Aries Chemical RO and NF Pretreatment Chemicals

Aries Chemical offers pretreatment chemicals for Reverse Osmosis (RO) and Nanofiltration (NF) systems. Aries membrane pretreatment chemicals are designed to protect membranes, improve flux, minimize cleaning and maximize life-span. Aries RO and NF pretreatment chemicals are compatible with polyamide and cellulose acetate membranes. The correct pretreatment chemicals will reduce your operating costs, improve filtrate quality and extend membrane life.

Properly pretreated feedwater is critical for RO and NF system optimum performance. RO and NF membranes can be damaged by oxidizers, mineral scale and other foulants. The damage can lower flux, rejection and recovery rates. The correct pretreatment program is needed to minimize these harmful factors and maximize your system’s performance.

Proper RO and NF pretreatment provides the following benefits:

  • Maximizes flux (filtration rate)
  • Maintains Recovery Rate
  • Minimizes scaling
  • Minimizes fouling
  • Minimizes cleaning
  • Improves membrane life span

Aries Chemical’s Technical Representatives are trained to develop the optimum RO or NF pretreatment program. Aries performs water and deposit analysis to determine the best pretreatment program. Aries can perform system surveys and membrane autopsy to help trouble shoot operating problems.
