Hi, I have problems with a sand filter / zeolite. change the filter bed two months ago and since then the filter has to count out pseudomonas aeruginosa. try soaking the bed with a solution of calcium hypochlorite and we are waiting for microbiological results. if not improve water quality need...
Good morning,
I have a purified water plant where the final two drives in parallel CEDI which serve to bring the conductivity of 2.5 microsiemens approximately 0.300. I would like to know why there is a difference of amperage on both drives, is this normal? yesterday conducted a chemical...

Good day, I know the reason why I can not use in my system Softening industrial salt with iodine and fluoride?
Currently it is difficult to get into this salt market and in my store there is only edible salt with iodine and fluorine.
I have two days softening salt for human consumption...
Hi, I have a cooling system (evaporative condenser) with the following conditions:
1. The makeup water containing 2 ppm of ortophosphates. (Used as corrosion inhibitor in the pipeline).
2. This water is used to feed a cooling system which uses an alkaline dispersant based on phosphonates...
Hi, i have problems in my wastewater plant:
The pH of effluent is near to 8.0, the pH feed to SBR is near to 6.5 and in the reaction phase have much white foam.
it is possible that the foam must to an excess of coagulant/floculant used in unit CAF, previos to SBR.
Water Analysis are:
Feed...
what is the ideal pH for a feedwater boiler to work 150psig?
* The pH feed is behind 6.8 and 7.5 but in the boiler have pH 11 at 3 cycles. I can have problems in the future??
I feedind NaOH and my feed pH raise 9.2, but is not very high??
sulfites residuals is 30-60 ppm.
Thanks.

Hi, I need to find papers or web pages related with effluent treatment, information such as Treatment theory, SBR, DBO, unitary operations, interpretation of water analysis for waste water. philosophy of plant operator and wastewater laboratory.
im beginning a new job related with this, and my...
Hi, i need to know the effect of operating a firetubes boiler with low level of water (naked tubes).
I can have overheating in the superior tubes o any tipe of corrosion?
Mi sulfide residual in the boiler is 25 ppm.
thanks.
Hi, im writing from venezuela.
I need to know how is posibble that im having scaling in my evaporative condenser if my water feed is:
TDS: 320 ppm
Total Hardness: <10 ppm
pH: 7.2
bicarbonates: 190 ppm
Silice: 29 ppm.
Temp: 77 F.
i work the condenser at 4 cycles max.:
in the basin have:
TDS...
