Description

DESCRIPTION

Protective and recovery system for saltwater lagoons

Technical sector

In the conservation of water and the environment of saltwater lagoons. Especially from the Mar Menor.

Background of the invention

Due to the heat and also to climate change, the lagoons and lagoons, generally due to their shallow depth and lack of water supply and clogging, are highly affected by solar radiation, causing their heating, evaporation and even their disappearance. It is said that in the Mar Menor the water is not renewed even once a year. As a consequence, its pollution and salinity increase, and the fauna and flora deteriorate or become extinct. Simultaneously producing the invasion, among others, of unicellular microorganisms that greatly harm the marine ecosystem. The water must be maintained with its typical salinity, which is slightly higher than that of the Mediterranean. Since this is the only one that feeds it.

They are also affected by waste from urbanizations, aquifers and chemical products from adjoining agro-industries, a group of industries that is responsible for producing, transforming and marketing the different agricultural products, livestock, fishing, biological natural resources, etc. with a large amount of nitrates, about 1575 tons a year in the case of the Mar Menor, nitrites, phosphates and pesticides. Pollution is also increased by the brine from some sewage treatment plants and by the contaminated aquifers that discharge into the lagoon, some due to leaks, and others when for some reason their level exceeds that of the lagoon. As a consequence, clogging, eutrophication, green soup and anoxia occur in the summers. All this is avoided or reduced by increasing the transfer of water from the Mediterranean, taking advantage of the fact that it is next to the coast and that it is the only water supplier to the Mar Menor with cleaner water and that it is also salt water. With fresh water it is practically impossible in that area, and it would also not protect the ecosystem.

However, as is the case with all the boulevards and rivers of the Levant, the polluted water must be discharged into the Mediterranean Sea, instead of the Mar Menor.

Through channels or ducts preferably made of plastic sheets or plasticized fabric, which are very cheap and allow very large dimensions. But reinforced concrete and other materials can also be used. In this way, agricultural waste would not accumulate, nor would the current problems with heavy rains or DANAS occur. Of course, simultaneously trying to carry out a treatment similar to that carried out with the other discharges along the coast.

THAT IS TO SAY THAT WHAT YOU NEED TO DO IS TO PREVENT THE MAR MENOR FROM BEING THE RECEIVER OF THE RAMBLAS, RUNOFFS AND DANAS OR BIG RAINS.

The confrontations that cause and delay their treatment and recovery and, as a consequence, the deterioration of the Mar Menor would be avoided.

This system does not demonize anyone, it benefits all groups and solves the problems of the Mar Menor.

For it:

a) Channels or ducts are used, either peripheral along the shore of the lagoon, or crossing it to the main sea, through which the water is sent (it can be sent filtered) in a simple and economical way with ducts made of plastic sheets or fabrics laminated. Although reinforced concrete ducts or channels can be used. b) With this system, daily waste from the ravines and aquifers and from the large avenues of rainwater are avoided, since they provide an excessive amount of fresh water and drag nutrients, pollutants or pesticides.

c) In addition, the mortality of fauna during hot weather is avoided, due to the anoxia that occurs due to contaminated water, eutrophication and heat.

d) The discharge water is taken from a high point shortly before it is drained into the lagoon. Larger solids are filtered out of these waters. e) Treatment plants can be applied, consisting of enclosures formed between a portion of the coast and a fabric filter barrier, where the waters to be filtered are sent. These enclosures can serve as storage.

f) Additionally, contaminated discharges into the lagoon must be reduced at the source. g) Water is extracted from the most superficial aquifers and, equally filtered, is sent through conduits or similar channels to the Mediterranean Sea. These do not need to be pumped, they can be discharged by gravity.

h) Simultaneously it is necessary to renew the water that is contaminated and with harmful species. The bottom that is filled must also be dredged, as occurs with swamps. But this must be done slowly and without repercussions in the water of the Mar Menor.

-IN THE MAR MENOR, SEVERAL ECOSYSTEMS HAVE EXISTED ACCORDING TO TIME AND THEY HAVE BEEN DESTROYED. CURRENTLY THERE IS NO SPECIES OF VALUE AND THOSE THAT ARE ARE MIXED. THEREFORE, THE MOST IMPORTANT PROBLEMS SHOULD BE SOLVED AND LATER, PART OF THE DESTROYED ECOSYSTEMS SHOULD BE RESTORED WITH NEW FAUNA AND FLORA.

Explanation of the invention

This system complements and increases the protection and recovery previously applied to the lagoon with water renewal systems.

The water is extracted from the aquifers, which is generally a small quantity, using pipes and motorized pumps that send the water to storage enclosures built between a dam and the shore of the lagoon. Aquifer pumps are activated when the level of the aquifer rises and a float or gauge closes an electrical switch. The ducts carry filters. The storage enclosures are covered with a biodegradable or non-polluting protective floating layer, which keeps it superficially isolated, based on some polymer, oil or water mixed with a product. preservative when it comes to solid waste of higher density than this. From the enclosures, the water and waste are sent to treatment plants.

Alternatively, this water, like that of the boulevards, can be sent to the Mediterranean Sea. Producing the extraction at a point somewhat higher than the level of the lagoon, the water can be sent by gravity.

The ducts can run along the bottom weighted or floating on the surface of the lagoon, conveniently marked.

Renewable energies are used to control and actuate the pumps.

