Flocculant Dosing System Supply for Project “Pemasangan Purwarupa Breakwater GI – Tube Flocculant di Pantai Mundu Cirebon”

Project Overview

This project supported the development of a prototype breakwater using Geotube technology at Mundu Beach, Cirebon. REKA supplied and installed a flocculant dosing system to improve sludge dewatering performance before geotube filling. The system was engineered to enhance solid-liquid separation efficiency under coastal working conditions. Installation and commissioning were carried out with a strong focus on operational reliability, process efficiency, and site adaptability.

Project Objective
The primary objective of this project was to improve sludge dewatering efficiency to ensure optimal geotube filling quality. Proper flocculant dosing was applied to produce stable sludge solids, reduce free water content, and enhance the structural integrity of the geotube-based breakwater.

Project Scope
1. Engineering & System Design 

• Assessment of sludge characteristics and dewatering requirements

• Selection of a suitable flocculant type and dosing capacity

• System design tailored to the geotube breakwater application

2. Supply & Installation

• Supply of dosing pumps, solution tanks, and control components

• Installation in coastal and open-field working conditions

• Integration with existing sludge dewatering operations

3. System Setup & Optimization

• Adjustment of dosing rates based on sludge properties

• Optimization of floc formation for effective solid-liquid separation

• Prevention of overdosing and underdosing during the operation

Key Outcomes

• Improved sludge dewatering efficiency

• Reduced free water content before geotube filling

• More uniform and efficient geotube filling process

• Enhanced strength and stability of geotube-filled material

• Improved overall effectiveness of the breakwater structure
