Basic Compact Industrial Reverse Osmosis System

 

The Compact Industrial Reverse Osmosis (RO) System is a basic and economical for capacities ranging from 250lts/hr to 500lts/hr for low TDS feed water design Feed TDS <1500ppm.

 

There are two sizes of the Basic Compact Industrial RO Systems available a 250 Litre Per Hour, and a 500 Litre Per Hour. Please note that these are special order products, and so lead time on the RO plants is typically 2 to 3 working days before they will be ready for collection or delivery.  

 

Important: Please note that we strongly recommend having your source water tested, before purchasing any type of industrial Reverse Osmosis (RO) system. As the quality of the source water will directly affect the production rate of the RO system, the Life Span of the filters, the quality of product water produced, as well as the effectiveness of the RO system against potential contaminants in the source water. Filtershop cannot offer any kind of guarantee on the effectiveness of the RO system if no source water test results are supplied before purchasing the RO plant.

Things to Keep In Mind about RO Systems

 

RO Plant flow ratings

  • The production rating of all the RO plants is based on an ideal quality source water, so in situations, with low to poor quality source water the actual flow rate produced by an RO plant can be as low as 30 to 70 % of the rated Maximum capacity. So, in other words, a 100 Litre Per Hour plant typically will produce between 30 to 80 liters per hours in real-world applications.
  • Please also note that during flushing procedures the RO plant will require 3 times the rated output of the RO from the source. (For example, a 100 liter per RO plant will require a minimum flow rate of 300 Litres per hour from the source).
  • Keep in mind that none of the RO plants are designed to be or should be run 24 hours a day, as this will lead to damage of both the components and membranes.
  • The RO plants require a minimum of 2 – 3 bar pressure from the source water, if you are using gravity feed then you should consider putting a pressure pump In to feed the RO system.

 

Waste Water

  • As the RO process filters water to such a fine level, the membranes need to flush themselves as they run to remove the contaminants and minerals caught on them. This flushing results in wastewater, which will go straight down the drain.
  • On the smaller size industrial RO plants, the wastewater to product water ratio is typically between 1:1 and 2:1. So for every 1 Litre produced by the reverse Osmosis plant between 1 to 2 liters will be used to flush the membranes and goes down the drain.
  • With the large-scale RO plants, the wastewater to product water is typically between 1:2 and 1:1. So for every 1 liter of product water produced by the plant between .5 to 1 liter of water is used to flush the membranes and goes down the drain.
  • Please keep in mind that the exact wastewater to product water ratio will depend on a number of factors such as the quality of the source water and what quality of product water you are trying to produce. Normally the lower the TDS you are trying to produce from the RO plant, the high the waste water ratio will be.
  • The RO Plant requires a minimum of 2 bar incoming water pressure.

 

Product water quality

Typically with most municipal supplies, the Industrial RO plants should produce a product water with a TDS of less 10. However,  please note that this will depend on the quality and TDS of the source water. Higher source water TDS will lead to a much higher TDS level in the final product water.

 

Pre-filtration Options 

All RO plants require some form of pre-filtration before the system to both protect the components and to extend the lifespan of the RO Membrane. The type of Pre-filters to put in place will typically depend on the quality of the source water which will be used, which is another reason we would recommend getting your source water tested first before purchasing an RO plant. 

 

Big Blue System Pre-Filter Options 

There are several different Filter Set Arrangements which can be used with the big blue systems, including: 

For more information on these big blue options, please click the above links.

 

Water Softener 

If your source water has a large amount of Lime (Hardness / Kalk), present then we would recommend placing a Water Softener before the RO plant. 

The Water Softener will remove the Calcium and Magnesium (Lime) from the water before it reaches the RO plant. Helping to protect the components, and extending the lifespan of the RO Membrane.

You can find more information on the water Softener Units at the following Link, http://filtershop.co.za/water-softeners

 

 

 

Stainless Steel UV Light 

If your source water has a high level of bacteria in it then we would recommend both selecting a big blue system with the 0.1 Micron Pleated Filters, followed by a stainless steel Germicidal Ultra Violet (UV) Light to further reduce the bacterial content in the water. 

Reducing the Bacterial Content will help to prevent "Bio-fouling" on the RO membranes, and so extend their lifespan. 

You can find more information on the HC-720 Stainless Steel UV Light at the following Link, http://filtershop.co.za/40-watt-2700lph-uv-light-hc-720 

 

Coarse Sediment Filtration 

While the Sediment Filters in the Big Blue System will remove dirt, particles, rust, and other visible sediments, if there is a high level present in the water then you'll find that the filters will block up quickly and need to be replaced very frequently. To extend the life spans of the big blue sediment filters you can place a washable or back washable coarse filter system first. There are two options available 2" Arkal Disc Filter or 100L AFM Glass Media Vessel. You can find more information on both of these options at the following links:
