Drinking Water Treatement System

Water Treatment

Dear All,

I have read your discussions about so-called under the sink filtration systems and checked y28. The system they sell is based on reverse osmosis. Reverse Osmosis can indeed filter up to virtually any grade, however for real reverse osmosis systems, high pressure is needed and real RO-systems will not only filter harmfull elements, but also essential minerals like calcium and magnesium. I ask myself how well these so-called home RO-systems work.

Personally, from my profession's point of view, I work with microfiltration filters that are suitable for home-use but are also used for professional appliances. Problems with most home water supply are bacteria such as protozoa that cause stomach problems. Although most cities know how to filter water, they cannot control the transport lines from their filtration systems to private homes. Certainly in countries with high temperatures, bacteria multiply themselves and cause problems.

There are now filters available that filter all harmfull bacteria and, next to that, also filter odors, metals and tastes like chlorines (used by municipality to filter water). Such a combined filter can be purchased in The Netherlands for approximately HK$ 700. I don't know if these fliters are also available in Hong Kong. I'm anxious to learn what the market in Hong Kong is about. If I look at yk28 prices, I think the Hong Kong market has great opportunities. Should you like to have more info, please let me know.

Regards,
Sulo Ocak

I only drink tap water, but my wife prefers to boil it for her and my daughter. It's a question of habits. I heard filters are a good place for breeding bacterias. Don't know if true.
I personally think bottled water is a dead water, travelling one month in a container. The local one is distilled, so no idea what's the use of it. Ironing?
I confirm what Loupou says. HK water is drinkable.

The water is safe to drink in HK- but it all depends on the pipes it comes through before it gets to your taps! If the pipes are old, rusty and dirty- well that is going to have some effect on your water.
I've lived in HK for 13 years and always had watsons water delivered, it's just so much easier- we have the mineralised.

I also have Watson mineralised water delivered (it same with a free hot/cold water dispenser!) . Then you know you have clean water (its been distilled first) and it hasn't been sitting around in the pastic bottle for months! The cheap water filters cannot remove heavy metals and pesticides, to remove these you need to get a reverse osmosis system. But reverse osmosis leaves you with distilled water - ie no minerals. So whats the point?

I am VERY SURPRISED to read that a lot of people drank out of the tap! I was born and raised in HK and NEVER drank tap water without first boiling it (with or without water filter)! We've been boiling our drinking water for generations (I know my great grandmother did and my son is definitely drinking boiled water). It never occurred to me that the tap water in HK is safe to drink!
