Our mission is to advance the
reverse osmosis industry by
providing superior products,
services and technical
expertise aimed at increasing
membrane life and
productivity.

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 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.

Products

King Lee’s powerful proprietary formulations of antiscalant & antifoulants sets us apart from the crowd. For over 40 years we have formulated the industry’s most effect pretreatment chemicals. They work to optimize, increase productivity, decrease cleaning frequencies and cut costs, all while taking on even the most challenging water applications.

Antiscalant & antifoulants work differently but all with the same goal, keeping your RO/NF membranes running at maximum productivity. Antifoulants work to prevent organic and biological material, colloids, silt, and other fine particulates from attaching themselves to the membrane. Antiscalant temporarily keeps sparingly soluble salts in solution so they do not stick to the membrane and form scale. There are many different types of scale and foulants which can hinder membrane performance. Depending on your water chemistry, you may need a broad spectrum antiscalant, a specifically targeted antifoulant or a product which provides protection for both.

You may be dealing with brackish ground and surface water, wastewater from reuse applications or seawater. We have the right product to meet your needs so you can keep the water flowing.

King Lee Technologies started manufacturing specialty RO/NF membrane cleaners over 40 years ago. Since then, we have continued to develop effective membrane cleaners used in a wide variety of applications. These include groundwater, surface water, seawater and reuse applications.

Even with effective pretreatment, membranes will eventually begin to scale or foul. Depending on the degree and type of fouling, generic low and high pH cleaners may not fully clean off scale and foulants. Thus, residual residue could act as a hub attracting more scale and foulants resulting in a quicker fouling rates resulting in the need to clean more frequently. King Lee offers a variety of membrane cleaners to meet your specific needs. We offer our KL series powder cleaners for cost effectiveness and Diamite series liquid cleaners for ease of use.

KLT manufactures specialty chemicals in addition to antiscalants and membrane cleaners. These RO/NF specific membrane compatible chemicals work to control bio growth. Microtreat™ BIO loosens bio growth on the membrane surface which can ultimately be removed with a high pH cleaner. Memstor™ is highly effective for short- and long-term membrane preservation with no significant loss in salt rejection upon startup.

We also provide a coagulant, Profloc™ C, which aids in the removal of larger particles by media filters and is compatible with many of our Pretreat Plus line of antiscalants. Our sanitization product, Microclean™ UHP removes free-floating biological organisms in ultra high purity water piping and DI water systems. It’s economical, highly effective and has shorter rinse-up times than similar products containing hydrogen peroxide and peracetic acid such as Minncare.
