TDS Creep

The 'TDS Creep' phenomenon, a significant challenge in Reverse Osmosis systems, is primarily caused by the membrane and Remineralisers.

​

When a Reverse Osmosis (RO) system is not in operation (when the storage tank is full), the semipermeable membrane experiences natural 'Osmosis' due to the absence of pressure being applied. This results in a temporary spike in the Total Dissolved Solids (TDS) output when the system resumes water production. A membrane 'Flush' procedure is commonly employed to mitigate this issue. Modit has revolutionised this by incorporating an innovative flush system controlled via an adjustable timer. TDS creep is completely eliminated by setting the timer to a maximum of 30 seconds while conserving 80% less water than traditional flushing methods. This forefront solution offers unparalleled efficiency and flexibility in TDS output management.

It must be noted that systems without a membrane flush function (unpowered systems) will accumulate increasing TDS levels in the storage tank over time, negating any claimed membrane rejection percentage, and higher TDS rejection rates require higher P:B ratios.

​

Remineralisers serve as sacrificial devices to infuse water with minerals, such as calcium and magnesium. The water's mineral dissolution level is determined by water contact time. During periods when the system is inactive, the extended contact time allows higher quantities of minerals to dissolve into the water, consequently increasing the TDS and altering parameters. However, unlike the membrane creep phenomenon, the short burst of altered water upon system activation from the remineraliser is viewed favourably due to its beneficial attributes. Therefore, no specific actions are taken to rectify this phenomenon, as its effects are considered advantageous.

About us Modit specialises in identifying anomalies in mechanical & electrical products or systems and offering efficient, practical solutions often unavailable elsewhere. Our passion for excellence drives us to achieve specific targets, even when the sought after solution isn't readily accessible. Through our "Mod(ify)-it" approach, we tailor solutions to meet particular requirements. Other solutions are highly customised, exclusive, or not widely marketable. One of our flagship creations is the highly-tuned drinking water RO system, meticulously designed to specific requirements that can't be found off the shelf. Our commitment is to provide you with a waterwise, cost effective, high quality water filtration system that can be easily installed and maintained. Our product is engineered to deliver clean, revitalising, and safe drinking water on tap. Everyone deserves access to high quality water at negligible cost. With 13 extensive years of field experience in the commercial application of Reverse Osmosis systems, we have come to understand the importance of a tailored approach. We recognise the significance of post-RO remineralisation and the need for water usage reduction in the Reverse Osmosis process. We know that each water application requires specific parameter values for optimal performance, whether it's for drinking, coffee brewing, cleaning, or other purposes. For instance, the ideal water parameters for brewing coffee are different from those for general drinking water, ensuring the best extraction and equipment longevity. Our system traces its origins back to a journey sparked by personal curiosity. Initially developed for personal use, it quickly gained widespread acclaim due to its exceptional performance. However, its custom-tuned nature made it inaccessible for purchase. Recognising the demand, we're seizing the opportunity to make this outstanding system available to everyone.
