Thanks for the replies.

Morning Everyone, I have periodontal disease and want to find a good periodontist in Bangkok. Can anyone recommend the best place? I was thinking of trying Bumrungrad? Many thanks.

Errr... No.

Morning Everyone, I had a local company fit a 130" white screen (No doubt some Chinese brand...) but I'm not happy with it. I'm using a high-end Epson projector and want to replace the current screen with something better. My friend in the USA recommends Elite Screens - but I can't find them here. I've contacted many retailers, but none will post this thing to Thailand. There must be members on here with high-end setups? If so, just wondering where you got your projector screen from? TIA.

I'm going to send my filtered water to them again to have it tested to see how it is after the filter process. I've been looking for sterile containers online, but can't find any larger enough to send them 3L. Any idea how I could sterilize water bottles myself and not leave any contamination? Wash them out with pure alcohol and leave in the sun for it to evaporate?

I think it was around 6000 baht. I took the samples myself and sent them express courier. They wanted 3L of water.

I'm going to test it again. I've ordered three inline uv filters for the system to kill bacteria/viruses. One will filter it before it goes in to the "clean water" tank and then two as it goes out to the house. Just to be sure.

Sorry for the late reply, I've been travelling. They didn't respond to my emails. The only way I could contact them was via LINE app. This was their standard test, I didn't ask for any specific testing.

Could you post some details of your filter systems?

In the UK we used Berkey filters for the tap water there to remove fluoride... https://www.berkeywaterfilterseurope.co.uk/berkey-pf-2-fluoride-filters

Thanks again for the reply. For Aeration, I was just going to install a compressor pump in the deep well reservoir tank to pump a load of air bubbles for it, it's not hard to do this, so can't hurt? I'll also add an oxidation tray on the top from the deep well feed, they're easy to make from pipe. ???? So plenty of oxygen in the water.

Thanks for taking the time to reply. I used brand-new water bottles from 7/11 and emptied them out. This is my plan for filtering... For filtering, I'm going to look at building an aeration tank to oxidise the manganese/iron pre filter, then filters/water softeners for the iron/manganese/calcium carbonate, and finally a UV system to kill the bacteria. For drinking an R/O system on the main kitchen tap. Please also note, I make a mistake, the deep well is 190m

How about the arsenic content? That has me worried... I read online that the EPA sets a limit of 0.01 mg/l. The reading from my well is 0.0069 milligram/mL. This seems to be well under the limit? Or have I got my calculations wrong?

Very cool, but I didn't want to take up so much space. I have 4 x 5000L tanks for storing rain water.

Thanks for the feedback. I didn't think the arsenic is high at 0.0069mg/L when it says maximum allowable 0.05mg/L ? I guess I'll need to research this more... I thought you could use PFA-2 filters for fluoride? Anyway, no problem, we certainly won't drink it. How about if we want to use it for showering/washing dishes? How could we treat the water to make it OK for this? I'll try and find out if there is a lab that could test trivalent and hexavalent chromium content. One other thing about our well is the water coming out is hot. The deep well company said they have never seen this before on Samui.
