Why Jar Testing Matters for Water Treatment
Optimum coagulant dose (alum, PAC, ferric chloride, polymer) varies with raw water quality (turbidity, alkalinity, pH, organics, temperature). Overdosing wastes chemistry and generates excess sludge. Underdosing lets floc pass into filters and causes finished-water turbidity. The jar test simulates full-scale coagulation → flocculation → sedimentation in a benchtop 6-jar array, dosing each jar with a different coagulant amount, running standard mixing energy profile (rapid mix 100 RPM × 30 sec → slow mix 30 RPM × 15 min → settle 15 min), then measuring residual turbidity to find the dose that gives lowest residual at lowest cost. Municipal and industrial water plants run this test daily; changes in raw water source (rain events, algal blooms, seasonal shifts) require dose re-optimization. Method 2540 and AWWA Standard Methods 2560 recognize jar testing as the primary coag optimization technique.

Standard Jar Test Method
- Fill each jar with 1000 mL of raw water sample
- Dose different coagulant amounts in each jar (e.g. 10 / 20 / 30 / 40 / 50 / 60 mg/L alum)
- Rapid mix at 100 RPM for 30 seconds (simulates plant flash mixer)
- Slow mix at 30 RPM for 15 minutes (simulates plant flocculator)
- Stop paddles: allow 15-30 minutes settling
- Sample supernatant from each jar, measure residual turbidity (NTU)
- Plot residual turbidity vs coag dose: optimum dose = lowest residual turbidity and minimum coag cost
Applications
- Municipal drinking water treatment plants: daily coagulant optimization
- Industrial wastewater treatment: food processing, pulp and paper, textile dye, mining, chemical plants
- Stormwater treatment: construction runoff, agricultural runoff
- Environmental testing laboratories: contract water testing and treatability studies

- Cooling tower and boiler water treatment: makeup water coag prior to demineralization
- Aquaculture and fish farm water treatment
- University and college civil / environmental engineering programs: teaching lane equipment
- NGO and humanitarian water treatment: emergency and refugee water treatment training

FAQ
How does this compare to Phipps & Bird PB-700?
Feature parity, 5-150 RPM digital variable speed, individually removable paddles, cold-light illuminator base, 6-jar configuration. Phipps & Bird PB-700 has slightly more polished operator interface and integrated timer. Price differential: $1,999 (6-jar) vs $4,500-$6,500 for PB-700. For municipal plants and universities, our unit delivers full method compliance at 30-40% of P&B pricing.
What jar size does this use?
Standard 1000 mL round beakers (B34 pattern), compatible with standard AWWA jar test method. 6 × 1000 mL beakers included in 6-jar configuration.
How do I select 2 / 4 / 6 jar variant?
Select at checkout. 2-jar for benchtop screening and small water plants. 4-jar for standard mid-size plant coag optimization. 6-jar for full method-of-standard-additions (most municipal water plants and universities standardize on 6-jar).
What voltage do I need?
Specify 110V/60Hz (US standard) or 220V/50Hz (international) at order. Email sales@scimedstore.com if uncertain.
Can I use square jars instead of round beakers?
Square jars (2-liter Phipps & Bird style) provide slightly better flocculation dynamics but round 1000 mL beakers are AWWA standard method compliant. Round beakers are cheaper and universally available. Square jars available as accessory upgrade on request.
