Water Treatment & Purification Systems

01 / Storage

Water Storage Tanks

Water storage tanks provide a buffer between water-treatment stages and the filling process. Their position and working volume should match the available water supply, treatment flow and production schedule.

The tank design includes a top inlet, bottom outlet, rotating cleaning ball, 0.22 µm vent filter and level detection. These features support water transfer, internal cleaning and level monitoring. For a complete line, storage and transfer should be coordinated with the demand of the PET bottle water filling machine.

• Top inlet and bottom outlet
• 360° rotating cleaning ball
• 0.22 µm vent filter and liquid-level detection

Selection points: Confirm the working volume, tank position, inlet and outlet connections, and access for cleaning before finalizing the layout.

02 / Pretreatment

Multi-Media Filters

Media filtration prepares raw water for downstream treatment by reducing suspended impurities. Quartz sand, manganese sand and activated carbon are available media options; the appropriate combination depends on the water analysis and the purpose of each filtration stage.

Backwashing removes accumulated material from the filter bed and forms part of routine maintenance. Media filtration should be designed together with the downstream cartridge filters and membrane equipment, rather than treated as a complete purification process on its own.

• Media choices for the selected treatment process
• Backwashing for filter maintenance

Selection points: Confirm the raw-water condition, required flow, selected media and the water and drainage arrangements for backwashing.

03 / Pretreatment

Water Softeners

Water softening is considered when hardness could contribute to scaling in downstream equipment. Conventional ion-exchange softening reduces calcium and magnesium hardness; whether this step is required depends on the water analysis and the selected treatment process.

A softener is one possible pretreatment option for a membrane filtration system. The resin, vessel arrangement, regeneration method and operating settings are selected during project design. Share your raw-water report for a pre-sale treatment review before confirming the configuration.

Selection points: Confirm the feed-water hardness, required flow, operating hours and regeneration requirements during selection.

04 / Filtration

Precision Cartridge Filters

Precision cartridge filters provide a replaceable filtration stage before membranes or other downstream equipment. They capture particles according to the selected element and help reduce the particulate load reaching the next treatment stage.

The stainless-steel vessel can be configured with PP meltblown, wire/sintered, pleated or titanium elements. The filtration rating and element arrangement should suit the feed water and the requirements of the downstream UF, NF or RO system. Selection also needs to account for inspection and cartridge replacement.

• Stainless-steel filter vessel
• PP meltblown, wire/sintered or pleated elements
• Titanium cartridge option

Selection points: Confirm the required filtration rating, water flow, operating conditions and access for element replacement.

05 / Ultrafiltration

Hollow-Fiber Ultrafiltration

Hollow-fiber ultrafiltration uses membrane modules to separate suspended particles and larger molecules. It can serve as the main filtration stage in a suitable treatment process, or as pretreatment before reverse osmosis or nanofiltration.

The described system includes forward flushing, backwashing, air scouring and online disinfection. Cleaning sequences should match the feed-water conditions and membrane requirements. UF does not provide the same dissolved-salt reduction as RO; review the RO vs UF treatment guide when defining the finished-water specification.

• Automatic forward flushing and backwashing
• Air scouring
• Online disinfection

Selection points: Confirm the source-water analysis, required treated-water flow and the flushing, backwashing and cleaning arrangements.

06 / Membrane treatment

Membrane Filtration Systems

Membrane filtration systems can be configured with rolled ultrafiltration, nanofiltration or reverse osmosis for mineral, spring and purified-water projects. The choice starts with the raw-water analysis and the required finished-water quality.

UF primarily separates particles and larger constituents; NF provides selective separation of dissolved components; RO is used for more extensive dissolved-salt reduction. Pretreatment, membrane selection, cleaning and downstream storage need to work together. Integrate the selected process with the water demand and operating schedule of the complete bottled water production line.

Selection points: Confirm the required water quality and flow, available feed-water supply, membrane recovery where applicable, utilities and wastewater handling.

07 / Ozone mixing

Ozone Mixing Systems

Ozone mixing systems introduce ozone into water and promote gas–liquid contact as part of the selected disinfection process. The described arrangement combines a gas–liquid mixing pump with pipeline mixing in a compact configuration.

Multi-unit and single-tank arrangements are available for different installation requirements. Concentration control should be coordinated with water flow and the treatment process. Dosing, contact conditions and monitoring need to be defined during process design; the guide to bromate risk during ozone disinfection explains the water-quality checks involved.

• Gas-liquid mixing pump and pipeline mixing
• Multi-unit and single-tank configurations
• Ozone concentration control

Selection points: Confirm the water analysis, required flow, installation space, dosing controls and monitoring requirements.
