ON-SHORE BALLAST WATER TREATMENT FACILITY
1.Alternative Methods for Managing Ballast Water
Harm to the ecosystem by using alternative methods of ballast water treatment prevented or can be reduce. It may seem as the only way to reduce the risk of ballast water treatment, although in theory, the development of ballast water exchange standard ballast water treatment methods, intake port to the facility including the removal of the criteria can be evaluated with the method.
A few strategies have been developed, often including one or many of the following complementary methods. First of all, the entry into the ballast tank to ballast water minimize retrieving of organisms. For example ballast water must be avoided when exist the turbulance in

Process of disposal of harmful marine organisms and pathogens in ballast water from a reception facility must be environmentally and unhealty for people and marine lives. Ballast water will be discharged to the aquatic environment should be provided in ballast water performance standard specified in Regulation D-2 of the Convention. (Guidelines for ballast water reception facilities. (2012)).
1.1.2. Capabilities of On-Shore Ballast Water Treatment Facility
A treatment facility has details of capabilities and capacity limitations; intend to use this plant should be made available to the marine vessels.
The treatment plants that can be used to ship’s capacity limits and capabilities are highlighted in the International Maritime Organization (IMO) guideline. The details made available to ship’s capabilities and capacity limitations is:
• Maximum volumetric capacity of ballast water;
• Handled the maximum volume of ballast water in any time;
• Maximum transfer rates of ballast water (cubik meters per hour)
• Operation in an hour;
• Access to the facility is available such as ports, berths and areas;
• Pipeline connection details of ship to shore (pipeline size and reducers
Nitrogen and nitrates relate to Hypoxia via the process of eutrophication. Since Nitrogen is a limiting nutrient in most waters, the added input of nitrate causes massive growth in algae. The algae rapidly consume all available N, and once the nutrient is limited again, the alga dies en masse. As the alga decomposes, oxygen is depleted in the water. This lowers dangerously lowers the level of dissolved oxygen in the water, which harms living organisms in the area. Small organisms and organisms that are immobile or unable to escape low-oxygen areas are particularly vulnerable. Hypoxia and resulting “dead zones” are harmful to local fishing and shrimping industries and algal blooms hurt the tourism industry. Hypoxia has lead to a decrease of about 25% in the brown shrimp habitat, forcing shrimping operations further offshore. As the hypoxia issue continues to grow, negative human effects will only increase. Since nitrate runoff from ag. has been proven to be the dominant source of hypoxia, policies could be enacted to effectively deal with “point-source” pollution. This makes enacting environmental policy more easily adapted, possibly included in past policy such as the Clean Water Act.

Although a freshwater tank can be full or color, it does not come close to the fiery colors that are present in a marine aquarium. Unfortunately, all the color and life that a marine aquarium holds is much more fragile and not as easy to keep as a freshwater tank. Therefore, the marine aquarium requires a plethora of devices working together and at optimum levels to maintain a successful tank. Items like protein skimmers, ultraviolet filters, sump filters, reverse osmosis units, and even wave-makers are just a few of the devices that are required to properly maintain a marine aquarium. With the exception to a properly constructed tank, nothing is as important to the marine aquarium as the water within the tank and the lighting given its inhabitants.
Warmer water temperature discharged by waste industrial heat into water can affect many aquatic species that cannot tolerate the warmth. A higher level of temperature can result in low oxygen concentrations by speeding up the rate of decomposition of organic matter. "The discharges are often associated with coal-or nuclear-fuelled power plants, and sometimes with large factories." (H.J. Dorcey). The increase of heat materials dumped into water can increase the temperature level in the water bodies and can affect all living organisms within that body. There are many disadvantaging technology which has been affecting water and raising the water temperature from normal. For example, electric power plants might withdraw water from nearby water bodies for the purpose of cooling in the plant and then return the heated water back to the same water body. This is insanely affecting the regular temperature. If the water is not the same, it can lead to many damages within the water body. For example, fishes will dies exhausted from the warmth and it will also affect other aquatic organisms causing them to boil in the water caused by others, sacrificing these creatures. Water from excessively heating up can be best prevented by using special cooling towers and ponds that disperse the energy into the

Desalination plants overall could be a huge benefit to society for its high quality of water and intuitive water treatment techniques, however the big environmental impacts and high costs to produce water at a desalination plant makes it unfavorable to most communities especially the poorer communities. Although costs for the production and upkeep for a desalination plant has been going down while the technology of it rises, the only true benefit for having a desalination plant would only come into affect when it is near a body of ocean, such as Tampa Bay Water. All in all desalination plants could soon be the face of future water treatment plants and water sources, but for the present time it is still only a niche water source.
Container shipping industry is kind of international trade and destined restricted by los of regulation, such as ocean environment law, nation’s imports & exports law.
Fairly inexpensive compared to other techniques, the financial savings of bioremediation is an attractive alternative when used properly. A study conducted by Alper “states that bioremediation is six times lower in cost than incineration and three times cheaper than entombment.” . After the Exxon Valdez spill, the cost to clean the shoreline was less than cost to provide physical washing of the shore for one day. This saves a great deal of money which would be spent on labor hours, and it also allows for time t...

The bacteria and wastewater is mixed in an aeration tank and therefore the contaminants are removed by action of sorption and series of breakdown by the bacteria.
Waste water treatment plants are essential to communities of all sizes and must work efficiently. Waste water treatment plant primary priority and responsibility is the treatment of incoming sewage water by the removal of biological and chemical wastes so it can be treated and recycled for future use. There are many government agencies and standards set forth to govern and observe the successful treatment of sewage such as: the Department of Environmental Quality, the National Pollutant Discharge Elimination System and the Clean Water Act of 1972. Compliance and constant monitoring of the treatment plant’s operations are important; as they protect the surrounding community. A spill or backflow of sewage due to a complete system malfunction could potentially be detrimental to the environment and local community. A precise system, of which must be compliant according to government standards, is critical to maintain low levels of wastes that are returned to neighboring water systems after treatment.
Before delving in to what is actually wrong with seawater desalination plants, it is important to establish that there are plenty of alternatives available. One of the best alternatives is to adopt more efficient practices, such as conservation of water, and recycling storm water and grey water (from washing machines and bathrooms...
Improvement and upgrading of wastewater treatment processes and also the need to reduce the environmental factors make the use of tertiary wastewater treatment important.
Water Pollution is a current issue that has serious consequences; it progresses everyday in our lakes, oceans, rivers and other bodies of water.
Water transport is not flexible because it is restrained within water bodies. The use of containers has becomes the best inter-modal option for water transport whereby goods are placed in containers and transported through truck or rail to the port where it is loaded in to a container ship. Upon arrival to the destination port it is offloaded and transported again by track or rail to the consumer of customes.This helps reduce staffing needs, transit time and damages (Haulk, 1998).
