Design And Analysis of Pressure Disc Type Filter
Abstract:
Presently used Filters for Beverages making industries are very bulky in shape and gives low outlet discharge. Hence they are less efficient .Therefore there is a need to design compact, automated unit that produces completely clear liquor and which have large outlet discharge. This concept highlights the design of new filter which fulfill the requirements of beverages making industries for filtration. For making filtration more feasible, unit is to be design in which multiple disc comprising of blades is to be mounted on a shaft for filtration. Multiple discs will get patterned throughout the shaft and number of disc decides the capacity of filter. The special arrangement of Two cake discharge blades (scrapper remover) suspended from a frame mounted on the tank and serve to deflect and guide the cake to the discharge tube. On large diameter filters, the blades are of the swing type that float to maintain the cake to disc clearance and so allow for the wobble of the turning discs.

An Engineers Guide to Shaft Alignment, Vibration Analysis, Dynamic Balancing & Wear Debris Analysis
Introduction
The purpose of producing this handbook is to provide basic information and guidelines for the implementation of good shaft alignment, vibration analysis and dynamic balancing practice for standard rotating machines systems.
Laser alignment, dynamic balancing and condition monitoring are essential components of a viable maintenance strategy for rotating machines. In isolation each strategy helps to reduce unexpected machine failure but taken together they form the hub of a proactive maintenance strategy that will not only identify incipient problems but will extend machine operating life considerably.
In each section of this handbook we have used one or two examples of the available methods for measuring the required parameters. We do not suggest that the methods illustrated are the only ones available. For anyone wishing to pursue further the subjects covered here a bibliography of some of the available literature is to be found at the end of this handbook.

Design of Sanitary Sewers
Introduction:
Sewer systems are essential for the public health and welfare in all areas of concentrated population and development. Every community produces water‐borne wastes of domestic, commercial, and industrial origin. Sewers perform the virtually needed functions of collecting these wastes and conveying them to points of discharge or disposal.

Design of Reverse Osmosis Process For The Purification Of River Water In The Southern Belt Of Bangladesh
Introduction
Abundance and quality water supply is essential for all living species. Sustainable agriculture and industrial production need steady supply of freshwater. In many parts of the today’s world, desalination plays a vital role for sustaining human habitation besides the existing conventional water treatment technologies. Membrane based RO process has become a popular method to supply the fresh water from seawater and brackish water in different regions. RO (Figure 1) is a pressure driven process which under pressure reverses the flow direction of the solvent (in the opposite direction of osmosis process). Substantial efforts have been made by researchers on freshwater production (Sassi, 2012) and wastewater treatment (Stoller et al., 2016) using the RO. Rapid growth of membrane desalination processes enhanced the removal of ionic contaminants (Sassi and Mujtaba, 2013), pharmaceutical active compounds (Gur-Reznik et al., 2011) and other types of effluents from chemical, petrochemical, electrochemical, food, paper and tanning industries. Demineralised water can be supplied to several industries by treating the saline water using the RO process. However, there are limited studies on the production of demineralised water. Demineralised water is completely free (or almost) of dissolved minerals (Kremser et al. 2006) which has total dissolved solids (TDS) as low as 1 mg/l. Kremser et al. (2006) described operating experience on demineralized water plant.
In this work, RO based desalination process is considered using three stages described by (Sassi, 2012) as shown in Figure 1. The plant nominal operating and design parameters (of commercial Film Tec spiral wound RO membrane elements) are taken from Abbas (2005). Firstly, the model prediction is validated against those reported by Sassi and Mujtaba (2010). Secondly, an optimization problem incorporating a process model is formulated to optimize the design and operating parameters in order to minimize specific energy consumption and the results are compared with Sassi (2012). Since those models (Sassi, 2012) are validated for freshwater production, the model parameters such as (water and salt permeability coefficients) needs to be updated for demineralised water. A structure of the RO network is developed based on RO network (two-stage seawater pass and two-stage brackish water pass). Different parameters are updated for the model from the literature.
