A company with strong values...Simon Moos Manufacturing A/S was established in 1978 by the current directors Simon Moos and Hanne Aamand. Th e knowledge gained over the years from the contracting division of Simon Moos has allowed our company to design, develop and produce equipment for the wet waste industry in particular their own series of jet-vacs and not to mention the well-known mobile and stationary units for the eff ective dewatering and treatment of sludge’s. We are an international company with over 60 employees and have an export share of 75% spread over three continents.

Simon Moos Manufacturing A/S is fi rmly rooted in the South of Denmark where there is a strong tradition in manufacturing and engineering. Here the major part of our product programme is being designed and produced. We attach great importance as an employer in the fact that our employees, whether he or she works on the shop fl oor, on the design and production team or with the sales department all share the same values, commitment and enthusiasm in producing top quality products for the industry. We attach great importance and take pride in our openness and our ability in understanding the market place. Our company’s keyword is, “balance”, balance between meeting the customers requirements and producing the right type of equipment to service their needs. A good indication that we are living up to our reputation and achieving our goals in being a leading force in the manufacturing industry is that we are able to boast re-sales to our customers of 95%. Th is fact makes our company very proud.

...a guaranteed investment for the future...”Th e increasing environmental impact must be disconnected from the economic growth.” Th is sentence will become a standard remark in any global or national environmental strategy.

Th e current situation with global warming, the rising amounts of waste being produced and the growing need to reduce it along with other sources of pollution has resulted globally in various political initiatives, the purpose of which is to change the attitude of waste companies and industry in obtaining a greater environmental awareness. In fi nancial terms companies will notice increasing costs for the disposal of waste water. Th e permitted limits for contaminants in waste water will become lower and lower. Fuel, road tax and disposal along with clean water supplies etc. will eventually become subjected to higher environmental duties. If companies are unwilling to adapt to changes in environmental legislation they will probably notice a marked reduction in profi ts. Using the AVC system in certain circumstances could reduce or even waiver the current landfi ll duty within the United Kingdom. Th e Simon Moos AVC system fi ts the global environmental strategy because it reduces waste volumes by up to 90% and in many cases the dry fi lter cake produced can be safely disposed of at a licensed landfi ll site or recycled and used as fertilizer aft er a controlled sanitation process to name but a couple of routes.

Th e keyword in the company is balance.

90 % volume reduction and 95 % reduction of COD and BOD - only a few of the advantages of the AVC & EOD/DOD system ! It dewaters the sludge to a dry mass with various recycling possibilities!

Realising that the average sludge contained a high percentage of water, which was needlessly being transported for disposal at the local waste water treatment works, Simon Moos decided to develop a system that would take the treatment works to the sludge and the AVC & DOD/EOD where born. Th e principle behind the MOOS AVC & EOD/DOD system is to deliver a high “volume reduction” of sludge. Th e EOD/DOD is a pumping and polymer dosing unit. EOD is the electrical driven construction and the DOD is a diesel engine version.

Th e EOD/DOD pumps the sludge into the AVC dewatering container where the separation of the water and dry matter occours.

Th e EOD/DOD unit is used to mix polymer into the sludge as it is being pumped into the AVC de-watering container. Th e mixing of polymer into the sludge creates a fl occulation that increases the speed and effi ciency of the de-watering process.

Under normal circumstances the sludge is drawn into the EOD/DOD by the sludge pump located on the EOD/DOD and then polymer is injected automatically at a suitable amount by the polymer pump and injection system of the EOD/DOD.

Th e user can easily regulate the actual amount of polymer injected by adjusting the speed of the polymer pump.

Th e sludge can also be delivered directly into the EOD/DOD from a pressurised tanker, where the polymer is then injected into a Cyclone system attatched to the EOD/DOD. Th is function is particularly useful if the sludge contains crude debris such as stones, heavy sand and metal etc. which would normally damage the sludge pump. Th e fl occulated sludge continues from the cyclone and in to the AVC where separation of water and dry matter occurs.

