The overview
A leading Indian FMCG company known for its diverse product range needed to procure a clarifier for their water treatment plant in Gujarat. Their existing water treatment plant (WTP) required cleaner influent water. We were tasked with procuring and installing a clarifier unit to pre-treat the raw water before it entered the WTP. The clarifier needed to handle a flow rate of 120,000 to 140,000 kilolitres per day (KLD). The main goal was to reduce turbidity and hardness. Here is how Venwiz tackled this unique clarifier vendor procurement.
Here is a table summarising the desired water quality
| Water Characteristic | Input | Output |
|---|---|---|
| Turbidity (Nephelometric Turbidity unit) | 67 | 10-15 |
| Conductivity(total dissolved solids) | 200 | 200 |
| Hardness (parts per million) | 100 | 50 |
| Ph | 7.2 | 6-8 |
What is a clarifier?
A clarifier is essentially a large settling tank. They play a crucial role in water treatment plants and remove solid particles and impurities from the water using gravity. These tanks play a vital role in water treatment facilities by helping to remove impurities and solid waste before the raw water proceeds for further treatment.These clarifiers use gravity to allow the solids to settle at the bottom of the tank, while they collect the clarified water from the top.
Challenges
- Budgetary Restrictions: The client had a limited budget for the clarifier, requiring a cost-effective solution that wouldn’t compromise performance.
- Tight Delivery Schedule: The project demanded a rapid turnaround, requiring us to find a vendor to complete delivery and installation within one month on a turnkey basis.
- Vendor Expertise: The chosen vendor needed to be a manufacturer with proven experience in designing, manufacturing, supplying, and installing clarifiers.
Vendor attributes
The selection process for the clarifier vendor focused on the following key attributes:
- Manufacturer: The vendor had to manufacture water treatment systems with expertise in clarifier design and construction.
- Experience: A proven track record of designing, manufacturing, supplying, and installing clarifiers for raw water treatment projects exceeding 120 KLD capacity was essential.
- Client testimonials: We sought client references to confirm the vendor’s ability to deliver projects on time and within budget while meeting performance specifications.
Solution
The project addressed the challenges through the following steps:
- Vendor Identification: We started with an initial pool of 6-7 potential vendors.
- Negotiation and Evaluation: We conducted negotiations with each vendor, focusing on the technical capabilities and cost-effectiveness of the clarifier.
- Client Preference and Review: While the client had a preferred vendor, the negotiation process revealed a new vendor who could meet their technical requirements and budget constraints. We obtained client references and testimonials to confirm the vendor’s past performance and reliability.
Impact
The project delivered several significant benefits:
- Cost-Effectiveness: The client secured a clarifier unit that met their technical needs while adhering to their budget limitations.
- Timely Delivery: The vendor completed the project in a month, minimising disruption to the WTP’s operations.
- Improved Water Quality: The new clarifier effectively reduced raw water turbidity to the desired range (10-15 NTU), enabling efficient further treatment within the existing WTP.
- New Vendor Relationship: Expanding their vendor pool, the client gained access to a new, qualified supplier for future water treatment needs.
