Primescreen® is a self-cleaning conical disk filtration system which provides the benefits of primary clarification in a fraction of the traditional footprint and civil cost.
The installation of Primescreen®, thanks to its innovative technology, allows the plant to obtain immediate energy savings due to the reduction of Total Suspended Solids, BOD and COD, decreasing the aeration requirements in the processes after the primary treatment.
Primescreen®is designed to utilize the actual solids being removed to form a filter cake between the disks which serves to prefilter the water before ever reaching the disk surface, and the adherent
properties of this filter cake is used to clean the disks as they rotate and tumble the filtered solids.
The result is filter which eliminates the need for frequent backwashing, reducing the system complexity, lowering energy demand, and resulting in an extremely simple system to operate and maintain.
Even if you have an existing primary clarifier, Primescreen® can allow you to repurpose the existing basins for additional treatment, which can allow you to update your plant for biological nutrient removal or enhance your existing process within the existing footprint.
