Hi Semo Thanks for the tips there , will "digest" the filter info. Water is something we all take for granted. I wish some 15 years ago I had migrated into the water industry along with many others who came across from the Petrochem industry (when it went through a drastic price...

Hi Hydrae Yes I get the idea. A deep well is one that taps below an impermeable layer. I dont think we have any soil like that here, just laterite Hi Semo Its interesting about charcoal and its effectiveness when unactivated. I might try some kind of test. Of course swimming pool water has a...

Hi Hydrae What is your definition of a shallow well as opposed to a deep well? The traditional way here is to use pre-cast concrete rings about 1 metre dia and to dig inside so that the ring gradually fall into the well hole. Very tiring, takes 3 man 3-4 days and its hazardous. the depth is 15...

Hi Semo Our local pond water storage systems use a backwash sand filter. We can make simple sand filters quite readily as river sand is plentiful. Now about charcoal? I have conflicting info on the use of this. Ive heard that using ordinary crushed lumpwood charcoal(ie not farbricated...

Hi Hydrae Thanks for that titbit, most useful. In fact its these custom and practice things that are the most valuable. I am not at all skilled in the arts of chemistry but that paradoxical smell is a good tip. Of course the ammonia thing comes from human bodies I suspect (in swimming pools)...

Hi Dave Oyster shells, that sounds like an excellent idea. We have out here (in the Moon river - 2nd largest in Thailand) a species of freshwater oyster, freely available. I have eaten these, they are a bit chewy, like snails or whelks. The shells can reach palm size. They could certainly be...

Hi Countryman thanks for your input, as you can see from the thread, my simple question has generated some very sound responses. My orignial query was that, when I searched the "alternative technology" type sites I couldnt find an obvious reference to household bleach - which is very...

hy hydrae thanks for the tip, cant get any prices from this site as I have to become a registered user and give all kinds of personal info first. Can you imagine walking into your local store and being asked for such details before you can get to the counter. You would walk straight out again...

Hi Mat Thanks for your input, the advice on filtering is good. Sometimes the obvious is overlooked. WE dont have diatomaceous earth here. Would you suggest using sand and crushed charcoal in a barrel as a filter? I suggested using a small dose of household bleach in the water because its...

Hi Guys I just had to respond to this For some perverse reason I have a collection of victorian books on Sanitary engineering, with some plate of the original designs by Thomas Crapper. These date back to 1880 and include much of Londons sewage system and its redesign form the original lead...

Hi Saxon & Hydrae btw I thought Hydrae was a multi headed serpent from greek mythology, and also some low life pond dweller?? ;-} Yes Saxon, I learnt very quickly in Nigeria always to have a back up plan , and a backup one for that, havbing nearly been totalled twice over there. But I didn...

Hi Guys Im afraid I got a red mist when I read the posting. Not that I criticise the guy for asking an innocent question, thats entirely fair. Its just all the lame answers he mostly got in this forum titled Instrument engineering. I have more than 30 years in the game, man and boy apprentice...

Hi Guys I agree with the radar approach as being the most reliable, but its expensive and maybe an overkill for a daytank on off level. I presume there is some heating jacket to keep the chocolate above 80C? You might consider a set of vertical capacitance probes top entry from the tank roof...

Hi MVD IMHO you really need to spec out your process fully first before the good people here can offer you informed opinions. Apple juice is a new one on me, but then I am petrochem. I am puzzled as to why you need massflow, what is your line size ? presumably because you have a frothy process...

Hi jae The established way to determine water cut is to use and bypass sampler with a capacitance meter, this is quite accurate and is used for custody xfer and fiscal duty. There's a lot of gen out there on pipeline sampling and determination of water cut (BS&W). Have a look out there. btw dont...
