It is important to check on the level of semi-colloidal suspended solids in the feedwater to RO systems. The level can be estimated (not measured absolutely) by the Silt Density Index or SDI test which measures the blocking rate of a 0.45 micron filter pad under controlled pressure conditions.
The following is a brief narrative describing the intended control strategy between each a Reverse Osmosis (RO) train and the water treatment plant SCADA system.
It describes the control system we will supply and outlines the basic operation of a Reverse Osmosis skid and the required handshaking with the water treatment plant SCADA system. This narrative in no way encompasses all of the responsibilities of the water plant SCADA as we are not familiar with all of the requirements of the end user.
You may be surprised to learn just how much water it takes to grow the food we eat and bring livestock to market. So, just how much water does it take to produce a pound of corn and a pound of beef? Read on to find out!

Membrane systems operating at 82% recovery will convert 82% of the total raw water input into treated permeate, with the remaining 18% being sent to waste as concentrate (or reject). The recovery rate is monitored using flow meters installed in the permeate and concentrate piping.
From IT computer server rooms to automotive factories, improved productivity is a reality thanks to modern automation technologies. Membrane water treatment plant operations can be supervised by the same intelligent controls, easy-to-use human interfaces, and industrial SCADA (Supervisory Control and Data Acquisition) systems that are used in other industries.
Water quality and purification processes have improved greatly over recent years alongside the demand for drinkable water which has also increased. Today’s membrane treatment plants can be tailored to fit specific needs and the membrane treatment methods used can reduce contaminants more than ever before. Where the desired outcome is stable, clean water with an appreciable return on the investment, upgrading to a membrane water treatment system is backed by cutting edge industry science.
