AFECO gains NIC EIC accreditation

Building on a the development of our electrical engineering and installation capability and expertise, AFECO has successfully gained accreditation by the NICEIC.

NICEIC (National Inspection Council for Electrical Installation Contracting) provides assessment and certification services for contractors involved in electrical work and regulates the training and work of electrical enterprises in the UK. The NICEIC is one of several providers given Government approval to offer Competent Person Schemes to oversee electrical work within the electrical industry.

AFECO has been growing and developing their electrical engineering capability throughout 2017 and becoming an NICEIC approved contractor demonstrates the success of this growth. As part of the approval process, NICEIC assessors reviewed a sample of AFECO’s installation work, the Company’s premises, documentations, equipment and the competence of key supervisory staff. This assessment will be carried out on a regular basis going forward to ensure compliance is maintained. AFECO are now able to offer a complete electrical engineering service, from design through to installation, testing, commissioning and certification.

NICEIC is the UK’s leading voluntary regulatory body for the electrical contracting industry. It has been assessing the electrical competence of electricians for nearly sixty years and currently maintains a roll of over 26,000 registered contractors. NICEIC has developed a reputation amongst consumers, specifiers of work and industry for promoting safety, integrity and technical excellence. Contractors undergo a rigorous assessment process, covering a representative sample of their work, their premises, documentation, equipment, and the competence of their key supervisory staff. They are then re-assessed on a regular basis to ensure continued compliance.

AFECO in the press: the importance of alkalinity for wastewater treatment

Building on a series of technical articles written by AFECO specifically for Superyacht Technology magazine on marine wastewater treatment, the latest edit written by the AFECO technical experts explains the importance of alkalinity in biological wastewater treatment.

In the operation and smooth running of a biological sewage treatment plant (STP) one of the parameters which is most often overlooked is alkalinity. Our article looks at what alkalinity is, why it is especially important for on board systems, and what can be done to ensure that everything works as it should.

Biological systems are very sensitive to the pH of the solution in which they are in. Species such as proteins and enzymes will only work properly within a very narrow range of pH values, and can be very susceptible to any changes in pH. Biological wastewater treatment systems in STPs are no different. The bacteria and enzymes which treat the wastewater are also sensitive to pH, and operate most efficiently within the pH range 6.8 to 8.0. The biological wastewater treatment process also generates hydrogen ions, and so alkalinity is needed to keep the pH of the solution in the required range. If the alkalinity is too low then the extra hydrogen ions are not removed, the pH drops, and the speed of the wastewater treatment slows or even stops. If the STP is nitrifying too (converting the ammonia in the wastewater into nitrates) then this process will also consume alkalinity.

This makes it even more complicated, as not only is it does the user need to know the alkalinity of the wastewater prior to treatment, it is also helpful to measure the residual alkalinity of the treated wastewater. The leftover alkalinity is a useful measure of whether the STP’s biological processes are working efficiently.

Alkalinity in natural water comes from the soil and rocks, which the water passes through prior to treatment. This means that the alkalinity present in shore water will vary depending on the geology of where the shore water was treated. It also means that when a vessel changes from shore water to water produced on board (through reverse osmosis), the process will remove the majority of the alkalinity from the water. This has a dramatic effect on the pH, and therefore the performance, of the STP.

As any discharges from a superyacht must comply with MEPC.227(64), this process could also mean owners are breaking the law if not aware of its effects. MEPC.227(64) states that ‘The pH of the samples of effluent taken during the test period should be between 6 and 8.5.” Ensuring an adequate alkalinity concentration in the wastewater will enable the pH to be kept within this range, and so will keep any discharges compliant with the legislation.

AFECO in the press: technical solutions to dumping wastewater in ports

Recognised as the go-to industry experts for wastewater treatment in the marine sector, AFECO have recently published an experts article for Superyacht Technology on the alternatives to dumping wastewater in ports.

The article explains the different types of wastewater generated on board superyachts: black water and grey water. Black water is wastewater and sewage from toilets. Grey water in the wastewater from baths, sinks, laundry and kitchen which can include fats, detergents and chemicals. Both types of wastewater can damage ecosystems if discharged into aquatic environments.

The challenge facing vessels is how to handle and treat these waste waters in the most environmentally sensitive yet cost effective manner whilst ensuring compliance with relevant legislation.

The treatment of these wastewaters is the subject of a number of MEPC (Marine Environment Protection Committee) resolutions but knowing how to effectively meet these requirements can be challenging. For a start, there are numerous suppliers of wastewater treatment systems and knowing which one would be best suited to your vessels requirements and operation can be a challenge. Secondly, understanding where you are permitted to discharge treated wastewater overboard and the costs of disposing of these wastewaters whilst in port can impact the operational costs of a vessel.
