About The System
Puritech ECO series systems are part of a family of reverse osmosis units specifically designed for operation with fresh and brackish feed waters having TDS values below 1,500ppm. Customers can access these Models with permeate outputs of between 150 and 1,000 liters/hr as shown in the specifications.
The reverse osmosis systems have been widely used for commercial purposes such as treatment of wastewater, desalination, minerals reclamation, and purification of water. If you have been searching for the best and efficient Industrial RO system, then you have landed at the right place. At Puritech, we provide the best quality of RO water units that can meet your needs, expectations, and budget.
We provide the highest standard and compact commercial reverse osmosis system at an affordable pricing range. All our RO systems are highly durable and we guarantee that they can be last for many years with proper care and maintenance.

4. General Plant Description
4.1 Purpose
To reduce dissolved salt content of raw water for later use.
4.2 Principle Process
Reverse Osmosis (RO) is a form of high pressure hyper filtration where dissolved solids are removed from the supply stream to produce treated water (permeate) and waste water (concentrate). This is a continuous process running at a fixed flow rate.
4.3 Process Flow
Water is fed from a saline supply with minimal suspended matter, i.e. Pre-treated water, to the filter cartridge before being pumped through the reverse osmosis (RO) stage of the system where the dissolved salt content is reduced. The treated water (permeate) is fed into a holding tank and the concentrate to drain.
5. Process Description
5.1 Pre-Filtration
Raw water is fed through a pressurized line into the water treatment system. The filtration stage of the system consists of a cartridge filter in which suspended matter larger than 5 microns is removed. A solenoid valve is used to shut off the supply line when the holding tank has reached its top level or when the system is turned off.
5.2 Reverse Osmosis (RO)
Pre-filtered water is fed to the RO system by means of the horizontal centrifugal pump.
The pump is controlled by the following parameters, namely:
- Product tank high level, indicated by a float level switch
- Raw supply tank low level, indicated by a float level switch.
- Low-pressure condition, indicated by the pressure switch
- Timer unit contact.
The RO system generates two steams of water, a purified stream (permeate) is directed to the product tank while the concentrated stream is directed to the drain. A ballvalve on the concentrate line allows for manual flushing of the RO system. Pressure indicators are fitted at strategic points to illustrate the systems operating pressure. Flow rate through the system can be monitored by the inline rotameters on both the permeate and concentrate lines.
En route to the product tank, permeate passes a conductivity probe, which reads conductivity of the product water
