Combi - Shelter
The system is designed to treat bacteriologically and organoleptically polluted water, with an average salinity of 1.500 – 2.000 TDS.
Low pressure reverse osmosis system membranes are able to filter all bacteria and to remove about 75/85% of salinity. Low output membranes are used as they do not require specific chemical products for pre-treatment, such as antiscalants which are not often easily found in areas with few commercial outlets.
Given that this plant is projected to treat medium salinity water, except BRACKISH WATER, we intentionally chose a low pressure process which DOES NOT REQUIRE any REMINERALISATION process, because of its capacity to reject high levels of salts.
Sea water feed IS EXCLUDED.

ADDUCTION PUMP
Submersible, independent adduction pump, to be connected to the inlet by a flexible pipe. The pump has a particular type of impeller which allows small solid bodies to pass, it is totally stainless steel and has a water level gauge which stops the functioning in case of lack of water. 380 V feed.

PRETREATMENT
The COMBI SHELTER is equipped with a TRIPLE FILTRATION SYSTEM, and every stage is dimensioned for a flow rate double that required for actual functioning Thus guaranteeing a long smooth working life.
The process is structured as follows:
  • PRE-FILTRATION
  • SAND FILTRATION
  • CARTRIDGE FILTRATION
PRESSURE PUMP
This pump is a standard multistage vertical axis centrifuge pump with stainless steel body and impellers and a 380 V, 50 Hz engine. Double shaft support guarantees a long working life.

MEMBRANES
High standard membranes, 4”x40” “low energy” type, with a low obstruction surface. These membranes DO NOT NEED ADDITIONAL CHEMICAL PRODUCTS.

VESSELS
Made of fibreglass, using the “filament winding” technique, specific for drinking water applications and approved by F&DA, these vessels have a high mechanical resistance and a working pressure of maximum 40 bar (notice that units work with a 5 bar pressure).

RICIRCULATION
In case of medium salinity water, extract recirculation (50% maximum) can be implemented manually allowing for an increase in the quantity of treated water produced.

DRINKING WATER STERILIZATION
The best solution for this service is, initially, a UV RAY DEBACTERIZATION PROCESS, chosen because it works by using electric current only (no chemical products). If an accumulation tank for the produced water is required then a solid chlorine slow discharge dispenser is available as an optional item.

DRINKING WATER TANK
The COMBI SHELTER has its own stainless steel drinking water accumulation tank.

MATERIALS
All the equipment is stainless steel except for vessels and sand filters which are made of fibreglass. All materials are corrosion resistant.

INSTRUMENTATION
We consider ease of use to be very important when designing systems – we intentionally use instruments that, in the event of accidents or breakages, can be easily found even in non industrial areas.

POWER GENERATOR
Generator with diesel motor.

ELECTRICAL CONTROL PANEL
Electromechanical automation of controls

CHEMICAL CLEANING
The chemical cleaning during brief non working periods (max 7 days) is automatic, while for long periods it is manual. One chemical wash per year is necessary.

PARE PARTS AND CONSUMABLES
According to specific requirements, the units have extra quantities of consumable products for periods of 1, 2 or 3 years.

RUN-TESTS
Granted that a COMBI SHELTER is available and not being used for emergency intervention, we can organize run tests for:
  • working capacity demonstration
  • training courses for local technical staff supported by audiovisual material and operating manuals in Italian and English (other languages optional).
