Flocculation Test Unit – HydraNexis HNX 10

A CE-certified precision laboratory apparatus for engineering experimentation and technical education, manufactured by Scientico India to ISO 9001:2015 standards. Supplied with calibration certificate, operation manual, and complete export documentation. Designed for Water Treatment Technology laboratories in engineering colleges and technical institutions.

The Flocculation Test Unit (HydraNexis HNX 10) by SCIENTICO is a compact, bench-top laboratory system designed for coagulation and flocculation (jar test) studies, which are essential preliminary tests before designing or optimizing water and wastewater treatment plants. The unit enables simultaneous testing under controlled and repeatable conditions to determine optimal treatment parameters. Product Overview Before full-scale implementation of a water or wastewater treatment process, coagulation and flocculation tests are carried out to determine the most effective chemical dosages, pH conditions, and mixing regimes. The HydraNexis HNX 10 allows these evaluations through six parallel jar tests, providing reliable comparative results in a single experimental run. Jar tests are widely used in treatment plants to optimize daily operations. They help identify:
  • Optimum coagulant dosage
  • Required pH adjustment
  • Effectiveness of activated carbon addition
  • Floc formation rate and settleability
  • Water clarity and filter run performance
The system enables the study of flocculation kinetics, aggregation rate as a function of energy input (stirrer speed), floc settleability, and filterability index. Each vessel is equipped with an independently controlled stirrer, allowing precise adjustment of mixing speed and intensity. All paddle shafts are made of stainless steel to prevent corrosion. The stirrer assemblies are removable, making it easy to remove beakers, clean the system, and prepare for subsequent experiments. Integrated LED illumination and a digital touch LCD control panel enhance visibility and ease of operation.
