Microalgae growth for nutrient recovery from sludge liquor and production of renewable bioenergy
Proof-of-concept has been demonstrated for a process that will utilize nutrients from sludge liquor, natural light, and CO2 from biogas to grow microalgae at wastewater treatment plants. This process will reduce the impact of returning side-streams to the head of the plant. The produced algae will be fed to anaerobic digesters for increased biogas production. Dewatering of anaerobically digested ...

Screw Press Machine in Fruit and Vegetable Waste Management
A screw press machine plays a crucial role in the efficient and sustainable management of fruit and vegetable waste. As the global population continues to grow, so does the demand for fresh produce, resulting in higher levels of waste generated in the fruit and vegetable processing industry. In this context, the screw press machine has emerged as an innovative solution for reducing waste volume, ...

Influence of chemically enhanced primary treatment on anaerobic digestion and dewaterability of waste sludge
To lower energy consumption at a sewage treatment plant (STP), primary settling could be enhanced to direct more chemical oxygen demand (COD) to anaerobic digestion (AD) for increased biogas production and decreased aeration. Primary settling can be chemically enhanced by applying flocculation aids (FAs). FAs are refractory compounds that may affect all sludge treatment facilities. In this ...

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 ...

New processes for the improvement of sludge digestion and sludge dewatering
INTRODUCTIONThe examination of numerous sewage sludges from municipal wastewater treatment plants leads to the conclusion that on the one hand dewaterability of these sludges worsens and that on the other hand dewaterability of sludges becomes more and more important due to increasing disposal costs. Especially wastewater treatment plants with inflows from the food processing industry often face ...
