Industrial Liquid PAC: Price & Dose | Beta Pramesti Asia

Industrial liquid PAC is a ready-to-dose coagulant for water and wastewater plants, but demand and price depend on grade, active content, jar-tested dose, volume, tank facilities, location, and delivery pattern. Compare cost per m³ of water meeting the target rather than product price per kilogram alone.

PT Beta Pramesti Asia, through beta.co.id, supplies liquid PAC and application support for industrial process water, raw water, and wastewater treatment in Indonesia. Buyers can compare liquid and solid PAC, ACH, or another coagulant on the same samples and treated-water targets.

Factors that determine liquid PAC pricing

Factor	Cost effect
Grade, active content, and basicity	Establishes the quality and comparative-dose basis
Jar-tested dose	Converts price per kg into consumption and cost per m³
Volume and delivery pattern	Defines packaging, supply frequency, and safety stock
Tank and dosing system	Affects transfer, dilution, materials, and calibration needs
Unloading location	Affects delivered cost and access requirements

Which data belong in a liquid PAC quotation?

The name “liquid PAC” is not enough to compare two products. Each quotation should identify the grade and specification basis so dose, tank capacity, consumption, safety, and price can be assessed consistently.

Quotation data	Why it matters	Evidence to request
Product duty and grade	Separates process-water, wastewater, and other intended uses	TDS and grade statement
Active content and basicity	Establishes a common comparison basis	Specification and batch CoA
Density and form	Converts mass feed into pump volumetric flow	TDS, CoA, and reference temperature
Product pH and compatibility	Affects tank, pipe, seal, and pump materials	SDS and wetted-material list
Packaging, volume, and lead time	Defines unloading, safety stock, and delivery frequency	Commercial offer and logistics plan
Tested dose	Converts price per kg into cost per treated m³	Documented jar test and plant trial

Do not use a generic specification range from the internet as the purchase basis. Active content, basicity, density, impurities, grade, storage, and shelf life should come from the exact product and batch being offered.

How should liquid PAC, solid PAC, and ACH be compared?

Buyer question	Liquid PAC	Solid PAC	ACH	How to decide
Dosing readiness	Can reduce dissolution work	Requires controlled make-down	Depends on product form	Audit tanks, mixing, pumps, and operators
Logistics	Transports product with its water content	More concentrated for transport	Depends on grade and concentration	Calculate delivered cost and storage
Water response	Not universal	Not universal	Not universal	Jar test on the same sample, pH, and temperature
Alkalinity/pH effect	Depends on grade and dose	Depends on grade and dose	Often tested where buffering is limited	Measure before and after testing
Total cost	Product, handling, dosing, and sludge	Dissolution, labour, dust, and sludge	Product, dosing, and sludge	Compare cost/m³ at one water target

Use the PAC water-treatment guide for jar-test method and the ACH water-treatment guide for a pre-hydrolysed comparison. Testing should assess turbidity or TSS, colour/organics where relevant, pH, alkalinity, floc size and strength, separation time, residuals, sludge volume, and filtrate quality.

For application evidence, read the 17% liquid PAC optimization case at a water treatment plant. It compares product dose, sedimentation turbidity, dissolution work, operator exposure, and monthly chemical cost under one documented operating condition.

How should liquid PAC demand and cost be calculated?

State dose consistently as commercial product:

Product demand (kg/h) = dose (mg/L) × flow (m³/h) ÷ 1,000

Chemical cost (currency/m³) = dose (mg/L) × delivered price per kg ÷ 1,000

Add alkali, flocculant, make-down labour, mixing energy, sludge treatment, delivery, and stock losses for a total-cost comparison. Calibrate the chemical dosing pump with actual product density and conditions rather than stroke position alone.

What should be checked when liquid PAC performance is unstable?

Symptom	First checks	Evaluation response
Floc does not form	Actual dose, pH, alkalinity, mixing, and water change	Repeat a dose/pH sweep before raising dose
Floc breaks	Shear, injection order, dosing point, and flocculation time	Test mixing and injection location
Sludge rises sharply	Dose, influent solids, polymer, and sludge withdrawal	Compare sludge mass at the same water target
Pump loses capacity	Density, viscosity, valves, tubing, calibration, and level	Restore delivery before changing the programme
Filtrate quality declines	Coagulation, separation, filter loading, and backwash	Audit the clarifier or DAF with the chemistry

Frequently asked buyer questions about liquid PAC

Does liquid PAC always dose lower than alum?

No. Response depends on product grade and water characteristics. Compare dose and total cost under the same test procedure; do not assume one form is always superior.

Which documents should arrive with the product?

Request the TDS, SDS, batch CoA, grade information, packaging, storage, shelf life, and handling instructions. These records support receiving, compatibility, and batch traceability.

Which data are needed for an evaluation?

Send the water source and flow, pH, alkalinity, turbidity/TSS, colour, COD/TOC where relevant, current coagulant/dose, water target, jar-test results, dosing facilities, monthly demand, location, and sludge route through the Beta contact page.
