Submersible mixers handle leachate for Cleanaway

Highly durable, custom-made mixers from Landia are helping Cleanaway, one of the UK's leading waste management companies, to treat successfully leachate at its Rainham landfill site in Essex.

One of only two landfills in the whole of the UK capable of receiving waste by river-borne transportation, this strategically important Cleanaway site is utilising Landia’s special-coated POD-I submersible mixers to suspend solids in two underground 160m3 leachate tanks.

Working to very tight confines, with
only a 6mm margin to spare, Landia custom-designed the POD-I mixers to fit the narrow access points of the Rainham site’s leachate tanks.
Able to withstand very harsh conditions, these two-component-coated, cast-iron mixers, all with 316 stainless steel submerged equipment, continuously agitate and homogenise to ensure that solids are not allowed to settle.

Operating around the clock, the 700rpm mixers have replaced aeration units that were no longer suitable for the high standard of leachate handling required by Cleanaway, as the company’s Environmental Scientist, Andrew Whiteman, explains: “Landia’s equipment is proving very reliable and effective at Rainham.

“We have every confidence in the long
term performance of these mixers which
meet our established, stringent criteria for
a highly engineered, professionally managed landfill site”.

He added: “Cleanaway recognise Landia’s considerable experience in providing top quality mixers and pumps for leachate, as well as the company’s impressive customer support”.

Cleanaway operates four regionally important landfill sites disposing of around three million tonnes of controlled waste each year. Three of the sites are located in the south east; the other is located in the Midlands.
