Please refer to this video on how to do a backwash: ģ. But don’t you worry, you can just do a backwash to restore clean water. After water supply is restored, the water may appear brown or coloured. When water disruption occurs, remember to always turn off Valve 2.Ģ. When the water tank becomes empty during water disruption, incoming water that arrives after the water supply is restored will stir up these sediments and mix them with water, causing water to be cloudy or brown right after a water disruption.ġ. There are always sediments that are settled at the bottom of the water tank.

We do provide polishing services to remove these stains. If there is no presence of chloride, then the “rust” may be stains on the body of the filter, instead of the body itself rusting. Solutions with as little as 25ppm of sodium chloride (salt) can begin to have a corrosive effect. Chloride ions can create localized areas of corrosion, called “pitting”, which can spread beneath protective chromium barriers to compromise internal structures. However, SUS304 does have one weakness: it can be open to corrosion from chloride solutions or saline (salty) environments like the sea. It is also common in buildings, decorations, and site furnishings.

This durability makes SUS304 easy to sanitize, and therefore ideal for kitchen and food applications. SUS304 can resist corrosion from most oxidizing acids. It contains between 16-24% chromium (key element in making metal rust-resistant), and up to 35% nickel, as well as small amounts of carbon and manganese. If the water consumption in a household is high, you should not go for a smaller filter size because it will get dirty very fast and the water pressure may get affected if the household consumption rate is high.ĮR-series filters use SUS304 stainless steel, which is rust-resistant.

Remember, you can opt to upgrade – but not downgrade.

and the water quality of your area’s municipal treated water source (housing area with poor quality water sources require higher filtration performance).

the size of your home (the ER28M is the recommended size for a bungalow),.

how much water you use (more water usage = more volume needed),.

Of course, this also depends on several other factors, like: Naturally, the bigger the filter vessel volume, the better the performance of the filtration process, too. The ER-Series filter is specially designed with a specific height and width so that the flow of water has sufficient contact time with the filtration media layers to get the best absorption and filtration of the water.ĮR19M (Basic): 3 – 5 pax in an intermediate home (single or double storey) 48 LitresĮR19S/SM (Standard): 5 – 7 pax in an intermediate home or Semi-D 66 LitresĮR28S/M (Premium): 7 pax and above in a Semi-D or bungalow 130 Litres The theory is simple, the higher the filter vessel volume in the water filter, the cleaner the water, because there is more space for the filtration process to take place in the tank. We would prefer to have membrane filters as indoor filters (point-of-use), after filtration at the point-of-entry by a MMF outdoor filter, so that the flow rate is not affected too much. For outdoor filters, where the water source can contain more impurities, carbon and anthracite are better materials to absorb chemicals like chlorine. Membrane filters are best used to filter particles and impurities, but not chemicals.

The maintenance and servicing for membrane filters is more frequent due to the reasons above, compared to only one time servicing every 5 years for MMF filters.Ĥ. These may get clogged and cause a lower flow rate in a membrane filter due to it being more fine. As such, there may be more sediments and small matters to filter. Outdoor filters filter water that are directly from our municipal source. The flow rate for MMF filters is higher compared to membrane.Ģ. Outdoor filters require a higher flow rate to provide filtered water for all the taps in the entire home. outdoor filters), we prefer MMF filters compared to membrane. Both membrane filters and Multi-media filters (MMF) like this one, with carbon + anthracite + quartz sand & stones, can work well to provide clean, filtered water.
