Pretreat Plus® Select

RO and NF Antiscalant

Pretreat Plus® – Select is offered for selected RO/NF feedwater qualities. Equal or enhanced performance guaranteed when normalized data trend charts are used. It is effective over a wide range of concentrations, and does not flocculate dissolved polymers and colloids. Use of this product is recommended for reducing the operating and capital costs of reverse osmosis (RO), nanofiltration (NF) and ultrafiltration (UF) systems. It is especially suitable for seawater and natural Florida waters.

Advantages to using Pretreat Plus® – Select

  • Economy from using active molecules of lowest molecular weights
  • Higher molar concentrations than usual polymeric antiscalants
  • Effective in retarding polymerization and precipitation of silica
  • Effectively controls inorganic scales over a large concentration range
  • Certified under ANSI/NSF Standard 60 for drinking water production.
  • Compatible with major manufacturer’s RO, NF, and UF membranes
  • Does not flocculate dissolved iron/aluminum oxide/silica complexes
  • Effective in controlling calcium carbonate and calcium sulfate scales
  • Effective in feedwaters with pH range 3.0 – 13.0
  • More effective and biodegradable than polyacrylate antiscalants

Data Sheets

Product Info Sheet Safety Data Sheet
Pretreat Plus® Select

Specification: Liquid

Appearance: pH: Specific Gravity:
Clear, colorless 2.0 maximum 1.02

Application:

Pretreat Plus® – Select should be injected into the feedstream prior to the static mixer and cartridge filter. Effective pH range is 3 –13. If frozen, may be thawed and mixed before use. Stability is
excellent, but best used within 12 months.

Dosing Recommendations:

In the useful dosage range of 1 –15 mg/L (neat), control of a wide range of inorganic scales at up to 100 x saturation values or higher is possible. By monitoring the concentrate stream and trend charts, optimal dosage can be achieved for the control of scales including that from calcium carbonate, calcium sulfate, barium sulfate, strontium sulfate, iron hydroxide, aluminum hydroxide and silica.
