Making pure

[Tuffers]

The snow has now turned to ice here /emoticons/sad.png, oil filled radiator is already turned on in my van.

Well you can keep your snow and ice, got decent sized pressure washing job next week, followed by a mansion and outbuildings, and extensions, etc etc guttering job, that I am going to struggle to get done in the day I quoted, snow and ice will kill both.

slippy slush here. Went to the tip today, got soaked and hardly a soul there. Must remember to get waterproof boots!

Watching the pure freedom vid again with the ro filter, it seems easy to understand. The di only, is that a whole lot quicker and the ro is just not needed? Would the ro only not work? How do you know when to change/add the resin? How long will that bag last at 60 tds and say 300L per week?

That's a lot of questions but I couldn't find out from Google or searching the forum history.

I like the idea of keeping it inside for now to avoid the cost of a box and heater and the extra set up

Bah, why does everyone have great water, mines hovers between 450 and 470 out the tap....
Wish I could go DI only /emoticons/sad.png

Mines 330/380. It's a pain. But what can you do.

 

[Smurf]

You can run a ro/di or just di it is up to you as there are pro's & con's for both methods.

Basically the higher your tap tds is using di only the quicker the resin will get exhausted but does not produce waste water and is generally quicker than using a ro. Downside is if you produce high volumes of water with a high tds reading the cost of resin will be shocking.

Alex has just kindly sent me a spreedsheet verion of his di resin calculator

So @Jimroot as a rough guide for instance regarding using di only, tap tds of 60 ppm, using 11ltr di tank of resin to produce 4000 ltr a month will cost approx £33 per month (resin cost at £75 a bag). The resin will need changing approx every 4.4 weeks.

If you want to produce more water or tap ppm goes higher the cost of using di only will obviously goes up.

4000 ltr sounds a lot of water but the average wfp single operator will get through around 300-500 ltrs a day and could be a lot more on bigger commercial jobs.

....But Jimroot said he's only using 300ltr a week...have you got a calc for that Smurf.

 

[Jimroot]

Thanks for that smurf, most helpful. When the tds is above 0 do you replace the entire resin?

I reckon di only to begin with sounds a great idea. I continue to meet people, tell them what the new business is, And they want quotes or have contacts for work, so I need to get cracking on offering this.

I'm going to order the 11l di, gardiner pack and clx 18. Deciding on vac poles is most difficult.

 

[Jimroot]

I reckon allowing for waste, I'm looking at £4 a week?

I might be tempted to pole ground floors maybe, doubling that

 

[Smurf]

60 ppm to produce 300ltr x 4 = 1200 ltr using 11ltr di works out roughly £10 per month. Resin would need changing approx every 14 weeks.

its harder than it looks that grass cutting....but it does keep you busy...and it is a change.../emoticons/biggrin.png

This is one of the areas in which I do actually have some experience of full time mowing with a big petrol push mower, and I agree more than half a day of it, it becomes a pain and hard. But it's also quite fast and could earn

Buy your resin vessel from ebay, there's a guy on there who sells refurbed vessels for around half the price anywhere else....that way you can have two vessels for the price of one for when you start to double DI.

Is it worth getting a hot blower to melt the gutter sludge? My new vac is meant to have a hot blower for that

 

[Jimroot]

Will look him up bingo

....Here's the link to the fella for the vessels....may even do a deal if you buy 2 :thumbsup:....

[Smurf]

I think that's the same chap I got mine from.

 

[Jimroot]

I prefer auctions with a best offer, I test my 'apprentice skills'

 

[Jimroot]

smurf, can I ask you to list all the other little things I will need, like hose, cause I'm running out of time to look it all up. Got to fix a bed, fix a lock, do the washing up vac the house, then wear my son out by half three at the park

 

[Smurf]

I don't have a blower option on the vacs I use but might come in handy I suppose.

If the gutters are likely to be frozen I either reschedule or attempt to clear them by hand.

I've even been known to run hot water through them in the past.

I don't have time myself at the mo as have to go out to do some quotes.
