in july 2010 some satellite images revealed to colossal algal bloom covering approximately a surface area of 377.000 square kilometres ( 146.00sq mi) in the baltic sea The algal bloom spreaded out from Germany and Poland to Finland.


Making the Seas Livable Again

Do you know how CO2 affects the seas? The CO2 coming out of your car mixes with the sky. The seas and oceans absorb 30% of this CO2. In this way, the pH of the water rises. So seawater becomes more acidic. The effect of this on living things with simple organisms is so great that it almost disappears .

So where do the algae that cover the sea surface come from? After fertilizing the agricultural lands to the full, it reaches the rivers and the seas through underground channels through rain. They reproduce incredibly in nutrient-rich seawater and close the sea surface. The sun can no longer go under the sea and it is no longer a place to live.

Here, with the Haurvatat project, we are trying to find solutions to these problems from there.

Researchers of this phenomenon have registered that algal blooms have occured every summer for decades the runoff of chemical fertilizers from surronding agricultural land. Approximately 100000 km2 of the baltic seafloor almost a quarter of its total areas is a variable dead zone. A depletion in oxygen is noticed on the bottom due to the fact that the more saline and denser water can be found at ist bottom. Research chalim that its mainly bacteria that grow in it’s digesting organic material and releasing hydrogen sulfide.The baltic seafloor has gone through a series of pollutions since the world war whereas a number of element were dumped and till date it still suffers from it , there the seafloor ecology drastically differs from that of neighbroring atlantic.

Nutrient enrichment increased primary production, decomposition & oxygen consumption.

Oxygen depletion Poor water quality Survival competition Increased decomposition.

Fewer consumers water polution concentration of nitrogen & phosphore uninhabitable zone .

Origin of Eutrophication

The colder the ocean, the more CO2 it absorbs from the atmosphere and takes up 30 percent of global fossil fuel emissions.

Plastic is found in the ocean to a depth of 11 km, meaning synthetic fibers have polluted even the most remote parts of the world.

Many marine organisms cannot distinguish ordinary plastic materials from food. Plastic-eating animals often starve to death because they cannot digest plastic and fill their stomachs, preventing them from eating real food.

How Contaminated Sea Water Is Taken In

Assists in reducing & countering the strenghts of waves, currents &  other natural disasters that  can occure at any time before redirecting it to the  filters . 

How water enters the station & moves towards the allocated filters for recycling and more…

Communal space, a simulation of a park whereas humans and animals get to be in interraction with each others for mental health purposes.

Waste Particle Selection

Particle selections from big to small going through various sized filters conecutively.

This is the Last filter, also the smallest it collects the algae & redirects them to a tank for redistribution after several treatmentrs.

Manufactoring  laboratory for algae & watse recycling before redirecting them seperately for allocated purpose .

Algaculture System

Bioenergy dominated environment with algaculture &storage system .

The use of bio luminescence concept which absorbs co2 & diffuse O2 into the internal atmosphere .

Hilal returning  every unprocessed  elements collected  into the station .

Sub-Ship Hilal's Features

Hilal detects potential blooms and waste through sensors then navigate towards the location for collection.

Hilal collects the algae and processed whilst injecting slaked lime into the water.

Hilal produces  enough biofuel for its own energy  uses & return any  unprocessed elements  back to the station.


Heat Conservation and Redistribution

In order for proper heat conservation we put inplace  insulated floors ceilings and walls .

Heats from machinery is stored and reinserted within the station in order to regulate the internal temperature.

Stored heat  redistribution within the station.

Wind Turbine and Water Movement

Waste Water Recycling System

Grey & black water filtering system The water comes from the activities that are  happening on and  inside of the station it goes through a series of processing before being reused .

A series of filters are set in place to process the water  & then redistribute it accordingly either to the above sea level farm and others…

Above the sea level we can see a shelter for domestic animals They are needed for farming , soil enrichment & food for human needs .


Ecosystem Reclamation Process

Healing process with nidal as the catalyst & life is slowly returning.

Over the Years

Baltic Sea2020 - 2120

Year: 2020

-Locating the major algal bloom zones in the baltic sea.

-Choosing a strategic location to build the main station.

-Initiating the first action plan that involves algae , other waste collections. 

-Introduction of mobiles sub-station or residencies that assist the main station by beign sent out.


-Continuous growth. 

-Supplying farmers with bio-fertilizer & good habits. 

-Baltic Sea slowly re-claiming back its environment and ecosystem.

Year : 2170

-Continuous growth.

 -Implementation in other zones around the world.
