ARROW®

ARROW® is a high recovery membrane based process for water treatment and recovery / recycling of wastewaters.

The process deploys single-stage and double-stage RO membrane treatment steps with proven, customized, innovative pretreatment, softening, and filtration steps to achieve up to 99% purified water recovery.

The process treats and purifies influent raw water (e.g. from high-hardness and high-silica aquifers) and recovers 95% - 99% of pure RO permeate as the end product.

ARROW® can also be retrofitted to treat refects (i.e. concentrate) from existing RO plants, thus recovering and reusing 80% - 90% of the reject stream.

Product water purity typical of RO permeate (I.e. > 95% reduction of total dissolved solids, TDS).  Ultrapure water quality for the electronics industry, pharmaceuticals, and power generation can be achieved with additional RO and IX polishing.

By using RO membranes to achieve close to 100% water recovery, ARROW® achieves
