High Flow membranes

Membranes intended for applications requiring relatively high permeate flow, subject to feed conditions and approval.

Quick Summary

The High Flow series is intended for applications where system output is a key consideration. Suitability depends on feed water quality, system design and operating conditions, and is reviewed by the Nimbus team before any model is recommended.

Suitable application

Reviewed for systems with a significant throughput requirement relative to installed area.

Selection conditions

Fit is determined by feed flow, water quality and system configuration.

High Flow Models

The models shown include all Nimbus specifications carrying the HF designation in the approved catalog.

Selecting a water-treatment solution is an engineering and operational process. It begins with the water source, composition, variation over time, required flow, target quality, operating hours, site constraints and maintenance approach. A technology name alone is not sufficient to establish suitability.

Website information is general and is not a quotation, binding specification, fit approval or engineering approval. Scope, equipment, performance and conditions will be determined only after data review and an approved Nimbus proposal.
