Lankan scientist aims for “zero sludge”

A Sri Lankan has come up with a novel proposal to achieve “zero sludge” in sewage treatment.
Tissa Meepe presented his innovative “Zero Sludge Sewage Treatment” paper at the 13th European Biosolids and Organic Resources Conference and Exhibition, held recently in Manchester, Britain.
Over the past 30 years, Mr. Meepe has been installing treatment plants manufactured by others for small and medium water and waste-water treatment systems.

Most of the sewage and wastewater treatment plants are for hotels, meat and fish processing organisations and the garment industry. Many of these plants are located in metropolitan areas where the neighbourhoods are highly sensitive and the land expensive. Mr. Meepe’s objectives are to minimise the size of the plants and reduce sludge generation or “zero”. He says the disposal of sludge can be a “smelly and cumbersome exercise”.

Mr. Meepe is the only Asian to have delivered a presentation at this conference. He is also a nominee for the Lee Kuan Yew 2009 Water Prize.
