When you consider purchasing this system, you need to know the following information as it is very important.

This system requires a pretreatment setup for it to perform like it was designed to.

Below, the sketch shows a basic pretreatment setup with the reverse osmosis system.

The above pretreatment setup is not guaranteed to work unless recommended by a sales agent according to the water analysis report from a lab.

A water analysis report is very important as it determines the pretreatment setup needed to be installed before the reverse osmosis system. As you can see on the sketch above, the pretreatment consists of a Sand/Glass Filter, Carbon Filter, and Antiscalant Dosing system.

Pretreatment setups can consist of even more items installed before the reverse osmosis system. Below is a list of items that could be required as per the water analysis report.

  1. Chlorine Dosing System
  2. Ultrafiltration System
  3. Dmi-65 Iron Removal Media Filter System
  4. Ozone Generator
  5. Flocculant System

Once all the equipment has been purchased, you will need a qualified technician to put together the complete setup. We have our own qualified technicians train by the manufacturers of the equipment to do the installation running of the setup. Should you require us to install the system for you, a quote with the installation fee will be sent to you by the sales agent in charge.

Training can also be offered to the guys you want to be the ones installing your setup instead of our technicians.

500 Litres Per Hour Industrial RO System In A Cabinet

Black Cabinet Series Industrial RO Systems are designed to produce low dissolved solids product water from the tap or well water. These systems use a high efficiency, low energy membranes, and run at high recovery offering low maintenance and operational costs. They incorporate carbon filters for chlorine removal, and sediment pre-filtration prior to the RO for a packaged unit that is ready to run out of the box.

Recommended Pre-Treatment Equipment:

All pretreatment equipment and SDI test kits are available from Applied Membranes.

  • Water Softener: Hardness must be removed if present in feed water prior to the RO system to avoid scaling the membranes.
  • Multimedia filter: If feed water exceeds <1 NTU turbidity or silt density index (SDI) of 3, media filter pretreatment recommended.
  • Systems rated at 77°F (25°C) using 1000 ppm sodium chloride solution operating at approx. 200 psi.
  • Capacity Basis: 24 hrs/day
  • Minimum feed pressure to RO System: 40-60 PSI.
  • RO System capacity changes significantly with water temperature

Applications Of The Industrial RO System

  • Spot Free Rinse/Car Wash/Water Stores/Whole House/Hotels Breweries/Restaurants / Laboratories/Large Office/Institutions / Ice Makers/Humidification/Misting / Commercial Manufacturing/Rinse Water / And a wide variety of other applications

* Minimum recovery rate is calculated based on no concentrate recirculation, it is possible to increase the overall recovery rate by increasing the concentrate circulation flow.
** Permeate flow rate can vary depending on the type of membrane, raw water quality, and recovery rate.
