To properly operate a waterworks or wastewater treatment plant and to pass the examination for a waterworks/wastewater operator's license, it is necessary to know how to perform certain calculations. All operators, at all levels of licensure, need a basic understanding of arithmetic and problem-solving techniques to solve the problems they typically encounter in the workplace. Hailed on its first publication as a masterly account written in an engaging, highly readable, user-friendly style, the Mathematics Manual for Water and Wastewater Treatment Plant Operators, Second Edition has been expanded and divided into three specialized texts that contain hundreds of worked examples presented in a step-by-step format. They are ideal for all levels of water treatment operators in training and practitioners studying for advanced licensure. In addition, they provide a handy desk reference and handheld guide for daily use in making operational math computations. Basic Mathematics for Water and Wastewater Operators introduces and reviews fundamental concepts critical to qualified operators. It builds a strong foundation based on theoretical math concepts, which it then applies to solving practical problems for both water and wastewater operations. Water Treatment Operations: Math Concepts and Calculations covers computations used in water treatment, and Wastewater Treatment Operations: Math Concepts and Calculations covers computations commonly used in wastewater treatment plant operations. The volumes present math operations that progressively advance to higher, more practical applications, including math operations that operators at the highest level of licensure would be expected to know and perform. To ensure correlation to modern practice and design, the volumes provide illustrative examples for commonly used waterworks and wastewater treatment operations covering unit process operations found in today's treatment facilities. Readers working through the books systematically will acquire a definitive understanding of and skill in performing the applied water/wastewater calculations that are essential for a successful career in the water industry.

Prediction of microbial transport distances are usually based on the sticking efficiency, a parameter in the classical colloid filtration theory. This parameter represents the interaction between colloid and collector surfaces resulting in deposition. According to the theory, the sticking efficiency is invariable when physico-chemical characteristics of aquifer media are homogeneous. However, many research results have indicated variations within bacterial strains. In this research, the transport of Escherichia Coli in saturated quartz columns were conducted in the laboratory. The objectives were to characterise the distribution of sticking efficiency, measure low sticking efficiency values of cells, and to develop a methodology to measure minimum values of sticking efficiencies within bacterial sub-populations. Also, the work assesses the contribution of phenotypic and genotypic characteristics of Escherichia coli on their attachment to quartz grains.

The treadle irrigation pump is able to lift up to 7000 litres of water per hour using the power of the human body, and can be locally made at low cost in small-scale metalworking shops. Its acceptance in Bangladesh, where it was first developed in 1984, is extraordinary, with over 500,000 pumps estimated now to be in use.;The current design offered in this manual has evolved from the Bangladesh original into a fully portable pump with both lift and pressure capacity and is especially appropriate to situations where soils are permeable, and water cannot easily be distributed through channels. The manual is intended to be read primarily by organizations engaged in economic development activities which have a particular expertise in technology transfer; it is not intended just as a step-by-step guide for the manufacturer (although it can be used in this way).

Water, sanitary and waste services represent a substantial proportion of the cost of construction, averaging 10% of the capital costs of building and with continuing costs in operation and maintenance. Nevertheless, they are often regarded as a 'Cinderella' within the building process.
