    Sammanfattning : McNeil AB är en producent av rökavväjningsprodukter Nicorette® belägen i Helsingborg, Sverige. Tuggummi och tabletterna är produkter med högst produktionsvolym och drageringsprocessen av dessa produkter är den största på siten. Produktionen förväntas att öka i framtiden och med det även utsläpp av processvatten. LÄS MER

  3. 2. Optimizing Sample Dissolution Methods of Low Water Soluble Intermediate Organic Compounds to Support Environmental Risk Assessment during Active Pharmaceutical Ingredient Manufacturing.

    Kandidat-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Warda Mohammed; [2021]
    Nyckelord :Active pharmaceutical ingredient; API; total organic content; TOC; chemical oxygen demand COD; biological oxygen demand; BOD; Microtox; octanol-water partition coefficient; Kow; solubility.;

    Sammanfattning : This project focus on investigating the dissolution of low water-soluble intermediate organic compounds called active pharmaceutical ingredients (API) and organic substances that are manufactured by a pharmaceutical company, Cambrex Karlskoga in Sweden. Several dissolution methods were used and evaluated using methods including total organic carbon (TOC), chemical oxygen demand (COD), biochemical oxygen demand (BOD) and Microtox toxicity test.

  4. 3. Assessment of on-site wastewater treatment systems in unsewered communities in Jordan

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

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

    Sammanfattning : 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. LÄS MER

  5. 4. Utredning av processavloppsvatten från Thermo Fisher Scientific : Föroreningsinnehåll samt utvärdering av driftförhållanden för bäst reningseffekt

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Hanna Eriksson; [2019]
    Nyckelord :MBBR; step loadning; serial operation; process wastewater; reduction capacity; BOD7; phosphorus; nitrogen; acetone; MBBR; stegbeskickning; seriell drift; reningseffekt; processavloppsvatten; BOD7; fosfor; kväve; aceton;

    Sammanfattning : Thermo Fisher Scientific (TFS), ImmunoDiagnostic (ID), Uppsala, produces instruments for allergy and autoimmunity tests. As TFS ID applied for allowance to increase the production level, it was given on the condition that the wastewater would be biologically pre-treated on the site, and a Moving Bed Biofilm Reactor (MBBR) was therefore built.

  7. 5. Physico-chemical evaluation of the water quality in Rocha River: A qualitative and comparative analysis including aspects of social and environmental factors

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi

    Författare :Stina Jacobson; Ida Sekizovic; [2019]
    Nyckelord :Cochabamba; Rocha River; water quality analysis; water pollution; wastewater; regulations; ICO-index; Hec-RAS; minor field study; Technology and Engineering; Earth and Environmental Sciences;

    Sammanfattning : In this study, a physico-chemical analysis of the Rocha River was performed during the beginning of the rainy season 2018 in order to examine the current state of the water quality in the river at six different locations. The river, located in the Cochabamba department, Bolivia, was examined from upstream in Sacaba to downstream in Sipe Sipe. LÄS MER
