Hydranautics HYDRAcap 60-LD Membrane

Hydranautics HYDRAcap 60-LD Membrane
Product Description

Compared to conventional pretreatment, HYDRAcap 60-LD 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). In some cases it replaces conventional pretreatment for potable applications, ground water recharging and water recycling.

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
