Please your help is highly appreciated I have ice bank with 64m3 water by volume how much Kw i can get from it at 1/6 degree.C . and how much Kw i need for it if i use Glycol 33% at -7/-3 degree.C

with mentioned recorded humidity above is it possible to reduce the humidity without dehumidifier only by AC

for the calculation i will hire HVAC company but i'd like to understand the process and the right solution please what is best to use rooftop units or chiller with AHU's your explanation and advice are highly appreciated

this is packaging warehouse where used to store the CARTONS that we use it for milk and to get good sealing we should store it in temperature between 21 to 27 degree.C and RH between 30% to 40% for five days(this requirement from carton supplier) from 2016 monitoring we note the RH above the...

the air inside the warehouse is not conditioned

Ambient temperature (Summer) 45 °C Relative Humidity (All the year) 70%

The maximum humidity and Temperature recorded inside this mentioned warehouse during 2016 70% and 30 degree.C respectively

Please what is the best solution to keep humidity and temperature in warehouse 30-40%;21-27degree.C Area = 1500m2

Please find below water analysis of deep well: Turbidity: 0.53 FNU TDS: 3840 mg/L pH: 6.57 Iron 0.05 Conductivity 7180 us/cm Sulfide Content 3490 ug/L And The Sulfide Content after pretreatment 7 ug/L

we changed our exist sand filters to two stage but nothing change SDI still high around 6

thank you bimr, if we assume the problem coming from hydrogen sulfide please what is the best treatment for that? Because as previous post from ashtree it seems not iron problem from cartridge filters color

in fact coagulant dosing after static mixer (this is the design from the water treatment company)the static mixer after compressed air injection

we inject compressed air (19 l/min) before each the three sand filter units( please see attached drawing you will see the raw water coming from tank T10.10 and T10.20 injected by compressed air then we have static mixer then coagulant dosing) we collect deep well water in buffer tank which far...

So are you saying that you currently have aeration before your media filters? yes pH 7.28 @ 38degree.C for our raw water before injection of air If H2S is a problem it might be easier to use a packed tower degasser to strip off the H2S but it does depend on the raw water chemistry. What we...

may be the Online oxidation of H2S by injection of air before sand filters not enough and we have to add a chlorine oxidation. what do you think? please
