Year Founded:

King Lee Technologies created the membrane chemistry industry. Founded in 1977 by Craig Netwig, we have been working with system operators, OEMs, and consulting engineering firms for over 40 years.

We have been working with system operators, OEMs, and consulting engineering firms for over 40 years. We have seen the industry grow from a scientific curiosity to main stream technology producing trillions of gallons of potable water every day.

As membrane technology evolved and grew, King Lee Technologies has stayed ahead of the trend by developing some of the most effective antiscalants, membrane cleaners and specialty products that have enabled clients to meet each year’s latest challenge of increasing product recoveries, extending the time between cleaning cycles, and using more and more challenging feed water.

King Lee Technologies’ staff is always current with latest membrane technology innovations and we have treated thousands of brackish ground, surface and seawater chemistries in our decades of experience. Our uniquely specialized focus in reverse osmosis chemistry, coupled with having the most years of industry experience, truly sets us apart.

It was a young 8-year-old boy’s fascination and curiosity with his Porter Chemistry Set which provided the inspiration for King Lee Technologies. Later, it was his continued curiosity, entrepreneurial spirit and vision which laid the foundation for our company’s culture and what we have become today.
