DAF CHEMICALS & PROCESS OPTIMIZATION
Better DAF performance starts with chemistry, dosage, feed conditions and equipment operation working together.
Watermen evaluates actual industrial wastewater and develops practical treatment recommendations based on the sample, the process and the agreed service scope.
SAMPLE EVALUATION & JAR TESTING
Watermen can evaluate customer samples in the lab or perform testing onsite when appropriate. Jar testing compares treatment approaches and dosage ranges using the facility’s wastewater. Depending on the application, testing may include polymers, coagulants, flocculants, pH adjustment and other targeted treatment steps.
POLYMER, COAGULANT & FLOCCULANT PROGRAMS
Polymer selection and dose evaluation
Coagulant and flocculant sequence review
Floc formation and separation observations
pH and mixing-condition review
Chemical-feed pump, feed-rate and feed-point review
DAF troubleshooting for carryover, weak floc, excess sludge or high chemical use
Selected treatment chemicals or feed equipment when included in the agreed program
FROM SAMPLE TO PLANT
Review the wastewater and process. Watermen gathers available flow, chemistry, equipment and operating information.
Test promising treatment approaches. Candidate products and dosage ranges are compared using representative wastewater.
Document observations. Results, photographs and relevant limitations are recorded.
Recommend a practical starting point. Watermen outlines chemistry, dosage and feed considerations for the facility to evaluate.
Support onsite implementation. When included in the scope, Watermen can assist with feed adjustment, DAF troubleshooting, monitoring and operator guidance.
PROCESS CONDITIONS & LIMITATIONS
Bench or jar-test results provide a useful basis for treatment decisions, but full-scale performance also depends on wastewater variability, flow, pH, mixing, feed location, recycle conditions, equipment condition and operator control. Additional laboratory analysis may be needed when visual separation alone cannot confirm changes in target constituents.

FRACKING WATER TREATMENT — BEFORE & AFTER
This fracking-water sample was treated using caustic for pH adjustment, a metal precipitant, coagulant and flocculant. The treatment formed settleable solids and produced visibly clearer water in bench testing.
Watermen uses this same site-specific testing process to select chemistry and dosage before recommending a full-scale treatment program.
