LAMELLA INCLINED PLATE CLARIFIER

INSTALLATION CASE STUDY

Introduction:

Reputed and leading Chlor Alkali Industry customer was looking for a Lamella in the plant. The plant

located in an Urban residential area was not having enough space and the challenge was to install the

new lamella in the limited available space.

For over 15+ years the customer was using the circular clarifier and did not have firsthand experience

on Lamella Inclined Plate Clarifier and hence was looking for a reliable supplier with in depth knowledge

on this subject and experience. They floated the enquiry to many suppliers in Indonesia and Eco-Chem

was one of the supplier. The requirement was for a lamella clarifier to handle saturated brine solution

that will operate at 70 deg C plus. The brine is hot and highly corrosive and called for special design of

lamella internals and corrosion resistant coating.

After many interactions and technical discussions and evaluation of ECO design for the challenging application contract was awarded to Eco Chem.

The biggest challenge was space. The available space was very congested and did not have access to move the lamella in to place. The space was surrounded by many tanks, equipment etc.

After site survey and dimensioning Eco Chem made a 3 D modelling of the lamella and simulated the

installation to verify the equipment will fit in after supply and will not foul with other equipment

installed. The margin of error in this case was zero.

Equipment:

Custom built Lamella clarifier designed for 170 m3/h water flow rate and derated for 35 m3/h brine

flow rate. No flash mixing and flocculation tank was provided due to space constraint and in spite of

this fact Eco lamella worked well and met the customer requirement.

Performance guaranteed: - Turbidity - < 5 NTU. Turbidity achieved < 4 NTU. The supplied Lamella met

exceeded the customer expectations more than the specified outlet parameters and the system was

installed and commissioned with 12 days of start of work.

Eco Chem was appreciated by the customer for this successful project. OUTLET AND INLET SAMPLE – (Dosage 2 ppm of Anionic Poly)
