Sedimentation Tank – HydraNexis HNX 11
The Sedimentation Tank Pilot Plant ( ) by SCIENTICO is a laboratory-scale experimental system designed to demonstrate gravity sedimentation and hydraulic behavior in settling tanks. Made by Scientico India, ISO 9001:2015 certified, and supplied with a calibration certificate and operation manual.
Product Overview
Sedimentation is a fundamental unit operation in water and wastewater treatment for removing suspended solids. The HydraNexis HNX 11 provides a controlled environment to study settling tank hydraulics, sediment removal, flow regimes, and dispersion effects. Feed water is supplied from the laboratory mains and measured using a flow meter. A slurry with known concentration is prepared in a sump tank and injected into the fresh water stream before entering the settling tank. Continuous stirring in the sump tank prevents solids from settling before entering the sedimentation tank. A dye injection system enables hydraulic tracer studies, allowing visualization of flow patterns, short-circuiting, and dead zones. The system supports comparative analysis using Imhoff cones or sedimentation research devices.Request Specifications & Pricing
