MEMBRANE SEPARATION

Ahura Aqua brings 27 years of experience designing and manufacturing reverse osmosis systems across pharmaceutical purified & ultra-pure water (API, WFI, Formulations), wastewater recovery & reuse, textile & polyester, pulp & paper and chrome-plating for the automobile industry.

RO membranes are the pinnacle of membrane separation — a high-salt solution is forced through a semi-permeable membrane under high pressure. Contaminating ions concentrate into the reject stream while ultra-pure permeate is delivered for commercial, industrial and municipal use.

THE RO ADVANTAGE • THE PINNACLE OF SEPARATION

Tightest Cut-Off, Widest Duty

WORKING PRINCIPLE

A robust pre-treatment stage protects the membrane and sustains rejection — RO delivers maximum efficiency only under optimum operating conditions.

RO SYSTEM CONFIGURATIONS

BOREWELL • MUNICIPAL • PROCESS FEED

The workhorse configuration — low-to-moderate salinity feed from borewell or municipal sources reduced to high-quality process or potable water.

Brackish Water RO

BOREWELL • MUNICIPAL • PROCESS FEED

The workhorse configuration — low-to-moderate salinity feed from borewell or municipal sources reduced to high-quality process or potable water.

FEED TDS

1,000–10,000 ppm

MEMBRANE Ø

4" or 8"

OPERATING PRESSURE

150–400 psi

RECOVERY

70–80%

CONTROL

Microprocessor / PLC

Sea Water RO

COASTAL • ISLAND • DESALINATION

High-pressure desalination for coastal and offshore duties, with energy-recovery devices that reclaim pressure energy from the reject stream.

FEED TDS

up to 45,000 ppm

MEMBRANE Ø

8"

OPERATING PRESSURE

up to 1,200 psi

RECOVERY

35–45%

ENERGY RECOVERY

Integrated ERD

Multi-Stage Wastewater Recovery RO

REUSE • ZLD-READY

Staged RO arrays push recovery toward Zero Liquid Discharge — treated effluent is recovered for reuse while concentrated reject is handed off to thermal evaporation.
