外来海洋生物の侵入の主な経路の1つはバラスト水です。船舶のバラストタンクや貨物倉には、バラスト水として淡水や海水が貯留されています。
船が貨物を運んでいないとき、十分な貨物を運んでいないとき、または海が荒れているために安定性を高める必要があるときに、航海中の安定性と操縦性を高めるために利用されます。
船が橋やその他の構造物の下を通過できるように水中で十分に低く浮くために、バラスト水を利用して重量を増やすこともできます。
通常、船が貨物を港に引き渡し、貨物がほとんどまたはまったくなし状態で出港するとき、バラスト水がバラストタンクに注入されます。次の寄港地では、船が新しし\貨物を積み込むときに、バラスト水が移送され、排出されます。
船舶は、多数の港に荷物を引き渡したり、受け取ったりする際に、各港で少量のバラスト水を排出したり、取り入れたりすることがあります。このような状況では、いくつかの港からのさまざまな水が船のバラスト水に存在します。
バラスト水の排出は、外来生物を排出口に持ち込む可能性があります。外来種、外来種、および非固有種は、バイオインベ一ダ一としても知られるこれらの導入種の別名です。
前述のように、バラスト水の排出は本来の海水環境にとって危険であり、水生生物に害を及ぼします。近年、環境や水生生物の保護を重視する人が増えています。バラスト水の有害性を認識した後、ろ過が義務付けられています。
2004年に、国際海事機関(IMO)は、船舶のバラスト水および堆積物の制御および管理に関する国際条約を策定しました。
ここまでで、バラスト水の排出にようやく基準ができました。これはまた、規制を達成するために水を浄化するために、貨物船にろ過システムが必要であることを意味します。
バラストタンクは水族館にたとえることができ、独自の生態系を持っています。しかし、それが海中の別の場所に放出されると、その地域の水生生物にとって非常に有害で危険です。
ろ過の目的は、これらの生物やその他の汚染物質の放出を防ぐことです。バラスト水には、クラゲ、カ二、バクテリ ア、プランクトン、ウイルスなどの生物が大量に存在し、 下流のパイプやその他の機器を簡単に詰まらせる可能性があります。
バラスト水用に最も一般的に使用されるフィルタ一は、フィル夕ー定格50 umの自動逆洗フィルタ一です。フィル夕一は、バラスト水が通過するときに、50 umを超える海洋生物を自動的に除去し、近<の海に戻します。また、パイプを詰まらせ、さらに先の機器に害を及ぼす可能性のある粒子状汚染物質を除去します。
ろ過は、パイプや機器の保護のためだけでなく、水生環境のためのものでもあります。時には、利益だけを気にすることはできません。長期的なビジョンについて考える必要があります。バラスト水のろ過は良し\例で、機器や地域の生態系の汚染物質をろ過する必要があります。

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…
The science and practice of extracting metals or metal compounds from minerals and transforming them into metallic materials with specific qualities using a variety of processing techniques is known as metallurgy. With the development of technology and the metallurgy industry, the filtration market in this area grows quickly annually. The need for filtration is increasing and the filter equipment is also developing. In the metallurgy industry, the rolling mill coolant and lubricate system need a filtration system. Equipment coolant and lubricating oil need to be filtered to remove contaminants and accomplish recycling in the metallurgical process in order to save input costs. Filtration can help to extend equipment service life and help equipment stay at optimum level. Based on their different filtration needs and characteristic, they have respective suitable filtration elements. For the rolling mill coolant system, continuous filtration is crucial, so the automative self-cleaning filter is a great choice for this system. When it comes to the hydraulic and lubricating system, the most important point is to remove the tiny metal debris and other impurities generated due to thermalization. Depth filter cartridge can be the best choice for this operation, which can effectively eliminate the undesired micro impurities. Brother Filtration,…
The Paper industry has a centuries-old history, our ancients used the traditional way to produce paper, and now we use advanced technology to produce more delicate and high-quality paper for all kinds of uses. The tissue, the printing, publication, and the packaging, all need paper. Behind the pliable and smooth surface of a piece of paper, there are many procedures that need filtration. The starch slurry, which is the primeval form of the paper requiring filtration to improve the quality and eliminate the undissolved starch particles. The exquisite coated paper, you often find in magazines or the first few pages of a book, is processed by the coating technology. The coating paints also need to be filtered. According to the viscosity level, there are different types of filters suitable for low-viscosity and high-viscosity liquids. Water is the basic and key resource for many industries, pulp & paper is no exception. Using a filtration system to filter lakes or rivers’ water is a cost-effective way to do water resources management. Additionally, wastewater can be reused and lawful discharged after filtration. Filtration plays an important role in the pulp & paper industry, infiltration for this field, automative self-cleaning filter is the most…
