  28. 28. Types of Wastes Solid wastes: domestic, commercial and industrial wastes especially common as co- disposal of wastes: plastics, Styrofoam containers, bottles, cans, papers, scrap iron, and other trash Liquid Wastes: Examples: domestic washings, chemicals, oils, waste water from ponds, manufacturing industries and other sources Emissions Examples: exhaust gases (CO2, CO, O2, NOx.

  90. 90. Residence time • Residence time (also known as removal time) is the average amount of time that a particle spends in a particular system. The residence time is a representation of how long it takes for the concentration to significantly change in the sediment. • Residence time is a widely used term that is mostly seen in science, technological and medical disciplines. Every discipline that uses residence time in some way adapts the definition in order to make it more specific to the application to which it is referring. The base definition for residence time also has a universal mathematical equation that can be added to and adapted for different disciplines..
  91. 91. Residence time • This is as follows: • Residence time begins from the moment that a particle of a particular substance enters the system and ends the moment that the same particle of that substance leaves the system. The system in question is arbitrary and can be defined as needed according to the application. If the size of the system is changed, the residence time of the system will be changed as well. The larger the system, the larger the residence time, assuming the inflow and outflow rates are held constant. The smaller the system, the shorter the residence time will be, again assuming steady- state conditions.
  92. 92. Residence time • Inflow and outflow will also have an effect on the residence time of a system. If the inflow and outflow are increased, the residence time of the system will be shorter. However, if the inflow and the outflow of a system are decreased, the residence time will be longer. This is assuming that the concentration of the substance in the system and the size of the system remain constant, and assuming steady-state [1] conditions
  93. 93. Relaxation time The Stokes number (Stk), named after George Gabriel Stokes, is a dimensionless number corresponding to the behavior of particles suspended in a fluid flow. Stokes number is defined as the ratio of the characteristic time of a particle (or droplet) to a characteristic time of the flow or of an obstacle, or
  94. 94. Relaxation time where is the relaxation time of the particle (the time constant in the exponential decay of the particle velocity due to drag), is the fluid velocity of the flow well away from the obstacle and is the characteristic dimension of the obstacle (typically its diameter). Particles with low Stokes number follow fluid streamlines (perfect advection) whereas for large Stokes number, the particle's inertia dominates so that the particle will continue along its initial trajectory.
  95. 95. Relaxation time In case of Stokes flow, which is when the particle (or droplet) Reynolds number is low enough that the particle drag coefficient is inversely proportional to the Reynolds number itself the characteristic time of the particle can be defined as where is the particle density, is the particle diameter and is the gas dynamic viscosity

  131. 131. ISO 14001 in briefe  ISO 14001 is among ISO's most well known standards ever.  It is implemented by some 887 770 organizations in 161 countries.  ISO 14001 helps organizations to implement environmental management
  132. 132. Environnemental management  ISO 14001 is for environmental management. This means what the organization does to:  minimize harmful effects on the environment caused by its activities,  to conform to applicable regulatory requirements, and to  achieve continual improvement of its environmental performance
  133. 133. Generic standards ISO 14001 is generic standard. Generic means that the same standard can be applied:  to any organization, large or small, whatever its product or service,  in any sector of activity, whether it is a business enterprise, a public administration, or a government department
  134. 134. Management systems Management system means what the organization does to manage its processes, or activities in order that its products or services meet the organization’s objectives, such as 1- satisfying the customer's quality requirements, 2- complying to regulations 3- meeting environmental objectives  To be really efficient and effective, the organization can manage its way of doing things by systemizing it.  Everyone is clear about who is responsible for doing what, when, how, why and where.
  135. 135. Processes, not products ISO 14001 concerns the way an organization goes about its work.  They are not product standards.  They are not service standards.  They are process standards.  They can be used by product manufacturers and service providers.  ISO 14001 gives the requirements for what the organization must do to manage processes affecting the impact of its activities on the environment
  136. 136. Certification and registration  Certification is known in some countries as registration.  It means that an independent, external body has audited an organization's management system and verified that it conforms to the requirements specified in the standard (ISO 14001).  ISO does not carry out certification and does not issue or approve certificates,
  137. 137. Accreditation  Accreditation is like certification of the certification body.  It means the formal approval by a specialized body - an accreditation body - that a certification body is competent to carry out ISO 14001:2004 certification in specified business sectors.  Certificates issued by accredited certification bodies - and known as accredited certificates - may be perceived on the market as having increased credibility.  ISO does not carry out or approve accreditations.
  138. 138. Certification is a business decision  Certification is a decision to be taken for business reasons:  if it is a contractual, regulatory, or market requirement,  If it meets customer preferences  it is part of a risk management programme, or  if it will motivate staff by setting a clear goal.
  139. 139. ISO does not certify  ISO does not carry out ISO 14001 certification.  ISO does not issue certificates.  ISO does not accredit, approve or control the certification bodies.  ISO develops standards and guides to encourage good practice in accreditation and certification.
  140. 140. The ISO 14000 family  ISO 14001 is the standard that gives the requirements for an environmental management system.  ISO 14001:2004 is the latest, improved version.  It is the only standard in the ISO 14000 family that can be used for certification.  The ISO 14000 family includes 21 other standards that can help an organization specific aspects such as auditing, environmental labelling, life cycle analysis…
  141. 141. Benefits of ISO 14001  International, expert consensus on state-of-the-art practices for quality and environmental management.  Common language for dealing with customers and suppliers  Increase efficiency and effectiveness.  Model for continual improvement.  Model for satisfying customers and other stakeholders.  Transfer of good practice to developing countries
  142. 142. Waste management
