Coagulant Water Treatment Indonesia | Beta Pramesti
Coagulant water treatment with BETAGARD PAC, ACH and POLYDADMAC. Compare jar-test dose, effluent quality, sludge load, plant trial and cost per m³ selection.
Short Answer
Coagulant water treatment from PT Beta Pramesti Asia supports raw-water clarification, process-water polishing, and industrial wastewater treatment in Indonesia. Compare BETAGARD PAC with ACH or POLYDADMAC by jar testing an actual sample, then confirm dose, effluent quality, floc formation, sludge impact, and cost per m³ in a plant trial.
The products on this page support clarification, turbidity, TSS and colour reduction, oil-water separation, DAF, and sludge conditioning. Chemical name and active content help screen candidates, but they do not replace testing under the facility’s actual process conditions.
Coagulants neutralize the charge of suspended particles so fine solids can form flocs that are easier to separate. A coagulation program is often paired with flocculants, sludge treatment, or broader water and waste water chemicals, depending on the raw water, wastewater character, and process unit.
Before selecting a product, use the chemical wastewater treatment method guide to map contaminants, process sequence, jar-test gates, residuals, and sludge consequences. If the programme also needs pH adjustment or bulk neutralisation, review industrial hydrochloric acid and commodity chemical supply before sizing tanks and dosing equipment.

PAC, ACH, or POLYDADMAC coagulants: when are they used?
| Operator question | Field condition | Relevant product or program | Data to check |
|---|---|---|---|
| Which supplier provides coagulants and flocculants for industrial wastewater in Indonesia? | TSS, turbidity, color, or oil is not dropping in a clarifier, DAF, or sedimentation process | The Betagard series on this page and flocculants | pH, alkalinity, turbidity, TSS, color, oil and grease, flow rate, and jar-test results |
| When should PAC be selected for raw water or process water? | An inorganic coagulant is needed for surface water, process water, or wastewater clarification | BETAGARD 4008, 4010, 4012, 4017, 4031, 4033, and PAC | Initial pH, PAC dosage, aluminum residual, turbidity before and after treatment, and floc formation |
| When should ACH or aluminum chlorohydrate coagulants be considered? | The process needs a high-Al2O3 coagulant or coagulant aid for liquid-solid separation | BETAGARD 4040, 4040 Series, 4041, 4044, and 4045 | Jar-test result, operating pH, sludge character, color, organic matter, and material compatibility |
| When is an organic POLYDADMAC coagulant used? | The system needs a primary coagulant or coagulant aid for clarification, DAF, filtration, centrifugation, or dewatering | BETAGARD 4050 and 4050 Series | TSS, color, oil and grease, separation unit type, sludge dry solids, and injection point |
For chemical injection equipment, see Beta dosing pumps or Watermart dosing pumps for water treatment. If the plant’s baseline coagulant is alum, use the PAC-versus-alum comparison to align test basis, pH, alkalinity, sludge, and programme cost before requesting a quotation.
RFQ data that determines a wastewater coagulant trial
A wastewater coagulant RFQ should define influent character, the separation unit, current chemistry, effluent targets, and sludge-handling limits. Those facts determine the candidates and test design; where the requirement is already specific to polyaluminium chloride, use the PAC coagulant supplier page to compare grades, packaging, and supply-price basis.
| RFQ data | Details to record | Decision affected |
|---|---|---|
| Wastewater profile | Waste source, continuous or batch operation, average/peak flow, pH, alkalinity, TSS, colour, oil and grease | Sample type, test range, pH correction, and chemical candidates |
| Current chemical programme | Product name, actual dose, solution concentration, injection order and point | Comparison baseline and whether a chemical should be replaced or paired |
| Separation unit | Clarifier, sedimentation, DAF, filtration, centrifugation, or dewatering | Required floc-formation speed, floc strength, and separation time |
| Dosing system | Tank capacity and material, mixer, pump, calibration result, and interlocks | Ability to handle the product form and maintain the true dose |
| Target and sludge route | Effluent target, sludge volume, withdrawal frequency, and dewatering response | Trial limits that avoid transferring the problem to sludge handling |
| Supply requirement | Monthly consumption, packaging, site location, unloading access, and safety stock | Quotation basis and supply schedule after a candidate passes the trial |
Coagulant jar-test acceptance table
A coagulant jar test is useful for quotation only when candidates are compared on the same sample, pH, mixing time, separation time, and quality target. Record the result as programme cost per m³ or per kg of TSS removed, not only as mg/L of product.
