Antiscalants and Antifoulant

King Lee powerful proprietary formulations of antiscalants and antifoulants sets us apart from the crowd. Having been in the membrane chemistries industry for over 40 years, we have formulated the industry most effect chemicals aimed at increasing membrane productivity, decreasing cleaning frequencies and eliminating acidification, all while taking on even the most challenging water applications.

Pretreat Plus® Gypsum Concentrate

A powerfully targeted antiscalant for hard to control calcium-sulfate / gypsum scale.

Pretreat Plus® 0100

The most widely used for all applications, this broad spectrum antiscalant is excellent in controlling calcium carbonate, silica, and iron.

Pretreat Plus® Select

A more cost effective broad spectrum antiscalant for use with RO systems treating water with less scaling potential.

Pretreat Plus® S1000

An antiscalant for feedwater with higher silica scaling potential combined with dispersant properties to inhibit colloidal fouling.

Pretreat Plus® 0100 Concentrate

A concentrated version of our PTP 0100 for overseas shipments and large water treatment plants looking to reduce freight costs and footprint.


A highly effective antifoulant and anticoagulant with broad capabilities for inhabiting silt, organics, colloids and fine particles from fouling the membrane.

Pretreat Plus® Y2K

Our most robust broad spectrum antiscalant having great scale control capacity typically used at a lower dose.


A highly effective antifoulant specially formulated to inhabit colloidal and organic fouling.

NuTreat 1700

A very powerful antiscalant for targeting calcium carbonate and has proven success in post Ro concentrate tanks and lines.
