Wood ash has been widely used as an additive for excreta from dry compost toilets to sanitize it for reuse. However, there is dearth of quantitative information about its efficiency in sanitizing partially digested sludge from wet onsite sanitation systems. This paper presents findings of a series of two experimental studies to assess optimum wood ash dosages required to raise the pH of partial...

The environmental problems of paper board industry are not limited by the high water consumption, generate wastewaters and solid wastes. This paper presents the paper board industry effluent treatment plant components performance and physio-chemical characteristics of wastewater and sludge. In ETP operation most important factors is effluent characterization, flow rate, aeration tank dissolved ...

Abstract Accumulation of water treatment sludge is a major environment problem in the purification process. Recovery waste constituents or reuse cost-effective method handling this environmental dilemma. The present study investigates suitability production bricks and recovery aluminum from accumulated at Biyagama drinking plant (BDWTP) Sri Lanka. chemical parameters total organic carbon, pH, n...

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

In recent years, there have been many attempts to reuse molten slag. Molten slag is obtained through further treatment of incinerated ash produced in the disposal process of garbage or sewage sludge and is used in building materials, such as brick. To establish the safety of such slag, its physical properties and metal contents were investigated in this study. After examining the physical and c...

The agricultural spreading of treated sewage sludge is a valid strategy in terms circular economy for the management this nutrient-rich waste. Anaerobic digestion (AD) can be applied to stabilize and hygienize sludge, making it suitable reuse, while producing biogas utilized as an energy vector. However, presence contaminants, including petroleum hydrocarbons, could limit widespread utilization...

Moving bed biofilm reactor (MBBR) is a process in which attached growth is utilized for wastewater treatment. This process does not require sludge recycling or backwash. Activated sludge processes can be promoted to an MBBR by adding media to an aeration tank. Rapid sand filter is a physical method for the removal of total suspended solids (TSS) in advanced wastewater treatment. The purpose of ...

From the perspective of a circular economy that prioritizes resource reuse and recovery, sewage sludge could be source nutrients for agricultural soils or energy, depending on its characteristics. Lombardy is region with highest quantity production management in Italy. A methodology was developed to: extract analyze quantitative data (EWC 190805) (2017–2018); collect qualitative from publicly a...
