Hydranautics HYDRAcap MAX 60 Membrane

Product Description

HYDRAcap MAX 60 technology can, in some cases, replaces conventional pretreatment for potable applications, ground water recharging and water recycling. Compared to conventional pretreatment, HYDRAcap allows for higher fluxes for RO and NF systems while maintaining longer intervals between cleanings. HYDRAcap is used to treat surface water, ground water, seawater and waste waters as either primary treament or as pretreatment to reverse osmosis (RO) and nanofiltration (NF).

Capillary Technology vs. Conventional Pretreatment

Significantly better filtrate quality when compared to conventional pretreatment, exhibiting 100% removal of colloidal material.
Product quality is stable even during feedwater vibrations
Single-step treatment reduces operating costs and increases efficiency
Can significantly reduce use of pretreatment chemicals
Backwash disposal is less problematic
Increased efficiency of RO membrane system design and operation, contributing to reduced capital and operational cost
Maximizes RO performance by allowing elements to operate longer with less cleaning
Low pressure operation
