1812-80G High-Efficiency RO Membrane for Household Water Purification
I.Product Description
Model 1812-80G is a domestic reverse osmosis (RO) membrane element designed with a two-membrane-leaf structure and 11 turns, ensuring efficient water filtration and stable performance. It provides a rated permeate flow of 80 gallons per day (GPD) and achieves a desalination (salt rejection) rate of up to 97%.
With its standard 1812 size, the 1812-80G membrane is suitable for household RO water purification systems, effectively removing dissolved salts, impurities, and contaminants to deliver safe and high-quality drinking water.

Identify needs
Clarify the following issues, and you can determine the right equipment for you.
Water quality problems
Example 1: sediment exceeds the standard/scale / turbid water / microbial exceeds the standard/ heavy metal exceeds the standard/money Yu exceeds the standard, etc.
Water standard
Example 1:Softened water/pure water/ultra-pure water/iron and manganese removal/sediment removal/sterilisation, etc.
Daily Water Consumption
Example 1:Whether there is a concentrated water consumption period/water consumption time/peak maximum water consumption/hourly average water consumption
Conclusion Example
5 tonnes per hour water softening equipment.
3 tonnes per hour reverse osmosis water purification equipment
If you can't answer the above questions clearly?
1. Daily Water Consumption: Mail a bottle of water sample
