Parkson Introduces a Patented THERMO-SYSTEM for Biosolids Drying Process

Parkson Corporation, a provider of water recycling and treatment solutions, has declared the inauguration of a patented THERMO-SYSTEM (Active Solar Sludge Drying System) in Noblesville Town, Indiana.

The new THERMO-SYSTEM includes two solar-aided chambers and a 145 kW auxiliary heating system to remove the moisture from the accumulated municipal sludge. The auxiliary heating system comprises water-to-air type of heat exchangers set all over the drying chambers, which use the surplus hot water capacity available from an installed plant boiler. The extra heat which was getting wasted before the installation of the system is used to improve the drying capability of the system by nearly 50%. The THERMO-SYSTEM removes nearly 75% of the water content from the sludge and makes them class A type of biosolid. The introduction of the system substantially reduces the spending on the disposal of sludge than the earlier method of disposing wet biosolids. Also, the use of sun energy makes the drying process cost effective than the conventional thermal dryers.

Michael Hill, Parkson’s Thermo-System Product Leader, said that the new Thermo-System Active Solar Sludge Dryer amply meets the requirements of the wastewater treatment plants and reduces their spending on handling biosolids. He added that the new fully automated system utilizes solar energy thus reducing the energy consumption costs and labor deployment costs and requires less spending than most of the traditional systems that utilize high temperature technology.
