Membrane technology products

Membrane processes are a valuable and highly effective method of removing all kinds of pollutants. They are robust, fully automatized, efficient and have low energy consumption. Our units can be used for final treatment of water from water distribution pipelines, rain water or less polluted surface water. In some cases the technology can even be used without dosing of chemicals, as it consists of a remote monitoring panel, which renders it self-sufficient to the maximum extent. The easy and robust design of the technology is most suitable for remote locations and developing countries.

Ultrafiltration unit

Type:

MDWTP-S

Type of treated water:

Water sources without significant chemical pollutants, possible microbiological pollutants (bacteria), organics; e.g. water from distribution pipeline, rain water, surface water.

Possible deliverable volume:

  • MDWTP-02S: 0.2 m3/h
  • MDWTP-05S: 0.5 m3/h

Description of the technology:

The treatment unit is based on membrane processes. First, suspended solids are removed and organoleptic properties are improved by zeolite and active carbon filters. Subsequently, the water is treated through an ultrafiltration membrane unit. Hygienisation with a UV lamp is the last step to ensure water safety and quality.

 

Removal of:

  • Turbidity
  • Bacteria
  • Viruses
  • Organics
  • Suspended solids

Ultrafiltration unit with pH adjustment

Type:

MDWTP-M

Type of treated water:

Water sources without significant chemical pollutants, possible microbiological pollutants (bacteria), organics; e.g. surface water.

Possible deliverable volume:

  • MDWTP-2M: 2 m3/h
  • MDWTP-6M: 6 m3/h
  • MDWTP-12M: 12 m3/h

Description of the technology:

The treatment unit is based on membrane processes. First, the pH is adjusted, coagulant is dosed and the pollutants in the water interact with each other. Then,  suspended solids and pollutants are removed and organoleptic properties are improved by 130-micron filter and active carbon. Subsequently, the water is treated through an ultrafiltration membrane unit. Hygienisation with a UV lamp or chlorine is the last step to ensure water safety and quality even in the distribution pipeline.

Removal of:

  • Turbidity
  • Bacteria
  • Viruses
  • Organics
  • Suspended solids

Optional additional feature:

Adjustment of organoleptic properties – smell, odour, taste. Removal of pesticide, total water hardness.

Low-pressure reverse osmosis

Type:

MDWTP-Low-pressure

Type of treated water:

Water sources with increased concentrations of heavy metals, calcium, sulphates, suspended solids, bacteria, viruses, organics; e.g. water from distribution pipeline, rain water, surface water.

Possible deliverable volume:

  • MDWTP-Low-pressure: 8 l/h

Description of the technology:

The technology is capable of removing nearly any kind of chemical and biological pollutants.

The low-pressure reverse osmosis unit is based on membrane processes. First, suspended solids are removed and organoleptic properties are improved by zeolite and active carbon filters. Subsequently, the water is treated through a reverse osmosis membrane. Hygienisation with a UV lamp is the last step to ensure water safety and quality. Distribution of treated water is performed by external tap in the sink.

Removal of:

  • Turbidity
  • Bacteria
  • Viruses
  • Organics
  • Suspended solids
  • Heavy metals
  • Sulphates

Parameters:

Water supply Power consumption Dimensions Weight Water consumption 5 l/day Water consumption 100 l/day
8 l/h 55 W 370 x 450 x 200 mm 9.2 kg 38 people 2 people

Water source parameters:

  • Pressure: min 2.2 bar
  • Water temperature:  2 °C – 40 °C
  • Total hardness: max. 170 ppm
  • Free chlorine: max. 0.1 ppm
  • Iron, manganese: max. 0.1 ppm
  • pH: 3–11

Optional additional feature:

Removal of boron, iron, manganese, heavy metals.

Components:

  • Filter 5 micron – Suspended solids are removed on a 5-micron filter, lifetime 6–12 months.
  • GAC filter– chlorine and organic pollutants are removed, protection of the RO membrane, lifetime 6–12 months.
  • Filter 1 micron – small suspended solids and residues of activated carbon are removed on a 1-micron filter, lifetime 6–12 months.
  • RO membrane – the water is treated through a reverse osmosis membrane Vontron 75 GPD, which removes organic pollutants, bacteria, viruses, heavy metals, dissolved ions, etc., lifetime 24 months.
  • Storage tank – compensation for a slow production of water through a RO membrane, 12 liters.
  • GAC and remineralization postfilter – organoleptic properties are improved by the activated carbon postfilter, while remineralisation process returns balanced content of healthy minerals into the water, lifetime 6–12 months.
  • UV lamp – secures water in case of secondary contamination, e.g. from pipeline or tap, 6 W, lifetime 12 months.
  • Pressure pump – additional pressure pump, 24 volts, source 220 V.
