GENERIC VS. SPECIALTY CLEANERS
Typically, the decision to use generic cleaning chemicals or specialty membrane cleaners is based on raw material cost. However, it is important to consider what you may be sacrificing by not using specialty cleaners. In this article, we will examine the advantages and disadvantages of each type of cleaner, so that you can make an informed decision that is most suitable for your plant.
A reliable specialty chemical company should have the expertise to conduct membrane autopsies and cleaning studies to determine the type of scalant/foulant and the most suitable cleaning procedure. Identifying the specific scalant/foulant can help to make cleanings more effective and reduce the time needed to complete them.
Membranes represent about 10% of the initial cost and up to 25% of the operational cost of a membrane system. Premature replacement of the membranes is very expensive making effective and safe cleanings paramount. With generic cleaners, you must handle the individual chemicals in a safe manner and mix them in a precise ratio.
Exposing the membrane system to a cleaning solution with a pH too high or too low, may cause irreversible membrane damage. Specialty cleaners are buffered to achieve and maintain a target pH to avoid possible membrane damage.
Specialty cleaners are specifically formulated to be compatible with membrane systems and include various components such as dispersants to effectively remove contaminants from the membrane surface. Membrane cleaning is an essential aspect of maintaining the health of a membrane system, and whether you choose to use generic or specialty cleaners, you will ultimately need to use them. When it's time to clean your system, it's worth talking to your preferred specialty chemical supplier to see the cost and value they offer. Specialty cleaners can provide greater effectiveness, as well as improved safety during handling and pH buffering.
