Water and wastewater system integrators are services that design, engineer and build wastewater systems for industries that range from small industrial plants to large municipal operations. These integrators have the ability to build a waste/wastewater system from the ground up, or to design it as part of a larger system alongside other processes or subsystems.
Water and wastewater system integrators should be selected based on types of systems they service, the type of services they provide, and the system components they are capable to service.
Water system integrators may have the capability to service one or more types of systems based on the type of water being processed.
- Potable water systems are those that involve potable (drinking) water.
- Process water systems are those that involve water from process streams.
- Wastewater systems are those that involve wastewater, including sewage and sludge.
Water system integrators can provide different types of services, ranging from system design to consulting.
- Complete system design involves design of all components required for a fluid processing application, including piping, tanks, and pumps.
- Component upgrades involve the upgrade or replacement of individual fluid processing components or sub-systems, such as pumping units, tanks, and heat exchangers.
- Design assistance involves helping clients with concepts, manufacturing costs or techniques, and material considerations. The supplier may also be able to assist in upgrading, re-designing, re-evaluating, or modernizing existing products to increase performance or reduce manufacturing costs.
- Repair involves the fixing or overhaul of damaged or defective parts.
- Inspection and optimization involves the quality analysis of components and processes. Suppliers will look for possible problems or inefficiencies in the system and provide feedback for process improvement.
- Preventative maintenance involves the upkeep of a facility through preemptive maintenance. Suppliers may provide plans or extended service contract agreements for fluid processing systems.
- Training and consulting involves advising and instructing clients about better system management and design practices.
Some integration suppliers may only service select components of fluid processing systems. These components include:
- Activated carbon or sand filters - Used to separate fluids from solid wastes using filtering media.
- Aeration ponds - Vessel which brings fluid in contact with water.
- Bar screens or raked screens - Screen which keeps large debris and solids from entering the processing system.
- Biofilters or membrane bioreactors - Vessels which incorporate membrane or microorganism filtration processes.
- Chemical or gas disinfectors - Components used to disinfect and purify water, removing undesirable bacteria or other microorganisms via disinfectant chemicals.
- Clarifiers or setting tanks - Used to remove solids through gravity settling or a mechanical screening process.
- Filtration beds - Layers of filter media which process fluid runs through to remove solids.
- Flotation tanks - Tanks which contain and store process fluids.
- Grinders or comminutors - Used to break up and refine solids in wastewater systems.
- Lagoons - Wastewater sewage storage sites used to dry sewage naturally over a period of time.
- Sequencing batch reactors - Fill-and-draw activated sludge systems for wastewater treatment.
- Skimmers - Remediation devices used to remove contaminants (such as oil) from the surface of water.
