K Series  RO Water Filtration System Industry Filter System


Model: K Series

  • Industrial Reverse Osmosis System
  • K series Reverse Osmosis System (Basic RO System)
  • Made in Taiwan


ROTEK compact commercial reverse osmosis system is a durable piece of equipment which, with proper care and maintenance will last for many years. PK series systems are part of a family of reverse osmosis units designed with pre-filtration systems on a skid frame, for operation with fresh and brackish feedwaters having TDS values below 2,000ppm. Models are available with permeate outputs of between 250 and 1000 litres/hr as shown in the specifications tables.

Product Features:
 

  • 304 grade stainless steel perimeter frame with rubber isolation feet.

  • Integrated microprocessor based controller with display for TDS and system status.

  • Automatic membrane flush (with feed water) at start-up and every 12 hours continuous    operation.

  • Flow meters for permeate (treated product) and reject (waste) streams.

  • Liquid filled pressure gauges for feed water pressure and membrane discharge pressure.

  • Feed water inlet cartridge filter.

  • Feed water inlet solenoid valve.

  • Low feed water pressure sensor with automatic shutdown.

  • High pressure UPVC SCH80 membrane pressure vessels.

  • All pre-treatment systems are amounted in one skid frame.

  • Compact Space Saving Design.

Feed water quality, pressures and flow rates have a significant impact on the performance of any reverse osmosis system. To ensure reliable and consistent long-term performance, it is important to supply feed water having the minimum specifications detailed below. If your feed water supply is marginal, you should consider using a feed water break tank and booster pump to supply the system.
