The Process

Precision, twice over.

Two governed processes stand behind every bottle: a five-stage purification sequence that defines the water, and a six-stage washing and filling operation that prepares the vessel. Both are specified, measured, and repeatable.

01 — The Production Process

Follows a stringent multi-stage purification and quality control process to ensure that every bottle of drinking water meets the highest standards of safety, purity, and taste.

Stage 01 / 05

Sediment

5 μm → 1 μm cartridge cascade

Removes suspended solids before membrane contact.

Stage 02 / 05

Carbon

Granular + block dual bed

Adsorbs chlorine, VOCs, and taste-active organics.

Stage 03 / 05

RO membrane

0.0001 μm polyamide, 10–12 bar

Primary desalination; 98.5% mean TDS rejection.

Stage 04 / 05

UV + ozone

40 mJ/cm² UV dose

Post-membrane microbial control prior to fill.

Stage 05 / 05

Remineralize

Ca / Mg balance, pH 7.0–7.4

Stable mineral profile for commercial taste targets.

02 — Bottle Washing & Filling

PEARL DROPS® uses high-quality refillable 5-gallon bottles sourced from approved suppliers. Before filling, every bottle is thoroughly cleaned using a fully automated 900 Bottles Per Hour (BPH) washing and filling system.

Each bottle passes through a six-stage washing process comprising:

  1. 1

    External brush wash

    Mechanical brushing removes surface dirt, label residue, and external contaminants.

  2. 2

    Pre-rinse

    Recycled-water pre-rinse flushes loose debris from interior and exterior.

  3. 3

    Hot detergent wash

    Heated caustic detergent cycle dissolves organic film and biofilm risk.

  4. 4

    Disinfectant rinse

    Sanitizing solution contacts all internal surfaces under controlled dwell time.

  5. 5

    Purified-water final rinse

    RO-quality rinse removes residual chemistry before fill.

  6. 6

    Drip-dry & inspection

    Drain and visual/sensor inspection; bottles failing checks are rejected from the line.

Following the washing cycle, bottles are automatically filled with purified water under hygienic conditions, sealed, inspected, and prepared for distribution. The entire washing and filling operation is fully automated, minimising human contact and ensuring consistent product quality, hygiene, and operational efficiency.

03 — Quality Control

Measured at every step.

Quality is not inspected at the end; it is controlled throughout. Purification runs to defined specifications — 0.0001 μm filtration at 10–12 bar, a 40 mJ/cm² UV dose, remineralization to pH 7.0–7.4. Bottles failing washing inspection are rejected from the line. Every bottle is sealed and inspected before distribution.