| Test evidence | How to normalize it | Decision boundary |
|---|---|---|
| Product dose | mg/L as supplied, solution concentration, and active content where available | Prevents liquid PAC, PAC powder, ACH, and POLYDADMAC from being compared on different bases |
| Water condition | Initial/final pH, alkalinity, TSS, colour, oil and grease, and temperature | Shows whether performance comes from coagulation or only pH correction |
| Floc formation | Floc speed, size, strength, and shear response | Selects a product that survives the actual mixer, pump, DAF, or clarifier |
| Treated-water quality | Turbidity, TSS, colour, oil and grease, COD where relevant, and metal residual | Connects the bench test to effluent or process-water targets |
| Sludge impact | Sludge volume, settleability, cake/filtrate if tested, and flocculant need | Avoids a choice that transfers cost to dewatering |
| Programme cost | Product, pH correction, polymer, sludge handling, and supply frequency | Defines the real cost after all supporting chemicals are counted |
To compare liquid PAC, PAC powder, ACH, and POLYDADMAC fairly, create two dose numbers: as-supplied product dose and active or Al2O3 basis where data are available. This matters because a product with a higher price per kg can still cost less when active content, pH correction, or sludge impact is better.
| Dose normalization | Practical formula | When to use it |
|---|---|---|
| As-supplied product | mg/L of product added to the sample | Daily consumption, stock, and delivered-price basis |
| Active or Al2O3 basis | mg/L product × active percentage | Comparing PAC/ACH grades without treating dilution water as active material |
| Cost per m³ | dose mg/L × flow m³/day × price/kg ÷ 1,000 | Estimating chemical cost at the same flow |
| Complete programme cost | coagulant + pH adjustment + flocculant + sludge handling | Selecting the programme with the true lower operating cost |
If two candidates reach the same effluent quality, choose the one that remains stable on normal and peak-load samples, not the one that looks clearest in a single beaker. For DAF or sludge applications, continue testing with sludge treatment so underflow, cake, and filtrate are included.
How should a jar-test result move to a plant trial?
A jar-test result should move to a plant trial only when dose, pH, injection sequence, and quality targets are written down. PT Beta Pramesti Asia usually asks for an operating baseline before the trial so a coagulant change is not confused with a change in flow, pH, TSS load, oil, or clarifier and DAF condition.
| Requirement before trial | Minimum evidence | Why it matters |
|---|---|---|
| Sample represents operation | Sampling time, flow, pH, TSS, colour, oil and grease, and production condition | Avoids choosing a product from a sample that is too light or too severe |
| Dose can be injected | Solution concentration, pump capacity, injection point, and mixing time | Confirms the test dose is actually delivered in the plant |
| Quality target is clear | Turbidity, TSS, colour, FOG, COD where relevant, and sludge limits | Defines when the trial is accepted or stopped |
| Sludge impact is counted | Sludge volume, settleability, polymer demand, cake, and filtrate | Prevents cost from moving from treated water to dewatering |

FAQ
Who supplies coagulants and flocculants for wastewater treatment in Indonesia?
PT Beta Pramesti Asia supplies Betagard coagulants in Indonesia for water clarification, wastewater treatment, DAF, oil-water separation, and sludge conditioning. Where stronger floc formation is needed, the coagulant program can be paired with flocculants.
What is the difference between PAC, ACH, and organic coagulants?
