Fact Sheet
Hypersperse*
Antiscalants/Antifoulants
The Hypersperse pretreatment program is designed
to significantly reduce scale formation and fouling in
membrane systems. The antiscalants are suitable
and effectively used in a range of feedwater
sources, including brackish, waste and seawater.
The use of GE’s chemistries improves efficacy
against a broad range of scale-forming substances
and keeps fouling material in suspension. Common
foulants and scalants include calcium carbonate,
calcium sulfate, barium sulfate, strontium sulfate,
calcium fluoride, iron, colloidal material, silica and
other organic contaminants.
Hypersperse MDC series offers protection against
scale and colloidal foulants, while the Hypersperse
MSI series offers additional control of silica scale.
Benefits and Features
• Effectively control scales including silica, calcium
carbonate, calcium sulfate, barium sulfate, and
strontium sulfate
• Compatible with the leading reverse osmosis (RO)
and nanofiltration (NF) membranes
• Maintain cleaner membrane surfaces by dis-
persing particulate foulants
• RO systems can be run at higher recovery rates,
which translates to lower operating costs
• Products available with multiple global regulato-
ry approvals
• Non-P products available
• Effective over a wide pH range
• May be fed neat or diluted
• Coagulant compatible products available that
can be used with SoliSep* MPT series products
Description and Use
Hypersperse antiscalants are highly effective liq-
uid products developed to control scale precipi-
tates and reduce particulate fouling within
membrane separation systems.
Excellent results are achieved in membrane sepa-
ration processes including reverse osmosis, nano-
filtration and
electrodialysis reversal (EDR).
Dosing
Typical dosage range is between 0.5 and 4 mg/L.
To determine the adequate dose rate for a certain
system it is recommended to use the Argo Analyz-
er* simulation software. It will provide the appro-
priate application dosage based on the specific
water chemistry and system design.
Argo Analyzer is a tool designed to provide guid-
ance on the best choice of antiscalant treatment
for RO systems. This software is very accurate in
recommending the best Hypersperse product, the
correct dosage and further guidelines for reverse
osmosis systems. It also gives information about
cleaner selection and cleaning procedures.
Please contact your GE Water & Process Technol-
ogies sales representative for details.
