The Point Four Pressurized Column is a custom engineered

high-performance gas injection system for high-capacity,

on-demand applications such as intensive fish farming,

bottled drinking water, hothouse/ greenhouse plant

production and waste water management.

Water is side streamed under pressure to the column where it is

highly super saturated with dissolved gas and then returned to

main stream. The system is fully automatic, comprising:

level controller, oxygen and water flowmeters, control valves.

Typical performance data (for oxygenation):
1000 l/min side stream flow rate, 11kg/hr oxygen absorption rate

	Side stream DO	185mg/l @ 60 psig, 15°C.
	Main stream DO	7mg/l increase with less than 4% side stream.

Features and Benefits

• Side stream treatment, less than 5% of total flow treated - low pumping requirements.
• 100% gas utilization - no losses.
• High absorption capacity - packs the most gas possible into a given volume of water.
• Compact, easy to install and operate - ideal for emergency situations.
• Custom Engineered - to meet your specific requirements.
