PC GUIDELINES
PC Guide 1: Pollution Control
Overview: The status of man’s health represents the result of complex interactions between his internal biological system and the total external environmental system. Although this volume is concerned primarily with the external environmental system, it is important to bear in mind the relationship between man and his environment.
PC Guide 2: Water Treatment
Overview: There are 3 main sources of water for domestic and industrial purposes. These are surface waters, groundwater and the direct collection of rainwater.
PC Guide 3: Wastewater Treatment
Overview: The historical sequence of engineering constructions for the biological treatment of wastewater proceeded from sewage farms through intermittent sand filters and contact beds to biological filters or trickling filters to activated sludge. It is understandable that treatment began as a farming practice. The wastewater that poured onto.
PC Guide 4: Phosphorus removal from wastewater
Overview:In the Water and Wastewater industry, we will always express the Phosphorus content as P. This does not matter if the phosphorus is present as a phosphate ion or combined with organic materials such as phospholipids, polyphosphates etc. In other sciences, such as geology and agriculture, the phosphorus content is often expressed as P2O5. This is a very old fashioned way of expressing the phosphorus content.
PC Guide 5: Electricity
Overview: Electricity may be thought of as the presence and flow of electric charge. An electric charge is a property of matter. In the same way, mass, volume or density is a property of matter – this means that we can measure the mass of something and the volume that it occupies. One can also measure how much charge it has.
PC Guide 6: Pump, Blowers and their operations
Overview: Pumps are used to move liquids (including sludges) from one point to another. They require an energy input in order to do the work of moving this liquid or sludge.
PC Guide 7: Mechanical transmission of power
Overview: This Process Controller’s Guide covers the equipment that fits in between the electric motor and the pumps or blowers and other items of equipment associated with the mechanical transmission of this power.
PC Guide 8: Flow Measurement
Overview: The job of the Process Controller as the name suggests is to control the water and wastewater treatment processes to achieve the desired outcome. To be able to control the process optimally, the Process Controller needs to know many variables – the one that we will deal with in this guide, is that of flow of both water and air including chemical solutions such as coagulant dosing.
PC Guide 9: Iron & Sulphur compounds in water & wastewater environment
Overview: Iron is a chemical element with the symbol Fe and atomic number 12. The most common form (91.8%) has an atomic mass of 56. The weighted mean atomic mass is 55.845. By mass, it is the most common element on earth and the 4th most common in the earth’s crust after Oxygen, Silicon and Aluminium.
Sulphur (also known as Sulfur) is a chemical element with the symbol S and atomic number 16. The most common form (95%) has an atomic mass of 32. It falls in the same group as Oxygen in the periodic table. It therefore shares some similar properties with oxygen but being about 60% larger than an oxygen atom, also shows several differences from oxygen.
PC Guide 10: Management and Supervision
Overview: All organisations, in both the private and the public sector, need a properly designed structure. There will be a top decision making body that in involved in the policy and decision making that guides and runs the organisation. This decision making body will receive reports etc. from the senior management, take a resolution on the action to be taken and then refer this back to the management for implementation.
PC Guide 11: The Microbiology of Wastewater Treatment
Overview: In a chemical process, there is a change in the composition or chemical make up for the material or materials.
