how you can cut operating costs and gain maximum benefit from existing assets, and provide advice for finding the most cost-effective and efficient solution when it is time to upgrade or repair.
Membrane filtration systems use high pressure to force water through the membranes. Fouling or blockages in the membrane drive up energy costs and cause performance issues as the system works harder to push water through.
Microfiltration
A microfiltration system uses a porous membrane to separate suspended particles and larger molecules from a liquid or gas. It selectively allows smaller particles and solvent to pass through while trapping larger contaminants.
Ultrafiltration
Ultrafiltration systems employ a semi-permeable membrane to separate suspended solids, bacteria, and macromolecules from wastewater. It is highly effective in purifying wastewater to achieve higher levels of water quality and meet stringent regulatory standards.
Nanofiltration
Nanofiltration technology uses specialised membranes to remove various contaminants, including dissolved solids, organic compounds, and divalent ions. This process is effective in producing high-quality treated water, suitable to reuse.
Reverse Osmosis
Reverse Osmosis (RO) systems use a semipermeable membrane to remove dissolved solids, ions, and contaminants from wastewater. It operates by applying pressure to push water molecules through the membrane while blocking larger molecules and impurities. This produces high quality purified water for reuse, or to meet strict regulatory standards.
Refurbishment and remedial work on filtration and MBR systems can be complex, high risk and expensive, so it is critical to get it right. Alpheus are specialists in operations, maintenance and construction of wastewater treatment assets and lead the way in safety to ensure work is carried out safely and effectively.
To ensure continued and efficient running of the filtration systems, membranes should be replaced every five to ten years (depending on the type and condition). As an independent provider, we are often able to supply and fit high quality membranes and parts at a more competitive price than purchasing from the original manufacturer, as we have access to a wide range of approved suppliers.
Our experienced team are highly trained in specialist Health and Safety practices such as Confined Spaces and lifting operations, and are optimisation specialists, so you can be assured of a quality installation.
Many membrane filtration systems incorporate automated Cleaning In Place (CIP) technology. However, incomplete or inefficient set up could contribute to higher energy costs and lead to performance issues and compliance issues.
Different plants and sectors will have unique needs, so CIP systems should be set up, monitored and optimised on an ongoing basis. It is not uncommon for these systems to be ineffectively set up.
Read how we helped a leading plant based food manufacturer recover their membranes and establish cleaning programmes to make significant cost savings and improve plant performance.
