Understanding sludge rheology and optimizing equipment performance is crucial for energy efficiency in wastewater treatment plants (WWTPs). This study examined sludge rheology after thermal hydrolysis pretreatment (THP) at 60, 80, and 120 ◦C for 2 h, followed by anaerobic digestion (AD) at 37 ◦C for …

Hittemetingen, belevingsonderzoeken en een simulatiestudie geven inzicht in hitte oorzaken en effectieve maatregelen tegen hitte in typisch Nederlandse woonsituaties.

High population growth, a lack of wastewater treatment plants and poor wastewater management are major challenges in wastewater management in Timor-Leste (East Timor). One of the approaches of the government of Timor-Leste is to separate wastewater into greywater and blackwater from domestic, commercial, …

Het Knowledge Mile Park (KMP), momenteel de drukste verkeersader van Amsterdam, wordt de komende jaren uitgebreid vergroend. Op diverse locaties langs de KMP werd steekproefsgewijs hittemetingen uitgevoerd om hittestress op te sporen, verkoelingscapaciteit van het aanwezige groen te meten en het thermisch …

Due to climate change, rising temperatures lead to more extreme heat stress in urban areas. Last summer, there were poignant images of people looking for shade in cities. Trees are effective measures to provide shade and decrease the perceived temperature. However, trees cannot grow in healthy conditions …

Objective. After laryngectomy, the breathing resistance of heat and moisture exchangers may limit exercise capacity. Breathing gas analysis during cardiopulmonary exercise testing is not possible using regular masks. This study tested the feasibility of cardiopulmonary exercise testing with a heat and …

Purpose: The aim of this study was to asses if a combination of events related to injuries (surrogate measures) in Ski Cross (SX) is more likely to lead to crashing than one surrogate measure and how it differs between male and female athletes. Method: The data collected by using video analysis on the …

Klimaatadaptatie bevindt zich in een fase van implementatie en versnelling, wat terug te zien is in de snelle verspreiding van maatregelen voor stedelijk water- en hittebeheer in steden over de hele wereld. Met name op natuur gebaseerde oplossingen ('nature-based solutions' of NBS) zijn recentelijk in …

Abstract. Although the U-value of glazing has improved significantly in the last decades, the thermal transmittance of windows remains relatively high compared to opaque elements of the thermal shell. Consequently, glazing has a relatively low interior surface temperature in the heating season, which …

Blue-green roofs have been utilized and studied for their enhanced water storage capacity compared to conventional roofs or extensive green roofs. Nonetheless, research about the thermal effect of blue-green roofs is lacking. The goal of this research is to study the thermal effect of blue-green roofs …
