Globaluf’s engineering team recently completed the live commissioning and formal handover of a custom industrial groundwater purification plant in Johor, Malaysia. Extracted from a 270m deep borehole, the raw water carries heavy concentrations of mud, silt, and sand, resulting in persistent turbidity levels consistently exceeding 50NTU.

Step-by-Step Chemical Dosing & Process Logic
To prevent rapid membrane fouling and ensure continuous operation, Globaluf implemented a 3-stage pre-treatment and filtration chain:
Stage 1: Chemical Coagulation & Lamella Clarification
Primary Dosing Tank (Coagulation): Polyaluminum Chloride (PAC) is dosed to bind colloidal particles. Sodium Hydroxide (NaOH) is added to optimize pH for maximum flocculation efficiency, alongside Sodium Hypochlorite (NaClO) for microbial disinfection.
Secondary Dosing Tank (Flocculation): Polyacrylamide (PAM) is introduced to expand floc size.
Inclined Plate Settler (Lamella Clarifier): Water flows through a honeycomb lamella media basin where heavy flocs settle out rapidly, dropping raw turbidity from > 50NTU to under 1.0NTU.

Stage 2: Ultrafiltration (UF) Membrane Barrier
Clarified water is stored in a 6m3 buffer tank before being pumped into hollow-fiber UF modules. The 0.01um pore size blocks residual suspended solids, colloidal silica, and bacteria, maintaining a Silt Density Index (SDI below 3.0).
The UF permeate feeds into the RO skid where high-pressure pumps force water through semi-permeable membranes. Operating live at an inlet conductivity of 652uS/cm (pH =8.0), the system achieved an exceptional 7.29uS/cm permeate conductivity (98.9% desalination rate) with a neutral pH of 7.0.
