Herco High Production RO System


The Herco High Production RO System is skid mounted upon a vertical frame. Utilising 3 high quality 4040 membranes housed in sleek fibreglass vessels the system offers permeate flow rates up to 900 litres per hour with an average water recovery figure of 75-80%. The quiet multi-stage centrifugal pump produces a working pressure of 14 bar, to deliver an impressive average rejection rate of 97%.

Why Choose Our Herco High Production RO System?

  • Supplied completely pre-assembled and ready for installation
  • RO Digital control panel with conductivity meter as standard
  • High pressure multi-stage centrifugal pump
  • Both analogue and digital inputs/outputs

These cleverly constructed RO systems are designed with the operator in mind. The RO Digital control panel offers fully automatic monitoring and control of the unit, with a range of pre-programmed features. Allowing for further customisation the control panel has 2 additional programmable analogue inputs (e.g. for flow or level measurement), 3 universal digital inputs,  2 universal analogue outputs and 3 digital valve outputs (e.g. for concentrate flushing or permeate rejection and recirculation). The flexibility of this system makes it a great addition or upgrade to any plant room.

Suitable for a feed water TDS of up to 1000ppm and water temperatures of up to 35°C. As with all RO systems the permeate recovery and rejection figures depend on several factors such as feed water quality, temperature and the type of pre-treatment used. If your water hardness is over 100ppm it would be recommended to install a water softener prior to the system to prolong the life of the RO membranes. If you are feeding the system with chlorinated water then suitable carbon pre-treatment is recommended.

How Often Do I Need To Replace The Filters In The Herco High Production RO System?
The 5 micron pre-filter should be changed when the gauges on the filter housing show a pressure differential of 1.5 bar. The RO membranes should be replaced when you notice a drop in permeate production or quality. With soft water, membranes can last up to 5 years however with extremely hard water (and no pre-treatment) membrane lifespan can be reduced to 12 months or less.
