I have very high silicates in my tank as per my icp and coming out of my ro unit, so I have been on the lookout for something to filter the silicates with my ro unit before it gets to the tank.
I was reading a thread on UR and Omotics have hopefully come up with a answer.
It’s a different type of resin that targets silicates, it’s placed after the di pod so it’s not a replacement for standard mixed bed resin but a addition.
The white canister already loaded was £20.41 plus delivery and if going by the product stats it’s a no brainer.
I will hopefully get it hooked up and a icp sent Monday to see what happens.
Below are the stats from osmotics
According to my calculations, with a silicate feed of 500ug/l the cartridge will remove 100% of silicates in 2367 litres of RO/DI water. Remember that your silicate level in RODI should be much lower than 500ug/l anyway so the life expectancy will be correspondingly higher. The calculations are based on our 600ml cartridges. If we end up supplying larger cartridges then capacity will be higher again.
Note that this calculation is based on NO OTHER contaminants being present in the water hence running the cartridge post RO/DI and ensuring a maximum flow rate of 3.8lpm. I recommend running at much slower rates which would be expected in most RO units to ensure the residence time in the resin is maximised to remove silica contaminants.
Applying different feed values gives the following capacities.
100ug/l = 11800litres
200ug/l = 5917litres
300ug/l = 3945litres
400ug/l = 2958litres
500ug/l = 2367litres
These are based on manufacturers data under lab conditions.
