History of Simon Moos dewatering

Simon Moos is a Danish company established in 1978, leader in developing and manufacturing equipment for the dewatering and filtration of sludge from any kind of industries. 

The concept come from 1950 and has been improved to treat in the cheapest way WWTP everywhere in the world.

They exist models all over the world design and modify to suite the specific needs size of work (15000 ha or resort wontbe the same 🙂 emergency coalashe treatment afetr 50 yeasr dumping as well ).

The know-how gained from nearly 43 years of experience in handling and treating sludge from septic tanks, wastewater treatment plants, grease traps POME from palm oil, car washes paper industry from Sweden and chemical industries from Germany give the chance to supply our machine to all continents from small and large companies.

40 trucks version KSA in India, 50 AVC containers in New-zeland 2 truck made in europe SCANIA in LOME Togo etc  morethan 3000 units soldto smallwaste collector of septic tank gullies and small factories  up to Suez Veolia Chemical leader Evonik Dow corning…


roles of the machine

2 Family exists in our company : THE AVC & KSA  (container version & truck version in 16 19 26 tons) special ASIAN model light truck exist Indian chassis etc.

The AVC is designed based on a container and its easily transportable and scalable solution for any overloaded WTTP, petrol station contaminated soil, dioxin lakes and ponds treatment (treat solid sludge its cheaper than 95 %humid!), coal ashes which pollute take huge area etc.

The system works by adding a coagulent  and or flocculent to the sludge. During the highly efficient mixing step, the polymer separate the water from the sludge causing with fixing contaminent into the sludge.

For all solid liquid separation we need chemical electricity or force, we chose chemical with the best suitable specification to-match the best ratio sludge dryness Vs water quality and volume of sludge created.

The main point is chosen by the need of customer of course

The special filtering structure allowed us to get more water out than other filter and so be able to fast option of reloading the container which increase the capacity of around 300 m3 before empty it (tss 5%) 

the average of septic tank 95 % or textile industry pr paper will give us based on TSS and other parameter different refilling capacity/day 

The sludge are dry up inside and form a cake during this time cleansed water is returned to the source of pumping or at further step of WWTP.

In recent years the KSA-& AVC system has been redeveloped to handle sludge from oil refinery processes, car and commercial vehicle washes, garage forecourt interceptors, gullies, and mixed industrial Zone waste environmental emergencies canal dredging etc.

We provide multi-purpose dewatering equipment for a variety of applications including dewatering industrial waste mixed zone, biogas digested sludge, livestock waste, paper industries, tunnel digging fondation drying process, quarries sludge recycling, grease trap treatment, lagoon sludge, and paint booth….

The container is of course scalable and we have the chance to have one available in Vietnam since  11th sept. 2020

The AVC dewatering tank

The AVC has been exported last 50 years until 45 countries and more than 3100 customers daily used it. 

From Carlson Wagon lit to Evonik, SOS vidange,  Suez Veolia, Cemex or the Big Oil and gas company in Norway or Martinique, The city of Mumbai and Senevie From Togo use to clean domestic and industrial waste. Artelia advise this solutiion for OLI and GAS plant in scandinava since the weather condition  and the special needs in remote area are super high.

The high-efficiency polymer dosing and mixing allow us to use 500gr to 800gr of polymer per tank, which treats about 250 300m3 of liquid waste at 95% humidity.

Made in Denmark and setting up a large production in Vietnam to supply as much as possible the need to treat industrial waste at low cost.

The special media is easy to clean after emptying the container.

The AVC and dewatering mobile systems work like belt press in batch with more capacity of dewatering since the hole of the filter is bigger than the belt press

The main point is the right chemical for the right nature of waste.

The systems like other needs the adaptation for the dosing of polymer

The time inside the tank will give you more dryness as a filter press or belt press his speed will change the result.

Parameter Reduction systems average with suitable Chemical pure and to 50-50  sludge volume dryness and water quality :

  • The fact that the sludge volume has been reduced by a min factor 10
  • We eats grease traps! oily seafood transformation plant
  • Is a great tool in removing algae, silkweed and duckweed from choked canals, ponds and other waterways.
  • Relieving the pressures on small waste water treatment plants / satellite
  • avoid removing the effluent  by tankers (fuel, time, mileage, risk, etc ).
  • The systems also works very well on larger treatment plants when extra box capacity is needed to increase the pumping capacity up to200m3 per hours 1000m3 since its scalable .

Why the Simon Moos's AVC?

Economical benefits

Economically the KSA-AVC system has a low operating cost due to it being able to stay out in the working area longer without having to be discharged, reducing the time traveling to and from disposal sites. The system is fully automated and can be operated manually or by a radio remote control which allows for a one-man operation of the unit and together with its large volume reduction makes for huge savings on fuel, running and disposal costs.

less time needlessly transporting water. the operator is able to re-use the water for functions such as jetting drains and washing down, re-priming forecourt interceptors, car washes, and septic tanks. This eliminates the need to use mains water.

The Simon Moos AVC-System – a mobile roll-on-off dewatering container mainly used to dewater larger volumes of sludge especially from wastewater treatment works, oil refinery processes and effluent lagoons which include mine water, slaughter house, tannery and sludge produced from the food industry to mention a few.

The AVC-system is used in conjunction with EOD dosing unit which flocculates the sludge and delivers it to the dewatering container, either via a sludge pump or in the case of sludge containing crude debris such as stones, etc via a cyclone system.

There are several routes for recycling and disposing of the dewatered cake from the AVC system. Depending on the specific nature of the dewatered cake it can either be lime stabilized and used as fertilizer on agricultural land, composted or used in biogas plants.

The Simon Moos OAVC System – a mobile oil skimmer for treating oil-contaminated water and emulsions which can be combined with our Ultra-Filtration unit for extra water purification.

There are several routes for recycling and disposing of the dewatered cake from the AVC system. Depending on the specific nature of the dewatered cake it can either be lime stabilised and used as fertiliser on agricultural land, composted, or used in biogas plants.

And you can get very clean water like this: Parameter Reduction AVC :

– Suspended solids (SS) 95 %
– COD-BOD 95 %
– Total-phosphate (P) 60 %
– Total-Nitrogen (Tot-N) 67 %
– The fact that the sludge volume has been reduced by a factor of 10
– The KSA eats grease traps!
– The KSA is a great tool in removing algae, silkweed, and duckweed from choked canals, ponds, and other waterways
– WWTP Over the years the KSA has played an important part in relieving the pressures on small wastewater treatment plants and satellite works where traditionally the effluent was removed by tankers. The KSA also works very well on larger treatment plants when used in conjunction with the Simon Moos AVC system.
– Gully emptying The traditional way of emptying gullies is with a gully sucker. Once full the gully sucker decants its dirty water down the last gully to be cleaned allowing the contaminated water to eventually find its way into a watercourse and depositing solids in the drainage system which will need additional cleaning at a later date.

These models are second-hand and are available to try a test on-site contact us for more information.
