The revolution of the standardization process in sanitation systems

The process of standardization in sanitation systems that use membranes, such as reverse osmosis (RO), ultrafiltration (UF) or nanofiltration (NF) units, is essential to monitor system performance over time and ensure treatment efficiency .

Standardization

Normalizing operating data means adjusting operational data (such as permeated flow and rejection) for standard conditions. This is done so that operators can compare the actual performance of the system at different times, regardless of variations in parameters such as temperature, pressure and concentration of dissolved solids.

Impact of permeated flows and rejection

• First Stage : The flow permeated in the first stage usually has greater flow, as it is the starting point where most of the pressure is applied. Standardization here is critical to detect whether there is fouling (clogging) in membranes or other forms of degradation.
• According to the stage : In the second stage, the permeated flow tends to be lower due to decreased transmembrane pressure and increased concentration of dissolved solids. Data standardization of this stage helps identify specific performance problems of this point, such as increased fouling or membrane damage.
• Rejection : The rejection rate, or the capacity of the contaminant retaining membrane, also needs to be normalized. Standardization helps to verify that the membrane continues to reject contaminants efficiently over time, even with variations in the composition of food and operating conditions.

Standardization and efficiency calculations

Normalizing the data allows:

• Operational Efficiency : Identification of performance falls not related to external variations, allowing preventive interventions.
• Chemical reduction : precise monitoring that optimizes cleaning routines, reducing the use of chemicals, environmental impact

Innovation with Bridgemeter

While traditional standardization is manually performed at most three times a day and calculations are made in spreadsheets, Above-Net has revolutionized the process by parameterizing Bridgemeter. This solution allows continuous collection of treatment process data, with real -time graphs of:

• Standardized permeated flow;
• Conduction pressure and driving liquid;
• Percentage of rejection of each skid.

In addition, the Bridgemeter indicates deviations in operation through proactive notifications, maximizing efficiency and reducing the need for chemical agents, resulting in less environmental impact. This continuous and automated approach provides more rigorous and efficient control, ensuring that the system operates within ideal parameters with less manual intervention, improving membrane life.
