1. 1. Wastewater Characterisation for Design and Modelling of Primary Settlers at Municipal Wastewater Treatment Plants

   University essay from Lunds universitet/Industriell elektroteknik och automation

   Author : Louise Westin; [2023]
   Keywords : Primary Settling Tank; Wastewater Treatment; Settleometer; Particle Settling Velocity Distribution; Modelling.; Technology and Engineering;

   Abstract : The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. READ MORE

3. 2. Washing efficiency in the pulp mill : An evaluation of the washing efficiency in SCA Munksund's pulp mill

   University essay from KTH/Fiber- och polymerteknologi

   Author : Malin Malmberg; [2023]
   Keywords : Chemical Pulp; Lignin; COD; Pulp Washer; Kraft Pulping; Pappersmassa; Lignin; COD; Massatvätt; Sulfatmassaprocessen;

   Abstract : Munksunds pappersbruk är ett integrerat massa- och pappersbruk som består av två fiberlinjer, en barr- och en lövlinje där båda kokarna är kontinuerliga med efterföljande tvättsteg. En kartering av COD (eng. Chemical Oxygen Demand) och natrium utfördes för båda linjerna för att utvärdera tvätteffektiviteten. READ MORE

4. 3. Effect of substrate types on fermentation of mixed cultures to produce volatile fatty acids

   University essay from KTH/Industriell bioteknologi

   Author : Jayant Sehgal; [2022]
   Keywords : Mixed culture fermentation; Volatile fatty acids; Chemical oxygen demand; pH; starch; oil; gelatin; substrates; VFA production; Blandkulturjäsning; Flyktiga fettsyror; Kemiskt syrebehov; pH; stärkelse; olja; gelatin; substrat; VFA-produktion;

   Abstract : Innovativa teknologier, produkter och processer krävs på grund av marknadens ökande behov av bioprodukter med låga koldioxidavtryck. Idén att producera flyktiga fettsyror via biologiska processer, främst genom anaerob fermentering med blandkulturer, har återupplivats på grund av den omfattande exploateringen av oljeresurser.

6. 5. Assessment of on-site wastewater treatment systems in unsewered communities in Jordan

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Hani Yahya Ali Shubail; [2020]
   Keywords : Constructed wetland; Decentralized wastewater treatment; Jordan; On-site wastewater treatment system;

   Abstract : Centralized wastewater treatment systems need substantial funds besides high-cost operation and maintenance programs, which could be considered unsuitable for low-income developing countries. As a solution, it becomes the trend towards on-site wastewater treatment systems (OWTs) due to its cost-effectiveness and flexibility of implementation and management. READ MORE
