HS-200 Liquid Phase, Pure Organoclay

Hydrosil’s HS-200 is designed to remove oil, heavy metals, and similar organics from water. The HS-200 series can remove 70% plus of its own weight in hydrocarbons; Therefore, its’ life inside a still bed is much longer than that of other filtration media such as granular activated carbon. The HS-200 series:

  • Does not swell upon water exposure;
  • Has more active ingredients per cubic foot than other organoclays;
  • Is cost effective and environmentally sound technology;
  • Does not support biological growth;
  • Can be custom blended; and
  • Prolongs life of activated carbon and resins thereby reducing costs and increasing efficiency.

Industries that use the HS-200 vary from environmental service companies to wastewater treatment facilities. The HS-200 is commonly used in oil water separators, frac tanks, pump and treat systems, condensate systems, stormwater run-offs, excavation and de-watering projects.

What is Organoclay?

Organoclay, also known as HS-200, is a sorbent media which is designed to remove organic components. The media is a naturally occurring mineral (commonly zeolite or bentonite clay) which is chemically alternated to create a unique surface on the mineral. The modified surface is designed to create a strong affinity with organic compounds, meaning the media is organophilic. The surface of the media forms a surfactant bilayer which attracts ionic species. Ionic species are components that in solution are grouped as either anionic (anions) or cationic (cations). Anions have a negative charge and cations have a positive charge. The HS-200 has a high cation exchange capacity. The most common cations include ammonia, sodium, calcium, potassium, and magnesium, many of which are desirable in numerous biological and industrial processes.
