The other unique fact being that the sterile by-product ash is disposed from site and sold as “Agri Ash” an agricultural soil conditioner. Since its inception in 1978 the way this multi hearth furnace is operated has evolved to account for increased stringencies in the environmental emissions license, greater solids loads due to population increase and a secondary augmentation upgrade, as well as a result of the maintenance issues associated with running large pieces of plant continuously. Given its inherently complicated and chaotic nature, operating this dynamic process is a task that requires considerable training and operational experience as does understanding its interrelationship with the broader treatment process used at the LMWQCC.

The thesis may not be reproduced elsewhere without the permission of the Author. The effect of silver ion-implantation of stainless steel on bacterial adhesion and biofilm formation Mehak Dhillon 2012 The effect of silver ion-implantation of stainless steel on bacterial adhesion and biofilm formation A thesis presented in partial fulfilment of the requirements for a Master of Science in Microbiology at Massey University, Palmerston North, New Zealand. Mehak Dhillon 2012 i ABSTRACT Biofilms comprise an assembly of microbial communities attached to a surface and enclosed in a polysaccharide matrix. Biofilms are a problem in dairy manufacturing plants where they cause biofouling of the stainless steel surface, resulting in product contamination and the need to shorten manufacturing runs for frequent cleaning. The equipment has to be thoroughly cleaned at regular intervals to remove biofilms. Clean- In-Place (CIP) procedures used in dairy manufacturing plants are not effective enough to remove all the biofilm cells as the extracellular polysaccharide (EPS), an integral part of a biofilm, reduces the penetration of cleaning agents. One possible alternative method to control biofilm growth involves surface modification of the stainless steel by implanting silver ions to prevent the attachment of viable bacteria that would otherwise form biofilms. Stainless steel coupons, implanted with 1 × 1016 silver ions per cm2, and control stainless steel coupons were tested for the attachment of Streptococcus thermophilus and Pseudomonas fluorescens in various media for up to 30 minutes.

  • Cleaning of Pressure Pipes with Novel Technology – the Importance of Long-Term Bond Randall J. Cooper¹ and Mark A. Knight²
    Cleaning of Pressure Pipes with Novel Technology – The Importance of Long-Term Bond Randall J. Cooper¹ and Mark A. Knight² ¹Consulting Engineer, Envirologics Engineering Inc., 5-193 Manitoba Street, Bracebridge, ON, Canada P1L 1S3; email: [email protected] ²Associate Professor, Department of Civil and Environmental Engineering, University of Waterloo, 200 University of Waterloo, Waterloo, ON, Canada N2L 3G1; email: [email protected] Abstract This paper presents an innovative patent-pending, environmentally-friendly, “waterless” method of pressure pipe cleaning using airborne abrasives. This innovative cleaning method not only removes corrosion products quickly, it leaves the pipe interior in a “ready state” for the trenchless application of spray-in-place (SIPP), cured-in-place (CIPP) and/or cement linings. SIPP liners are often referred to semi-structural while CIPP liners are referred to as structural. Unlike other methods that are intended only for cleaning pipe, this new method provides enhanced pipe surface preparation and dries the pipe for superior liner bond. This paper highlights the importance of pipe cleaning and preparation in advance of installing semi- structural or structural pressure-pipe liners. It also provides details and limitations of this novel patent-pending technology. Early and promising results from a recent trenchless water main rehabilitation project, in Cambridge Ontario, showed that coal-tar coatings on ductile/cast iron pipe can be removed effectively and efficiently and the pipe can be prepared for bonding/adhesion with a SIPP liner. Introduction According to Folkman (2012), the percentage of cast and ductile iron in water distribution networks can range from 50 percent in the Northern central USA to 90 percent in the south.

  • Guidance on Monitoring the Biological Stability of Drinking Water in Distribution Systems
    Guidance on Monitoring the Biological Stability of Drinking Water in Distribution Systems Guidance Document for Public Consultation Consultation period ends October 16, 2020 Guidance on Monitoring the Biological Stability of Drinking Water in 2020 Distribution Systems – For Public Consultation Background on guidance documents Health Canada works with the provinces, territories and federal agencies to establish the Guidelines for Canadian Drinking Water Quality. Over the years, new methodologies and approaches have led Health Canada, in collaboration with the Federal-Provincial-Territorial Committee on Drinking Water, to develop a new type of document, guidance documents, to provide advice and guidance on issues related to drinking water quality for parameters that do not require a formal Guideline for Canadian Drinking Water Quality. Guidance documents are developed to provide operational or management guidance related to specific drinking water–related issues (e.g., boil water advisories), to make health risk assessment information available when a guideline is not deemed necessary. Guidelines are established under the Guidelines for Canadian Drinking Water Quality specifically for contaminants that meet all of the following criteria: 1. exposure to the contaminant could lead to adverse health effects; 2. the contaminant is frequently detected or could be expected to be found in a large number of drinking water supplies throughout Canada; and 3. the contaminant is detected, or could be expected to be detected, at a level that is of possible health significance. If a contaminant of interest does not meet all these criteria, Health Canada, in collaboration with the Federal-Provincial Territorial Committee on Drinking Water, may choose not to develop a Guideline Technical Document.
