Description
lamella clarifier for Chemical & Petrochemical Wastewater – Heavy-Duty Solids Removal for Industrial Effluents
WHAT IS LAMELLA CLARIFIER
Chemical and petrochemical wastewater presents unique challenges for treatment. The streams can be highly variable in composition, pH, temperature, and contaminant load. Suspended solids may include catalysts, precipitated metals, chemical precipitates, and organic by-products. The water chemistry can be aggressive, requiring corrosion-resistant materials. Treatment systems must be robust, reliable, and capable of handling the demanding conditions of chemical processing.
The DAGYEE Lamella Clarifier for Chemical & Petrochemical Wastewater is specifically engineered for these challenging applications. It provides high-efficiency solids removal from aggressive chemical streams, with construction materials selected for resistance to the specific wastewater chemistry. Whether you are treating refinery effluent, chemical plant wastewater, or process water from petrochemical production, this clarifier delivers consistent performance.
The system is designed to handle varying flow rates and solids loading while producing clarified water that meets discharge standards or is suitable for reuse. Its compact design saves valuable plant space, and its simple, reliable operation minimizes maintenance requirements.
HOW DOES LAMELLA CLARIFIER WORKS
The lamella clarifier uses the same basic principle of inclined plate sedimentation, but with specialized features for chemical applications.
The Process Flow
Step 1: Feed Conditioning
Chemical wastewater enters the system, often after pH adjustment, coagulation, and flocculation. Chemical dosing may be provided to optimize solids removal.
Step 2: Chemical Addition (If Required)
For applications requiring chemical precipitation of metals or other dissolved contaminants, chemical reagents are added to form precipitates that can be settled.
Step 3: Lamella Clarification
The conditioned water flows upward through the inclined plate pack. The high effective settling area captures solid precipitates, catalyst fines, and other suspended particles. The clarified water overflows from the top of the unit.
Step 4: Solids Collection and Discharge
Settled solids slide down the plates to the sludge hopper. The concentrated sludge is discharged through a valve or pump system for further processing or disposal.
Step 5: Clear Effluent
The clarified water is discharged to the next treatment stage or to outfall, meeting permit requirements.

Installation Options
Full-Flow Installation
The clarifier is installed in the main cooling water return line, treating the entire flow before the water enters the cooling tower or heat exchangers.
Side-Stream Installation
A portion of the circulating cooling water is diverted through the clarifier and returned. This is a cost-effective approach for maintaining overall system cleanliness without treating the entire flow.
Make-Up Water Treatment
The clarifier is installed on the make-up water line to remove suspended solids before they enter the cooling system.
Pre-Filter Installation
The clarifier is installed ahead of heat exchangers or condensers to provide immediate protection against particulate fouling.
