Technology

AWAK Technologies offers integrated solutions for portable, miniaturized dialysis systems using an improved, customized sorbent; an innovative and forward-looking dialysis application.

What is a sorbent?

A sorbent is a material that binds another substance or compound to it by a physical and/or chemical reaction. It allows the binding of an extremely thin layer of molecules to its surface by chemical bonds, ionic bonds and complexion.

Sorbent technology regenerates and reconstitutes used dialysis fluid into fresh fluid. This unique feature eliminates the current dialytic dependence on large volumes of continuous water supply and costly water treatment.

Activated Carbon Activated carbon removes organic
uremic metabolites, e.g. creatinine, uric acid and some middle molecules such as β2 microglobulin. Because activated carbon binds these molecules without releasing any counter ligands, it is considered a "pure sorbent".

Hydrous Zirconium Oxide HZO is an anion exchanger adsorbing negatively charged anions such as phosphate and sulfide in exchange for hydroxide. HZO is also an effective adsorbent for metals such as iron, mercury and aluminum. Phosphate Bicarbonate Hydroxide
Zirconium Phosphate ZP adsorbs ammonium and other cations, mainly calcium, magnesium and potassium, replacing them with sodium and hydrogen ions, which, in turn, convert ammonium carbonate into sodium bicarbonate, carbon dioxide and water. Since ZP is the salt of a weak acid, it also acts as a buffer. Ammonia

Immobilized Urease Urease is an enzyme, which converts urea to ammonium carbonate. It is chemically bound to an insoluble support. Urea Ammonia
