Manz Polishing Sand Filter

Wednesday, November 16 – 8:30 to 9:15 am

Removal of Iron and Manganese using Oasis Filter MPSF Technology

Manz Slow Sand Filter (MSSF) and the Manz Polishing Sand Filter (MPSF) are important adaptations of traditional slow sand filtration that allow:
1. Demand Operation
2. Cleaning using backwash

The MSSF preserves the ‘schmutzdeke’ or ‘biolayer’ in order to enable removal of pathogens. The MPSF does not require the development of a schmutzdeke or biolayer to function. The MPSF exploits the ability of traditional slow sand filters (SSF) to remove very small particulate material. The ability to be cleaned using backwash greatly expands the use of SSF for ‘polishing’ purposes – iron, manganese and arsenic removal in particular. Both the MSSF and MPSF technologies are unique and patented.

On-Site Chlorine Generation – Risk Management that Pays for Itself

Wednesday, November 16 – 8:30 to 9:15 am

On-site generation of sodium hypochlorite and/or chlorine gas is fast becoming a preferred method of chlorine supply within Water treatment facilities.

On-site generation of chlorine not only reduces the hazard potential of transporting and storing volumes of pressurized chlorine gas, it can also provide overall cost efficiencies to the end users.

Over the past few years, the technologies and equipment required for these systems, have also demonstrated their overall capabilities and reliability.

Go Green

Wednesday, November 16 – 8:30 to 9:15 am

The Go Green Fund is a financial commitment from the Government of Saskatchewan to assist Saskatchewan’s people, communities, non-government organizations and businesses address the province's most important environmental issues. The Go Green Fund supports practical, cost-effective solutions delivered through innovative environmental technologies, processes and improved public understanding. Larger scale initiatives that demonstrate significant environmental benefit and those that have the potential for adoption and/or replication elsewhere in Saskatchewan will be favoured. ‘Ordinary course-of-business’ activities are not eligible for funding.

Source Control Basics

Wednesday, November 16 – 9:45 to 10:40 am

This presentation will provide an overview of the history of Source Control as a wastewater utility management approach in Canada. The objectives of a source control program will be identified and several programs that are currently active in western Canadian cities will be briefly reviewed. Basic elements of the source control approach that can be implemented by smaller communities, as well as the resources that are available to assist communities with their programs, will be discussed.

Controlling Disinfection By-Products

Wednesday, November 16 – 9:45 to 10:40 am

Chlorine, chlorine dioxide, chloramines and ozone are commonly used in many municipal water treatment systems as disinfectants. The purpose of these disinfectants can also extend to use as oxidants for taste and odour control, iron and manganese removal, and coagulant aids. The disinfection by-products (DBP's) formed when these disinfectants are used include trihalomethanes, haloacetic acids, chlorate, chlorite, NDMA and bromate. The actual DBP's formed will depend on the type and dose of disinfectant used, and the presence of natural organic matter (NOM) in the water supply.

This presentation will provide an overview of the current regulatory framework which establishes the maximum acceptable DBP concentrations in municipal water supplies, and presents various treatment strategies and technologies that municipalities currently utilize to operate within the regulatory limits.

SCADA – A Snapshot of Municipal SCADA systems

Wednesday, November 3 – 9:45 to 10:40 am

SCADA is a tool that carries out a variety of responsibilities in the development, expansion, monitoring and controlling of water, wastewater, drainage and environmental municipal infrastructure.

Eleven municipalities in southwest British Columbia were interviewed regarding their SCADA system and the information gathered is summarized and presented. It includes current utilization, age of SCADA and related equipment, the pre-SCADA experience and future wish lists for their system.

Stakeholders Meeting

Wednesday, November 3 – 10:40 to 11:25 am

How the “Best Practices” will impact you the operator and your organization. Reciprocity within Canada - what is it? How could it affect you? More CEUs for certification, when does it take effect?