AVC translated means, on-site dewatering container. Th e AVC is a dewatering unit constructed as a mobile container. Th e AVC consists of a closed container, equipped inside with fi ltration screens. Th e fi ltration screens drain and de-water the fl occulated sludge. Th e front of the AVC is equipped with a fi ller pipe through which the container is charged with sludge. Th e reject water is discharged through valves on the front of the AVC. Th e rear of the AVC container is equipped with a full width door, through which the de-watered sludge is emptied.

It’s simple to operate...

• Delivers a high volume reduction of up to 90%.• High dry matter percentage in the dewatered sludge

Product description for the AVC...Th e AVC consists of a closed container, equipped inside with fi ltration screens along the two sides and a fi ltration screen down the centre. Th e fi ltration screens drain and de-water the fl occulated sludge.

Th e rear of the container is equipped with a full width door with a hydraulically assisted locking mechanism, through which the de-watered sludge is emptied.

Th e front of the container is equipped with a fi ller pipe through which the container is charged with sludge. A pivoting galvanized ladder is mounted at the front of the container and when drawn down erects a galvanized safety rail which allows easy and safe access to the top, where the inspection hatches are located.

Th e cleansed water is discharged through two 3” ball valves, one on each side. Th e container is equipped with an inside ladder for easy access for cleaning and inspection. Th e container is sandblasted, primed and painted. Th e inside surface is coated with epoxy.

and the EOD/DOD!Th e EOD/DOD unit is used to mix polymer into the sludge as it is being pumped into the AVC de-watering container.

Th e mixing of polymer into the sludge creates a fl occulation that increases the speed and effi ciency of the de-watering process. Th e polymer feeding/dosing pump accomplishes the process of mixing the right quantity of polymer into the sludge and the polymer pump is self-priming.

Th e screw pump is used when the application for pumping sludge from the source into the AVC de-watering container is required. Th e cyclone is required when the application requires the sludge to be discharged directly into the AVC and allows the loading of sludge’s containing crude debris to be loaded into the container from a normal vacuum tanker. Th e polymer supply for the feeding/dosing pump is stored in a tank. Th e mixing device in the tank creates a homogenous polymer mixture. An access hole is provided for cleaning the tank. A control panel is provided for the operation of the sludge pump, polymer pump and mixing propeller, as well as all start/stop operations. Th e pump/cyclone and dosing plant is sandblasted, primed and painted.

Recycling of dewatered sludge...Th ere are several routes for recycling and disposing of the dewatered cake from the AVC system. Depending on the specifi c nature of the dewatered cake it can either be lime stabilized and used as fertilizer on agricultural land, composted or used in biogas plants. With a MOOS lime/ sludge mixing plant dewatered sludge is mixed with lime. Th e pH level is raised to 14 and you obtain the optimum temperature of approximately 80° C. Th is gives an eff ective sanitation and delivers a log 6 reduction in pathogens.

Grease or contaminated cakes can be used to accelerate the burning process at incineration plants or as a last resort be deposited at a landfi ll site. In addition to the fact that we construct eff ective sludge dewatering systems it is also one of our strengths at Simon Moos Manufacturing that we are able, through the contracting division of the company, to off er advice and technical support in the handling of sludge’s from the knowledge and experience gained over many years.

...and quality cleansed water!During the dewatering process the fl occulated sludge captures harmful particles and holds them within the dewatered cake. Th is means that the cleansed water is of a high quality and can be reused. Th e AVC is unique in its performance as the reduction values show in the table below. In some cases a further reduction of the very small percentage of suspended solids in the permeate is necessary. Th e solution may be be a mechanical fi lter – sand fi lter – charcoal fi lter, UV or UF. It depends on the specifi c case and the purpose for reuse of the water. Th e core in our dewatering system is that we can deliver a fl exible and economic solution - fulfi lling legislative requirements!