The protective recovery system for the saltwater lagoons comprises an installation with which the water from the ravines and aquifers is sent directly to the greater sea, characterized in that it comprises:

a) A land channel around the perimeter of the lagoons that transport water from the ravines, aquifers or DANAS to the greater sea.

b) A channel that occurs between the shore of the Mar Menor and a breakwater that runs parallel to it.

c) Conduits made of plastic sheets or plasticized fabric that transport water from the boulevards, aquifers or DANAS to the greater sea.

d) Some channels open at the top, made up of plastic sheets, fabrics or plasticized tarpaulins, which carry inflatable ducts or cylinders on their lateral edges.

e) The inflatable cylinder ducts use independent sections to allow the passage of ships.

f) Some small dams that regulate the supply of water interspersed in each of the boulevards, especially when heavy rains occur.

g) At the entrances of the channels, in addition to the filters, nets are applied that prevent the passage of fauna, flora, objects and garbage between the two seas.

h) Some enclosures formed at the exits of the boulevards between the shore of the lagoon and a dam.

i) Some enclosures formed at the exits of the boulevards between the shore of the lagoon and a band of fabric or canvas, which carries a ballast on its lower edge and some floats on the upper one.

j) A power supply installation with renewable energies.

k) A microprocessor with the signals of: day of the year, time, sea and air temperature, humidity, whether sunny or cloudy, wind intensity, wind direction, water temperatures, water pollution (including the degree of oxygenation ) Y of the control panel, processes them and sends them through a transmitter, receiving them in receivers in the areas of the electric motors, solenoid valves, plates or gates, pumps or motor pumps that it activates, it also provides visual and audible warnings of operation.

l) A control panel is used to actuate or control the system.

m) Communication can also be done by mobile phone and y program.

n) Optionally, purifiers can be applied consisting of enclosures formed between a portion of the coast and a canvas or fabric filter barrier where water is sent from the lagoon, filtered out towards the lagoon through the fabric filter barrier. The deposited sludge is extracted from the enclosures for treatment. These enclosures can be used for interim storage.

The water in the boulevards is regulated by dams and is concentrated with dikes or canals, sending it to the main sea or stored between the shore of the lagoon and a dike, or (in a variable way) between it and a strip of canvas or cloth. , connecting these to each other and unloading through ducts to the greater sea or to some sewage treatment plants. Adding a channel that runs along the shore and is part of the Mar Menor. Most of the runoff water is usually concentrated in the Albujón boulevard (it is practically an artificial river with a flow of 1,000 liters per second) and a little in the Miranda boulevard, for which reason using storage enclosures only at the exit of these boulevards could be enough. The water is sent by gravity or by pumps powered preferably with renewable energy.

The current polluted discharges that go to the lagoon must be reduced or eliminated.

Especially for the DANAS, it is advisable to use larger channels made of plastic sheet or plasticized fabric with a semicircular or V-shaped section, open at the top. They carry rigid or inflatable ribs. Which can be extended and retracted since most of the time they are not necessary. They are weighted, for example, with cables that provide additional weight.

It shows a conduit (8) with an angular or semicircular section, made of plastic sheet or plasticized fabric and its edges limited by inflatable air conduits (9), which act as floats and shape the channel. That sends the water from a little before the mouth that is higher and through a filter (23d), discharging by gravity into the Mediterranean Sea. You can have an arch, semi-circular, or V-shaped frame or ribs to keep the shape. You can also use inflatable ribs or legs to give it shape. In the central or lower area it carries the ballast (9w).

It shows a conduit (8) with an angular or semicircular section, made of plastic sheet or plasticized fabric and its edges limited by inflatable air conduits (9), which act as floats and shape the channel. It carries some sections (8a) with inflatable ducts on their edges (9a) also ballasted (8w), which, when deflated, allow the passage of ships. That sends the water from a little before the mouth that is higher and through a filter discharging by gravity into the Mediterranean Sea. You can have an arch, semi-circular, or V-shaped frame or ribs to keep the shape. You can also use inflatable legs to give it shape. In the central or lower area it carries the ballast (9w).

Figure 9 shows an aquifer (41f) from where the water is extracted through the filter (23), and the conduit (21f) by means of the motor pump (22f) being stored in the storage tank (40f) from where it is sent to the treatment plant (24). If solid waste is obtained, it will be done using a conveyor belt or vehicles.

Figure 10 shows an aquifer (41 f) from which the water is extracted through the filter (23), through the conduit (21f) by means of the motorized pump (22f) and through the Mar Menor (1) towards the Mar Mayor. The motor pump is activated when the level of the aquifer rises and a float or gauge (43) closes an electrical switch with the conductor (44). In this case, you can even use a tank or reservoir because the amount of water is usually not very important.

Figure 11 shows an aquifer (41f) from which the water is extracted through the filter (23), through the conduit (21f) by means of the motor pump (22f) and stored in the storage area (40) limited by the dam ( 42) that makes it independent from the water of the lagoon (20), from where it would be sent to a treatment plant. The motor pump is activated when the level of the aquifer rises and a float or gauge (43) activates it electrically by means of a switch and the conductor (44). The storage enclosure can have a protective floating layer (45), biodegradable or non-polluting, which keeps it superficially isolated, based on some polymer, oil or even water mixed with a preservative product can be enough when it comes to solid waste from higher density than this.
