Hargrave & Burdick, Environmental Inc.

Hargrave & Burdick, Environmental Inc.

Hargrave & Burdick, Environmental Inc. provides planning, scientific and engineering services for a broad range of environmental issues in the water and wastewater field. The company and staff have a client-centred approach to business and have extensive experience with all levels of government. The staff are experienced in water facilities and systems servicing communities with a population ranging in size from less than a hundred to over one million. The company's staff has extensive experience in consulting, management of utility systems, and training. Equally important, they are all experienced in project and team management. This allows them the opportunity to carefully select exactly the correct team for each project they undertake.
Their training experience includes teaching water treatment plant design at the university level, training plant operators during treatment plant commissioning, and preparing Online Interactive Documents for operations and maintenance instruction. Hargrave & Burdick is currently working in both the United States and Canada.

Conduct A Composite Correction Program
The Composite Correction Program is a procedure developed by the USEPA to address performance limiting factors at wastewater treatment plants and to obtain improved performance. This formal procedure is now being applied to water treatment plants in Canada. The Composite Correction Program consists of two components, the Comprehensive Performance Evaluation (CPE) phase and the Composite Correction Program (CCP) phase. During the CPE phase a thorough review and analysis are made of the treatment plant's major unit process capabilities at design flow, and existing administrative, operation, and maintenance practices. Factors are identified and prioritized by the degree they may be affecting the treatment plant performance, and whether significant improvements can be made without capital expenditures. During the CCP phase factors identified during the CPE are systematically eliminated to improve performance. Because the program also includes the evaluation of the administrative, operation and maintenance areas, it can identify and recommend many other improvements. These can include education programs for administrative personnel, water and sewer rate studies, operator staffing evaluation, operator training, better laboratory quality control, and implementation of maintenance management systems. The Composite Correction Program is a low cost technique for optimizing the performance of water and wastewater treatment plants. It can lead to improved drinking water and wastewater effluent quality, more effective use of existing facilities, improved plant maintenance, and postponement of plant expansions.

Control Disinfection By-product Formation, Or Remove Dbps After They Are Formed
Disinfection By-products are formed when natural organic material in water is oxidized with chlorine, ozone, or other oxidizing agents. Chloroform and other trihalomethanes, formed during drinking water chlorination, are the most commonly occurring organic chemicals in drinking water. Ozonation of surface water containing natural organics for either disinfection or colour removal also forms by-products. These by-products can include aldehydes, aliphatic and aromatic carbonylic acids. Insufficient information is available to show whether DBPs of ozone have a potential health significance. Water treatment process modifications to reduce DBPs must not compromise disinfection of the water or enhance conditions in the water distribution system to cause microbiological regrowth. Three methods can be used to reduce DBPs in the finished water. Remove the natural organic material in the water (DBP precursors) prior to oxidizing processes such as chlorination and ozone Defer disinfection until after filtration so that conventional treatment will have reduced the DBP precursors Remove the DBPs formed. Sometimes selecting a different water source with lower organic material concentrations is the most cost-effective alternative. Prior to chlorination or ozone organic material can be removed using oxidizing agents other than chlorine, membrane technology, carbon adsorption, enhanced coagulation or biological treatment. The most effective method depends on the chemistry of the water and the nature of the organic material. Many water treatment plants add chlorine at the head end of the treatment plant to provide sufficient contact time in the treatment plant for disinfection. As a result chlorine is added when the natural organic material concentration is at its highest. By converting a treated water reservoir to a chlorine contact tank or constructing a chlorine contact tank downstream from coagulation and filtration processes, the chlorine addition can be deferred until much of the natural organic material is removed. Once Disinfection By-products are formed, they can be removed by air stripping, carbon adsorption, membrane technology, or biological treatment. Again the most effective method is site specific as a particular DBP may be more easily removed by a certain process. Feasibility studies including bench scale and possibly pilot testing can determine which of the three approaches should be taken to solve the high DBP concentration, and what group of processes will most cost-effectively meet the water quality goal.

Conversion Of Manuals To Online Interactive Documentation
If you have an Operation & Maintenance manual (O&M manual) that is voluminous, not used frequently, difficult to understand, or has specific information that is hard to find when you need it. The document is a candidate for conversion to Online Interactive Documentation. What is Online Interactive Documentation, OID? OID is documentation converted to an electronic format with hypertext, graphics, photographs, and search tools thus increasing access to the information, and making it easier to understand, and remember. Information is not useful if you have a difficult time finding it or are unable to understand it once you do find it. If properly written O&M manuals can provide training to Operators and systemize their work into Standard Operating Procedures. When used, the manuals can encourage better plant performance, and preservation of the municipality's asset. Effective O&M manuals must be understandable, and needed information must be easy to find. OID can meet these needs. O&M manuals converted to an OID can include. Search engines to find needed information quickly Ability to print SOPs so they can be taken to the field for use Technical reference information that supports all processes and equipment Graphics with exploded views of equipment and part numbers Photographs of equipment that are usually difficult to see (i.e. submerged, or buried) Process simulation Detailed index of equipment manufacturers' maintenance information Pop-ups with phonetic pronunciation, and definitions of terms, units, and abbreviations Browse buttons to allow the user to read related topics. A useful O&M OID is built and presented in layers. Critical information is presented in the top layer; less critical information is placed in deeper layers so that the Operator will have immediate access to critical information and can click to deeper layers if he or she requires it. Graphics and photographs can be placed, depending on their use, in the top layer or in a deeper layer. Experts in the subject field should prepare the reformatting and layering of information so that topics are properly broken down and linked, and key word indexes are meaningful. If done properly the reformatted text will provide the maximum benefit of online documentation. The benefits of OID as a training tool, and an easy-to-use reference provide a cost-effective means of solving the problem of not using O&M manuals for Operator training and plant maintenance.
