ELGA Multi-stage Water Purification Plant

ELGA is a market leader in the design and manufacture of water purification systems for use in laboratories, healthcare, electronics, and diagnostic markets. 

A high level of water quality is achieved by this plant and can be detailed by the following stages

Stage 1: Raw water tank:  100 gallons capacity 780mm diameter x 1066 hight using a Grundfos CP2-50 pump powered by a 0.55Kw motor to pump

Stage 2: Elamat ELX3 Water softener used in the removal of calcium, magnesium, and certain other metal cations in hard water. Salt storage/brine storage tank for softener resin regeneration

Stage 3: Pilot RO2 reverse Osmosis unit with automatic flushing rig


  • Manually adjustable concentrate flow and pressure control
  • Separate permeate and concentrate flowmeters
  • Pre-filter complete with inlet and outlet pressure gauges
  • Low and high-pressure switches
  • Illuminated start/stop switches
  • Digital conductivity meter
  • Flushing isolation switch

STage 4: Treated sloping bottom Water Recirculation Tank 450 gallons 1220mm diameter x 1810 high utilizing a Grundfos CO4-80/7N Pump 0.5Kw motor

Stage 5: Filtromat AC3 Carbon Filter


  • Digital time clock
  • Easy read controller with LCD display
  • Lightweight construction
  • Automatic backwash
  • Short backwash time (<30 min)

Stage 6: 2 x C1010 Mixed Bed Ion exchange filter with changeover facility monitored by a resistivity meter.

Stage 7: 1-micron filter with changeover facility

Stage 8: Jobay 714-28M Ultraviolet sterilizer. His unit passes the water through a membrane under pressure in a cross-flow fashion. This provides exceptional water quality, removing up to 99% of impurities.


This Process results in Ultra-pure water which has a resistivity of 18.2 MΩ-cm. At 25° C ultrapure water has a very low conductivity of  0.055 µS/cm.
