Cleaner Production and Its Application in Marine Environment
Song Museok ;
Journal of the Korean Society for Marine Environment & Energy, volume 6, issue 3, 2003, Pages 3~15
The concept of 'Cleaner Production(CP)' and various activities aiming at promoting CP are investigated along with the applicabilities of CP to marine environment. Although the conventional approaches dealing with the marine pollutions can be absorbed in CP, the whole activities of Production and conservation in the ocean must be projected into a new Paradigm, 'Sustainable Development.' Renewable energy is the first key to a complete CP and the ocean can provide us with the clew. In order to introduce CP system more effectively to marine environment opinion collection, environment monitoring, problem identification, resolution proposition, state-of-the-art evaluation, policy development, communication, education and public information are to be Planned and followed up systematically KOSMEE is believed to be a good structure to stand at the center of the upcoming CP activities in the ocean.

In this paper, the reduction of green house effect gas CO₂ emission and NOx gas emission by using the RORO ship coastal transport of import-export container cargo was investigated. At first, the domestic CO₂ gas emission and the transportation of import-export container cargo were Investigated. Next, the characteristic of a RORO ship and CO₂ emission standard and NOx emission standard were investigated. And also, the reduction of CO₂ emission and NOx emission by the shift of coastal transport from land transport for the transportation of import-export container cargo between Kyongin area and Pusan Port were calculated. Finally, the change of CO2 and NOx gas emission due to the change of the share of coastal transportation and the load efficiency of RORO ship are investigated. The research results show that the shift of RORO ship coastal transport from land transport was very effective to reduce the CO₂ emission but it was no good to reduce the NOx emission.

Collected and analyzed the coastal processes at the estuary of Nak-Dong river and its near coastal area from the history of field measurements. Introduced a numerical model to predict three dimensional topographical change which are evaluated from the nearshore wave and the wave induced current fields for the objective area, and later it were related to the development of beach and shoals. With the comparison between measured and calculated, we found that the changes on the coastline and sand spit and bar development are induced not only by artificial forces due to the construction of river dike, but also by the strong impact of wave induced current. In future days, it is expected that coastline change and sand bar development at the lee side of Jinwoo-Deung and at the front of Dadae beach.

To know the penetration behavior of spilled oil into sandy beach sediment is very important, because the penetration depth of the stranded oil into the sediments is one of the most significant information to know effect of spilled oil on biological communities and to set up cleaning method. The purpose of this study is to clarify the effects of wave and/or tidal action on penetration of spilled oil into the sediments and to clarify main factor in oil penetration using sandy beach model. Specific conclusions derived from this study are as follows. Spilled fuel oil C penetrated into the sediments only by falling tidal fluctuation and not by wave action on sandy beach environment, and the first tide is most important for the penetration of stranded oil. Over 80% of bulk fraction in penetrated fuel oil C was concentrated to the top 2 cm sediment-layer. Moreover, the penetration of stranded oil into the sandy beach sediments was strongly correlated with the oil viscosity affected by temperature.

Discharging untreated bilge to the ocean is a cause of marine pollution. In general, bilge water contains free and/or emulsified forms of oil. Free form of oil can easily be separated by gravimetric flotation and/or proper filtration processes. However, those simple physicochemical processes could not separate emulsified oil without adding proper chemicals. Electrolytic flotation is one of promising technologies able to fulfill the effluent standard requirement, which is below 15 ppm of oil content. In this research, Electrochemical process consisting of electrochemical flotation basin was studied for the treatment of emulsified oil. In order to estimate, the effectiveness of oil separation equipment influent concentration of oil and HRT(Hydraulic retention time) were considered. Also, lab-scale electrochemical process was designed and operated in the condition of various HRT, current density, and electrode gap. Through the research, following results were obtained. From the experiment of bench scale electrochemical treatment process, it was demonstrated that the emulsified oil was treated effectively and the removal efficiency of emulsified oil from wastewater was increased with HRT and current density.
A Study on the Basic Design of a Remotely Operated Recovery System for Removing Toxic Liquid Contained in a Sunken Ship

Journal of the Korean Society for Marine Environment & Energy, volume 6, issue 3, 2003, Pages 54~62
This paper surveys a number of remotely operated recovery techniques and their recent applications in the removal of the toxic liquid from sunken ships, and suggests the appropriate recovery technique for our ocean environment, especially, in view of its cost and efficiency. Authors also give the technical requirements for the suggested remotely operated recovery system and the basic design result which is well-matched with such requirements.
Seasonal Variation Estimation of Inflow Pollutant Loads of Yeong-il Bay by using Tank Model
Lee In-Cheol ;
Journal of the Korean Society for Marine Environment & Energy, volume 6, issue 3, 2003, Pages 63~71
This study investigated about the seasonal variation of pollutant loads flowing into the Yeong-il bay from constructing Tank model which is the simulation model to evaluate the daily river discharge and pollutant load in the Hyeong-san river watershed. The estimated annual average river discharge of Hyeong-san river flowing into Yeong-il bay is about 878.34×10/sup 6/㎥/year which is about 73% of annual average of total precipitation in Hyeong-san river watershed. The annual average of pollutant load flowing into Yeong-il bay was estimated each 15.11 ton-COD/year, 23.24 ton-SS/year, 10.65 ton-TN/year, and 0.54 ton-Tp/year. For the seasonal variation of pollutant loads, it was tended as increasing of river discharge as increasing of inflow pollutant loads at June and July of summer and October of autumn. The main source of pollutant loads was found to be the Pohang city and Pohang industrial complex which are located near the mouth of Hyeong-san river. Therefore, for effective water quality management of Yeong-il bay, the counterplan to reduce pollutant loads from the main source of pollutant loads is required.
