WATERMARKERS

Our systems are built for long term operation with minimum problem at sea water circumstances.
Our water makers are the most convenient systems for yachts, ships and hotels according to energy usage, potable water capacity and life time. The equipments used at our systems are resistent to high corrosion like sea water. The high pressure pump head is titanium or bronze, membrane vessels are fiberglas and the instruments, fittings are all high quality stainless steel.
The main control panel monitors every step and situation of the system like the quality of the permeate, working pressure, water temperature. The flush of the membranes are made automatically after determined period. The diverter valve protects permeate to go to storage tank if the quality is not good.
From the display panel, the situation of the system, faulth messages and any maintenance requirement message are displayed.
There is not limit for the capacity of the systems from minimum 200 GPD.

Desalination by Solar Energy and Waste Heat :

The principle of this distillation process is based on evaporation of water and condensation of vapour to and from humid air. The humid air flows in a circuit driven by natural convection between condenser and evaporator.

In the evaporator the hot sea water, being hetaed e.g. in a solar collector, is distributed onto vertically hanging sheets and is slowly trickling downwards. The air moves in counter current flow to the brine through the evaporator and gets saturated with humidity. Partial evaporation cools the brine which leaves the evaporation unit concentrated with higher salt content and a reduced temperature.
In the condenser unit the saturated air precipitates on a flat plate heat excahnger. From here the produced very clean water is trickling into a collecting basin. The heat of condensation is mainly transferred to the cold sea water thus the temperature of the raw water in the condenser rises significantly, evaporation heat is regained partly.

In the next step the brine is heated up to the evaporator inlet temperature, which is between 80-85 °C. This heat can be performed e.g. by highly efficient solar collectors, from a thermal storage tank, by waste heat or wind energy.
