RO pretreatment

Sports fields & turf: improves aeration

Gum/soap removal: reduces phospholipids and residual soaps to improve stability and yield

making them ideal for advanced gas purification and separation processes

Pretreatment before bleaching: used ahead of activated clay to improve overall contaminant removal in challenging crude oils

SILIPORITE® NK 20 AP – 5A Molecular Sieve Powder (Arkema) Drip Pan Absorbent RO pretreatmentOverview SILIPORITE NK20 AP by Arkema is a synthetic zeolite type A in **CalciumSodium aluminosilicate** form. With an effective pore opening of ~5 angstroms (5 ), it's ideal for water adsorption and selective capture of low molecular weight organics (VOCs). Engineered as a low density powder, it integrates easily into formulations to enhance moisture and VOC control. Where it fits Applications Non foam polyurethane systems: helps prevent gassing,
