Tua Engineering - EKO 10 - TPRO Reverse Osmosis - Brochure

DATA SHEET - TPRO Reverse Osmosis Models EKO 10-50 m3/day System Capacities The system capacities indicated below are based on feed water with a total dissolved solid (TDS) content of <1500mg/l and a recovery of 60 to 70%. Model Nominal Capacity Lt/hr Membranes 4” x 40 EKO12 500 2 EKO20 800 3 EKO25 1040 4 EKO30 1200 5 EKO40 1650 6 EKO50 2000 8 Capacity will vary according to the feed water TDS and temperature and pump-operating pressure will vary according to the feed water quality. Typically pump pressure will be in the range of 12 to 17 Bar.

This material is not compatible with oxidizing agents such as chlorine normally found in tap water. The passages within a membrane are fairly small and un-dissolved materials can become lodged inside the membrane blocking it and reducing its capacity. Our systems come with an in-built safety carbon block filter but pre-treatment in the form of further carbon filtration and un-dissolved solid removal is normally required. The reject from a reverse osmosis system has an increased concentration of salts and particularly hardness salts. Care must be administered to make sure that these salts do not precipitate in the membrane as this can lead to irreversible damage. Depending on the feed water as well as the system recovery, a water softener or anti-scalant chemical injection may be required before the system as part of the pre-treatment. Contact your water treatment specialist for assistance on your pre-treatment requirement. System Capacities Operating conditions Equipment Pre-treatment
