FreeFlow System Antiscalants from Dr. Nähring Water Treatment GmbH

During the filtration process of a reverse osmosis system, the raw water is separated into permeate and concentrate. Depending on the yield, the water constituents in the concentrate are concentrated to a greater or lesser extent. In this process, the solubility limit of one or more compounds may be exceeded. In this case, the addition of antiscalant is necessary, which prevents or hinders and delays the formation of residues.

 

The FreeFlow System offers FreeFlow Antiscalants that are optimally adapted to the requirements depending on the formulation. FreeFlow Antiscalants can also contain more or less phosphor if, for example, low-phosphorus or phosphorus-free antiscalants are required in the case of direct discharge of the concentrate into the receiving water. Dr. Nähring Water Treatment GmbH has various FreeFlow Antiscalants in its portfolio, depending on the requirements:

  • Antiscalant against precipitation of calcium carbonate
  • Antiscalant against precipitation of calcium sulfate
  • Antiscalant against precipitation of barium sulfate
  • Antiscalant against precipitation of strontium sulfate
  • Antiscalant against precipitation of calcium phosphate
  • Antiscalant against precipitation of calcium fluoride

Metals such as iron, aluminum and manganese can also be stabilized by dosing antiscalant. FreeFlow Antiscalants are designed, formulated and manufactured by Dr. Nähring Water Treatment GmbH at the company's facility in Dürnau: FreeFlow System Antiscalants made in Germany.

Mem and Memobrane membrane cleaners from Dr. Nähring Water Treatment GmbH

Cleaning of the membrane with the help of membrane cleaners may nevertheless remain necessary. At a minimum, cleaning is required if there is an increase in pressure, a decrease in permeate volume or an increase in conductivity in the permeate above the level specified by the membrane manufacturer in the membrane system.

Dr. Nähring Water Treatment GmbH has various Mem and Memobrane membrane cleaners in its portfolio, depending on requirements: Solid membrane cleaners of the Mem product line, liquid membrane cleaners of the Memobrane product line.

  • Alkaline cleaners of Mem line are solid membrane cleaners against organic fouling, biofouling, particle fouling, iron fouling and manganese fouling.
  • Acidic cleaners in the Mem line are solid membrane cleaners against mineral fouling and iron fouling.
  • Alkaline Memobrane series cleaners are liquid membrane cleaners against organic fouling, biofouling, particle fouling, iron fouling and manganese fouling.
  • Acidic cleaners in the Memobrane range are liquid membrane cleaners against mineral fouling, scaling and iron fouling.

Mem and Memobrane products for membrane and ultrafiltration systems are designed and formulated by Dr. Nähring Water Treatment GmbH and manufactured at the company's site in Dürnau: Mem and Memobrane membrane cleaners made in Germany.
