HV-TURBO aeration compressors

ChartWater includes Howden equipment in its aeration portfolio. The HV-TURBO brochure separately illustrates a large unit at 40000–80000 Nm³/h and 0.4–1.5 bar differential pressure. These figures describe that example rather than the entire compressor range.

ChartWater scope and equipment identity

ChartWater brings together water treatment solutions associated with AdEdge, BlueInGreen, Chart cryogenic equipment, and Howden aeration equipment. The July 31, 2025 legal merger announcement concerns AdEdge and BlueInGreen.

A technology name, an equipment manufacturer, and the legal company name therefore serve different purposes when identifying an installed system.

Separate gas dissolution, packaged water treatment, filtration media, carbon dioxide storage, and aeration compressors in the enquiry. A brochure for one item does not establish the specification of another.

Identify both the existing treatment process and the requested scope, whether this is one replacement component or equipment for a new process section. Include the nameplate rather than relying only on the facility name.

Information needed for a replacement part

Provide a clear equipment nameplate, an overall photograph, and the markings of the component being replaced. If a parts list is available, identify the relevant line and its position on the assembly drawing.

Preserve model suffixes, serial numbers, and revision identifiers because similar looking components can have different connections or electrical arrangements.

State the quantity, reason for replacement, and the requested assembly boundary. A valve enquiry benefits from connection size, service medium, and documented operating conditions. An instrument requires its measurement range, supply, and signal details.

These are observations about the installed item, not universal specifications for the brand. The responsible site specialist should assess installation suitability against the equipment documentation.

Defining an SDOX or CDOX project

For a new process, provide water flow, water chemistry, temperature, treatment objectives, and available gas supply. Distinguish oxygen delivery from carbon dioxide pH control because they require different process information.

For an existing system, add the installed module designation, its connection arrangement, and the specific items requiring replacement or investigation.

Record measured conditions together with the operating state in which they were observed. A dissolved oxygen value or a pH reading alone does not establish the required treatment duty. For an upgrade, describe the desired change separately from the current result.

Equipment selection supports the specification process; it does not replace the project design or the safety assessment for work on an operating plant.

Preparing a PFAS treatment specification

List the compounds identified by laboratory analysis and retain their measurement units. Include other water quality parameters, flow, operating schedule, and site space. ChartWater documents GAC, ion exchange, FLUORO-SORB, and FR-RO as different treatment approaches.

A project enquiry should make clear whether it concerns a new process or replacement items in an installed treatment train.

For existing adsorption vessels, identify the media, vessel dimensions, number of units, and available operating history. For a membrane section, supply the installed module designations and stage arrangement. State required outlet targets separately from current measured performance.

This gives each proposal a common basis for evaluation and prevents a result from another installation being mistaken for a prediction for the source water at your site.

Establishing the WaterPOD package boundary

WaterPOD identifies a containerized treatment arrangement rather than a single fixed list of internal equipment. The brochure describes project configurations and enclosure options.

Before selecting a package, define the contaminants, treatment flow, climate, access route, and connection points for water and electrical services. Clarify which site works are included in the project.

For a module already in operation, provide the internal equipment list and photographs of the relevant pumps, valves, control cabinets, and piping. Container length alone cannot identify a replacement pump or controller.

For a new system, document the interface between the delivered module and the site installation. Agree the treatment scope and enclosure configuration explicitly so that transport, utility planning, and receiving inspections can follow the same equipment schedule.

Reading the VSi-CO2 capacity table

The Chart table distinguishes model designation, gross and net capacity, Ton and Tonne units, maximum allowable working pressure, and physical dimensions. Use the net metric carbon dioxide capacity where the project requires usable mass.

The number in a model designation is not a direct statement of usable capacity in metric tonnes.

For replacement items on an installed vessel, provide the vessel documentation and the component tag on its diagram. The brochure lists pressure and level instruments, valves, and regulators, but the actual assembly must be checked against its configuration.

Do not transfer carbon dioxide service parameters to oxygen equipment or another gas. Material compatibility, safety settings, and return to service depend on the specific system documentation and the responsible site engineering assessment.

Specifying adsorption media or biological treatment

For Bayoxide E33 or another treatment material, identify the existing product, quantity in the latest schedule, and filter vessel details. Add raw and treated water analysis, flow, and observed pressure difference.

This helps distinguish a request for the same material from a proposal to change the treatment process. Record the operating conditions associated with the measurements.

Plan the replacement quantity, removal arrangements, and handling of used material with the responsible site personnel. A product name does not establish a universal media replacement interval.

For biottta, also provide the model, stage arrangement, operating schedule, and a list of required components. Biological treatment and adsorption media replacement represent different process tasks and need separate technical information even if they appear in one procurement enquiry.

Selecting aeration compressor equipment

Provide the HV-TURBO nameplate, compressor designation, and drive details. For a new machine, state the required flow together with reference conditions, differential pressure, control requirement, and inlet environment.

Normal and actual cubic metres cannot be compared without a common reference basis. Supply the plant duty or operating profile rather than a nominal flow value alone.

For a replacement component, include its position on the assembly drawing and the installed markings. The brochure describes different control arrangements: IGV, VDV, and Dual Point Control depend on configuration.

The large unit example at 40000–80000 Nm³/h is not the specification of every compressor. The operating point, drive, and connections must be matched to the actual machine rather than inferred from a similar casing or a portfolio photograph.

Enquiry, quotation, and delivery planning

Use the page form to send the model, quantity, photographs, and a technical specification. A new equipment enquiry should define the required process outcome; a parts enquiry should identify the component and installed machine.

If several systems are involved, separate the requested items into a clear equipment schedule with quantities and units. Keep drawing references consistent across attachments.

The quotation preparation period depends on the completeness of the input and the complexity of the package; the expected response timing is agreed after the enquiry is reviewed. Compare item designations, quantities, and package boundaries against the submitted schedule.

For equipment delivery planning, identify the destination, receiving constraints, utility interfaces, and the party responsible for each site connection. Keep acceptance criteria attached to the selected configuration.

Receiving equipment and keeping its identity

Before delivery, establish who will receive the equipment and which agreed schedule will be used to check the shipment. A large module may require an access route, unloading arrangements, and a prepared placement area.

Individual parts benefit from packaging labels that link each item to the correct equipment position.

On receipt, compare the markings and quantities with the agreed schedule and record packaging condition and visible damage. Use the item documentation for storage and installation preparation. Dry media, electronic instruments, and gas service components require different handling procedures.

Record the installation date and the replacement designation in the equipment history so that a later enquiry can identify what is actually fitted.
