CDE introduces AquaCycle water treatment technology - continued


Mr Peter Brewitt, CDE Business Development Manager for France, describes the co-operation process involved.

The process involved S.A. André Boureau working closely with our technical department to design a system suitable for processing their material.
      A detailed sieve analysis was carried out which enabled us to design a future proof system specifically for the quarry at Lanty-sur-Aube.
      The level of communication between Mssrs Jean-Charles Gillet, Jean-Jacques Boureau and ourselves, ensured we capitalised on the extensive experience of both parties.
      The level of interaction and shared knowledge involved in this project will benefit both companies long into the future.

The new plant consists of a M2500 E4 mobile washing plant and an AquaCycle A200 thickener.Purpose Built Solution

The new plant consists of a M2500 E4 mobile washing plant and an AquaCycle A200 thickener.

This is the first AquaCycle system in France for CDE. The plant has a capacity of 100 tonnes per hour and is processing 0-60 mm alluvial limestone material to produce a 0-4 mm washed manufactured sand as well as 4-8 mm and 8-20 mm washed grit. The retainings, 20-60 mm gravel, are crushed and reintroduced into the installation. The 0-4 mm sand product has been produced with maximum retention of +75 micron material and the efficient removal of -75 micron material.

The thickener significantly reduces the area required for ponds onsite at the pit and enables the recycling of more than 90% of the water used in the washing plant.

This leads to a substantial reduction in the volume of water that has to be provided for the system. Mr Jean-Charles Gillet, Managing Director of S.A. André Boureau, commented:

We are concerned with reducing costs, increasing efficiency and reducing our environmental impact. The AquaCycle system guarantees that we can achieve all three of these goals while complying with environmental requirements.

Another important issue for S.A. André Boureau is the health and safety of its employees and the solution has been designed to minimise spillage thereby ensuring a clean and safe site.

Mr Jean-Jacques Boureau, President of S.A. André Boureau, commented:

This is our first time using a mobile washing plant and the process with CDE has reassured us we have made the right decision.
     Their technical expertise, with our input, has guaranteed that we have a washing solution that fulfils our requirements. We were very impressed with the level of detail implemented by CDE to guarantee they delivered a system that was suitable for our needs.

S.A. André Boureau will celebrate its 50th birthday in 2015 and plans are underway to mark the special occasion with an open week event to give visitors an opportunity to visit the CDE washing plant and witness the new equipment in operation.
