IdroService - Model TWE-LP Series -Reverse Osmosis Plants
TWE-LP series reverse osmosis plants for brackish water, particularly suitable for the desalination of water with TDS up to 8000 ppm for industrial and civil applications.The TWE-LP series, thanks to the high degree of standardisation, offers an excellent quality / price ratio and low running costs. These are reduced to a minimum through the use of LOW ENERGY membranes for brackish water, which offer high production of permeate (demineralised water) at low pressure operations, reducing costs of energy and power.
The management of the system is fully automated through the ROMINI AQUASTAR electronic programmer that controls the operation of the following utilities:
- pre-feed pump (clean contact only);
- solenoid actuated inlet valve;
- high pressure pump;
- dosing pumps;
- automatic membrane flushing system;
- stop / start system.
One of the outlets is energized when the alarms and locks are functioning, in order to remotely control the operation of the system. In addition, the LCD display continuously shows:
- the totalizer of working hours;
- the value of the conductivity of the water produced; and indicates the causes of shut-down due to:
- a full permeate tank;
- low pressure alarm;
- high pressure alarm;
- high conductivity alarm (permeate);
- pump thermal overload alarm;
- backwash or regeneration of pre-treatment systems;
- Lack of pre-treatment chemicals (e.g. antiscalants).
The standard installation TWE consists of :
- double stage pre-filtration with activated carbon and polypropylene cartridge 5 micron;
- anodized aluminium frame;
- solenoid actuated inlet valve;
- minimum pressure switch (adjustable);
- S.S. AISI 316L rotary vane pump;
- glycerin filled pressure gauge;
- max pressure switch ;
- pressure vessels in PRFV (fiberglass);
- brackish water membranes LOW-ENERGY Dow-Filmtec or Applied Membranes, Made in U.S.A;
- needle valve stainless steel AISI 316;
- electronic programmer AQUASTAR RO-MINI full of conductivity control;
- automatic flushing valve;
- pair of flow meters for flow rate measurement of permeate and concentrate;
- float level switch for permeate storage tank.
Optional dosing pumps for antiscalants and chlorine reducer. The TWE R.O. plants use components tested and certified for use with drinking water.
