Uma das principais vias de introdução de organismos marinhos exóticos é a água de lastro. A água doce ou salgada é mantida nos tanques de lastro dos navios e nos porões de carga como água de lastro.
Quando os navios não transportam carga, não carregam carga suficiente ou quando é necessária maior estabilidade devido a condições de mar agitado, ela é utilizada para melhorar a estabilidade e a manobrabilidade durante a viagem.
Para que um navio flutue suficientemente baixo na água para passar sob pontes e outras estruturas, a água de lastro também pode ser usada para aumentar o peso.
Normalmente, quando um navio entregou carga em um porto e parte com pouca ou nenhuma carga, a água de lastro é injetada nos tanques de lastro. No próximo porto de escala, quando o navio recebe nova carga, a água de lastro é transferida e descarregada.
Um navio pode descarregar ou receber uma pequena quantidade de água de lastro em cada porto ao entregar ou receber carga em vários portos. Nessas circunstâncias, a água de lastro do navio contém uma mistura de águas provenientes de diferentes portos.
A descarga de água de lastro pode introduzir espécies não nativas no porto de destino. Espécies exóticas, espécies introduzidas e espécies não autóctones são outros nomes para essas espécies, também conhecidas como bioinvasoras.
Como mencionamos anteriormente, a descarga de água de lastro é prejudicial ao ambiente marinho original, causando danos aos organismos aquáticos.
Recentemente, cada vez mais pessoas têm dado importância à proteção do meio ambiente e dos organismos aquáticos. Após perceber a nocividade da água de lastro, a filtração tornou-se obrigatória.
Em 2004, a Organização Marítima Internacional (OMI) estabeleceu a Convenção Internacional para o Controle e Gerenciamento da Água de Lastro e Sedimentos dos Navios.
Até agora, a descarga de água de lastro possui uma norma definida. Isso também significa que é necessário um sistema de filtração nos navios de carga para purificar a água e cumprir as regulamentações.
Os tanques de lastro podem ser comparados a um aquário, pois possuem seu próprio ecossistema. No entanto, quando descarregados em outra parte do mar, são extremamente prejudiciais e perigosos para os organismos aquáticos locais.
O objetivo da filtração é evitar a emissão desses organismos ou outros contaminantes. Há grandes quantidades de organismos na água de lastro, como águas-vivas, caranguejos, bactérias, plâncton e vírus, que podem facilmente obstruir tubulações e outros equipamentos a jusante.
O filtro mais utilizado para água de lastro é um filtro automático de retrolavagem com capacidade de filtração de 50 µm. O filtro remove automaticamente espécies marinhas maiores que 50 µm e as devolve aos mares próximos quando a água de lastro passa por ele.
Também filtra partículas contaminantes que poderiam obstruir tubulações e danificar equipamentos subsequentes. Para atender a essa necessidade, a Brother Filtration também fornece filtro horizontal.
A filtração não serve apenas para proteger tubulações e equipamentos, mas também o meio ambiente aquático.
Às vezes, os benefícios não podem ser a única preocupação; devemos pensar em uma visão de longo prazo. A filtração da água de lastro é um bom exemplo, pois precisamos filtrar os contaminantes tanto para o equipamento quanto para o ecossistema local.
A Brother Filtration está profundamente envolvida no campo da filtração. Fazemos tudo relacionado à filtração e resolvemos todos os problemas de filtração.
Mais do que fabricar produtos de filtração, também fornecemos soluções de filtração para nossos clientes. Nosso filtro automático de retrolavagem e filtro horizontal pode ser a escolha perfeita para a filtração de água de lastro.
The ocean occupies most of our planet, and desalination has been used more and more widely over the past 20 years. By using reverse osmosis systems, we help desalination plants to do their job and further help more plants to solve the problem of water shortage.
Every chemical plant is inseparable from industrial water filtration systems. Whether it is the purification and filtration of raw materials and final products or the treatment of industrial wastewater and unwanted chemicals generated during the production process, industrial filtration is a top priority.
Most petrochemical industry products are stored in large containers, such as diesel, gasoline, and fuel oil. This type of storage is highly likely to lead to impurities in the products and affect the product quality. Our mission is to offer efficient and reliable filtration systems for the petrochemical industry so that purification is not a big challenge.
The extremely rapid growth of the pharmaceutical industry has created a greater demand for industrial filtration. Whether it’s upstream cell fermentation, purification, or filtration, we can provide the solution. In addition, We are committed to filtration and separation, protecting the reliability and safety of production equipment.
The food and beverage industry is closely related to the daily life and health of each of us. Therefore, we must meet higher standards to filter these products. As your experts, we help you improve product quality, reduce production costs, and safeguard everyone’s health.
Nature itself has the ability to treat wastewater. But with the huge increase in human production and living activities, it can no longer handle such large amounts of wastewater. We, as industrial treatment producers, help nature to share the burden of wastewater treatment.
Industrial wastewater from mining activities contains high volumes of heavy metals, particulates, and residual chemicals. Wastewater must be purified and filtered in order not to pollute our water resources. We help your plant meet wastewater discharge standards.
In order to extract oil more efficiently and conveniently, large amounts of water must be injected underground to ensure water pressure. And since precious water resources are limited, our technology allows wastewater to be purified so that it can be reused.
When it comes to marine filtration, the first scene that appears in people’s is usually the sea or seawater. But marine filtration is more than seawater. A crucial resource on this planet is seawater. Large amounts of seawater are needed to generate fresh water for drinking and irrigation in locations with a lack of fresh water, just as ships sailing on the ocean need a lot of it for ballast water to keep the ship balanced. Marine filtration is not only about the seawater, but also the transported seawater. The ballast water is a kind of transportation of water. The cargo ships load the seawater from one place and discharge it at another port. The seawater traveled with the cargo ship in ballast tanks. This is the point many people will be indifferent about, the filtration before the discharge of the ballast water. People are familiar that we can not drink seawater directly, because it contains large quantities of salt and contaminants. But why do we need filtration for ballast water? it is just the seawater discharge into seawater. With the development of the environmental protection concept and the perfection of the law, we are constrained to filter the ballast…
