Simon Moos Maskinfabrik A/S

Model AVC/EOD/DOD - On-Site Dewatering Unit

1

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 an on-site system that would take the treatment works to the sludge and the AVC & DOD/EOD where born. The principle behind the MOOS AVC/EOD/DOD system is to deliver a high “volume reduction” of sludge. The EOD/DOD is a pumping and polymer dosing unit. EOD is the electrical driven construction and the DOD is a diesel engine version.

The EOD/DOD unit is used to mix polymer into the sludge as it is being pumped into the AVC de-watering container. The mixing of polymer into the sludge creates a flocculation that increases the speed and efficiency of the dewatering process. The EOD/DOD pumps the sludge into the AVC dewatering container where the separation of the water and dry matter occours. The AVC consists of a closed container, equipped inside with filtration screens. The filtration screens drain and de-water the flocculated sludge.

EOD - Electrical Pumping & Dosing Unit

The EOD is a electrical driven pumping and dosing unit used to mix polymer into the sludge. Power: Electrical(EOD). Sludge pump: Allweiler, 30 m3/h or 40 m3/h. Cyclone: 40 m3/h. Polymer pump: Allweiler. Polymer mixing device: 800 rpm. Polymer tank: 850 liter. Length: 2800 mm. Width: 1430 mm. Height: 1380 mm. Combined with our AVC – dewatering unit the EOD provides an excellent on-site dewatering unit.

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

The 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. The 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.

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

Empty weight: 6600 lbs (3000 kg) Volume: 7400 US gal. (28.0 m3)
Lenght: 21.50 ft (6552 mm) Width: 8.20 ft (2500 mm) Height: 8.45 ft (2576 mm)

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

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

The screw pump is used when the application for pumping sludge from the source into the AVC de-watering container is required. The 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. The polymer supply for the feeding/dosing pump is stored in a tank. The 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. The pump/cyclone and dosing plant is sandblasted, primed and painted.

Based on 30 years of experience within sludge dewatering and production of mobile sludge dewatering systems the AVC system has proven its strength many years ago!

We have chosen to show some examples that illustrate how our customers are using the AVC system for sludge dewatering - in very diff erenct circumstances ! From dewatering of primary-, biological or digested sludge from a WWTP to dewatering sludge’s from an oil refi nery surge pond!

The AVC system is ideal for dewatering wastewater produced in many industrial processes. The AVC has in practice proven that it is an excllent choice for dewatering of sludge from a palm oil mill to fl y ash from cooling towers!

Whether it’s to service routine contracts or industrial processes the AVC system delivers substantial savings in disposal and transport costs as well as a lower environmental impact!

There 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. The pH level is raised to 14 and you obtain the optimum temperature of approximately 80° C. This 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.

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. The 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. The 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. The core in our dewatering system is that we can deliver a fl exible and economic solution - fulfi lling legislative requirements!

You can always call us for support, questions etc. and we have all the neccesary competance in-house.

The MOOS group consists of several divisions with specific core expertise in sludge handling and water cleansing, either with a focus on construction or service. The interaction between employees gives an environment where ideas and feedback in total give you as a customer a competent partner in sludge handling and water cleansing systems.

The AVC is successfully operating on 3 continents! The picture above is taken in the Rocky Mountains!

The AVC has been sold to more than 20 countries around the world. We believe that the successful expansion of the Simon Moos brand is attributed to a highly motivated work force who constantly strive for perfection. We did not capture a new geographic market from a concept, but from a first class product. We as a company have an open approach to our customers and the market place; this is a part of the Danish culture. This fruitful approach to our way of doing business has resulted in continuous product development where we have combined the best ideas from our engineers and designers with input from our customers worldwide. This is the core of our business!.

EOD/DOD can be integrated into the AVC dewatering unit!

We can deliver the AVC & DOD/EOD in a construction where the EOD/DOD is integrated into the AVC dewatering container, so it becomes one unit! This is a perfect solution where the system is placed permanently at one location etc.
