Water Treatment Lab Equipment: Complete Guide for Engineering and Environmental Colleges
Water treatment lab equipment forms the core of environmental engineering, civil engineering, and process engineering curricula. This guide covers the complete range of water treatment training apparatus, from coagulation-flocculation to membrane filtration, with experiment descriptions, specifications, and procurement guidance for institutions requiring CE-certified equipment for AICTE, NBA, ABET, or CAA accreditation.
Water Treatment Process Flow
A complete water treatment laboratory replicates the stages of a municipal water treatment plant:
- Screening and sedimentation, removal of suspended solids
- Coagulation and flocculation, jar test for chemical dosing
- Filtration, slow sand, rapid sand, multimedia filtration
- Disinfection, chlorination, UV treatment
- Advanced treatment, reverse osmosis, ion exchange, adsorption
Water Treatment Lab Equipment List
1. Jar Test Apparatus (Coagulation-Flocculation Unit)
Determines the optimum coagulant dose (alum, FeCl₃, PAC) and pH for water treatment by simultaneously running 4–6 jar tests at controlled mixing speeds.
- Key experiments: Optimum coagulant dose determination; optimum pH for coagulation; settling rate measurement; turbidity removal efficiency
- Features: 4 or 6 gang stirrer, variable speed 0–200 rpm, timer, 1-litre square jars
2. Sand Filter Unit (Rapid and Slow Sand Filter)
Transparent column filters demonstrating rapid and slow sand filtration mechanisms, the primary physical treatment step in conventional water treatment.
- Key experiments: Filtration rate vs. head loss; turbidity and suspended solids removal; backwashing procedure; filter clogging and breakthrough
- Features: Transparent acrylic column, inlet and outlet pressure tappings, sampling ports at different depths
3. Reverse Osmosis (RO) Demonstration Unit
Bench-scale RO system demonstrating membrane separation for dissolved solids removal, the key technology in desalination and industrial water purification.
- Key experiments: Salt rejection measurement; permeate flux vs. pressure; energy consumption; comparison of feed vs. permeate TDS
- Features: Spiral-wound RO membrane, pressure gauge, flow meters, conductivity meter for TDS measurement
4. Ion Exchange Demonstration Unit
Demonstrates softening of hard water using cation and anion exchange resins, the standard process for boiler feed water treatment and industrial applications.
- Key experiments: Hardness removal; breakthrough curve; regeneration; demineralisation of water
5. Sedimentation Tank Model
Transparent rectangular settling tank with adjustable inlet, outlet, and baffles for studying discrete and flocculent particle settling in primary and secondary clarification.
- Key experiments: Settling velocity vs. particle size; surface overflow rate; zone settling; sludge blanket formation
6. Aeration Unit
Demonstrates oxygen transfer from air to water, critical for biological treatment (activated sludge) and iron/manganese removal in groundwater treatment.
- Key experiments: Oxygen transfer rate (OTR) vs. airflow; KLa determination; DO saturation vs. temperature
