My little piece of peace

Thanks! You too.

 

Hi Hoyt, I do not celebrate that day, but last night in the rugby traditional - "STATE of ORIGIN" - interstate challenge between NSW and Queensland - QUEENSLAND won again for the 7th year in a row... Kneel down Southerners, and acknowledge a superior breed of "warriors" were born of Queensland residing stock...

 

is that the game for people that can't get in the afl.

 

sorry mas, i just can't help stirring, its a vic nsw thing.

 

i am starting work in roma next week on the coal seam so i guess i will be surrounded by nrl people.

 

Hi White,
Not necessarily - it is an Australian thing...... - lots of migrants from Southern States (of desperation?) - well south of Mexico, and even from foreign shores all seeking FIFO fame and fortune - or to survive for a little longer before the global economy collapses...

You will note that I have saved on thread space by deleting my previous post...

Several images to upload

I am advised that this is the first hitch-hiker to hit the water and who am I to quibble - it is history and on the hard at Monteys... - - img_0946.jpg

Don't be fooled by the name - you can install the x64 on an Intel CPU.

You have a rosy memory for how things were. Even with software bloat, if you put your 90s notebook side by side, you'll find the new multicore is much more powerful.

 

A bit slow on the uptake - I blame early onset dementia....... Oh yes 65 bit is one up on all the plebs who bought 64 bit devices

Today was not very significant in some ways... I did not feel I had done much but to summarise the status,
- - Legs are drained and ready to receive their respective 3 litres of automatic gearbox oil each.
- - I have yet to pump out the engine sumps and replenish with new stuff and new filters.
- - The task of fitting the depth transducer has been arranged.
- - I have purchased the 25 x 20 litre fuel containers for delivery on Tuesday

- - I am seeking prices on parts for a RO water-maker - seeking around Au$2000 but we shall see - user assembled using a K'archer pressure device and hardware filters and a feed pump that is "salt-water tolerant... all using mains power as that is a cheaper option...

Market nervousness is greatly worrying me, - as I have yet to buy some 700 litres of diesel fuel and it has recently dropped from Au$1.50 to Au$1.40 per litre - - - where will it go??? The LIBOR fraud in Europe is threatening to contaminate the world with falling dominoes, as many are speculating who are normally in denial that there is anything amiss....

 

Forgive my ignorance masalai, but why cant one build a RO water maker from a simple 3 stage RO filter system bought from a local water equipment supplier - i bought one for filtering town water in my house for $200 and uses the dow corning RO filters, and plumb it into a pressure on demand pump which will deliver +50psi of seawater - these run about $150 from a marine chandlery...

Why does it have to be more complicated than this?



What am i missing here?

 

Gooday cobber. O.K. there 'groper' - I'm next in line here Please - - I'll be needing an effective - Water-maker - soon - - 60 ltrs a day will do me fine. Very little power consumption is a must - - so Please - - tell me how this could be set-up on a sailing yacht.

I live out in the country - inland from Cairns - we have our own water & supply the house with a small water pump when it is required - usually use gravity feed thought - we have 2 x double filters that are .5 micron filters (the 4 filters only cost approx $7.50 each x 3 times a year) - but I don't know if this system would filter out salt from the ocean so that it would be fit to drink - - I do know that I can get much finer filters though - - I'm not sure if I can produce enough electrical power to run a pump though ??? Any ideas please ??? Thanks - ciao, james

 

well, i bought my little RO (reverse osmosis) system from Macracken water in Scott st, Portsmith and cost me $200 brand new. I also know that marine desalinator watermakers are also reverse osmosis units... i honestly cant see why the "marine" units cost so much? The only function it seems they have other than a household reverse osmosis system, is a flushing function... i guess once youve run the unit and filled your tanks, it runs some of the fresh water back through it so the filter is not sitting in salt water whilst its not in use and therefore doesnt contaminate the water with some salt when you start it again next time... they also seem to have water quality monitoring, tank level monitoring and automatic run functions etc which seems small justification for the prices theyre asking...

So i wonder, why not just buy a simple household system, and connect it to an appropriate pressure, small volume, saltwater pump to run water to it. Then rig a simple set of valves to allow you to flush it with the fresh water youve made using the same pump youd use to push the fresh water out the tap in your galley...?

You could automate everything if your handy with wiring a PLC controller with appropriate input sensors and solenoid valves... but id be happy just doing it manually...

 

I am led to believe that the membrane and containment cylinder are usually to clean up domestic water and the membrane cannot handle chlorinated or other chemicals used to treat domestic supplies water if used for sea water purification...

Here we use 5 micron filters to remove any solids and activated carbon filters after that to remove any "sterilising" ingredients like chlorinated or other chemicals introduced to purify the DOMESTIC supply...

On the boat, it is a specialised process requiring the removal of salt and microbic biological stuff found in the oceans - The pumps are used for one to 3 hours a day and daily to ensure no algal growth develops in the salt part of the chamber so it is usually washed with fresh water (that has just been made), which will keep things nice for a day or 2 at the most, otherwise the system must be "pickled" to preserve the membrane, which, in a 40inch size is around $1000, so justifies careful care and maintenance... Most marine use RO devices will have links to recommended maintenance, spare parts to carry and shut-down and start-up procedures...

Do not go by my waffling - dementia is creeping in.....

 

Hi Silver Raven,
I have looked around and the best is a locally assembled http://www.waterwitch.com.au/prod_marine.htm and he services Cairns and is based just north of me (near Gympie)...

I am using a local hardware enterprise to see if they can source the other parts beyond their present stock to cover domestic water and include bits to enable poor boaties to get a reliable water supply...

I am basing my "build" on a K'Archer (or an "el-cheapo") with a bronze pump and a mains power - 800W+ motor that will deliver some 12 to 20 litres/minute at 800psi from a 20 to 60 psi feed from the salt water deck wash pump (also mains powered) the rest of the system is manually controlled... Most of the suitable high pressure cleaning pumps will more than serve the need so long as the pump is bronze or will tolerate salt water at very high pressure (the cheaper ones fitted with cast iron high-pressure pumps will not)...

layout with all options is attached as a jpg image, along with a pdf on operation... If the hardware supplier can find the bits at a competitive rate I will post links mainly for Australian "do-it-your-self-buildersers", as several USA cruisers have done such but freight to Australia more than triples the price of small packages from USA and Europe...
