Water Treatment Definitions

Aeration
The process of adding air to water. Air is added to water by passing air through water or passing water through air.

Diatomaceous earth filters
A filter technology using a thin layer of diatomaceous earth (a fine, siliceous material) that is deposited on a porous plate to serve as a filter. A good technology for smaller systems because of its relative simplicity of units and maintenance requirements. 

Direct filtration
A filtration process where the sedimentation stage of conventional filtration is omitted. Filtration is performed directly after the flocculation stage of treatment. A filter aid is usually added before filtration.

Dissolved air flotation
The process of solids removal whereby dissolved air is added to the clarifier from the bottom of the basin and the air raises suspended particles to the top of the water where the particles are removed by skimming.

Electrodialysis
The process where brackish water flows between alternating cationpermeable and anion-permeable membranes. A direct electronic current provides the motive force to cause ions to migrate through the membranes and either react to create a gas or remain in a separate solution as brine wastewater.

Horizontal-flow
A flow of water in a horizontal direction through a rectangular or round sedimentation and clarification basin, as opposed to the vertical or upward flow that is found in a solids-contact clarifier.

Injection mixers
The use of perforated tubes or nozzles to disperse the coagulant into the water being treated. Provides uniform distribution of the coagulant over the entire basin. Generally sensitive to flow changes and may require frequent adjustments to produce the proper amount of mixing.

In-line blender mixers
Used for coagulant mixing where coagulant is added through a diffuser in a pipe directly to water being treated. Provides rapid dispersion of the coagulant without significant heat loss. Energy consumption is less than a comparable mechanical mixer.

Mechanical dewatering
The use of mechanical devices such as centrifuges and rotational mechanisms to force the separation of solids (sludge) from liquids (water).

Mechanical mixers
These are paddles, turbines, and propellers frequently used in coagulation facilities. Mechanical mixers use electrical energy for mixing the coagulant with the water being treated.

pH adjustment
The alteration of the pH of the raw water or pretreated water by mechanical or chemical procedures to enhance the performance of the treatment process.

Reverse osmosis
The passage of water from a concentrated solution through a semipermeable membrane to fresh water with the application of pressure.

SCADA instrumentation
The Supervisory Control And Data Acquisition system is a computerbased system that monitors and controls remote water facility sites. A SCADA master control is typically located in a dedicated control centre or treatment facility control room. Remote sites are equipped with remote terminal units to gather information and issue instructions from the master station.

Solids composting
The mixing of sludge with decaying organic material for eventual use as fertilizer.

Stability or corrosion control
The removal of dissolved gases, treatment of the finished water to make it noncorrosive, and the building of protective coating inside the pipe.

Tube sedimentation
Tube settlers or high rate settlers are placed in rectangular or circular basins. Water enters the inclined settler tubes and is directed upward through the tubes. Each tube functions as a shallow settling basin. Particles collect on the inside surfaces of the tubes or settle to the bottom of the basin.

Up-flow solid-contact sedimentation
A unit that combines the coagulation, flocculation, and sedimentation processes into a single basin, which is either rectangular or circular in shape. Flow is an upward direction through a sludge blanket or slurry of flocculated, suspended solids.

Urban runoff
During dry periods, oil, grease, gasoline, and other residues accumulate on paved surfaces. During a storm, this material is washed into local receiving water from roadway storm drainage systems. Urban runoff also contains animal droppings from pets and fertilizers used for landscaping, the residues of which contribute to taste and odor complaints in drinking water.

Wastewater Treatment Definitions

The following definitions are provided for the interpretation of Table 3 of Schedule A.

Activated sludge
The wastewater treatment by aeration of suspended organisms followed by clarification, including extended aeration, Intermittent Cycle Extended Aeration System (ICEAS), and other similar processes. A sequencing batch reactor with the purpose of providing this form of treatment is rated under this category.

Biological or chemical and biological advanced waste treatment
The advanced treatment of wastewater for nutrient removal, including nitrification, denitrification, or phosphorous removal using biological or chemical processes or a combination. If the facility is designed to nitrify based solely on detention time in an extended aeration system, only the points for nitrification by designed extended aeration shall be given.

Chemical addition/Pretreatment
The addition of a chemical to wastewater at an application point for the purposes of adjusting pH or alkalinity, improving solids removal, dechlorinating, removing odors, providing nutrients, or otherwise enhancing treatment, excluding chlorination for the disinfection of effluent and the addition of enzymes or any process included in the tertiary treatment chemical and physical processes. The capability to add a chemical at different application points for the same purpose is rated as one application; the capability to add a chemical or chemicals to dual units is also rated as one application. The capability to add a chemical at different application points for different purposes is rated as a separate application.

Chemical or physical advanced treatment following secondary treatment
The use of chemical or physical advanced treatment processes following, or in conjunction with, a secondary treatment process. This includes processes such as carbon adsorption, air stripping, chemical coagulation, and precipitation.

Chemical or physical advanced treatment without secondary treatment
The use of chemical or physical advanced treatment processes without the use of a secondary treatment process. This includes processes such as carbon adsorption, air stripping, chemical coagulation, and precipitation.

Fixed-film reactor
Biofiltration by trickling filters or rotating biological contactors followed by secondary clarification.

Imhoff tanks (or similar)
Includes Imhoff tanks, septic tanks, spirogester, clarigester, or other single units for combined sedimentation and digestion.

Land application of biosolids by contractor
The land application or beneficial reuse of biosolids by a contractor outside of the control of the operator in direct responsible charge of the wastewater treatment facility.

Land treatment and disposal (surface or subsurface)
The ultimate treatment and disposal of the effluent onto the surface of the ground by rapid infiltration or rotary distributor or by spray irrigation. Subsurface treatment and disposal is accomplished by infiltration gallery, injection, or gravity or pressurized drain field.

Mechanical dewatering of solids
The removal of water from sludge by any of the following processes, including the addition of polymers in any of the following: vacuum filtration; frame; belt or plate filter presses; centrifuge; or dissolved air flotation.

Mechanical post-aeration
The introduction of air into the effluent by mechanical means such as diffused or mechanical aeration. Cascade aeration would not be assigned points.

Media filtration
The advanced treatment of wastewater for removal of solids by sand or other media or mixed media filtration.

Solids composting
The biological decomposition process producing carbon dioxide, water, and heat. Typical methods are windrow, forced air-static pile, and invessel.

Solids stabilization
The processes to oxidize or reduce the organic matter in sludge to a more stable form. These processes reduce pathogens or reduce the volatile organic chemicals and thereby reduce the potential for odor. These processes include lime (or similar) treatment and thermal conditioning. Other stabilization processes such as aerobic or anaerobic digestion and composting are listed individually.

(a) Three months of operating experience (Op Exp) or completion of an approved basic training course. It is recognized that the position of operator-in-training (OIT) is not a legally required position. It is included here to illustrate a method of encouraging new entrants in the field to enter into the certification program.

Note:
For Class I, the minimum operating experience requirement is one year, without substitutions. For Classes II, III and IV, substitutions may be made for required operating experience, but with the limitation that one half of all stated experience requirements (both operating and DRC) must be met by actual on-site operating experience in a facility or system. This experience should be obtained under the supervision of a certified operator or under an organized on-the-job training program.
