Ecodosing - Effective Biofouling Control

Increased reliability of cooling water systems at lower OPEX

Page last modified
Friday, May 7, 2021 - 16:18

The site-specific biocide dosing solution, 'Ecodosing', targets biofouling in once-through and open recirculation cooling water systems and prevents both macrofouling (shells) and microfouling (biofilms). The Ecodosing solution is delivered in combination with a monitoring system that can detect the onset of biofouling in an early stage and with high accuracy. The total solution will maintain the integrity of the cooling water system, thereby significantly increasing the uptime of the oil & gas processes it supports, while lowering the OPEX related to biocide dosing.

The solution has been successfully implemented since 1998 mostly in Europe and the Middle East with clients in the oil & gas industry, power industry, and desalination industry. Operators that have deployed the technology have seen reductions in cooling water system leak frequencies as high as from 20/yr to zero/yr. 

Case Study H2O Biofouling Services B.V.

Pro/con

Estimated increase in system reliability (uptime): 10-30%
Reduced biocide use by 30-60%, leading to OPEX cost reductions of >€250k/year
Acknowledged by the EU and RSB (Abu Dhabi) as Best Available Technique
Average pay-back time of the investment: 3 months to 1 year
Environmental benefits in terms of energy consumption and discharge water quality
Reduced CO2 emissions (1.000 kton - 5.000 kton per year)
1-3 months study required to understand seasonal variability of the biological content of the local surface water

Specification

Accuracy The solution is based on accurate site-specific conditions like species and seasonal changes.
Areas of Application Industrial cooling water systems.
Capacity Reduced biofouling leads to higher production capacity (debottlenecking).
Collaboration The solution is developed in collaboration with site staff, chemical suppliers and local experts.
Impact Increased system reliability (uptime): 10-30%.
Implementation time Implementation can be within 3 months.
Insight The biomonitors provide real-time insight in the effectiveness of the (current) dosing method.
Maintenance Reduce maintenance as cooling water system stays clean (extended inspection intervals).
OPEX OPEX can be significantly reduced (€500k per year - €1M per day).
Return on Investment The average payback time of the ecodosing solution is 3 months – 1 year.
