Biofilm build-up prevention on filters for multi and single-pass water systems.

Feb 20 2020

Amazon Filters new SupaSpun KilBac® and SupaGard Kilbac® filters use the latest innovation in high-performance antimicrobial and antialgal additives to prevent Biofilm build-up on filters for multi and single-pass water systems.

With applications in water processing across many industry sectors, KilBac’s meltblown fibre construction is designed to prevent biofilm build-up on filters in both multi and single-pass water systems.

Crucially, the underlying technology harnesses micron-sized particles containing active silver, zinc and copper.

Combined with a base polymer, the metals are incorporated in different combinations to combat the growth of bacteria or algae on the filter.

Precise control of fibre diameters during manufacturing ensures that the maximum area of antimicrobial material is exposed, which optimises performance.

The launch follows a rigorous testing programme which demonstrated KilBac’s effectiveness against biofouling and the subsequent filter blockage or sloughing off of contaminants that can blind membrane systems downstream.

Key to KilBac’s success is its ability to inhibit bacterial and algal growth by disrupting metabolic activity at cellular levels.

It is ideal for any application where potential biofouling of a water-based filtration system can occur.

Target industry sectors include building services, power generation, chemicals and coatings, oil and gas, pharmaceuticals and healthcare, and food and beverages.

In building services for example, filter life on sidestream installations can be extended along with the potential to aid control of overall bioburden in the system.

In oil and gas production, KilBac filters can be used to prevent premature blinding of SRP (single recognition particle) membranes with algae.

Amazon Filters Managing Director Neil Pizzey said: “KilBac is the latest addition to our solutions portfolio and is perfect for any process water system that is stop-start and so not in continual flow.

“In all kinds of water-based recirculation processes there can be a persistent problem with microbial contamination and the subsequent biofouling of filters.

“You find this in physical blockages of the filter as well as the sloughing-off of micro-organisms growing on the filtration media.

“The upshot is typically an interruption to your manufacturing process and therefore increased costs to put it right.

“In response, KilBac prevents biofilm build-up to avoid any interruption, extending the lifetimes of water systems and so reducing operating costs for our customers.”

While both inhibit the growth of bacteria and algae, SupaSpun Kilbac is an absolute depth filter while SupaGard Kilbac is a nominal depth filter.

The difference is that a nominal filter has broader manufacturing tolerances, so enabling greater variations in effective porosity.

The products look the same and have similar void volumes but they offer different performance efficiencies.

Customer choice will depend on specific applications, desired outcomes and budget.
