THE NEI SOLUTION:
INFINI-D™
The centrepiece of the NEI solution is the infini-D™ Zero-Downtime Cloth Disk Filter, a revolutionary improvement on the tried-and-true pile cloth disk filter.
Why a disk filter? Disk filters have a small footprint and can be installed into purpose-built or existing steel or concrete tanks.
Why a pile cloth disk filter? Pile cloth disk filters offer high effluent quality from easy-to-maintain disks. No fixed pore-sizes means the risk of fouling is reduced, and the cloth enables an outside-in flow that permits low-backwash vacuum-based cleaning.
Why the infini-D™ Zero-Downtime Cloth Disk Filter? Our infini-D system includes a patented individual effluent port on each disk, enabling disk effluent to be isolated and each disk to be separately inspected, maintained and/or replaced, all without dewatering and while the rest of the disks remain in operation and the entire system remaining online. This built-in redundancy minimizes downtime and the need for backup filtration systems.
