Industrial Water Treatment Design Guide | Beta Pramesti
Design industrial water treatment from raw-water analysis through process selection, sizing, commissioning, and detailed proposal-comparison criteria.
Industrial water treatment is a process train selected from raw-water quality and the required product-water specification, not a standard equipment package. PT Beta Pramesti Asia designs treatment from pretreatment and filtration through ion exchange, membranes, disinfection, and polishing using flow data, load variation, quality targets, and operating limits.
Water Treatment: Modern Water Purification Solutions by Beta Pramesti Asia
An industrial water treatment plant combines physical, chemical, and membrane processes to meet a defined product-water duty. The correct train follows the measured raw-water load, peak flow, downstream OEM limits, recovery target, residuals route, and operating philosophy—not a generic list of equipment.
What is a Water Treatment?
A water treatment plant is an installation or facility that aims to treat raw water or wastewater into water with a quality that is suitable for use in various purposes, such as industry, households, and food and beverage manufacturing processes. This system involves a series of physical, chemical, and biological processes to remove contaminants, impurities, and harmful particles from water.
Drinking-water duty must be separated from process-water duty. Where the product will be consumed directly in Indonesia, the project specification should review Ministry of Health Regulation No. 2 of 2023 and every other requirement applicable to that facility. Boiler, cooling, manufacturing, and high-purity users may impose tighter limits on specific parameters through OEM or process specifications.
In order to produce the best quality water, a water treatment plant usually consists of several stages, ranging from initial filtration, coagulation, filtration, to final stages such as disinfection or water quality polishing. Many factories or industrial facilities now rely on water treatment plant technology to reduce the cost of purchasing clean water and minimize liquid waste that is harmful to the environment.
Why is Water Treatment Important?
A water treatment plant stabilizes process-water quality when source conditions and production loads change. A system with a documented water balance and acceptance criteria can also control water use, operating cost, equipment risk, and environmental obligations. Target outcomes include:
- Reduce groundwater or surface water consumption.
- Save on production costs involving water.
- Maintain compliance with environmental regulations.
- Reduce wastewater contamination to the environment.
- Support the concept of green industry.
PT Beta Pramesti Asia supports evaluation, design, fabrication, installation, commissioning, and maintenance of industrial water-treatment systems against agreed project data and water-quality targets.
Raw-water data that controls the design
One laboratory result cannot represent a source that changes with season, tides, rainfall, production, or well operation. Use dated results from normal and credible worst conditions, with the sample point and method recorded.
| Design input | Minimum data | Decision affected |
|---|---|---|
| Source and variation | Surface water, well, municipal, brackish, seawater, or reuse; seasonal and operating data | Equalization, redundancy, materials, and upset risk |
| Flow | Average and peak m³/h, peak duration, daily volume, and batch pattern | Hydraulic capacity, storage, turndown, and number of trains |
| Solids and colloids | Turbidity, TSS, particle size, and SDI when RO is considered | Clarification, media filtration, UF, cartridges, and backwash frequency |
| Salts and hardness | Conductivity/TDS, hardness, alkalinity, chloride, sulfate, and silica | Softening, antiscalant, RO/NF, demineralization, recovery, and materials |
| Metals and organics | Iron, manganese, TOC/COD, oil, colour, odour, and source-specific contaminants | Oxidation, activated carbon, coagulation, or a specialist process |
| Microbiology | Total coliform/E. coli or process-relevant indicators | Barriers, sanitation, UV, chlorination, and residual monitoring |
| Product-water specification | Limit for each parameter, end use, availability, and operating hours | Acceptance testing and final polishing technology |
Source-to-treatment decision map
Start with the condition that must be controlled, then arrange barriers in sequence. This table is an initial screening map; the final train must be supported by analysis, mass balance, treatability testing, and downstream OEM limits.
| Dominant feedwater condition | Initial train to evaluate | Evidence required before selection |
|---|---|---|
| Rapidly changing turbidity/TSS in surface water | Screening → coagulation/flocculation → clarifier or lamella → media filter → cartridge/UF | Seasonal jar tests, sludge yield, filter run, and turbidity/SDI target |
| High hardness with acceptable TDS | Media filtration if needed → softener | Hardness leakage, regeneration demand, salt storage, and peak flow |
| High TDS, chloride, or silica in brackish water | Pretreatment → cartridge/UF → brackish-water RO → target-specific polishing | Scaling projection, SDI, recovery, reject route, and permeate test |
| Seawater | Intake/screening → coagulation/filtration or UF → cartridge → seawater RO → remineralization/disinfection as needed | Salinity/turbidity variation, biofouling risk, materials, energy, and brine disposal |
| Demineralized or high-purity water | One/two-pass RO → EDI, mixed bed, or demineralizer | Conductivity/resistivity, silica/boron where relevant, regeneration, and recovery |
| Product requires a microbiological barrier | Adequate filtration → ultraviolet or chemical disinfection → residual monitoring | UV transmittance, validated/OEM dose, contact time, demand, and point of use |
| Reuse from treated wastewater | Equalization → solids/organics polishing → UF/RO as required → disinfection | Effluent variation, fouling test, microbial risk, concentrate route, and site reuse permission |
Compare processes before fixing the configuration
No single technology removes every contaminant. Select each process for its primary function and incoming load; expensive polishing must not compensate for inadequate pretreatment.
