Ballast Water - Science topic

I want to use a chemical material for ballast water treatment. I want it to be anti algae, microbicide, cost effective and biodegradable that be environmental friendly. I want to use it in dosing system and to invest my company energy on it. I read many papers about Seakleen and Peraclean. If you have any offer further than these two please let me know.

For the purpose of bulk vessel stability,

An empty vessel is filled with ballast water, but on a full cargo load, ballast water is emptied. during the vessel system operation, I want to simulate the ballast water flow rate and pressure rate in the pipe for the purpose of bulk vessel stability.

So, what kind of simulation software should I use? please, suggestions and guides will be greatly appreciated.

Could you advise on a less costly and efficient method to remove chlorides from wastewater stream (oily water, oily surface water, ballast water)? After combining all the three streams, the chlorides content is 1500 ppm. I need to reduce it in order to avoid fouling and corrosion on the next equipment. The discharge limit according to the standard for free chlorine is 2 mg/L.

Next to marine pollution, bioinvasion is a biological pollution which is mostly due to ballast water discharges from ships. Biological invasions are creating increasing interest both among Scientists and environmental managers. Globalization of international trade has promoted numerous biological invasions, mnay of which are both ecologically and economically costly (Levine and D' Autonio, 2003; Perrings et al., 2005). A very large number of marine species are moving across the world's oceans at an increasing rate. The ecological and economic consequences of this re-distribution of important species are no less worrying is the case for terrestrial and fresh water systems (Marine Pollution bulletin editorial 2007)

Sincerely, all researchers and friends active in the field of ballast water management, please complete my research questionnaire on the subject of "Review the implementation of the Ballast Water Management Convention in Iran" and send it to me.

I attach the file and link for online quary

Thanks a lot

Connected technologies Ballast Water Treatment.

There is evidence of Corbicula (in this case fluminea, an invasive species i.a. in Europe and North America) that the species is "moving" upstream in small rivers and streams where the usual suspects shipping (i.e. ballast water) and transport of dredged materials (gravel extracted from the river bottom or from already "infested" gravel pits) are not acting. What other "agents" might be responsible for the upstream migration of the Asiatic clam? Any ideas or proofs of alternative ways for spreading of Corbicula (as larvae or adults)?

how can I determine shear stiffness and shear damping between adjacent ballast

masses in the ballast model? I can not find any paper on this issue.

We are working on Ballast Water Management System (BWMS) which involves a filtration unit and an UV reactor in it. To understand more about UV system and for the type approval under USCG,  we need to know about the UV transmittance of sea water in US coasts. 

Currently I'm looking for a data for treated wastewater in Singapore. This is because i want to make comparison for the treated ballast water and treated municipal wastewater in terms of quality standard and quantity. For the quantity, i need to now how many municipal wastewater is treated in Singapore. I hope I can find the latest data for the quantity of treated municipal wastewater in Singapore.

Hereby, I'd like to invite you to participate in giving the perspectives, if you are interested in this topic. By giving a response to the questionnaire (the full detailed questions are in the project update page). 

I apologise if this format is not suitable for Q&A section. that's why I put the detail in the My Project Update page. 

Cheers, 

Am working on the Ballast Water Treatment System using UV-C Radiations with Medium Pressure Mercury Lamp. 

Am researching on Ballast Water Treatment System using UV radiations. So its important to know the UV Transmittance of sea water in different ports of the world for modeling of the system.

Please find the attachment(excel sheet) in which I have collected some information, but it is not sufficient. Help me with some more data of this kind.

Am working on the Ballast Water Management System, where we use a UV sterilization unit.

According to some previous studies a minimum sterilization dose of 16,000 micro Watt seconds per cm² is required and most of the UV sterilization manufacturers uses a range between 30,000 to 50,000 micro Watt seconds per cm².   Is this the right assumption?

What is the right UV sterilization dose that can be used for treating the Ballast Water (sea water)?

Does anyone known if there is a recommendation for bacterial regrowth in ballast water treatment? For instance if you need to regrow the bacteria for 2 or 7 or 20 days?

I did not found any reference and i'm wondering if there are any or if there is an amount of bacteria that is accepted after the treatment in ballast water.

Thanks

According to the definition of marine-vectors.eu, "outbreak forming species (OFS) are indigenous species or invasive alien species (IAS) undergoing pulse-like, short-term (days to few months) exponential population growth during which they have an adverse effect on one or more of the following: biological diversity, ecosystem functioning, socio-economic values and human health."

With the purpose of defining an early warning system for ballast waters management, we are trying to build a list of OFS, particularly concerning IAS as well as native harmful species. Can anyone help us in finding such information? Are there general criteria (biological features, ecological features, etc.) to identify OFS within a taxonomic group?
