2 THE OPTIONS
2.1 Sandfilter
Fitted before the 20- and 5-micron filters, it allows a prime filtration, reducing consumption of the filter
cartridges. The sand filter is particularly interesting when the watermaker is operating in dirty seawater (e.g. silt,
suspended sand). The sand filter is equipped with valve(s) for the backwash, rinsing and filtration operations.
With a self-priming pump, it allows correct feeding of the sand filter and the unit, and if needed a possible
installation above the waterline.
A check valve needs to be installed at the sea water inlet hull fitting so the feeding circuit always stays
filled with water. This part is NOT supplied with the system, nor with the sand filter option.
There are 3 sand filter options available for the
- D250
- D450
- D450 with automatic sandfilter backwash*
* This option replaces the manual multi-position valve of the sandfilter by a motorized one. This allows the valve to
be piloted by the logic controller and perform the backwash cycle (filtration, backwash, rinsing and back to
filtration) fully automated after a single command or even programmed as part of the production cycle.
2.2 Post treatment neutralite filter
The neutralite filter consists of a reaction chamber that's designed to hold the "Neutralite" which is a "fossil
coral-like algae debris" based substrate that releases calcium and magnesium.
It allows to re-mineralize the produced water in order to elevate the PH and to add hardness. This results in a
more balanced water for consumption.
2.3 Post treatment chlorine dosing
A dosing pump with its solution container and check valve. This system allows to dose an additive (chlorine)
to prevent bacterial growth in the produced water reservoir.
2.4 Stainless steel strainer and an open-impeller feeding pump
This option is recommended for intensive operation of the R/O unit in more hazardous conditions. It consists
of a 3-way valve, the coarse sea strainer and the LP pump.
2.5 Stainless steel strainer and an self-priming feeding
pump
A self-priming pump ensures correct feeding of the unit,
allowing an installation above the waterline.
2.6 Remote control panel
The remote-control-touch-screen-module option allows to
command all basic functions and even full control of the
machine from a more convenient location.
