Using the MOOS lime stabilization unit results in a very efficiently sanitized end product, which has a markedly improved consistency. Lime stabilized sludge can be re-used to improve soil quality and is a valuable fertilizer.
The MOOS lime stabilization unit is mounted on a CHEM spec Roll-on-off frame for easy transportation. The unit contains 2 sets of chains each with 24 lamellas whose job it is to convey the sludge to the rear of the unit and into a mixing worm where the lime and sludge are efficiently combined together. From the mixing worm the combined lime and sludge is then conveyed to a discharge worm where the mixture is deposited either into a container or onto the ground.

Spreading of none sanitised sludge on agricultural land could in certain circumstances cause serious cases of infection in both humans and animals. Therefore, sanitising the sludge using a mixture of lime has become more and more widespread. Environmental legislation in most areas states that sewage sludge has to go through a controlled sanitation when it is to be used for example as a soil conditioning/fertilizer on farmland. With this in mind Simon Moos Maskinfabrik A/S has developed a very efficient plant for the sanitation of dewatered sewage sludge through lime stabilization.
Documented test results on the MOOS lime stabilization unit show that if sludge is mixed with hydrate lime Ca(OH)2 the pH-value is raised to above 12 on condition that the added amount of hydrate lime corresponds to 50% of the dry solids content. For example if we take sludge with a dry solids matter of 20% you then add about 100 kg hydrate lime per ton of sludge. The combined effect when adding this quantity of hydrate lime to the sludge is that the pH-value is raised to the desired level and is maintained for up to 3 months as well as increasing the temperature of the sludge to about 80°C. The combined effect of increasing the pH level and raising the temperature of the sludge gives a log 6 reduction in pathogens and results in a sanitised cake. Obnoxious smells are also reduced.
With the MOOS lime stabilization unit you obtain a complete sludge sanitisation that complies with current legislation, one of which meets the conditions for re-use of the sludge as a valuable fertilizer/soil conditioner on agricultural land.
Efficient: A MOOS lime stabilization unit mixes the sludge and lime together very efficiently which is the basis in obtaining an optimum sanitised sludge.
With over 30 years of know how. The Simon Moos group not only produces equipment for the wet waste industry globally but also has a contracting side to the company which was started in 1977. The know how gained over the years from this side of the group has been incorporated into designing and manufacturing first class products for the industry. Some of the conditions we impose on ourselves when producing equipment are that they have to be well constructed, efficient, easily operated and built to last. This not only applies to the MOOS lime stabilization unit but to all the equipment we produce for the treatment of sludge’s that includes the Simon Moos range of mobile dewatering units.
Valuable fertilizer: Using the MOOS lime stabilization unit results in a very efficiently sanitised end product, which has a markedly improved consistency. Lime stabilized sludge can be re-used to improve soil quality and is a valuable fertilizer.
