The type of antiscalant required depends greatly on your unique feedwater chemistry and system design. When trying to figure out which chemical to use, we can help you determine this with a water chemistry/quality analysis which you can submit via this worksheet to us at [email protected] and we will run a scale projection for you.

Figuring out how much antiscalant to dose requires a scale projection software custom made for each chemical manufacturer. If you submit your water chemistry/quality analysis via this worksheet to us at [email protected], we will run a scale projection for you.

The dosing pump setting depend on a few factors including: feed flow to the system, size of your antiscalant dosing pump, antiscalant concentration in the day tank, and the desired antiscalant dosage. Please check out our dosage calculator for assistance, or feel free to contact our technical support department directly.

The type of specialty cleaner required depends greatly on your unique feedwater chemistry and system design. The best approach to cleaning a system is determining where the problem lies, and understanding how these symptoms relate to foulant or scale composition. Cleaning is a science, which is fine tuned through experience. In general, we suggest applying a high pH cleaner, followed by a low pH cleaner to restore system performance. We have products for all membrane based systems.

In general, we suggest applying a high pH cleaner, followed by a low pH cleaner to restore system performance. Since most membrane systems are uniquely designed, we provide general cleaning procedures at the following on our site “Brochure Library”, but please contact our technical support department for procedures specific to your plant. For chemical dilution procedures, please follow this link to our CIP calculator.

Product Information Sheets can be accessed “Brochure Library”. Please contact us for access to specific SDS sheets.

It can be, but not necessarily, and it is fairly uncommon. Cleaning varies greatly between systems and depends on your feed water quality.

Knowing when to clean depends on your normalized flow or normalized differential pressure. Cleaning should happen around a 15% decrease of normalized flow from your baseline value on your membranes. You can contact us to learn more.

Both over dosing and under dosing can cause scale on your membranes. The best way to tell if you are dosing the correct amount is to double check with a scale projection. You can fill out and submit a water chemistry/quality analysis worksheet to us at [email protected] If everything seems right but you are still unsure what is causing scaling, you may want to contact us to submit membranes for an autopsy.

The Membrane Autopsy provides the advantage of identifying any potential problems before they become unmanageable. However, in most cases, a membrane autopsy is only performed when a membrane is failing or underperforming. A noticeable loss in flow, permeate quality or visible fouling on the membrane itself would indicate a problem with the element and the need to have it inspect.
