Eco Solids Announces First Sludge Treatment Plant In China

Eco Solids International is about to witness completion of its very first sludge treatment unit built in China under a groundbreaking agency arrangement

The manufacture of this inaugural Eco-Solids Process in Shenyang, signals the start of a potential 20 further units to be built over the next three years as economic growth and wastewater infrastructure increases in Liaoning and the North Eastern provinces at one of fastest rates in the whole of China.

The culmination of the first Eco-Solids Process system in Liaoning follows the signing of a major licensing agreement with leading water and environmental equipment company Shenyang Yinuo Science and Technology Company (‘Yinuo’) in north east China.

“As the Chinese look to improve sludge management, recycling and greenhouse gas emissions, we have proved that with the right technology and a patient but determined approach, it is possible to get to the heart of a major market,” said Eco-Solids International’s Managing Director Clive Rigden.

“Watching the finishing touches being made to our first Eco Solids Process system in China is an exciting and very rewarding moment for us”, he added.
Using patented, advanced lime stabilisation treatment technologies first pioneered in North America, Eco-Solids International (based in Hampshire, UK) has the exclusive worldwide rights outside the US to the sludge treatment process – and also has plans to establish the Eco-Solids Process in the Middle East and India.

A continuous stabilisation process for treating all types of sewage sludge, including sludges that contain a proportion of hard to handle Surplus/Secondary Activated Sludge (SAS), the Eco-Solids Process produces an enhanced treated biosolid and income-generating product (which exceeds European and U S regulatory requirements).

It also results in significant reductions in sludge volume, volatile solids (VS) and odours, whilst retaining non-leachable nitrogen and phosphates. Complete inactivation of microbiological activity is also achieved, as well as an improved percentage of solids of the product.
