Using Flocon

Membrane Chemicals

Using FLOCON^Ž 135 And FLOCON^Ž 260

Dose rate and method

The amount of Flocon required to inhibit scale formation depends on the degree of supersaturation of the insoluble salts at the point of highest concentration in the system. the degree of supersaturation in turn depends on the concentration of the ionic species in the feedwater, the overall salinity of the feed, the temperature of the feedwater, the percentage of the feedwater recovered as permeate and the type of membrane used for the application.

*FLOCON Solution Concentration %**	Amount of Solution to be Injected Per 1000 Gals of Feed, Gals
*FLOCON Solution Concentration %**	3 PPM	5 PPM
100	0.003	0.005
50	0.006	0.010
20	0.015	0.025
10	0.030	0.050

* Use soft water or RO permeate to mix with Flocon.

Dosing method

Flocon should be added to a membrane system prior to the final cartridge filer. If media filtration or activated carbon is used, Flocon should be applied after these treatment stages.

Flocon should be delivered by dosing pump from a dilution tank, direct from the drum or from a bulk storage facility, into the feedwater at a rate that is determined by the size of the membrane system, the recommended dose rate and the delivery range of the dosing pump. It is recommended that the dosing pump be adjusted by stroke length, while maintaining stroke frequency at s high a level as possible to achieve even distribution of the Flocon in the membrane system feedwater.

Caution:

Biological activity
Flocon contains a preservative that is effective up to a dilution of 1 part Flocon to 15 parts of system permeate water. General periodic cleaning of the dosing system is recommended as part of the planned maintenance program.
