For Municipal Wastewater and Water Treatment, Geotube Dewatering Technology Works - Case Study
For municipal wastewater or water treatment facilities, efficient dewatering can be a challenge. Space issues, personnel, and cost are all considerations, and an operation may experiment with a number of techniques before finding one that works. But dewatering technology from TenCate Geotube is proving to be a simple, cost-effective solution. Geotube2 dewatering technology has been used for a ...

Growth of microalgal biomass on supernatant from biosolid dewatering
The paper reports the results of an experiment to assess the feasibility of including a photobioreactor within the design of a wastewater treatment plant, growing microalgae on the centrate from anaerobic sludge dewatering. The growth of algal biomass would take advantage of the available nitrogen and provide a substrate for biogas production by anaerobic digestion. Tests were carried out by ...

Combined experiences of thermal hydrolysis and anaerobic digestion – latest thinking on thermal hydrolysis of secondary sludge only for optimum dewatering and digestion.
ABSTRACT The basic principles of batch thermal hydrolysis process (THP) are well known as a pre-treatment to anaerobic digestion (AD) . Early work done in the 70s in the USA and the 80s in Japan demonstrated the optimum time and temperature for thermal hydrolysis being 340 F for 30minutes. These principles have been put into full practice in 20 plants around the world at plants ranging from 5 ...

The Connection & Difference between Low Temperature Sludge Drying and Ordinary Sludge Drying
The sludge drying technology has an early origin. In the early 19th century, the Germans invented the world's first plate and frame filter press. Today, after two hundred years of development, various types of filter presses have been born for different scenarios. The domestic sludge drying industry started late, sprouting in the period of reform and opening up in the late 1970s. Due to the ...
