Acorn Recycling has two types of dewatering equipment which can carry out in situ sludge dewatering on urban waste water treatment plants, industrial plants, septic tanks, aeration basins, lagoons and specialised works.  Acorn provides a complete service with all its equipment including, set-up, operation and sludge disposal.

MASKOFLEX Mobile Dewatering Unit

The Maskoflex mobile dewatering unit is ideal for dewatering wet sludges (1-5%) within small to large sized treatment plants and septic tanks. With the sludge automatically loaded on board, the Maskoflex can then easily transport the dewatered sludge (12-18% dry solids) to the disposal destination.Because of the reduction in volume and efficiency of dewatering, the Maskoflex mobile dewatering unit can dramatically reduce the costs of sludge disposal.

MASKOZOLL Containerised Dewatering Unit

For larger municipal and industrial treatments it might be necessary for an on-going sludge dewatering system to work continually to dewater the sludges produced. A static containerised MASKOZOLL unit can be used in a wide range of industrial applications.This patented system, exclusive to Acorn Recycling in Ireland, works in the same way as the mobile dewatering unit above but is available in a variety of sizes to meet any requirement. This system has been used in the food and drink industry and paper pulp industry, as well as for wastewater treatment sludges. Acorn recently installed a large unit in a meat processing plant that treats 75 cubic meters per hour.

Maskoflex 312

FilterBox system.

This has a polymer system attached which doses the sludge inline. Once it reaches the filterbox it settles and separates out. The water is then ejected through the membrane sidewalls of the filter box after a number of hours. The filterbox can be filled a number of times before the sludge cake needs to be transported. This system can increase the solids from 1-5% DS to approximately 9-12% DS.

Training for this unit is 1 day. This unit is ideal for small/medium sized sewage plants as a cost effective alternative to bulk removal of sludge. We have found this unit to be particularly suitable for replacing drying beds as a means of sludge drying. The unit will dewater 100-150 cubic meters of sludge before the unit requires emptying. Once full it is removed by hookloader and the waste transported directly to the disposal facility. The unit is cleaned and returned for continued use.

Other products and services from Acorn Recycling


Packaged Waste Management | Acorn Recycling

The unit has been used in applications as varied as extracting saline solution from plastic containers, paint from tins, aluminium cans, waste water treatment plant screenings, Tetra packs and oil drum containers. It is also capable of removing water content from primary screenings from urban wastewater treatment plants and wet food products such as fruit and vegetables.


Composting | Acorn Recycling

The composting process employed is highly controlled process that ensures compliance with a range of relevant standards, including EPA compost quality requirements and Department of Agriculture animal by-product treatment. Acorn Recycling operate a network of indoor forced aeration composting facilities capable of treating a wide range of biodegradable wastes. Food and Drinks industry sludges and residue.


Centrifuges | Acorn Recycling

The liquid passes into a separation chamber where centrifugal forces separate the solid from the liquid.The solid is flung on to the bowl wall and are fed through the scroll into a discharge and onto a conveyor. It can produce a cake of greater than 21% DS which significantly reduces the volume of water for transport and produces a centrate that is clear enough to discharge or return to the headworks or sludge tank.


Services | Acorn Recycling

In addition to composting Acorn provides; mobile de-packaging unit for packaged products, sludge dewatering services utilising fixed and mobile plant and disposal of water treatment sludges. Acorn use these range of technologies to find the most cost effective and environmentally sound methods for the disposing of biodegradable wastes.