| Process | Primary duty | Does not solve alone | Core sizing data |
|---|---|---|---|
| Coagulation, clarification, lamella | Reduce colloids, turbidity, colour, and solids that can form floc | Dissolved salts and non-coagulable dissolved organics | Peak flow, jar test, surface loading, sludge rate |
| Media filtration | Retain solids after pretreatment or from a stable source | TDS, dissolved hardness, or microbes without another barrier | Service flow, bed depth, particle load, backwash flow |
| Ultrafiltration | Barrier for suspended solids and some microorganisms | Dissolved salts | Tested flux, TMP, recovery, backwash/CIP, feed variation |
| Softening/ion exchange | Remove hardness or selected ions | Total TDS; resin also needs regeneration and brine management | Ionic load, leakage target, vessel duty, regenerant dose |
| RO/NF | Reduce dissolved ions and membrane-rejected contaminants | Poor pretreatment, incompatible free chlorine, or concentrate disposal | Flux, recovery, scaling, temperature, pressure, normalized performance |
| Activated carbon | Reduce chlorine, taste/odour, and selected organics | All ions or all microorganisms; unmanaged beds can support growth | EBCT, contaminant load, breakthrough, backwash/sanitation |
| UV/chemical disinfection | Control microorganisms under design conditions | High turbidity, deposits, or downstream recontamination | UVT/dose or CT, peak flow, residual demand, validation |
Sizing and vendor data-package checklist
A request for quotation must state the design basis, not only “20 m³/h capacity.” Include:
- PFD and source of every stream, including returns, recycle, backwash, drains, and concentrate.
- Average, peak, and minimum flow; peak duration; operating hours; and duty/standby requirement.
- Normal and worst credible raw-water analyses with date, unit, method, and sample point.
- Product-water limits for every mode, including downstream OEM requirements.
- Footprint, elevation, electricity, instrument air, chemical storage, area classification, and materials.
- Water balance covering recovery, backwash, regenerant, reject, sludge, and disposal routes.
- Control philosophy covering online instruments, alarms, interlocks, automatic shutdown, sampling, and historian.
- FAT/SAT, performance test, training, consumables, critical spares, and as-built documentation.
For injection packages, review chemical-metering dosing pumps and water-treatment ancillaries. Where a project only needs replacement membranes, resin, filter media, or housings, Watermart supplies water-treatment components in Indonesia.
How do you compare industrial water treatment proposals?
Compare proposals against one common design basis, not equipment count or headline flow alone. Each bidder should state the feedwater envelope, guaranteed product quality, net product capacity, recovery, residual streams, utility demand, exclusions, and acceptance method in the same units and operating cases.
| Comparison item | What the proposal must state | Buyer check |
|---|---|---|
| Design basis | Dated feed analysis, normal and worst case, temperature, average/peak flow, operating hours, and product limits | Confirm every bidder used the same input revision and boundary conditions |
| Net capacity and availability | Net product flow after backwash, regeneration, cleaning, and internal recycle; duty/standby arrangement and turndown | Separate gross equipment rating from usable plant output |
| Performance guarantee | Parameters guaranteed, sampling point, test method, stabilization period, feedwater envelope, and remedy if the test fails | Reject guarantees that apply only to undefined or ideal feed conditions |
| Water balance and residuals | Product recovery, backwash, regenerant, concentrate, sludge, and spent cleaning stream by operating case | Confirm storage, treatment, reuse, and disposal interfaces are included |
| Operating demand | Connected and normal power, chemical and regenerant basis, consumables, labour assumptions, and cleaning frequency | Compare lifecycle inputs on the same annual operating basis |
| Scope and interfaces | Civil works, tanks, piping limits, cabling, instruments, controls, utilities, installation, freight, taxes, and site services | Assign every interface once and identify exclusions before award |
| Testing and support | FAT, SAT, performance test, training, manuals, critical spares, warranty boundary, and response scope | Tie payment and handover milestones to documented acceptance evidence |
Normalize these items in a bid-comparison sheet and return technical deviations for clarification before ranking price. For a project review, send the common design basis and bidder scope to the PT Beta Pramesti Asia team.
Commissioning and performance-acceptance criteria
Commissioning is complete when the system demonstrates capacity, quality, recovery, and stable operation under the agreed conditions—not merely when its pumps start. The acceptance protocol must record actual feedwater and distinguish it from the design basis.
| Verification area | Criterion to write into the contract |
|---|---|
| Safety and mechanical | Hydro/leak test, rotation, alignment, guards, chemical bund, drains, labels, and maintenance access complete |
| Instrumentation | Flow, pressure, level, conductivity, turbidity, pH, ORP, and other analyzers calibrated; alarms and interlocks challenged |
| Hydraulics | Minimum/normal/peak flow, pressure drop, backwash, recycle, tank working volume, and overflow demonstrated |
| Water quality | Every product parameter tested at the agreed point and method over the contractual stable period |
| Consumption | Energy, chemicals, regenerant, backwash, recovery, sludge, and concentrate compared with guarantees |
| Operability | Start/stop, turndown, duty/standby changeover, cleaning, regeneration, sampling, and upset response demonstrated |
| Handover | SOP, cause-and-effect, as-built P&ID, datasheets, material certificates, commissioning log, spares, and training accepted |
Reject, backwash, sludge, and spent cleaning chemicals belong in the site’s waste balance. Government Regulation No. 22 of 2021 covers water-quality protection and waste management; each disposal route must follow the facility’s environmental approval and the correct sector-specific limits rather than be assumed suitable for direct discharge.
