Oil water separators are equipment used to separate oily waste materials from wastewater streams. They are typically mounted in industrial and maintenance areas involving petroleum, oil, and lubricants. They separate the oils from the waste water at low concentrations.

An Oil Water Separator (OWS) is one of the parts of shipboard equipment that is used to separate oil from the bilge water before discharge overboard. Oily water can be found onboard of every vessel. Bilge water that came from places and equipment near the shipboard contain oils, and if directly discharge will make the marine environment dangerous and dirty. Oily water should be drained first to the bilge tank and has to be treated in an oil water separator before discharge so as not to pollute the marine environment. An international agreement under MARPOL states that vessels need to have oil water separator to remove oil contaminants before disposal overboard.

There are different types of oil water separator used in marine. First is the Gravity Plate Separator. It contains a series of oleophilic plates wherein the contaminated water flows. The oil in the water coalesces on the underside of the plate and then from droplets before turning into liquid oil which then floats off the plate and accumulate at the top of the chamber. The oil collected on the chamber is then transferred to waste oil tank on the vessel where it will be discharged to a treatment facility. This kind of separator is commonly used by ships.

Second is the Electrochemical oil separator. It involves the use of electrolyte bubbles to attract pollutants and carry them at the top of the treatment chamber. After accumulation, the oil and other pollutants are transferred to a waste oil tank.

Third is Bioremediation. Bioremediation uses microorganisms to treat contaminated water. In their researches, this was used as one time multi purification process since it was able to remove the majority of the contaminants and treat pollutants at a very low concentrations including organic contaminates. After the treatment, only water, carbon dioxide, and an organic sludge were left.

Last is the Centrifugal water-oil separator. It is a device that separates oil and water through centrifugation. It contains a rotating cylindrical container inside a larger stationary container. They are used for waste water processing and for cleaning oil spills. Also, it is used in filtering diesel, and purifying lubricating oils.

RWO has been the world leading supplier of Oil Water Separators. Because of the excellent performance of their OWS, more than 15,000 ships have been equipped with their equipment. They have been complying with the IMO Resolution MEPC 107 (49), 5ppm standard, compliance with regulations of Maritime and River Registers, and compliance with the requirements of doctrine for the prevention of pollution of inland waterways during vessel operation RD 152-011-00 since 1978. They are using the combination of highly effective open porous coalesces and second stage emulsion breaking oil and hydrocarbon polisher. Their Oily water separators are the most compact. It is suitable for news builds and retrofit. Also, installation and maintenance is very easy. RWO’s OWS conducts regular checkups to ensure that second stage is bypassed whenever possible that makes it economical. And last, RWO assures that their OWS are most safe because of their oil monitoring devices.

Nowadays, observing the adage that “the customer is always right” no longer cuts it. Product quality, customer satisfaction, impressive aftermarket services are no longer enough to be competitive or to maintain even a small, loyal customer base. In Singapore, more and more corporate gift companies are beginning to realize the importance of corporate gift-giving in establishing stronger relationships with both employees and clients. The gestures of giving has become a staple of corporate operations such that it has become an ‘art and science’ all its own. Today, special strategy of ‘giftology’ is considered a special commercial function and companies devote tremendous resources into this process.

Singapore companies, big or small, now frequently giving out gifts to employees, clients, and even suppliers not just in special occasions or holidays like Christmas but for simple functions like company foundation days and company activities like sports fest and even for personal events like birthdays. For employees these business corporate gifts are simple testaments that they are valuable in a company and are assets that the company protects. Instead of simply giving awards or commendations for doing a great job or for staying with the company for so long, premium corporate gifts communicate the companies appreciation for the work put in by employees and sends the message that the companies acknowledges every individual in the office regardless of position or job. As such, these gifts boost employee confidence and morale and further encourage them to work harder than before. Most Singaporean companies believe that, if done properly and effectively, a vast array of opportunities can arise for the company

Among clients, suppliers and consumers in Singapore, business gifts hold symbolic functions and express a company’s appreciation for their patronage. At the same time, corporate gifts also generally serve as a marketing strategy and a major public relation instrument. Recent study shows that companies pay a lot of attention in considering what to give out. There are numerous business gift-items to choose from alternatives. But there are creative alternatives. Corporate gift items in Singapore like shirts and coffee mugs can be more creatively and boldly improved through packaging and timing. This means additional care for materials and processes. Shirts, mugs, pens and notepads are staple corporate giveaways simply because these are items that clients and customers use every day and are therefore popular due to practical value of products. Recently, USB, earphones, cellular phone covers, power banks, mobile speakers, and other techno products have become daily necessities and have ideal corporate gift items.

Also, traditional Singapore corporate gifts  like shirts and jackets must not only be useful for office or everyday use but must also fit newer lifestyles like outdoor recreation trends. Dri-fit materials, hooded jackets, sweatshirts can all be used casually on a daily basis   but they are also appropriate for running, jogging and other physical activities. Although the item need not be expensive, they must be of high value. Novelty and handmaid bags and table paraphernalia are not necessarily expensive corporate gift ideas but they are not typically mass produced items and are therefore high value. Personalized corporate gift items also appeal to that sense of being distinct.
