Available in PDF, EPUB and Kindle. Book excerpt: Water operators will find a wealth of hands-on information on the operation and maintenance of pretreatment, rapid-rate granular media filtration, slow-sand filtration, and diatomaceous-earth filtration systems in this book. This practical guide provides recommended procedures for operating, monitoring, and maintaining all types of filters used for conventional water treatment. These procedures are tested and time-proven by hundreds of water utilities and filtration experts to provide high filter efficiency, excellent water quality, long filter runs and minimum downtime. The book also gives advice on what not to do-and why-so you can avoid water quality problems, filter damage, and treatment problems in the future.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: California is tremendously dependent on water for a highly productive agricultural industry, growing commercial and industrial sectors, and the human population. In the next 15 years, the population is expected to grow dramatically, which will only put more pressure on an already tight water supply. Effective, low cost, simple, and reliable water treatment methods need be developed to alleviate this pressure. Two experiments were conducted to determine the efficacy of slow sand filters (SSFs) to remove plant pathogens from water to be reused for irrigation. The first experiment evaluated three increasing loading rates to determine if SSFs maintain efficacy. The second experiment was a field study in which SSFs that were initially exposed to Phytophthora capsici were then used to treat stream water known to contain numerous Phytophthora spp. A third experiment examined the effect of chilling and agitation on the recovery rate of P. capsici. Very low numbers of colony forming units were recovered below the sand surface during the fall trial of the slow sand filtration optimization experiment. Chilling and agitation of P. capsici propagules reduced the recovery of colony forming units. Slow sand filters are very effective at removing more than 99% of plant pathogen propagules from water and there was little difference in the removal rate between the slowest loading rate (0.15 m/hr) and the fastest (0.50 m/hr). In colder temperatures, the medium (0.25 m/hr) and fast loading rates caused the filters to foul. Slow sand filters established in the presence of P. capsici can remove other Phytophthora spp., however frequent fouling occurred due to turbidity of the creek water. Slow sand filtration is a simple, low cost, low maintenance, effective and reliable technology that can be used by nurseries to reduce water consumption.

This book was released on 2019-10-21 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Need of water purification was realized by man in early stages of civilization. So, Central and State Government are making efforts to provide adequate and safe drinking water to the people by constructing water treatment plants in the country. Filtration process under goes degradation at initial and last phase which affect the initial effluent quality of filtrate after back washing. The rapid sand filter is important unit of water treatment plant which removes the flocs and colloids through filtration After backwash filter when rapid sand filter brought back in to normal operation high initial turbidity of filtrate is observed. It is in the form of turbidity spike. To reduce this turbidity spike filter conditioning is essential. The present study is for rapid sand filter conditioning using coagulants as alum and polymer in different percentage during backwash of rapid sand filter. The optimal dosage as well as corresponding points of application during backwash will be determined based on laboratory scale studies which found to be improved in initial effluent quality of rapid sand filter.