PAC on this page includes polyaluminum chloride products such as BETAGARD 4008, 4010, 4012, 4017, 4031, and 4033. ACH includes aluminum chlorohydrate products such as BETAGARD 4040, 4041, 4044, and 4045. Organic coagulants such as BETAGARD 4050 are based on POLYDADMAC and are used as a primary coagulant or coagulant aid for clarification, DAF, filtration, centrifugation, and dewatering.
Can coagulant dosage be selected directly from the product table?
No. The product tables help identify physical form, pH, active content, and packaging, but the actual dosage should be determined through a tube test or jar test in the laboratory and confirmed through a plant trial. pH, alkalinity, turbidity, TSS, color, oil and grease, flow rate, and sludge characteristics should be prepared before a dosage recommendation is made.
When should a plant contact Beta for a coagulation program review?
Contact Beta when clarification, DAF, filtration, or sedimentation is unstable; turbidity, TSS, colour, or oil remains high; flocs break; chemical use rises; or sludge is difficult to separate. Send the system data through Beta’s contact page so the product options and field-trial requirements can be reviewed.
Jar-Test Protocol for Coagulant Selection
A comparable jar test uses an actual sample, recorded initial pH, a fixed injection sequence, and the same mixing and settling times for every dose. The objective is not simply the lowest dose: it is the combination that produces stable treated water, separable floc and a sludge volume the downstream process can manage.
| Test step | Conditions to record | Decision criterion |
|---|---|---|
| Sample characterisation | pH, alkalinity, turbidity, TSS, colour, oil/grease and temperature | Establish whether PAC, ACH or an organic coagulant should be compared. |
| Rapid coagulation | Dose in each beaker, chemical order and mixing time | Reject doses that create fragile floc, move pH outside the process range or need impractical aid levels. |
| Flocculation and separation | Slow-mix time, settling or flotation time and supernatant clarity | Compare the outcome with the downstream clarifier, DAF, filtration or dewatering step. |
| Residual verification | Final pH, turbidity/TSS, colour and sludge character | Select candidates that meet the facility’s effluent target and its operational and sludge-management limits. |
| Field trial | Flow, injection point, actual dose and before/after trend | Confirm performance at normal and peak loading before changing the routine programme. |
Betagard coagulants can be paired with flocculants and a chemical dosing pump. Send the jar-test results, flow data and effluent target through Beta’s contact page so the recommendation can be checked against the actual process train.
Plant-Trial Decision Sheet for Coagulants
A jar-test candidate is not a routine programme until a plant trial proves water quality, unit operation, sludge impact and chemical use together. Establish a baseline before changing the programme, use an agreed dose window, and record feed conditions so results remain comparable across shifts.
| Trial evidence | Baseline to record | Requirement for acceptance |
|---|---|---|
| Influent and effluent quality | Flow, pH, turbidity/TSS, colour, oil/grease and sample time | The target is met on comparable samples, including the agreed loading conditions. |
| Chemical control | Product, batch, solution concentration, pump setting/calibration and injection point | Actual dose can be calculated and repeated; it does not rely on the pump-dial position alone. |
| Separation performance | Floc-formation time, settling/flotation, carryover and filter condition where relevant | Floc survives to the separation unit without creating a new downstream upset. |
| Sludge impact | Volume, withdrawal frequency, dry solids where measured and dewatering response | Better water quality does not overload the sludge-handling route. |
| Operating stability | Shift results, alarms, upstream changes, rain or production batch | The dose window has response limits and an agreed fallback setting when feed quality changes. |
| Measured cost | kg or L/day at the same flow and load | Compare cost per water volume or pollutant mass treated, not package price alone. |
Record the final decision as accepted, repeat required, or rejected, with the reason. Include the corresponding flocculant data when asking for review so the interaction between coagulation and floc formation is not assessed in isolation.
Technical reference: the U.S. EPA explains the roles of coagulation, flocculation, and jar testing in water treatment. Accessed 27 July 2026; wastewater-coagulant selection must still use the facility’s actual sample and process train.
